Dahlia's toppen doe je door het groeipunt, het bovenste knopje van de hoofdstengel, eruit te knijpen of weg te knippen zodra de plant vier tot zes bladparen heeft gevormd. Dat is belangrijk om ervoor te zorgen dat de dahlia zich vertakt in plaats van recht omhoog groeit. Het resultaat? Een prachtige tuin vol kleurrijke dahlia’s!
In deze blog vertellen we je hoe je dahlia’s moet toppen voor een indrukwekkend resultaat in jouw tuin of border.
Wat betekent dahlia’s toppen?
Toppen betekent simpelweg dat je de hoofdstengel van je dahlia bewust afknipt of afknijpt. Dat is vrij eenvoudig: je verwijdert het groeipunt, het bovenste stukje van de plant, waar de stengel nog zacht is. Daardoor stopt de plant met omhoog groeien en richt hij al zijn energie op de zijscheuten. Meer zijscheuten betekent meer takken, meer knoppen en uiteindelijk veel meer bloemen. Je kunt veel meer sturen op de groei van de dahlia dan je wellicht denkt!
Waarom moet je een dahlia toppen?
Een dahlia die je niet topt, groeit simpelweg recht omhoog. Hij maakt dan één hoofdstengel met een paar bloemen. Prachtig natuurlijk, maar voor een kleurrijke verzameling aan dahlia’s, wil je de plant vertakken. Twee zijscheuten worden er namelijk vier, en vier worden er vervolgens acht.
Meer vertakkingen betekent meer bloemknoppen en een langere bloeiperiode. Zo kun je nog meer én langer genieten van jouw bloeiende tuin vol dahlia’s.
Dahlia’s toppen: zo pak je dat aan
Wacht doorgaans tot je dahlia vier tot zes bladparen heeft gevormd. Bij de meeste planten is dat ergens in mei of juni, afhankelijk van wanneer je ze buiten hebt gezet. De plant staat dan al stevig in de grond en heeft genoeg energie om de klap van het toppen op te vangen. Vervolgens:
Zoek je de hoofdstengel op en volg je deze omhoog naar het bovenste groeipunt.
Knijp je dat groeipunt er met je vingers uit of knip je het af met een schaar.
Laat je de plant daarna zijn werk doen. Binnen 2 weken zie je de zijscheuten.
Wanneer moet je dahlia’s toppen?
Je topt je dahlia normaliter wanneer de plant ongeveer 20 tot 30 centimeter hoog is en minstens 2 tot 4 bladparen heeft. Bij de meeste dahlia's is dat moment ergens in mei of begin juni, afhankelijk van wanneer je ze buiten hebt gezet en hoe warm het voorjaar is.
Tip van Bulbs4You: Wacht niet te lang. Hoe groter de plant, hoe minder energie er overblijft voor de nieuwe zijscheuten die na het toppen uitlopen.
Hoe herken je uitgebloeide dahlia knoppen?
Uitgebloeide dahliaknoppen zijn heel makkelijk te herkennen aan, als je weet hoe je ze moet herkennen. Uitgebloeide knoppen hebben namelijk vaak een puntige vorm, terwijl nieuwe knoppen juist mooi rond en stevig zijn.
Het kan goed zo zijn dat er in één dahliaplant zowel nieuwe als uitgebloeide knoppen zitten. In dat geval is het aan te raden om alleen de uitgebloeide knoppen te verwijderen en de nieuwe met rust te laten.
Wanneer moet je een dahlia uit de grond halen?
Na verloop van tijd geeft de plant zelf aan dat het seizoen erop zit. De bloei neemt af, de stengels worden slapper en zodra de eerste nachtvorst de plant heeft geraakt, verkleuren de bladeren en stengels zwart. Dat is het moment om in actie te komen en de dahlia’s uit de grond te halen. Recent schreven we al eens een blog waarin we dat volledig aan je uitleggen!

Wanneer dahlia uit de grond halen?
by martijn van der vlis on Jun 02 2026
Er komt helaas een tijd dat de dahlia niet meer zo mooi bloeit als in de zomer. Tegen de winter wordt het dan ook tijd om de dahliabol uit de grond te halen. In deze blog vertellen we je wanneer het moment daar is, hoe je het aanpakt en hoe je de knollen veilig de winter door brengt. Zo kun je volgend jaar weer genieten van prachtige dahlia’s.
Waarom dahlia’s rooien en overwinteren?
Dahlia’s uit de grond halen kennen we ook als rooien. Dit doe je op het moment dat de eerste nachtvorst de plant heeft geraakt en de stengels zwart of slap zijn geworden. Dahlia's komen oorspronkelijk uit het warme Mexico en zijn niet winterhard. Door ze op tijd uit te graven en vorstvrij te bewaren, zorg je ervoor dat de energie die de plant dit seizoen heeft opgebouwd niet verloren gaat.
