Planting Spring Bulbs: What Are Bulbs For Spring Season


By: Susan Patterson, Master Gardener

There is nothing more satisfying to a gardener than seeing those first early spring flower bulbs popping up from the cold ground. These little sprouts soon bloom into gorgeous blossoms, brightening up your garden for the start of a great growing year. Let’s take a look at some common types of spring flowering bulbs.

Flower Gardening with Spring Bulbs

There are many types of spring flowering bulbs to choose from. Most people select some of each kind for a brilliant spring display.

Tulip – These happy spring flowers are probably one of the more well-known spring bulbs. There are many variations and tons of colors to choose from. These bulbs prefer well drained or sandy soil that is rich in fertilizer.

Plant tulips in the fall for spring blooms. Planting these spring bulbs is fairly easy. Place bulbs 4 to 8 inches deep and about 6 inches apart. In some areas, plants will come back year after year. In other areas, they will need to be replanted.

Siberian Squill – These pretty deep blue flowers bloom on straight grass-like leaves and stems. They need to be planted in the fall for early spring blooms. They like well-drained soil in a sunny or partially sunny area. Plants can grow around 6 inches high and need to be planted around 6 inches apart and 4 inches deep.

Daffodil – Daffodils are another spring favorite among gardeners with their beautiful yellow and white flowers. They like to grow in well-drained soil but it needs to be rich in compost or other organic matter.

Daffodils do well in an area with full or partial sun. Their leaves are shiny, long stalks, and the flowers look like little cups. They should be planted 6 to 12 inches deep and 6 to 12 inches apart. Larger varieties will need more room. Divide every three or four years to keep these spring beauties from taking over.

Dutch Iris – The Dutch iris is a beautiful dark purple iris variety that is a perfect cut flower. It can grow up to 2 feet high and needs to be divided after a few years to keep it under control. This kind of iris likes dry and sunny spots where it will receive full sun all day. Plant bulbs in the fall 5 inches deep and 6 inches apart.

Common Snowdrop – These dainty little white flowers look like something straight out of a fairy tale. The blooms hang down in a dropping fashion. These bulbs do well in full or partial shade and moist soil. Plenty of compost is a must for beautiful blooms. Plant in the fall about 3 inches deep, and 3 inches apart.

Crocus – These cute flowers are low to the ground and are perfect for garden borders. They grow about 6 inches high and bloom white, yellow, purple, or striped. They prefer well drained soil in partial shade or full sun. Plant in the fall for early spring blooms. Bulbs should be 3 inches deep and 4 inches apart.

How to Care for Spring Flower Bulbs After They Bloom

Spring flower bulbs get the gardening season off to an early start. From the first crocuses and daffodils to the last tulips and alliums, it’s a show that can last from March through May.

When spring eventually turns to summer, gardeners often wonder what to do about the spent flowers and fading foliage from their spring-blooming bulbs. The answer is, it depends if you’re treating the bulbs as annuals or perennials.

Spring Bulbs as Annuals

Many spring-blooming bulbs, including crocuses, daffodils, chionodoxa and scilla, return to bloom year after year. But not all bulbs behave this way. Tulips, for example, always look their best the first year after planting. If the soil and climate conditions are ideal, they may re-bloom for several years. But in most cases, after that first year, the bulbs will go on to produce smaller flowers and fewer of them.

For this reason, we usually recommend treating tulips as annuals. After they finish blooming, use a garden fork to gently lift the bulbs out of the ground and put the entire plant in your compost pile. Removing the bulbs as well as the foliage will help minimize problems with fusarium, a common fungal disease that can affect tulips.

Replanting fresh bulbs every fall may sound extravagant, but there are advantages. You can count on always getting a fabulous display of spring flowers. You also get the fun of creating completely new combinations of colors and textures each and every year.

Spring Bulbs as Perennials

Early-blooming bulbs such as snowdrops, crocus, chionodoxa, scilla and most daffodils are reliably perennial. If the growing conditions are agreeable, they will rebloom every spring and most will also multiply over time. There’s no need to deadhead, fertilize or divide them unless they become overcrowded or you want to spread them around in other areas.

