After blossoming, tulips can be deadheaded. You risk losing the seed if you deadhead species types. Wait until the foliage turns yellow before pruning it, which will happen approximately a month after flowering. The bulbs will be less resilient the following year if you prune the leaves too soon.
Daniel Haynes provides the following instructions for reflowering species tulips:
How to propagate tulips
It’s preferable to plant new tulips every autumn if you want to enjoy their blossoms every year. The bulbs can also be lifted and stored. Once the leaf has turned yellow a month after flowering, you can accomplish this by lifting them with a hand fork. Take off the stem, pull or cut the foliage, and the bulb’s flaky outer layer. After letting the bulbs dry, keep them in a paper bag.
Watch Monty Don’s instructional video on how to handle and keep tulip bulbs:
You can carefully pluck out offset bulbs that have grown on the sides of the main bulb. These should be kept in paper bags with their parent bulbs in a frost-free, cool location. In the fall, offsets can be planted, but 25 cm deeper.
In the garden, species bulbs will self-seed. Allow the seed to distribute instead of deadheading to stimulate new growth.
Growing tulips: problem solving
Because the spores are carried by wind and rain, the fungal disease known as tulip fire (Botrytis tulipae) is especially problematic during wet seasons. Unattractive brown blotches can be seen all over the plant, as well as distorted and stunted shoots and leaves, which are indications. If any of your plants are impacted, get rid of them, burn them, and wait at least two years before planting tulips there again. Avoid this issue if you are preserving bulbs from year to year by immersing them in a fungal solution. The risk of the disease should be decreased by planting in November.
Should tulip bulbs be lifted?
Gardeners are not required by law to dig up tulip bulbs every year or even at all. The majority of bulbs actually prefer to remain in the ground, where they will bloom the next year if left alone. Tulip bulbs are only dug out by gardeners when the plants appear less robust and produce fewer flowers, which may be an indication of overcrowding.
Dig up your tulips if you think they aren’t doing as well as they did previous year. Discover the best time to dig up tulips before you proceed. It is better to avoid digging up bulbs altogether than to do it at the incorrect moment.
I have tulip bulbs, when should I lift them?
It’s simple to learn how to grow tulips. Even more important is learning how to store tulip bulbs to preserve them. A magnificent springtime display may be created with only a few straightforward steps.
- Once the flowers have faded, deadhead your tulips (unless they are’species’ varieties, which you should foster to distribute their seeds for additional blooming). But resist the urge to remove the vegetation. It can feed nutrients back down into the bulb if it is left undamaged. Wait until the leaves start to yellow and wither, which happens around six weeks after blossoming. The time has come to lift them when this occurs.
- With the foliage still attached, carefully lift the bulbs with a garden fork.
- After being raised, remove any unhealthy or damaged ones and brush off any soil.
- Then, you should place them in trays or a net bag somewhere dim and well-ventilated. Keep plants warm and dry is the greatest thing you can do, according to horticultural expert Monty Don on Gardeners’ World (opens in new tab). “If you can, above 20C [68F].”
- Separate the bulbs once they have dried out. Your principal flowerer for the following year is the large bulb. In the fall, plant this like you would a new bulb. Monty advises growing the smaller plants in pots, labeling them, and removing the flowerheads as they appear the next year. They will bulk up after around three years, at which point you can use them in the garden.
How to Save Tulip Bulbs For A More Colorful Garden Next Spring
One of the most popular flower bulbs is the tulip. They are the center of attention in the spring garden because of their brilliant colors and graceful shapes. Discover tulip bulb preservation techniques to enjoy a second season of beauty.
How to Save Tulip Bulbs
While most tulips won’t rebloom if the bulbs are left in the ground, certain small tulips naturalize well, multiply, and bloom for several years. Digging them up and storing them over the summer is the best option if you want to keep them.
- Dig the tulips up after the foliage has finished withering and dying back after flowering.
- After removing the soil, let the bulbs dry. Throw away those that are broken.
- The bulbs should be kept in paper bags or nets. Before transplanting them in the fall, label them and store them in a cold, dark spot.