Het mooie? Volgend jaar kun je dezelfde knollen gewoon opnieuw poten en dus opnieuw genieten van een volle, bloeiende plant!
Wat heb je nodig voor het rooien van dahlia’s?
Het rooien van dahlia’s is niet moeilijk. Je hebt in de basis dus niet zoveel spullen nodig:
Een schop of spade om de knollen voorzichtig los te steken
Een snoeischaar om de stengels kort te knippen
Een emmer of bak om de knollen tijdelijk in te leggen
Kranten of droog zand om de knollen in te pakken voor de opslag
Een vorstvrije bewaarplaats, denk aan een schuur, kelder of garage
Wanneer en hoe moet je dahlia’s rooien?
Het juiste moment voor het rooien van je dahlia's is vaak na de eerste nachtvorst. Je herkent het meestal aan de stengels! Die worden dan zwart,slap en de plant ziet er een beetje verslagen uit. Dat is een belangrijk seint. Wacht vervolgens niet te lang daarna, want hoe langer de knollen in bevroren grond blijven, hoe groter de kans op beschadiging.
In Nederland valt de eerste nachtvorst doorgaans ergens tussen oktober en november, maar dat verschilt per jaar en per regio. Hou de weersvoorspelling in de gaten zodra de temperaturen 's nachts richting nul gaan.
Stap voor stap: zo rooi je dahlia’s
Stap 1: Knip de stengels terug tot ongeveer tien centimeter boven de grond
Stap 2: Steek met een schop of spade ruim om de plant heen
Stap 3: Til de knollenkluit voorzichtig omhoog en schud de aarde er af
Stap 4: Laat de knollen 2 dagen ondersteboven drogen op een luchtige plek
Stap 5: Pak de knollen in met krantenpapieren leg ze klaar om te bewaren
Hoe bewaar je dahliabollen?
Om volgend jaar weer volop te kunnen genieten van dahlia’s, is het goed om de gerooide bollen goed te bewaren. Dat doe je het beste in een vorstvrije, donkere en droge ruimte. Waar kun je aan denken? De schuur, kelder of garage waar de temperatuur tussen de vijf en tien graden blijft is prima.
Te koud en de knollen bevriezen, te warm en ze gaan uitlopen of rotten. Leg ze in een kist of bak met droog zand, turfmolm of krantenpapier eromheen, zodat ze niet uitdrogen en niet tegen elkaar aanliggen.
Kun je dahlia’s in de grond laten?
Technisch gezien kan het, maar we raden het in Nederland bijna nooit aan. Dahlia's zijn niet winterhard en kunnen een strenge vorstperiode niet overleven in de grond. De knollen bevriezen, rotten weg en zijn volgend voorjaar niet meer te gebruiken. Wil je zeker weten dat je volgend jaar weer kunt genieten van dezelfde plant, dan is rooien de veiligste keuze.
Meer dahlia’s in de tuin?
Kies voor toppen Toppen is misschien wel de makkelijkste manier om meer uit je dahlia's te halen. Eén kleine ingreep aan het begin van het seizoen, en je plant vertakt zich in plaats van recht omhoog te groeien. Het resultaat is een volle dahlia die de hele zomer door blijft bloeien. Recent schreven we een uitgebreide blog over het toppen van dahlia’s.
Het risico van dahlia’s in de grond houden
Het grootste risico is bevriezing. Zodra de grond diep genoeg bevriest, raken de knollen namelijk beschadigd. Van binnenuit vriezen ze kapot, wat je pas in het voorjaar merkt wanneer er niets uitloopt.
Een tweede risico is rotting. Natte, koude grond in combinatie met de afgestorven stengels trekt schimmel aan. Knollen die de vorst overleven, kunnen alsnog wegrotten voor het voorjaar aanbreekt.
Wanneer plant je dahlia’s weer?
Zodra de kans op nachtvorst voorbij is en de grond voldoende is opgewarmd, is het tijd om je dahlia's weer te poten. In Nederland is dat doorgaans vanaf half april tot half mei, afhankelijk van het weer. Heb je de knollen de winter over goed bewaard, dan kun je ze gewoon opnieuw de grond in! Recent schreven we al eens een blog over de ideale periode voor het planten van dahlia‘s.
Toch nieuwe dahlia’s nodig?
Kies voor kwaliteit Heb je de dahlia's per ongeluk te lang in je tuin laten staan, of zijn de knollen toch niet goed door de winter gekomen? Geen zorgen, bij Bulbs4You vind je een ruim assortiment van meer dan 250 dahliavarianten, direct geselecteerd bij kwekers uit de Bollenstreek.
Je bestelt ze eenvoudig online en we bezorgen ze vervolgens netjes bij je thuis, klaar om te poten zodra de grond weer opgewarmd is.

