Introduction
There is nothing quite like the first sight of tulips opening in the spring sun. These vibrant flowers are a symbol of a fresh start in the garden, bringing cheer to beds, borders, and walkways. At Longfield Gardens, we want you to enjoy that beauty every single year. While the blooming period is the main event, what you do after the flowers fade is the secret to keeping your garden healthy and vibrant.
Taking care of your tulip bulbs after they bloom involves a few simple steps to help the plant store energy for the future. Whether you want to try and get your tulips to flower again next year or you treat them as seasonal annuals, the process is straightforward and rewarding. This guide will walk you through exactly how to handle your tulips from the moment the petals fall until the bulbs go dormant for the summer.
Success in the garden is often about following a few basic rules of nature. By understanding what the bulb needs during its "recharging" phase, you can make the best choices for your outdoor space. If you’re planning ahead, it also helps to check your hardiness zone so you know what to expect in your climate.
The Post-Bloom Lifecycle of a Tulip
To understand how to take care of tulip bulbs after blooming, it helps to know what is happening underground. A tulip bulb is essentially a concentrated storage unit. It holds all the energy, nutrients, and even the "blueprint" for next year's flower inside its papery skin.
When the flower is in full bloom, the bulb is at its weakest because it has spent most of its stored energy. Once the bloom fades, the plant enters a critical phase. It needs to "refill the tank" by pulling energy from the sun through its leaves and moving it down into the bulb. This process takes several weeks.
During this time, the plant isn't just sitting there; it is hard at work. The roots are still pulling moisture and minerals from the soil, and the green leaves are performing photosynthesis. If you interrupt this process too early, the bulb may not have enough strength to produce a flower the following spring. For more on timing, see our shipping information.
Step 1: Deadheading the Spent Flowers
The very first task after your tulips finish blooming is called deadheading. This simply means removing the faded flower head from the stem. You should do this as soon as the petals begin to wilt or drop.
When a tulip flower is left on the plant, it eventually turns into a seed pod. Creating seeds takes a significant amount of energy. By snipping off the flower head, you tell the plant to stop focusing on reproduction and start focusing on the bulb.
To deadhead correctly, follow these steps:
- Use a clean pair of garden snips or sharp scissors.
- Cut the flower head off at the top of the stem.
- Leave the rest of the green flower stem and all the leaves attached to the plant.
- Do not pull the stem out of the ground, as this could damage the bulb.
Key Takeaway: Deadheading prevents the plant from wasting energy on seed production. This keeps the energy where you want it: inside the bulb for next season.
Step 2: Caring for the Foliage
The most important rule of tulip aftercare is to leave the leaves alone. It can be tempting to trim away the green foliage once the flowers are gone, especially if you prefer a tidy-looking garden. However, those leaves are the only way the bulb can feed itself.
The leaves must remain on the plant until they have turned completely yellow or brown and have started to wither. This usually takes about six to eight weeks after the flowering has finished. During this time, the plant is absorbing sunlight and converting it into the carbohydrates needed for the bulb to survive the winter.
How to Manage "Messy" Foliage
If the fading leaves bother you, there are a few simple ways to hide them without harming the bulb:
- Interplant with Perennials: Plant your tulips near late-emerging perennials like hostas, daylilies, or ferns. As the tulip leaves fade, the perennials grow larger and naturally cover the yellowing foliage.
- Add Annuals: Plant colorful annuals around the tulip base. These will draw the eye upward and mask the drying leaves near the ground.
- Do Not Braid or Tie: Some older gardening advice suggests braiding or tying the leaves together. Avoid this, as it reduces the surface area available for sunlight and can trap moisture, leading to rot.
Step 3: Watering and Fertilizing Post-Bloom
Even though the flowers are gone, the plant is still active. If your spring is particularly dry, your tulips will benefit from occasional watering. You want the soil to stay moist but never soggy.
