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.
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).
What is the recommended depth and spacing between tulip bulbs?
Typically, tulips are planted 3 to 6 inches apart and 6 inches deep. Tulips should be planted 8 inches deep in places with frequent frost. They are also protected from animal predation by doing this. Always water bulbs after planting, and in hot, dry areas, keep watering. Rainfall alone should be sufficient to water tulips in rainy areas because they don’t fare well in settings where there is too much standing water and could rot. Tulip bulbs should be fertilized with a 4-4-2 organic bulb fertilizer both after planting in the fall and again in the early spring when sprouts start to appear. Put a few inches of mulch on top of your bulb bed to keep it warm and maintain a consistent level of soil moisture.
Before removing stems and leaves, let them naturally wither and turn yellow or brown. The bulb won’t be able to store enough nutrients to bloom the following year if the leaves are removed while they are still green.
Give tulips plenty of space for air circulation around the plants to limit fungal growth in order to prevent pests and illness. Do not plant there for at least three years if your planting location has been contaminated. Before purchase, check bulbs for symptoms of decay, and get rid of sick plants right away. Aphids, bulb mites, thrips, rats, and deer can all cause damage to tulips. Chicken wire can be used to protect plants from being eaten. Keep an eye out for pests and get rid of them swiftly to save the remaining plants.
What should the bulb spacing be?
Historically, flower bulbs have been associated with mysticism. The passage of time changes these ordinary objects into extraordinary displays of beauty from their initial rough and unclean state. We thought we’d address the most frequently asked questions about bulbs here because we get a lot of them.
The optimal time to plant spring flowering bulbs is in the fall. That refers to the months of September through November in Maine. However, if the soil or compost is manageable to cultivate, bulbs can still be planted after the first signs of winter frost.
There are various ways to plant flower bulbs, but the simplest is to just use a trowel to make a shallow hole. Gently disperse the bulbs across the planned planting area, letting them fall into any holes they “find,” to provide a more “natural” impression.
Depending on the size of the bulb you’re planting, you should plant it twice as deep as it is tall.
Larger bulbs should be planted with a distance of about five inches between them, while smaller bulbs should be put around four inches apart. You can plant them further closely, so that the bulbs are almost touching, to provide a bolder flash of color.
When grown naturally in well-drained soil, flower bulbs flourish. They also prefer some compost or organic material added to the planting soil. However, it’s crucial to keep in mind that you should constantly cultivate your garden soil before planting anything. It not only makes planting much simpler, but it also promotes a strong start for the bulbs’ new roots. As long as the pots are filled with compost or free-draining soil, bulbs can also be planted in them. They won’t require additional plant food during their first growth season if they are put in a container.
After planting your bulbs, thoroughly moisten the ground. Cover them with straw, fallen leaves, or compost if you live in a location that experiences severe frosts to provide them with additional protection.
Plants marked with a number sign (#) and a number are generally the same size as gallon pots; for example, #2 is equivalent to a 2 gallon pot, #3 to a 3 gallon pot, and so on. These plants are offered for sale in pots.
Plants with a height (such as 5-6′) give an estimate of the plant’s present height.
Plants that are measured in inches (such as 2.5″) are identified by their caliper, or trunk width.
Plants are typically larger when measured by caliper (inches) than when assessed by height (feet).
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.