Dahlia's zijn er in tal van kleuren en soorten. Wist je bijvoorbeeld dat er wereldwijd ruim 57.000 geregistreerde dahlia's zijn? Bij Bulbs4You vind je er 250, waarvan we elk jaar opnieuw de mooiste en sterkste varianten selecteren. Rechtstreeks vanuit de Bollenstreek. In deze blog lees je welke dahlia soorten er zoal zijn.
Hoe worden dahlia's ingedeeld?
Dahlia's worden op meerdere manieren ingedeeld en dat maakt het kiezen soms wat overweldigend. Toch is het eigenlijk heel logisch, zodra je weet hoe het systeem werkt.
De belangrijkste indeling is op bloemvorm. Internationaal worden dahlia's daarvoor ingedeeld in officiële klassen, vastgesteld door de National Dahlia Society (NDS). Daarnaast kun je dahlia's ook indelen op hoogte en op kleur, voor wie een specifiek kleurenpalet met diepte in de tuin wil creëren.
De dahlia kent officieel 14 soorten
Wereldwijd zijn er ruim 57.000 geregistreerde cultivars. Bij Bulbs4You vind je 250 van die dahlia’s, zorgvuldig door ons geselecteerd. Die enorme variatie is ontstaan door eeuwen van kruisen en selecteren, wat heeft geleid tot bloemen in alle denkbare vormen, maten en kleuren. Prachtig natuurlijk!
Maar om daar enige structuur in te brengen, heeft de National Dahlia Society de dahlia officieel ingedeeld in 14 bloemvormen, ook wel klassen genoemd. Elke klasse heeft zijn eigen kenmerken: van de cactus dahlia tot de pompon.
Welke dahlia soort past bij jouw tuin?
Eerlijk is eerlijk, kiezen uit 250 mooie varianten met allerlei kleuren is geen makkelijke opgave. Toch zijn er een paar simpele vragen die je al een heel eind op weg helpen:
Hoe groot is je buitenruimte? Heb je ruimte in een ruime border of heb je te maken met siergrassen? Dan kun je alle kanten op. Heb je potten op een terras of balkon? Dan wil je juist weer een compacte, laagblijvende soort.
Wat wil je ermee doen? Dahlia's als snijbloem voor in een vaas vragen om lange, rechte stelen. Wil je de tuin laten stralen? Dan zijn enkele dahlia's of waterlelie-types vaak het aantrekkelijkst voor bijen en vlinders.
Welke sfeer wil je creëren? Wil je overweldigd worden door kleur? Of hou je het liever rustig en sfeervol? Die vraag bepaalt hoe jouw tuin of border er straks bij staat.
Dahlia soorten op kleur, welke kleurgroepen zijn er?
Roze, oranje, rood, wit. Je kunt met dahlia’s qua kleur veel kanten op. Om onderscheid te creëren, worden ze vaak in kleurgroepen ingedeeld. Het helpt je ook bij het samenstellen van een border die écht klopt.
Wanneer en hoe plant je dahliaknollen?
Dahliaknollen plant je buiten als de nachtvorst voorbij is. In Nederland is dat meestal vanaf half mei. Recent schreven we al eens een blog met daarin uitgebreide tips over het planten van dahlia’s.
Wanneer bloeien ze? Reken op de eerste bloemen zo'n 8 tot 10 weken na het planten. Wie in mei plant, ziet in juli de eerste kleur en vanaf augustus gaat het vervolgens hard. Dahlia's bloeien meestal door tot de eerste nachtvorst!

Veelgestelde vragen over dahlia soorten
Welke dahlia soort is het makkelijkst voor beginners?
Enkele dahlia's en decoratieve dahlia's zijn over het algemeen het makkelijkst voor beginners. Ze groeien voorspoedig, bloeien rijkelijk en hebben weinig extra verzorging nodig. Een goede plek in de zon en regelmatig water. Meer heb je eigenlijk niet nodig om te beginnen.
Kun je verschillende dahlia soorten combineren in één border?
Verschillende dahlia soorten combineren in een border kan zeker! Dat levert juist de mooiste resultaten op. Combineer bijvoorbeeld een hoge decoratieve dahlia als blikvanger met lage pompondahlia's ervoor.
Wanneer beginnen dahlia's te bloeien?
Reken op de eerste bloemen zo'n 8 tot 10 weken na het planten. Wie in mei plant, ziet in juli de eerste kleur verschijnen. Vanaf augustus gaan de meeste dahlia's pas echt los.
Moeten dahlia knollen elk jaar uit de grond?
In Nederland moet je knollen elk jaar uit de grond halen. Dahlia's zijn namelijk niet winterhard en overleven de vorst niet in de grond. Haal de knollen na de eerste nachtvorst uit de grond, laat ze drogen en bewaar ze vorstvrij op een droge, donkere plek. In het voorjaar plant je ze opnieuw!