Good drainage is essential for tulips. If the soil stays too wet after the blooming period, the bulbs can rot while they are trying to go dormant. If you have sandy soil, you may need to water more often. If you have heavy clay soil, be very careful not to overwater.
Should You Fertilize?
Most of the time, tulips do not need heavy feeding after they bloom. If you have very poor soil, you can apply a balanced, slow-release fertilizer or a thin layer of compost when the first green shoots appear in early spring. Avoid fertilizing once the plant has finished blooming, as this can sometimes encourage fungal issues or late-season growth that the bulb cannot support.
Step 4: Lifting vs. Leaving the Bulbs
Once the foliage has completely died back and turned brittle, you have a choice to make. You can either leave the bulbs in the ground or "lift" them to store for the summer.
Leaving Bulbs in the Ground
In many parts of the United States, tulips are treated as annuals. This is because many modern tulip varieties are bred for one spectacular show of color. Over time, these highly bred varieties tend to get smaller and eventually stop blooming.
If you live in a climate with cold winters and very dry, hot summers, your tulips have a better chance of returning. Tulips prefer to be kept bone-dry during their summer dormancy. If your garden beds are heavily irrigated during the summer for other plants, the tulip bulbs may rot or split into tiny "bulblets" that are too small to flower.
Lifting the Bulbs
If you want to save your bulbs but need the space for summer planting, or if your soil stays too wet in the summer, you can lift them. This means digging them up and storing them in a controlled environment.
- Wait for the Foliage to Die: Only lift the bulbs once the leaves are brown and pull away from the bulb easily.
- Dig Carefully: Use a garden fork to gently loosen the soil around the bulbs. Be careful not to nick or cut the bulbs.
- Clean the Bulbs: Gently brush off the excess soil. Do not wash them with water, as moisture is the enemy during storage.
- Inspect for Damage: Only keep bulbs that are firm and heavy. Discard any that feel soft, mushy, or look moldy.
How to Store Tulip Bulbs for Summer
If you have decided to lift your bulbs, proper storage is the key to keeping them healthy until fall planting. At Longfield Gardens, we recommend keeping bulbs in a spot that mimics their natural environment: dry, dark, and with plenty of air circulation.
Find a location like a garage, a shed, or a cool basement. The temperature should be consistent and not overly humid. Avoid storing bulbs in plastic bags, as these trap moisture and cause rot.
- Use Mesh Bags: Old onion bags or mesh laundry bags are perfect for storage because they allow air to flow around every side of the bulb.
- Use Cardboard Boxes: If you use a box, line it with a bit of dry newspaper and place the bulbs in a single layer. Do not stack them deep.
- Avoid Fruit Storage: Never store bulbs in a refrigerator near ripening fruit (especially apples). Fruit gives off ethylene gas, which can kill the flower bud inside the bulb.
Check on your stored bulbs once a month. If you find any that have become soft or show signs of blue mold, remove them immediately so the issue doesn't spread to the healthy bulbs.
What to Do Next:
- Mark your calendar for 6-8 weeks after blooming to check foliage.
- Prepare a dry, dark storage area if you plan to lift your bulbs.
- Clear away any dead debris from the garden bed once the leaves are brittle.
Choosing Varieties That Come Back
If your goal is to have tulips that return year after year without a lot of extra work, the variety you choose makes a huge difference. While some tulips are best used as a one-time splash of color, others are more "perennial" in nature.
Darwin Hybrid Tulips are famous for their ability to return for several seasons. They have large, classic flower shapes and strong stems. Because they are more vigorous, they handle the stress of the "off-season" better than many other types.
Emperor Tulips (Fosteriana) are another excellent choice for longevity. They bloom early and have a natural tendency to come back if they are planted in a sunny, well-drained spot.
Species Tulips are the closest to the original wild tulips. These are typically smaller and more delicate-looking, but they are incredibly hardy. They often "naturalize," meaning they will not only come back but will also spread and multiply over time.
When you shop with us, look for varieties specifically noted for their ability to return. Matching the right plant to your specific garden conditions—sun, soil, and drainage—is the easiest way to ensure long-term success.
