The process of raising tulips is simple. Every bulb contains a lovely flower that is just waiting to bloom. Continue reading to find out how to start your tulips off right.
Good Soil Yields Better Results
Tulips grow best in crumbly, loose soil that is simple to cultivate and is very well drained. Critical is the well-drained portion. Too-wet soil might cause bulbs to decay. Tulips are planted in sand in Holland, ensuring that they are never in a damp environment.
Plant Like a Pro
Tulips look their best when planted in bunches of 50 or more bulbs, according to landscape architects. Per square foot, expect 9 to 12 lights. Give the bulbs a 2 to 3 inch gap between them for a complete look. The bulbs will be stretched if they are spaced at 4″, but they won’t appear as full.
Dig out the entire planting area to a depth of 6 to 8 inches, then quickly pile the soil on a tarp nearby to plant a lot of bulbs. After placing the bulbs in the hole, cover them with soil by sliding it off the tarp.
Stretch the Season with Different Types of Tulips
Some varieties of tulips open soon after the crocuses, while others do so before the peonies. Tulips can bloom for six weeks if you select types with various bloom times. Read: Tulips by Bloom Time to find out which varieties bloom when.
Give Them a Sunny Spot
Plant the bulbs in broad sun if at all possible. Your tulips will be able to grow to their fullest height and size as a result. Additionally, tulips thrive in partial shade and under deciduous trees. If the flowers are protected from the sweltering afternoon sun in hotter climates, they will live longer.
Switch Up the Planting Locations
Fungal diseases can affect tulip bulbs, especially if they are grown in a chilly, humid environment. After they have finished blooming, remove the old bulbs and plant new ones each fall to help reduce issues. Rotate planting sites if you can, giving the earth a 3-year break in between.
Plant Tulips Later Than Most Other Fall Bulbs
You should put off planting your tulip bulbs until November for two reasons. Because fungal growth is inhibited by cold temperatures, your bulbs will be less prone to illness. Planting later also allows you to escape the peak hoarding season for squirrels and chipmunks, which can cause difficulties with your bulbs being stolen.
Be Realistic About Second Year Flowers
Every year, the first spring after planting, tulips look their finest. Some tulips can bloom for more than a year if the soil and growing environment are perfect. However, you’ll typically just receive a few little blossoms or sometimes none at all. Simply remove the bulbs once they have finished blooming and plant new ones each fall for the greatest results.
Can you fit how many tulips in a single hole?
When planting tulip bulbs, it is advisable to avoid crowding the holes you dig with more than one bulb per hole. The bulbs should ideally be placed 4 to 6 inches apart, according to The Old Farmer’s Almanac, so it’s critical to choose a location with lots of space. Additionally, you should plant your tulip bulbs deeply—at least 8 inches deep. For best results, measure from the bulb’s base.
Additionally, it’s a good idea to loosen the soil 12 to 15 inches deep with a garden fork or tiller before planting, keeping in mind the appropriate depth at which to place the tulip bulbs. Tulip bulbs should always be planted with the tip side facing upward. Larger bulbs will therefore require larger holes. Plant them, then cover them with earth, pressing down afterward. After planting, water right away to encourage development.
Can tulip bulbs be planted on top of one another?
Is it possible to grow another flower on top of my dormant tulips? The front of my house’s garden has some unsightly gaps in it. Thanks,
Thanita from Ashburn, Virginia
Mike: The reasons we Americans (as opposed to those in Holland) have trouble getting our spring bulbs to bloom year after year are, according to what I overheard you mention last spring:
- We drastically over-earnest the green, nourishing portion of the bulb and
- If we grow annual flowers on top of our bulbs, they receive an excessive amount of watering and fertilizing.
Your recommendation was to dig up the bulbs once the greenery had withered back and layer them in a pot, according to kind, with alternating layers of peat and vermiculite to keep the layers apart. You suggested, I believe, that they should still be watered, just not more frequently than a typical rainfall schedule would allow. So I took action. However, when I went looking for confirmation on the Internet, the data I discovered suggested that it would just cause the bulbs to rot and serve as a buffet for neighborhood field mice and/or squirrels (and deer if they found the container). I gave the collection one “watering”; after that, they only received rain. How did I do?
Hockessin, Delaware’s Tina
A. Tina, you mainly got it correct. The irrigation section was the one you misheard the most. I HOPE I mentioned to only let the rain hit the container they are in and NOT to add ANY water.