Zijn dahlia's giftig voor mensen of huisdieren?
Dahlia's zijn licht giftig voor honden en katten. Inslikken kan leiden tot maagklachten. Voor mensen zijn ze niet gevaarlijk, maar sommige mensen reageren gevoelig op het sap bij huidcontact. Houd dit in gedachten als je huisdieren hebt die graag in de tuin snuffelen.

The beauty of hydrangeas is that you can actually plant them all year round, as long as it's not freezing! But to be honest: spring (March/April) or autumn (September/October) are the very best times. In this blog, we write extensively about the hydrangea and tell you everything you need to know to make these beautiful shrubs shine in your garden.
When to plant hydrangeas for the best results?
Actually, you can welcome hydrangeas into your garden all year round, as long as Jack Frost hasn't frozen the ground. However, there are two moments that are favorites at our nursery: spring and autumn. Planting in the autumn? Then the plant still has the residual heat of the summer in the soil to grow strong roots for the winter. Choosing spring, between March and May? Then you give the plant a flying start for the new growing season.
Grower's tip: Make sure to place them in a spot where they aren't in the harsh midday sun all day; it makes the leaves a bit tired.
When does the hydrangea bloom?
The hydrangea is a true summer guest that takes over as soon as most spring bulbs have finished their flowering period. Most varieties start their spectacular show around June or July. The beauty of the hydrangea is that the bloom lasts incredibly long.
You can often enjoy those large, colored flower heads deep into September or October. And did you know that even the faded flowers turn beautiful colors in the autumn? We often leave them in the autumn because they look very atmospheric in the garden with a layer of frost in the winter.
Hydrangea care: Tips for a happy plant
If there’s one thing that makes a hydrangea happy, it’s water. The official name isn’t Hydrangea for nothing—it literally means 'water vessel'! Here are our best tips:
Drink plenty: Especially on hot summer days, your hydrangea gets thirsty. Preferably water them early in the morning or late in the evening, directly at the roots.
Give them a little extra: A hydrangea grows and blooms vigorously, so a bit of organic fertilizer in the spring works wonders.
Blue or pink?: Did you know you can control the color of some hydrangeas? In acidic soil they turn blue, and in alkaline (lime-rich) soil they turn pink. A fun experiment for the gardener!
When should you prune hydrangeas?
Pruning is easier than you think, as long as you look at the variety:
Mophead/Lacecap Hydrangeas: Only prune these very lightly in March by cutting away the old flower heads just above the first fat bud.
Panicle Hydrangeas or 'Annabelle': You can safely prune these back hard in early spring to about 20-30 centimeters above the ground. They bloom on 'new wood'.
Step by step: Planting your hydrangea
Planting a hydrangea is a rewarding task. Since they love fresh, moist soil, here is how we do it:
Choose a spot in partial shade. They love the morning sun.
Submerge the hydrangea, pot and all, in a bucket of water first.
Dig a hole about twice the size of the pot.
Mix the excavated soil with some acidic potting soil or specific hydrangea soil.
Remove the plant from the pot and place it in the hole. Ensure the root ball is level with the ground surface.
Fill the hole with soil, press lightly, and give it a generous soak immediately.
Combining hydrangeas in the border
Hydrangeas are true team players. Think of combinations with peonies, gladioli, and dahlias. Our golden tip: plant them behind your spring bulbs. When the tulips and daffodils have finished blooming, the hydrangea's large leaves take over and hide the dying foliage. Are you also getting started with dahlias? We previously wrote a blog about planting dahlias.
Hydrangea in pots: Tips for patio and balcony
Do you have a balcony or terrace? Don't worry, the hydrangea does fantastic in a pot:
Choose a spacious pot: Always ensure there are holes in the bottom for drainage.
Fresh nutrients: Use high-quality potting soil and perhaps clay pebbles (hydro granules) at the bottom of the pot.
Compact varieties: For pots, we often recommend more compact varieties that stay sturdy and low-growing.
Buying hydrangeas? Choose quality

Frequently asked questions about hydrangeas
Why are my hydrangea leaves drooping?
The hydrangea is a heavy drinker. On hot days, the leaves evaporate more water than the roots can supply. Give them a good soak at the roots immediately, and they will look fresh again quickly.
Should I leave the faded flowers on in the winter?
Yes! The old flower heads protect the new buds from frost and look beautiful with a layer of frost on them. Don't cut them away until March.
My hydrangea is getting too big for its spot, what now?
You can easily rejuvenate a hydrangea through 'renewal pruning'. Each year, cut about a third of the oldest branches deep to the ground. This way, within three years, you'll have a fresh shrub without missing a year of flowering.

Do you also get that summer feeling whenever you think of dahlias? We certainly do! Naturally, we’d love to get started in the garden as soon as possible, but with dahlias, patience is a virtue. Dahlias are true sun-worshippers and they absolutely hate the cold. The golden rule we always follow at the nursery is: only plant them outside once the risk of night frost has passed. In this blog, we’ll tell you more about it.