How to Save Tulip Bulbs: Propagation
Tulips can be multiplied by propagation, increasing your stock. It’s possible that some of your tulip bulbs have sprung offsets or tiny new bulbs. Split these off from their parent bulbs, and then plant them in pots in a cold frame or in a protected area of the garden, at least 8″ deep. Make sure the soil is wet but not drenched. Be patient; they might bloom in the spring after that or they might need two seasons to mature before they bloom.
How to Save Tulip Bulbs Grown in Pots
Tulips cultivated in pots are less likely to blossom again because flower bulbs are more stressed when grown in pots and containers than when grown in the outdoors. It is preferable to throw them away once they have bloomed and plant new bulbs in the fall.

What happens to tulip bulbs once they have bloomed?
Once the blooms have faded, remove the seed heads to encourage your tulips to blossom once more the following year. After the foliage has naturally died down, dig up the bulbs around six weeks after they have bloomed. Any that are infected or damaged should be discarded after drying. Replant in them in the fall after keeping them in trays or nets in a dark, dry location over the summer.
After blooming, can you leave tulips in the ground?
Some bulbs, like jonquils and daffodils, can be left in the ground year after year with no problems. Tulips should be dug out and let to dry out, though. Some tulip bulbs are not winter-resistant; therefore, in cold climates, those bulbs should be plucked and preserved in order to be used the following season.
Cut the wasted flower stalks off after the blooms are gone, but leave the foliage alone. Tulips should ideally be left in the ground for two to three weeks after flowering because this is when they spend their energy developing sturdy bulbs for the following year’s blooms. The bulb won’t have enough reserves to grow and bloom the following season if you remove the leaves before they naturally wither. Tulips do not need foliar feed to develop the bulb, unlike daffodils.
Take caution when removing them from the ground using a garden fork. You should throw away any bulbs that have physical deterioration.
Place the bulb, clean of any remaining soil, in a single layer in a basket or tray with enough airflow. A paper bag can also be used to keep the bulbs. Particularly if you have various species, carefully mark each bag or tray.
Keep in a well-ventilated, dark, chilly environment. Consistent temperature should be maintained. Regularly inspect bulbs, and take out any that have mildew or rotting symptoms. A smart precaution is to shake the bulbs in a plastic bag with some fungicide.
Store the bulbs until autumn, when you can start to divide and replant them. The best way to feed your tulips is to improve the soil with a top dressing of bone meal in the fall.
Can you leave tulip bulbs in the ground?
Mix three parts multipurpose compost to one part grit to make potting compost. Next, fill your container such that this length is the space between the compost at the bottom and the top edge of the rim. This height is the height of two or three bulbs put end to end. Place the bulbs on top of the compost when it is well leveled, leaving about a finger’s width between each bulb. The remaining compost mixture should be spread over the bulbs, leaving the soil about 2.5 cm (1 in) below the rim. When they start to grow and flower, you may always move them into their final location after giving them adequate watering.
Use three parts loam-based compost, such as Melcourt SylvaGrow with additional John Innes, mixed with one part grit to preserve the tulips in their pots for more than one season. See the RHS guide for additional details on growing bulbs in containers.
Make a “bulb lasagna” by placing two or three layers of bulbs in one pot for a bigger container show.
Planting specialist tulips in containers
Fill containers with a mixture of one part grit and two parts loam-based compost, such as Melcourt SylvaGrow with additional John Innes. Directly beneath the bulbs, a coating of angular sand will aid in drainage and stop bulbs from decaying. To avoid soil splashing flowers and weeds developing, top-dress the pot with grit after covering the bulbs.
Containers outdoors
Before bulbs emerge, if the compost appears damp during rainy weather, relocate the plants temporarily to a protected area next to a fence or house wall or place them in an unheated greenhouse. They can be placed back where they were after the compost has slightly dried. Keep your tulips well-watered if dry weather comes while they are growing (beginning in February or until the leaves show). Poor growth or a shorter flowering time can result from a water scarcity.
In Borders
If there is enough rain to keep the ground moist, tulips in beds and borders typically don’t need watering. Only use water during extended dry spells (greater than two to three weeks), with the goal of keeping the ground moist rather than soggy.
