Tulips (Tulipa spp.) are produced from bulbs that contain all the energy and nutrients needed for the plants to blossom in the spring. In U.S. Department of Agriculture plant hardiness zones 3 through 8, most tulips are perennials, and a few cultivars may withstand zone 9 conditions. When planted and cared for properly, tulip bulbs can begin to bloom within a year after being planted.
How long do tulip bulbs take to bloom?
The lily family is the home of the tulip. The bulb is made up of tightly packed bulb scales that surround a center area that contains developing foliage leaves and flower buds, and it has a tough, papery tunic covering. Texas A&M University Aggie Horticulture explains that the roots grow from a basal plate at the base of these structures.
A marketable bulb takes commercial growers two to three years to create. Every year, flower stalks are cut off so that energy can be put into developing the flower’s embryo for the upcoming selling season. Tulips come in early, medium, and late varieties, thus the cold treatment changes a little bit based on the variety.
According to Purdue University, tulips typically require 8 to 16 weeks of artificial winter. The tulip will sprout and leave swiftly after being placed in spring-like conditions, giving rise to a flowering plant in 15 to 30 days.
Why did my tulips not bloom?
The simple fact that tulips require a highly specific climate in order to bloom each year is the most frequent cause of tulips that leaf out but do not bloom. The mountains, which are frequently dry, have scorching summers and freezing winters are where tulips first appeared. Tulips that are grown in our gardens might not experience this identical environment, and they struggle to develop a flower bud in its absence.
Lack of nutrition is another, less likely, explanation for non-flowering tulips. Phosphorus is required by all flower bulbs, not just tulips, in order to develop flower buds. Your tulips won’t blossom each year if your soil is phosphorus deficient.
Why don’t my tulips bloom despite having leaves?
After putting so much effort into planting bulbs in the fall, it is quite frustrating to discover that they do not bloom the following year. The problem is best solved in the spring when the bulbs should be in bloom and are instead covered in leaves. The most frequent cause of a bulb failing to blossom is shallow planting. The best time to dig out the bulb and replant it at a deeper level is when the plant is in leaf but not in flower. Here are some suggestions to ensure the spring bulbs bloom the following year. Different varieties of bulbs may fail for various causes.
When should the tulip bulbs begin to emerge?
Providing a response to the query, “How long does it take for flower bulbs to grow? may need some explanation. When warm weather arrives, spring bulbs begin to develop and blossom. They can only bloom if they have undergone the necessary freezing period to emerge from hibernation. The best time to plant spring bulb flowers across the majority of the nation is in October. This gives the bulb the 12 to 15 weeks of chilling it needs to sprout in the spring.
For up to 15 weeks, spring bulb flowers require temperatures between 35 and 45 degrees Fahrenheit (1-7 degrees Celsius). Each species has a different blooming period after cooling.
- Tulips must be chilled for 10 to 16 weeks before sprouting one to three weeks later.
- Similar spouting periods are observed in crocus, grape hyacinth, and daffodils, although crocus and grape hyacinth require 8 to 15 weeks of freezing, while daffodils require 12 to 15 weeks.
- Snowdrops require 15 complete weeks of cold weather in order to bloom, which can start two weeks after chilling.
- Hyacinths and iris require 13 to 15 weeks of chilling before sprouting, which happens one to two weeks after the condition has been met.
If lazy gardeners didn’t plant their spring bulb flowers in the fall, they never had to worry. You may either buy pre-chilled bulbs in the spring or chill your own bulbs in your vegetable crisper all winter long. Keep bulbs away from fruit that is about to ripen, such as apples and tomatoes, and give them the required amount of weeks.
- Plant bulbs in a soilless mixture in a pot that is twice as deep as the bulb. Soilless mixtures aid in preventing rot, a frequent issue with container bulbs.
- Try placing bulbs on a layer of glass beads or rocks that is 2 to 3 inches (5-8 cm) thick without any soil. Just enough water should be added to fill the bulb completely.
Within a few weeks of the required chilling periods being met, the bulb should start to sprout.
Tulip bulbs can be left in the ground all year.
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.
Do tulips grow in number?
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.
What to do if the lights don’t work?
Bulbs that bloom require at least six hours of direct sunlight each day. Soil with poor drainage: Although bulbs require regular moisture, they cannot tolerate squishy soil. Dig up a few bulbs to check if they have decayed if you believe this may be the cause of their failure to bloom. Your bulbs might need to be relocated to a better spot.

How to Choose Tulips
Hybrid tulips make up the majority of the tulips you see in landscape plantings, as well as those offered for sale at garden centers and home improvement shops. For the greatest impact, hybrid tulips normally need to be replaced every year. (We’ll cover how to persuade them to return below.) When given the proper growing circumstances, species tulips will return year after year in zones 4 to 7. These have smaller flowers and pointier petals than hybrid tulips, and they are shorter.