When to plant dahlia bulbs?
To fully enjoy beautiful dahlias in the summer, we always recommend: plant them as soon as the soil has warmed up nicely in the spring. Choose a lovely sunny spot in your garden, as that’s where they’ll be happiest. Next, dig a shallow hole. The tuber only needs to be a few centimeters underground. This way, it can feel the warmth of the spring sun directly and will sprout much faster.
When does the dahlia bloom?
This is exactly why we are so in love with the dahlia: they give you a true explosion of color when most other garden plants have already finished! Dahlias start blooming around July and continue tirelessly deep into autumn, often until the first night frost in October or November. It’s the ultimate way to hold onto that wonderful summer feeling in your garden or on your balcony for even longer.
How to maintain dahlias?
A dahlia is actually very easygoing. The secret? A little extra love and attention is directly rewarded with even more flowers. With these simple tips, you can enjoy them all summer long:
Keep watering: Especially on hot, dry summer days, they get thirsty. It’s better to give them a good soak at the roots a few times a week than a little bit every day.
Deadheading: Cut off faded flowers immediately. The plant will then stop putting its energy into making seeds and focus on creating even more new flower buds.
Support: Some varieties grow beautifully tall and become heavy with flowers. Give these a helping hand in time with a garden stake so they don’t blow over in a strong summer breeze.
Cut flowers: Don’t forget to occasionally cut a few beautiful blooms for a vase on your table. It brings the cheerfulness indoors, and the plant will simply grow new flowers anyway.
How to plant dahlia bulbs correctly?
Planting dahlia tubers isn’t difficult. It’s a delightful task where you can already feel a bit of summer in your hands. Because dahlias are tubers that love warmth, we handle them slightly differently than, for example, tulips. We’ve mapped it out for you step-by-step:
Choose a spot in the garden that gets at least 6 hours of sun a day.
Dig a spacious planting hole about 10 to 15 centimeters deep.
Carefully place the tuber in the hole with the old stem pointing upwards.
Maintain a planting distance of 40 to 50 centimeters between the tubers.
Cover the tuber with the excavated soil and press it down very lightly.
Water the tubers immediately after planting.
Combining dahlias with other summer bloomers
Dahlias are real eye-catchers on their own, but they truly shine when placed alongside other summer friends. Think of gladioli, hydrangeas, or peonies! Speaking of hydrangeas, we previously wrote a blog about planting dahlias (Note: the link in the original points to hydrangeas, but the text says dahlias—please verify).
By combining dahlias with plants that bloom slightly earlier or later, you ensure your garden is a colorful party from early spring until the first night frost. One tip we’d like to give: ensure enough space between the tubers for optimal growth. Keep in mind: most hydrangeas love (partial) shade and lots of water, while dahlias are true sun-worshippers.
Planting dahlias in pots
Don’t have a large garden? No worries! Dahlias also do excellently in pots on the patio or balcony. Here’s how you do it:
Choose the right pot: Use a spacious pot with holes in the bottom so excess water can easily drain away.
A good start: Always use fresh potting soil with enough nutrients.
Compact varieties: While almost all dahlias can grow in pots, we often recommend the more compact varieties for tables or small balconies. These stay nice and sturdy and low-growing.

Frequently asked questions about planting dahlia bulbs
What is the best location for dahlias?
For the most beautiful sea of flowers, the golden rule is: the more sun, the more blooms. Additionally, make sure they are sheltered from the wind and don’t have "wet feet" (poor drainage).
Can dahlias stay in the ground during winter?
Dahlias originally come from warm Mexico and therefore do not handle frost well. In many regions, we recommend carefully lifting the tubers from the ground after the first night frost and storing them in a frost-free place.
Why are there no flowers on my dahlia?
This can have a few causes. The most common is a lack of sunlight. Dahlias really need those 6 hours of sun a day to produce buds. Another reason could be too much nitrogen in the fertilizer. Our tip? Use a fertilizer with more potassium; it stimulates blooming!

Spring planning: When is the best time to plant peonies?
by Niels Horstink on Oct 06 2025
The best time to plant peonies is a question that occupies many gardeners. These beautiful flowers add color to any garden. However, there's more to planting and caring for peonies than you might think. With the right knowledge, you can enjoy years of vibrant blooms and healthy plants. This blog post explains exactly how to plant, care for, and propagate peonies.
Peony varieties and their differences
Peonies are roughly divided into two groups: herbaceous peonies and tree peonies. Herbaceous peonies die back above ground in winter and reappear in spring. Tree peonies have woody stems that remain above ground in winter. They often grow much larger than regular peonies. Tree peony flowers appear from mid-April to June and are often red or yellow. A mature tree peony can reach a height of 1.75 meters, making it a real wow factor in the garden.