However, let’s go back to the beginning. One of the best interview guests we’ve ever had on the program, British gardening writer Anna Pavord, gave us this piece of advise while she was on tour in 2000 in support of her stunning book “The Tulip,” which was published in 1999. I remarked during the interview that one of our most frequent inquiries was over the reliability of tulip returns. That’s because you Americans plant annual flowers on top of the bulbs and then water and Miracle-Grow the crap out of them, rotting the poor bulbs underground, she immediately said.
She explained that Spring bulbs have evolved to live in their native mountains of Russia, Turkey, and Afghanistan in a harsh and largely God-forsaken environment. The bulbs that have been hiding put up their shoots, flower, and absorb a lot of solar energy when heavy snow and freezing cold eventually give way to a rather comfortable Spring. After that, the above-ground growth fades away, and the bulbs hide once more, this time from a dry, sweltering summer.
Therefore, according to Pavord, their DNA does not understand the moisture and food of summer; instead, it understands scorching, dry, and desolate. They don’t respond well to beds that are watered and nourished throughout the summer to keep marigolds, begonias, or petunias alive for that reason.
She continued by saying that because she, too, had a small garden and didn’t want to leave her bulb beds vacant for the summer, she had to learn this lesson the hard way. She began lifting the bulbs, preserving them for the summer, and replanting them in the fall as soon as she realized what was happening. She assured me and my audience that it functioned admirably and had a good deal of room for mistake.
It worked the first time I attempted it that summer and every summer after. I never repeated it exactly the same manner. The first year, when the greens on the bulbs had faded, I pulled them out and moved them to the back of the garden, out of sight and away from the sprinkler. I hammered together a bottomless box out of scrap wood, filled it halfway with soil, then added a layer of one type of bulb, more soil, more bulbs, etc., until it was completely full. Only when it rained did it get irrigated. And I covered it with a tarp when we experienced protracted rainy spells. I removed them in the middle of October, planted them again around Halloween, and had fantastic results.
After a few years, the box completely rotted away, so I transferred to large pots that were initially just plain ugly and had never gotten any prettier. This also functions well. If I have it, I will occasionally add a considerable amount of peat, vermiculite, perlite, or a fine, light professional potting soil blend; if not, I will simply use my compost-enriched garden soil. I’ve never lost more than a few items to rot due to mice or squirrels invading, either (and they were probably already damaged by my tender digging-up style, which involves a lot of creative swearing). Although I adore the picture of Bambi digging through several inches of soil in search of hidden riches, I don’t believe that even deer are that stupid.
Here is how I intend to make my Spring bulbs bloom again:
- Remove the faded blooms and any developing seedpods when they have finished blooming.
- Feed the plants so they will grow new flowers for you the following year. There are numerous feeding instructions in our earlier Spring bulb Question of the Week.
- Wait until the greens have totally lost their green hue before touching them.
- Remove the bulbs. The ideal method is to slowly coax the bulb out of the ground after it goes tan or brown while gently pulling on the faded greens. Go digging if it breaks off, but exercise caution.
- The degreened bulbs should be kept outside in a container with excellent drainage, either in the sun or the shade, in soil, soilless mix, or a mixture of both. Do not water them, and if it is raining a lot, cover the container.
- In the autumn, replant. In the far north, that would be September; in the mid-Atlantic, October; and in warm climates, after Thanksgiving.
How much room are tulip bulbs required for?
See the RHS Guide to Rock Garden Plants if you’d like to grow different varieties of alpine plants. Another excellent method to learn more about growing these plants is to join the Alpine Garden Society.
How to plant tulips
The same method is used to plant both border and specialty tulips, whether they are planted in the ground or in containers. Bulbs should be placed at a depth that is two to three times their height and at least twice their width apart. The bulb’s pointed end ought to be on top.
Tulips thrive in locations with harsh winters because deeper planting shields plants from piercing frosts. Tulips look more natural when planted in clusters of odd numbers, unless they are cultivated for bedding schemes.
Skin sensitivities could result from handling tulip bulbs. If you are impacted by these, wear gloves. If consumed, the plant can upset your stomach in all of its parts.
Planting in the ground
Before planting in the fall, amend your garden soil by tilling in organic material like leaf mold, compost, or well-rotted manure. Apply a general-purpose fertilizer in the spring as the leaves begin to emerge to encourage healthy development, such as Growmore or blood, fish, and bone.
Alkaline or neutral soil is preferred by tulips. Apply lime to your soil to raise pH if it has a pH that is on the acidic side (below pH 6).
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.