Individual tulips don’t flower for very long, especially the hybrids. However, there are types that bloom in the early, mid, and late seasons at various periods. When buying, choose a couple cultivars from each bloom time category for a long-lasting display.
Where to Plant Tulips
For the best show, tulips need full sun, which entails at least six hours every day of bright, direct sunlight. They are also great additions to rock gardens since they favor quick-draining soil.
When to Plant Tulips
Fall is the best time to plant tulip bulbs. Prior to planting, the soil must have cooled from the summer growing season, which could occur in September in cold regions (zones 3 to 5), October in transitional temperatures (zones 6 to 7), and November or December in warm areas (zones 8 to 9). Use a soil thermometer to measure the soil’s temperature, and plant when it reaches 60 degrees F at a depth of 6 inches.
For tulips to bloom, they need to be chilled. Buy pre-cooled bulbs and plant them in December if you intend to grow tulips where the soil temperature won’t fall below 60 degrees for at least 12 weeks.
How to Prepare the Soil for Planting Tulips
Use Miracle-Gro Garden Soil for Flowers to prepare the planting space for tulips by incorporating 3 inches of garden soil into the top 6 to 8 inches of native soil. Tulips will develop a strong root system in the fall thanks to the nutrients provided by the soil, which is necessary for a significant spring bloom. However, to get the best results from your tulips, you must combine the strength of excellent soil with just the appropriate plant food. For details on what and when to feed tulips, see “How to Feed Tulips” below.
How to Plant Tulips
Tulips should be planted in bunches of 10 or more for the best display. The pointed end should be facing up as you plant each bulb 8 inches deep (measure from the bottom of the bulb and add the depth of any mulch on top of the soil in your measurement). It is possible to place bulbs close to one another. Thoroughly water.
How to Grow Tulips in a Pot
Tulips are easy to grow in pots. The bulbs should be buried at least 8 inches deep, much like with in-ground plantings, so measure from the top of the container to a depth of about 9 inches, then fill the pot up to that point with Miracle-Gro Potting Mix. Put the pointy end of the bulbs in the pot (you can pack them tightly together). After thoroughly watering, cover with the potting mix. Move the container to a cool, dry spot that stays at or below 40 degrees Fahrenheit during the winter before the first frost in your area. Bring the container outside to a sunny area when you notice tulips budding. Water the soil there. Once you notice green growth, start watering often.
How to Water Tulips
When you plant tulips, make sure to thoroughly water each planting space. After planting, give the plants one watering each week for the first month. Then, leave them alone until spring. When the leaves come out in the spring, start watering once more.
How to Feed Tulips
Apply Miracle-Gro Shake ‘n Feed Rose & Bloom Plant Food in accordance with the instructions on the package once the flowers have faded. In order for the bulb to conserve nutrients for the following growing season, this will aid in promoting leaf growth. Every year in the late fall, feed for the final time (around the same time as you would plant new bulbs).
How to Cut Tulips to Enjoy Indoors
When the buds are still tightly closed, cut tulips. You should be able to identify the hue of the blooms despite the petals’ possible greenish tint. Put inside a spotless vase with room temperature water. Once cut and brought indoors, tulips will continue to “grow” (the stems extend). Simply trim a few inches from the bottom of the stems every few days if they start to get unruly. If you mix Miracle-Gro for Fresh Cut Flowers into the water and replace the water every few days, cut tulips will stay longer (compared to water only).
What to Do After Tulips Bloom
The best tulip flower display will typically occur in gardens in the spring that immediately follows the fall when the bulbs are planted. Once the petals have faded, trim the flower stalk back to the plant’s base to encourage species tulips to return year after year. After the bulbs have gone dormant, cease feeding them as previously mentioned, stop watering them, and trim back the foliage once it has completely turned brown. Simply pluck up the bulbs from hybrid varieties (which are not perennial) and compost them.
How to Protect Tulips from Deer and Other Pests
Preventing deer from eating tulip blooms is the biggest obstacle in tulip gardening, closely followed by preventing chipmunks and squirrels from digging up the bulbs. Planting holes or trenches should have chicken wire surrounding them on all sides to prevent bulbs from being dug up. (If you’re planting large sweeps of bulbs, which is how to get the best show from tulips, this is most useful.)
Deer are another matter. Installing a long (8 feet or more) fence is the greatest approach to keep deer out of the garden, but most people cannot afford to do this. Daffodil and Crown Imperial bulbs are not consumed by deer, so interplanting tulips with these varieties may help deter them. Alternatively, you may try misting a deer repellent on bulb foliage. In light of this, it is preferable to grow tulips in pots on a screened-in porch if deer are a significant issue where you live. This way, the deer can’t access to the flowers.