Herbaceous peonies are smaller and very suitable for borders or mixed plantings. Both varieties are beautiful, but differ in height and care.
The right time to plant peonies
Peonies can be planted in both autumn and spring. Autumn is often preferred because the plant can establish roots throughout the winter. This gives the peony a strong foundation in spring and a greater chance of abundant blooms. However, spring is also fine, as long as the soil isn't too wet or too cold.
When planting in spring, it's important to water the plant thoroughly right away. This allows the roots to establish more quickly. In autumn, extra watering is less necessary, but you should still check the soil.
How to plant peonies: in the ground or in a pot
Peonies can be planted either directly in the ground or in a large pot. Both methods have their advantages. In the ground, peonies have plenty of room to grow. Not everyone has space in the ground. By planting them in a pot, you can also enjoy the beautiful, colorful flowers. Moreover, you can easily move them around in the pot. Below, you'll find a step-by-step explanation of both options.
Planting peonies in the open ground:
Dig a hole 10 to 15 centimeters deep and twice as wide as the root ball.
Loosen the soil so that the roots can grow well.
Mix the excavated soil with compost or manure for better soil structure.
Place the rhizome in the hole. Make sure the "eyes" are no deeper than 5 centimeters (2 inches) below the surface.
· Maintain sufficient distance between the plants, about 90 to 120 centimeters. This gives them room to fully develop and prevents mold.
· Backfill the hole and press the soil firmly.
· Water the plant when planting so the roots absorb nutrients immediately. Continue watering regularly during dry periods, but avoid allowing the soil to become too wet .
Planting peonies in pots:
Choose a large pot of at least 40 to 50 centimeters in diameter with holes for drainage.
Fill the pot with airy potting soil and, if necessary, mix in sharp sand or perlite for good drainage.
Place the rhizome in the pot with the 'eyes' no more than 5 centimetres below the ground.
Fill the pot with potting soil and press the soil lightly.
Place the pot in a sunny spot where the plant will get at least six hours of light.
Water regularly , but avoid allowing the soil to remain constantly wet.
Location and sunlight for peonies
A peony grows best in a bright spot. Ideally, it should receive at least six hours of sunlight per day. The more sun, the more abundant the blooms. If you place the peony in a shady spot, fewer flowers will appear.
Also, make sure the soil drains well. Peonies don't like wet feet. Therefore, choose loose soil and avoid areas where water stagnates.
Pruning peonies in the fall
September and October are the best times to prune your peonies. Remove old and discolored stems. Always leave at least two strong stems so the plant can sprout again next year.
Is the peony growing too large? Then you can remove older branches. Leave the younger stems. That way, it will bloom profusely again later.
When does the peony bloom?
Peonies bloom from mid-April to mid-June. During this period, you'll enjoy beautiful, large flowers that brighten up your garden. Depending on the variety, the colors can range from white to deep red.
During this period, provide sufficient water and keep weeds away from the plant. This will ensure the roots receive all the nutrients they need and promote longer flowering.
Are peonies winter hardy?
Fortunately, peonies are winter-hardy. So they can stay in the garden, even during cold nights. However, the above-ground parts die back in winter. The plants will sprout again in spring.
Protection is usually not necessary, except for young plants. In that case, you can spread some mulch or leaves around the roots. This provides extra protection during severe frost.
Colors and symbolism of peonies
Besides their beauty, peonies also have a rich symbolism. In many cultures, they symbolize love, wealth, and prosperity. This makes them beloved not only for gardens but also as gifts.
The flowers are available in a variety of colors, from bright white to deep pink and deep red. Each color gives the garden its own unique atmosphere.
Combine with other plants in the garden
Peonies are real eye-catchers, but they look even better with the right companions. Pair them with lavender, for example, for a beautiful contrast of color and scent. Ornamental grasses also create a playful effect alongside the full blooms.
Flower bulbs like tulips or daffodils perfectly complement the peony blooming season. This way, you can enjoy color early in the spring, followed by the rich blooms of the peony.
Tips for longer flowering and healthy plants
A vigorously growing peony will produce abundant flowers for years. These steps will ensure abundant blooms and keep the plant healthy.
Cut off faded flowers: Remove the spent buds immediately. Cut back to just above a pair of healthy leaves.
Fertilize lightly in spring: Use organic fertilizer in March or April. Apply sparingly to prevent soft growth.
Water regularly: Keep the soil slightly moist during the growing season. Avoid puddles and wet roots.
Apply a mulch layer: Spread a thin layer of compost around the plant in April. Mulch retains moisture and nourishes the soil.
Provide plenty of sun and air: Choose a spot with at least six hours of sun per day. Allow plenty of room for air circulation.
Support heavy stems: Place stakes or stakes on large varieties in good time. This will keep the flowers upright.