Feeding
Feeding encourages development and flowering while restoring nutrients to the bulb when combined with watering. This promotes healthy flowering of tulips the next year. Feed plants after they begin to grow (about March), using a potassium-rich liquid fertilizer like tomato feed. Once the leaves start to yellow and die back, feeding can be discontinued. There is no need to feed bulbs if you are growing tulips for bedding and discarding the bulbs once they have done flowering.
Deadheading
Tulips can produce seedheads after flowering. Deadheading is the removal of these by severing the stalk immediately above the leaves. You might want to wait until the seedheads are fully matured if you’re planting specialty tulips because some of them can be grown from seed. For information on how to cultivate tulips from seed, see Propagation below.
Encouraging reflowering
When left in the ground, border tulips frequently do not bloom in their second year. They are frequently viewed as seasonal décor (bedding) and removed after flowering because of this. This may seem wasteful, but autumn is a great time to buy bulbs since they are readily accessible, relatively priced, and they produce a more consistent floral display. Some tulips, such as the Darwin hybrids and Kaufmanniana varieties, are worth leaving in the ground since they are more likely to reflower. See our list here for varieties that are more likely to reflower.
Tulip bulbs can be lifted, dried, and stored over the summer to encourage reflowering. This mimics the natural environment where tulips rest throughout the warm, dry summers.
- When the foliage turns yellow, remove bulbs (about six weeks after flowering)
- Place the entire plant or bulb in trays until the leaves become straw-colored if you need to lift early.
- Bulb dirt should be removed, and any that exhibit damage or sickness (such as blue/white mold or mushy flesh when pressed with the thumb) should be thrown away.
- Allow bulbs to completely dry (the brown skin becomes papery)
- In trays or net/paper bags, keep bulbs in a warm, dark, well-ventilated location between 18 and 20 C. (65-68F)
- Replanting bulbs in the fall (September to November)
Replant saved bulbs in less significant beds, borders, and containers because reflowering isn’t always possible, and acquire new ones for more significant or noticeable spots (e.g. by the front door). It’s also a good idea to select the biggest bulbs for prominent spots to guarantee a better display.
Specialty tulips, such as alpine varieties, can be left undisturbed in their containers or the ground, where they frequently expand in quantity on their own.
No trimming or training is required for tulips. Simply cut off the straw-colored wilted stems and foliage in the summer. Typically, stems can be simply removed without needing to be cut.
The purpose of propagation is typically to increase specialized tulips. Border tulips are typically not propagated because it is easy to get affordable, flowering-size bulbs for purchase. However, either can be used with these techniques. You can expand your tulip bulbs in two different ways:
By offsets, we mean young bulbs that grow organically around the main one. When lifting plants, they can be detached and dried preserved over the summer. In the fall, replant offsets at least 20 cm (8 in) deep. It could take three to four years for little offsets to reach flowering size.
By seed: Because Border varieties of tulips don’t typically generate seed, try this method with smaller Specialist tulips. In trays or pots of loam-based compost, such as Melcourt SylvaGrow with additional John Innes, sow papery seed that was harvested this year. Put a thin layer of sieved compost over the seed before finishing with a 1/2 cm (1/4 inch) layer of horticultural grit. Leave the container outside since seeds need to be chilled to germinate. Springtime brings forth seedlings, which normally take three to four years to mature into flowering plants.
In gardens, species tulips like Tulipa sprengeri self-seed under the right circumstances. Additionally, Tulipa sylvestris will grow via stolons (underground stems).
Pests and illnesses can sometimes affect tulips, especially when they are grown in the same soil for an extended period of time. Their health could also be impacted by the conditions of growth.
- Feed plants with tomato fertilizer while they are growing if they don’t blossom. Increased nutrient return to the bulb aids in bloom formation for the next year. Reflowering of border tulips is challenging on moister soils that don’t dry out in the summer.
- Shallow planting results in many tiny bulbs not blooming. Bulbs should be replanted at least three times as deep.
- short-stemmed tulips possibly as a result of late planting or mild winters
- Bulb-digging grey squirrels are common. Use chicken wire to cover bulbs in containers. Plant bulbs in the ground in chicken wire-covered aquatic baskets. Once leaves appear, the wire can be removed.
