When the first signs of greenery appear in the late winter or early spring, treat with granular bulb fertilizer. When bulbs bloom, liquid fertilizer can be applied to the leaves. A 4-12-12 that is sold in our gift shop is what we utilize.
Inspect foliage tips
Check for “fire heads on tulips” in late January and early February. This is seen as gray fuzz on the foliage’s tips. Actually, these are botrytis spores, which can spread to all of your tulips. To control the disease, remove the entire affected plant and bulb and discard them. Botrytis is known as “Fire Flight” because to its quick spread (do not mulch diseased plants; it will only create a bigger problem). Healthy Tulips Infected Tulips
Snap off Heads after bloom
Your tulips must blossom completely before the seed pods may be removed to prevent the flowers from going to seed. In order for the bulb to blossom the next year, all the nutrients and energy in the stem and leaves are able to flow there. The stems should not be bent or tied with a band. Let the stems expire on their own. You can plant annuals and perennials on top of your bulbs to add color for the remainder of spring and summer while the bulbs recover for the next year.
Dig Every 3-4 Years for Ground planting
Tulips don’t need to be dug up and divided every year, but if they were planted in the ground, they should be dug up at least every three to four years. Make sure they are not in a part of the yard where they will be watered all summer if you are not digging them up every year. Your bulbs will rot or die if you water them too much in the summer. Try to water the bulbs once a week or fewer if they are in an area where you must water them.
Tulip bulbs can be left in the ground all year.
In the hardy U.S. Department of Agriculture plant hardiness zones 3 through 8, tulip bulbs can be left in the ground to grow as perennials. They only reproduce when permitted to go through a full leaf cycle and spend the entire year underground. Although they may not fare well in summer in hotter locations, planting them approximately 12 inches deep will protect them from the heat. However, they might spread more slowly at that depth.
What occurs if tulip bulbs are not dug up?
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.
After blossoming, should you dig up tulip bulbs?
These likewise bloom in the spring, although the flowers are often smaller and shorter in height. They are either named cultivars that are closely related to them or wild species. They look delicate and frequently naturalize (grow in numbers) in gardens. Some plants do better in a more protected environment, such a greenhouse or cold frame.
Border tulips
In the fall, nurseries and garden centers sell a variety of border tulips as dry bulbs. They come in labeled bundles or are sold loose. Select bulbs that are sturdy and mold-free. Sometimes the papery brown skin peels off, although this has no impact on flowering. For each sq m (yd) of garden you wish to plant, you should buy between 25 to 50 bulbs to create a really good flowering display (using less than 25 is feasible, but you should underplant with forget-me-nots, pansies, wallflowers, or primroses so that it doesn’t seem gappy). A 45cm (18in) wide pot would need about 12 bulbs for a container, but you can raise this to 20 bulbs for a bigger display.
In the spring, gardening supply stores and supermarkets frequently have bulbs grown in containers available if you missed buying and planting bulbs in the fall. Purchase them ideally before they bloom fully.
Specialist tulips
These are occasionally offered at stores that sell gardening supplies, but you might need to mail order them from an online store or specialized nursery. Use the RHS Find a Plant feature here to locate a supplier.
These tulips, which are also known as English Florists’ tulips, contain petals with multicolored streaking or flaming patterns. The tulip shattering virus is to blame for their appearance (TBV). They can be grown by infecting ‘breeder’ tulips, though they are less usually offered for sale. Visit the Wakefield and North of England Tulip Society for further information. Flame variations like Tulipa ‘Olympic Flame’ have the appearance but are not virus-infected if you like the way these types look but don’t want to breed them.

When to plant tulips
When the plant is dormant in the fall (September to November), dry bulbs are planted. If planting bulbs right immediately is not an option, keep them in a cool, dry spot. Plants purchased in containers from garden merchants in the spring are planted immediately and will bloom in a few weeks.
These are used as bedding plants for spring color because they often only flower dependably the first year. It is not necessary to have proper soil for bedding because bulbs will bloom just fine in any condition as long as the land is not flooded. Once the bulbs have completed flowering, they are pulled up. Some tulip cultivars can, however, be left in the ground and will frequently continue to bloom for several years (see Tulips that last more than one year). In this case, well-drained soil in direct sunlight is more crucial because it will make the display last for longer.