Caring for Tulips in Containers
Tulips planted in pots and containers require a slightly different approach after blooming. Because the environment in a pot is much more confined than the ground, the bulbs face more stress.
In a container, the soil can heat up quickly and dry out faster. Conversely, if the pot doesn't have excellent drainage, the bulbs will sit in water and rot. Most gardeners find that container-grown tulips are best treated as annuals. Once the flowers fade, you can compost the bulbs and the soil and use the container for summer annuals.
If you are determined to save bulbs from a container, you should transplant them into the ground as soon as the flowers fade. Dig a hole in a sunny spot and move the entire "root ball" from the pot into the soil. Let the foliage die back naturally in the ground. This gives the bulb a much better chance of recovering than staying in a small pot. For other plants that suit this style, see our perennial plants for containers.
Common Questions About Post-Bloom Care
One of the most frequent questions we hear is whether you can move tulips while they are still green. The answer is yes, but you must be very gentle. This is often called moving tulips "in the green." If you need to move them to a different part of the yard, dig up the entire clump with as much soil as possible and replant them immediately at the same depth. Water them well so the roots don't dry out.
Another common concern is "blind" tulips—bulbs that produce leaves but no flowers. This usually happens if the bulb didn't store enough energy the previous year. This could be due to cutting the leaves too early, or the bulb simply being too old. In this case, it is usually best to start fresh with new, high-quality bulbs in the fall.
Finally, keep an eye out for pests. Once the tulips have finished blooming, rodents like squirrels or voles might try to dig up the bulbs. If you have had trouble with this in the past, you can lay a piece of hardware cloth (wire mesh) over the planting area once the foliage is gone to protect the bulbs through the summer.
Preparing for Fall Planting
Taking care of tulips after they bloom is actually the first step in preparing for next year’s garden. Even if you decide to treat your tulips as annuals and pull them up once the flowers fade, the "aftercare" period is a great time to evaluate your garden.
Take photos of your garden while the tulips are in bloom. This helps you remember where you want more color next year. You might realize you want a different color palette or that you need more mid-season varieties to bridge the gap between early and late bloomers. If you want help choosing combinations, browse our perennial plants by color.
If you are lifting and storing bulbs, keep them labeled clearly. It is very easy to forget which bulb is which once they are just brown, papery shells in a mesh bag. Write the variety name and color on a tag and attach it to the storage container.
Conclusion
Taking care of tulip bulbs after they bloom is one of the simplest ways to participate in the natural cycle of your garden. By deadheading the spent flowers and allowing the foliage to wither naturally, you give the bulbs the best possible chance to return with vigor. Whether you leave them in the ground to naturalize or lift them for storage, the goal is always the same: protecting that stored energy for a future display of color.

FAQ
Should I cut the stems off tulips after they bloom?
You should cut off the flower head and the very top of the stem once the petals fall. However, you must leave the rest of the green stem and all the leaves attached to the plant. These green parts are necessary for the bulb to create energy for next year’s flowers.
Why are my tulips coming up but not blooming?
This is often referred to as "blind" growth. It usually happens if the foliage was cut back too early the previous year, preventing the bulb from storing enough energy. Other causes include the bulbs being too old, overcrowded, or the soil being too wet during the summer, which can cause the flower bud inside the bulb to rot.
Can I leave tulip bulbs in the ground all year?
Yes, you can leave them in the ground, provided the soil has excellent drainage. In areas with wet, rainy summers, the bulbs are more likely to rot or split, so many gardeners prefer to dig them up and store them. If you leave them, avoid overwatering the area during the summer months. For more details on timing, check our shipping information.
When is the best time to dig up tulip bulbs to store them?
Wait until the foliage has turned completely brown and is dry enough to pull away from the bulb with a gentle tug. This usually occurs 6 to 8 weeks after the flowers have finished blooming. Digging them up earlier will result in weak bulbs that may not flower the following year.