Keep the leaves clean and healthy: Remove diseased or brown leaves immediately. Clean your pruning shears after use.
Prune carefully in the fall: Cut away unsightly stems in September or October. Leave at least two strong stems.
Don't transplant unnecessarily: It's best to leave peonies in the same spot for years. They don't like being moved frequently.
Divide older plants when necessary: Divide large clumps in autumn or early spring. Ensure each section produces three shoots and strong roots.
Don't feed too much nitrogen: Avoid high doses of fast-release fertilizer. Too much nitrogen produces foliage but fewer flowers.
Protect from extreme drought or heat: Provide plenty of water during warm periods. Temporarily protect with fleece if necessary.
This routine will help your peony grow strongly, resulting in fuller, longer blooms each year.
Peonies as cut flowers
Peonies are incredibly popular in bouquets. Cut the stems when the buds are still half closed. This way, they'll last longer in the vase.
Always use a clean vase and fresh water. Cut the stems diagonally for better water absorption. This way, you can enjoy the peony's full splendor indoors, too.
Propagating peonies by division
Want more peonies in your garden? You can divide older plants. Do this in early spring or autumn. First, cut away dead stems and divide the root ball. Each division should have at least three shoots and plenty of roots.
After dividing, you can replant the pieces in a suitable location. Tree peonies cannot be propagated this way because they have woody stems.
Frequently asked questions about peonies
How long can a peony stay in one place? Peonies can grow in the same spot for decades. Transplanting is usually not necessary.
Why isn't my peony blooming? This can be caused by planting too deep, not enough sun, or plants that are too young. Sometimes it takes several years for flowering to occur.
Can you plant peonies in the shade? They do grow in shade, but produce fewer flowers. Sunlight is essential for abundant flowering.
Go for color, go for quality: peonies from Bulbs4you

When to plant tulip bulbs for a colorful spring
by martijn van der vlis on Sep 05 2025
When to plant tulip bulbs? That's a question many gardeners ask as soon as summer is over. Tulips are one of the most popular spring flowers, bringing color, cheerfulness, and variety to any garden. With the right timing and care, you can enjoy a beautiful field of flowers in spring, whether planted in the ground or in pots on the patio.
The best time to plant tulip bulbs
The best time to plant tulips is between September and December, before the first frost. During this period, the bulbs have plenty of time to establish roots and prepare for spring.
Are you late? No problem. You can still plant them in January or February, as long as the ground isn't frozen. Tulip bulbs are winter-hardy, meaning they can tolerate low temperatures well. Just keep in mind that flowering will start a little later in that case.
Location and soil type for healthy tulips
A sunny spot is ideal for planting tulip bulbs. The more sun the flowers receive, the better they will grow and bloom. Always ensure the soil drains well to prevent bulb rot.
If you have heavy clay soil, mix it with sand and compost to improve its structure. For light, sandy soil, adding compost will help retain moisture better and increase its nutrient content.
Explanation of planting tulip bulbs
Planting tulip bulbs is simple, but requires some attention to detail. Below, we'll explain it step by step:
Choose a sunny spot with well-drained soil.
Improve the soil if necessary with compost and possibly some sand.
Dig a planting hole about 20 centimeters deep.
Place the ball with the point facing up.
Leave about 5 centimetres of space between the bulbs.
Cover with soil and press lightly.
Water the bulbs
Types of tulips and flowering time
There are over 3,000 registered tulip varieties, classified as early, mid-early, and late bloomers. By combining different varieties, you can extend the flowering period in your garden from March to May. Early tulips provide color as early as March, while late varieties don't bloom until May.
Besides the blooming period, there's also a huge variety of shapes and styles. The single tulip is classic and timeless, while the double tulip produces a full, lush bloom. Parrot tulips command attention with their strikingly serrated and colorful petals. French tulips are known for their extra-long stems and elegant appearance. By cleverly combining them, you can create a garden that not only blooms for a long time but also offers a variety of colors and shapes.
Tulips as mood setters in any type of garden
Tulips are more versatile than many people think and fit into almost any garden style. In a modern garden, neat rows of red or white tulips create a stylish and minimalist effect. If you have a more rustic garden, a vibrant mix of colors and varieties will be much more effective. Tulips blend effortlessly into the ambiance of their surroundings and always bring a cheerful touch.
Even small gardens or even balconies benefit from tulips. In pots and containers, you can easily combine different colors or choose a single, striking shade. By cleverly playing with heights and flowering periods, you can create a vibrant ensemble. Tulips are not only spring classics but also true mood-makers that make any outdoor space special.
Combine tulips with other spring bulbs
Tulips look beautiful on their own, but they look even better when combined with other spring bulbs, such as daffodils , hyacinths, and alliums . These plants have similar planting times and often bloom slightly earlier or later than tulips, giving you more color in your garden.
A popular technique is "layered planting" (also called lasagna planting). This involves planting bulbs in layers on top of each other, so that new flowers continually emerge.