For spring color, bulbs can be planted in containers to brighten up paved areas and serve as brilliant focal points, as well as in borders between perennial plants (which continue the seasonal display by blossoming later in the year). Alternately, use tulips into a bedding design together with other spring-flowering plants. For greater impact, plant low-growing flowers that bloom at the same time as tulips, such as pansies, primroses, and polyanthus, as well as forget-me-nots (Myosotis sylvatica), wallflowers (Erysimum cheiri), and primroses (Viola).
Cut tulips from the border are excellent. To make choosing easier, grow in rows. Cut flowers as soon as the bud begins to display color but before it fully opens.
These often need particular growing circumstances. Planting in gravel and rock gardens (where the soil is free-draining) and in pots in greenhouses can provide some of the conditions that some plants require, including very good drainage and full sun (in free-draining compost). Plant other tulips behind bushes and trees because they prefer part-shade and moist soil (for shade).
This list offers extra information about a number of commonly found specialized tulips:
- Although they can be cultivated in greenhouses, Tulipa ophanidea Whittallii Group, T. kolpakowskiana, and T. saxitilis Bakeri Group prefer good drainage and full sun. Due to their slightly bigger size, they would also do well in gravel or rock gardens.
- In pots of freely draining grit in your greenhouse, little alpine species like Tulipa turkestanica and T. hageri ‘Splendens’ are probably best grown. Their blossoms can be admired at eye level on the greenhouse bench while being protected from the elements here.
- The tulip species Tulipa sylvestris and T. sprengeri may both grow in partial shade on moist soil. Grow them in wet borders in the garden under some deciduous trees or bushes for shade (those that lose their leaves in winter). In grassy areas or meadows, where their population can grow, it is also worthwhile to try to naturalize them.
What happens to tulips once they have finished blooming?
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.
How can I store my potted tulip bulbs for the following season?
Cut off the flower stalk’s top as the tulip flowers fade to prevent the plant from setting seed. Maintain a wet but not soggy soil. The green leaves must be kept on the plants because they absorb energy from the sun. Place the potted plant in a space with plenty of direct sunlight and a cool climate. Allow the leaves to naturally turn yellow and wither away. The technique enables the bulb to store energy for growth the next year.
Do tulips grow in numbers?
The majority of the tulip bulbs we purchase have been cultivated, nurtured, and carefully chosen so they are plump and likely to yield a big flower. Becky Heath, one of the proprietors of the Virginia mail-order company Brent and Becky’s Bulbs, noted that after that first flowering, the mother bulb splits into smaller bulbs as a mechanism of reproduction. The energy required to produce a large blossom the following year cannot be stored in those bulblets.
However, certain tulip varieties do a better job at developing robust offspring. Furthermore, all tulips thrive more successfully when planted in the right location and given the right care.
Fosteriana and the original Darwin tulips were crossed to create the giant Darwin hybrid tulips, which are noted for their consistency. They are really frequently advertised as perennial tulips.
According to Heath, their bulbs don’t break up as easily, which enables them to make a powerful comeback.
“They resemble something of a tulip powerhouse. Simply put, they have extraordinarily robust genetics “according to Jo-Anne van den Berg-Ohms of Connecticut-based mail-order merchant John Scheepers Inc. She is Scheepers’ great-niece, who in the 1950s brought enormous Darwin hybrids to America.
Large blossoms on sturdy stems are produced by this kind of tulip. They come in a somewhat large variety of colors, some of them are striped.
Fosteriana tulips, commonly known as Emperor tulips, are another kind that typically thrives, according to Tim Schipper of Colorblends, a Connecticut-based business that distributes tulip bulbs in bulk. According to him, Fosteriana tulips grow well in Northeast Ohio but less so in more temperate regions.
Fosterianas’ ability to become perennials is partially genetic, according to Schipper, but it also has to do with the early bloom time. Fosteriana tulips have a lengthy growing season that provides them plenty of time to refuel their energy reserves for the following year, assuming the weather is agreeable, he said.
They have big, elongated flowers and are a little shorter than Darwin hybrids.