Hyacinths will usually bloom for several years, though the size of the flowers tends to gradually decline. Muscari, fritillaria and alliums will also return to bloom again if the soil is well-drained and stays relatively dry during summer and winter.

Most spring-blooming bulbs grow best in loose, well-drained soil that is warm and relatively dry in the summer and cold and relatively dry in the winter.

Tulips are the fussiest about soil conditions. When they are planted in heavy soil that holds too much moisture, the bulbs have a tendency to split. If you have ever dug up a tulip bulb after it has bloomed, you may have seen this yourself.

Once a tulip bulb has split into two or more sections, it no longer has enough energy to produce a full-size blossom. Some types of tulips are less prone to splitting and more likely to rebloom. These include most species tulips, Darwin hybrids, emperor tulips and some triumph tulips.

Removing Spent Flowers

If you want to try getting your tulips to re-bloom, snip off the flowers right after they fade. With daffodils, there’s really no reason to remove the spent flowers — other than to make them look better.

The seed heads of alliums can be almost as attractive as the flowers, so you may want to leave them in place. Removing them doesn’t seem to affect the performance of the bulbs one way or another. Do be aware that some alliums, including Purple Sensation, will self-sow. If you don’t want seedlings, you need to remove the flower heads.

Smaller bulbs, such as crocus, muscari, scilla and snowdrops, multiply by seed as well as by bulb offsets. To encourage naturalizing, it’s best to leave those flowers attached so the seeds can ripen.

Hiding or Removing Bulb Foliage

Bulbs use their foliage to produce the energy they need to form new flowers. So, if you want your bulbs to re-bloom, it’s important to leave the foliage in place until it has withered and turned yellow. When the foliage can be pulled away from the bulb with a gentle tug, it’s ready to go.

The foliage of early-blooming bulbs such as chionodoxa and scilla fades away in a matter of weeks. Larger bulbs can take as long as a few months, depending on the weather and type of bulb. There are several ways you can cope with this ripening foliage.

In a perennial garden, you can use the foliage of other plants hide the leaves. Hostas, daylilies, nepeta and perennial geraniums do an excellent job of covering the spent foliage of tulips, daffodils and alliums.

Another option is to plant your bulbs in an area where you won’t mind seeing the foliage. Alliums and daffodils are ideal for meadows, road sides and other wild-ish areas where their ripening foliage will be out of sight.

Consider planting some of your tulips and hyacinths in a cutting garden or part of your vegetable garden — rather than among your perennials. They will appreciate the good soil and lack of competition. After they bloom, it takes no time at all to dig them out before planting warm-weather crops such as dahlias or tomatoes.

One other option is to dig up your spring bulbs immediately after they have finished flowering and replant them – with foliage still attached – in a holding bed. When fall comes, dig up the bulbs and move them back.

The information on your site is so helpful to me, someone who continues to learn about plants and the reasons for a dull or not so prolific perennial garden. I appreciate the time it takes someone to place all the information on this site and I will continue to purchase your products through Costco and or your website. Thank you so much.

Hi Phyllis – how thoughtful of you to leave this comment. Thank you! Learning to garden is a lifelong adventure. Though there’s no substitute for hands-on experience, we are eager to share what we know and hope it helps you have more fun and success.

I dig up most of my bulbs when spring is over. Put in container so air can get to them and use again next year. I keep bulbs in a cold frame.


  1. Established bulb plantings will emerge earlier than bulbs that were planted this past fall.
  2. Bulbs like tulips and crocus open up their blooms in the sun and close in overcast and nighttime skies.
  3. If your bulbs like tulips are emerging and the temps get cold, or snow happens no need to cover them. Nature will take care of the bulbs with no damage to the emerging flowers.
  4. Protect your garden from hungry deer and rabbits by applying Liquid Fence to vulnerable areas. Re-apply after rain or snow.
  5. Most bulbs and some perennials go dormant after blooming. Plan for the void they will leave in by planting summer blooming perennials and bulbs.
  6. Peonies live for many decades, often 75+ years. They like to remain in the same location and don’t tolerate transplanting well.

Spring is here and flowers bring lots of cheer! The tips above will help your garden grow and increase your garden smarts. If you learned something from these tips share them with friends and family.