Planting tulip bulbs in pots
Don't have a large garden? Tulips also grow well in pots and containers. Always use pots with a drainage hole and place a layer of gravel or pot shards at the bottom for good drainage.
Plant the bulbs at the same depth as you would in the ground, and preferably place the pots in a sheltered spot. In severe frost, you can bring them indoors temporarily or cover them with bubble wrap.
Planting tulip bulbs with children: an educational activity
Planting tulip bulbs is a surprisingly fun activity to do with children. The digging, holding the bulbs, and covering them with soil makes it tactile and playful. Children also learn something about nature and the seasons. The prospect of colorful flowers appearing in the spring where they helped makes it even more special.
You can even make it a small project. Give each child their own patch of ground or pot, so they feel responsible for their own flowers. It's a simple way to bring children closer to nature and encourage their patience and care. And when the first tulips appear, the pride in their work is often priceless.
Post-flowering maintenance
After flowering, it's important to leave the tulip foliage until it has completely withered. This allows the bulb to store nutrients for the following year. Only cut off the spent flowers to prevent seed formation.
If you want to dig up the bulbs, do so as soon as the foliage has died back. Store them in a cool, dry place until the next planting season.
Famous tulip fields in the Netherlands
The Netherlands is world-renowned for its tulips. Places like Keukenhof, the Bollenstreek, and the Noordoostpolder attract thousands of visitors every year. Here you can find inspiration for color combinations and planting plans for your own garden.
Enjoy your colorful spring garden
With the right preparation and the right planting time, planting tulip bulbs is an investment in months of gardening pleasure. Whether you choose a single variety in a neat border or a colorful mixture scattered throughout the garden, tulips will always bring a smile to your face.

General information about flower bulbs
by Sabine Geerlings on Jan 23 2024
When winter is at its peak, the beautiful snowdrops and crocuses announce the approaching spring. They are the first flowers in a series of bulbous plants that will give your garden cheerful colors. The tips below will help you enjoy your flower bulbs more.
Location
Depending on the type, you can plant flower bulbs in flower beds, borders or containers. Preferably plant bulbs that can naturalize between trees or shrubs, where they can remain and reproduce themselves. Place hyacinths and tulips in groups between the perennials. In May or June you can beautifully plant the open spaces with annual summer flowers.
The ground
Flower bulbs are happy with any type of soil, as long as it is well-drained. Lighten heavy soil with peat moss or mix some compost into the soil.
Plants
Flower bulbs that bloom in spring, such as tulips, daffodils, hyacinths and crocuses, can be planted from mid-September to November/December. The varieties that bloom in summer or autumn, such as dahlias, cannas and lilies, go into the ground in the spring. Bulbs are not planted very deeply and this is stated on the packaging. As a rule of thumb, a planting hole depth is equal to three times the maximum diameter of the bulb. However, there are so many exceptions to the rule that it is therefore better to check carefully before planting which planting depth applies to the bulbous plant that has been purchased. You can find this information on the packaging.
On the balcony
Even if you don't have a garden, you can herald spring early with flower bulbs. Plant them in the containers where you put the summer flowering bulbs in May. While flower bulbs in the garden are often more beautiful in groups of one species, on a small balcony it can really come into their own to mix various species and thus enjoy an exuberant display of color on the square meter in the spring.
Did you know?
The months are often indicated on seed packets with Roman numerals. I = January, II = February, III = March, IV = April, V = May, VI = June, VII = July, VIII = August, IX = September, X = October, XI = November and XII = December.

Why you should plant your flower bulbs now for beautiful flowers in the spring
by Sabine Geerlings on Jan 23 2024
Spring may seem far away, but now is the time to plant your flower bulbs. Read below for three reasons why you should start planting now!
1: The period in which most growers and garden enthusiasts plant their bulbs is between mid-September and mid-December. This period is also called the 'bulb planting time'. This is partly because the soil is still quite warm in autumn. Think of it as a warm bed in which you plant the bulbs, they are immediately put to work.
2: There is a lot of rain in autumn. The soil is therefore much moister. This means that your bulbs need less help from you to catch on properly. So it takes you much less time to care for your bulbs. In the spring you will have to start watering again to help them grow and survive.
3: Plant now and enjoy later! With a bit of luck you can already see snowdrops in your garden in January. This is followed by tulips, daffodils, crocuses, irises and all other spring bloomers! This way you can enjoy a colorful garden early on.
Are you convinced and do you want to get started planting flower bulbs? Follow these steps to plant them correctly:
First loosen the soil thoroughly with a spade where the flower bulbs will be planted. Then the soil is easy to work with.
Dig a hole with a spade or bulb planter.
Plant the flower bulbs in the hole with the point up.
Close the hole with the excavated earth and press it down a bit.
Give some water
Good luck!