Planting species tulips, also known as botanical tulips, is another way to get tulips to come back. They resemble their natural progenitors more than the large tulips that have been created through hybridization because they are smaller, more delicate plants.
Tulip species reproduce and form clusters that get bigger every year, a process known as “naturalizing,” in addition to coming back every year. According to van den Berg-Ohms, that process begins when bulblets produced by the mother bulb become large enough to separate off and develop their own flowers.
Species tulips can grow anywhere from 5 to 12 inches tall, depending on the variety. Tulipa biflora, a little white flower with a yellow center, and T. praestans fuselier, a multiflowering tulip with a vivid orange-red color, are just a couple of examples of the species.
According to Schipper, these little plants offer a subtle burst of color rather than a dramatic display. They do best in areas where they will receive enough sunlight, such as rock gardens, walkway margins, and tree drip lines.
Schipper believes that altering one’s perspective is one of the most crucial elements in perennializing tulips. You must think about where the tulips have the highest chance of long-term survival rather than following where you want them to grow.
Tulips prefer soil with a pH of 7, good drainage, and at least six hours of sunlight each day. The more closely you can mimic their original mountainous regions in central Asia, when winters are bitterly cold and summers are dry, the better your chances will be, according to Schipper.
Well-drained soil, according to Heath, is crucial in the summer. The bulbs are then inactive, and she claimed that “much like me, they want to sleep in a dry bed.”
Schipper advised against planting too early in the year. When asked when the fall leaf color is at its best, he advised waiting until daytime temperatures were in the 70s and nighttime temps were in the 40s.
Tulips can be kept coming back by planting them further into the ground than other types of bulbs. According to van den Berg-Ohms, this gives them better protection from temperature fluctuations and increases their exposure to the minerals and other healthy components of the soil.
Heath advises planting at a depth equal to four times the bulb’s height. She claimed that because of the increased ground pressure at that depth, the bulbs typically resist breaking.
If the fall has been dry, she advised watering the plants right afterwards to help the roots take root.
According to van den Berg-Ohms, tulips don’t require fertilizer when they are planted. In the bulb, they already have everything they require.
However, after the first year, fertilization can increase their strength, according to her. Three times a year, in the fall, early spring when the sprouts first show, and late spring when the blossoms begin to wither, she advises applying an organic fertilizer by way of a light sprinkle. She advised picking a fertilizer with more phosphorus than nitrogen or potassium.
In the summer, when the bulbs are dormant, watch that they don’t get too much moisture. When water-loving annual flowers are planted in the same area after tulips finish flowering, Schipper said there is frequently an issue with excess moisture. Tulip bulbs can perish if they are watered at the same time as annual plants during the summer.
Additionally, Van den Berg-Ohms advised against cutting the bigger varieties of tulips to bring inside. She claimed that cutting off their stems reduces their capacity to store energy. To avoid the plant putting its energy into seed production, wait until the flowers have finished flowering and are beginning to die back before cutting off the flower heads about an inch below the base.
Tulips of the lesser species don’t require deadheading. In fact, Heath said that leaving the flower heads on encourages seed germination, possibly leading to the growth of additional plants.
(You shouldn’t do it with the larger tulips because a seed doesn’t bloom right away. Keeping the energy of the current plant is preferable to trying to create new ones.)
Allow the foliage to wither for up to eight weeks before removing it. Even if it’s not particularly gorgeous at that point, the experts advised against braiding it to make hair look more tidy. So that the plants can use photosynthesis to replenish the bulbs, you should leave as much of the foliage exposed to the sun as you can.
Vole and deer problems? Plantskydd, a repellant produced from dried blood, is advised by Heath.
According to Schipper and van den Berg-Ohms, a warmer spring can shorten the growing season by causing the flower bud to open before the plant reaches its full height. As a result, there is less plant mass left to use photosynthesis to produce food for the following year.
And some locations simply have better circumstances than others. In one area of your yard, tulips might come back every year, but not in another, according to Schipper. People frequently phone him asking to plant the same type of tulips that their grandmothers’ yards used to have in bloom every year, but the microclimate, not the particular variety of tulip, was probably to blame.
The first year’s bloom will be the nicest with the larger tulips, he said. The years after that won’t ever be as remarkable, but “it’s still respectable,” he remarked.
