Introduction
There is nothing quite like the first sight of tulips emerging from the soil to signal that spring has truly arrived. These cheerful, cup-shaped flowers bring a sense of joy and vibrant color to the garden after a long winter. While many gardeners enjoy tulips as a one-time spring show, you can actually save those bulbs to enjoy them again. At Longfield Gardens, we want to help you get the most out of your garden by sharing the simple steps to keep your bulbs healthy during their summer nap.
This guide is for anyone who wants to preserve their favorite tulip varieties instead of treating them as annuals. We will cover the best time to lift your bulbs, how to dry them properly, and where to keep them so they stay firm and ready for fall planting. If you’re looking for a reliable place to start, our Darwin Hybrid Tulips are known for strong performance and staying power.
Why You Might Choose to Dig Up Tulip Bulbs
In many parts of the United States, tulips are treated as annuals, meaning they are planted in the fall, bloom in the spring, and then replaced the following year. This is often because tulips are native to regions with very specific climates—typically places with cold winters and hot, bone-dry summers. Our home gardens often have soil that stays too moist or humid during the summer months, which can cause tulip bulbs to struggle if left in the ground.
Lifting your bulbs is a fantastic way to mimic their natural environment. By taking them out of the damp summer earth, you protect them from potential rot and pests. It also gives you the chance to reclaim that garden space for summer annuals or perennials without worrying about accidentally digging into your dormant bulbs later in the season.

Another benefit of digging up your bulbs is the opportunity for inspection. When you lift them, you can see exactly which bulbs are large and healthy and which ones might be too small to produce a flower next year. This ensures that only the highest quality bulbs make it back into your garden in the fall, leading to a more consistent and professional-looking display.
When Is the Best Time to Dig?
Timing is one of the most important factors when learning how to store dug up tulip bulbs. If you dig too early, the bulb won't have enough energy stored to bloom again. If you wait too long, the foliage might disappear entirely, making it difficult to find where the bulbs are buried.
The Role of Foliage
After the flower petals fall off, the tulip plant is still very busy. The green leaves act like solar panels, gathering energy from the sun and sending it down into the bulb. This process, known as photosynthesis, is how the bulb recharges its "batteries" for the following year.
You should leave the leaves alone until they turn yellow or limp and begin to wither. This usually happens about six to eight weeks after the flowers have finished blooming. When the foliage has lost its bright green color and pulls away easily from the ground, the bulb has finished its work and is ready to be lifted.
Monitoring Weather Conditions
It is best to dig up your bulbs on a dry day. Soil that is overly wet can be messy to work with and increases the risk of the bulbs staying damp for too long after they are out of the ground. A clear, breezy day is ideal because the moving air helps the drying process begin immediately.
Key Takeaway: Wait until the foliage is yellow and withered before digging. This ensures the bulb has stored enough energy to produce a flower next spring.
Step-by-Step: How to Dig Up Tulip Bulbs
Lifting bulbs is a gentle process that requires just a little bit of patience. You want to avoid "spearing" the bulbs with your tools, as any cuts or bruises can create an entry point for disease during storage.
Choosing the Right Tools
A spading fork is often better than a solid shovel for this task. The tines of the fork allow soil to fall through while gently lifting the bulbs to the surface. If you only have a small garden bed or a few containers, a hand trowel can also work, provided you are careful.
The Lifting Technique
- Identify the location: Locate the base of the withered tulip stems.
- Give them space: Insert your spading fork into the soil about six inches away from the stem. This "buffer zone" helps you avoid hitting the bulbs directly.
- Loosen the soil: Gently rock the fork back and forth to loosen the earth.
- Lift upward: Lever the fork up to bring the clump of soil and bulbs to the surface.
- Manual extraction: Use your hands to gently pull the bulbs out of the loosened soil.
Once the bulbs are out, give them a light shake to remove large clumps of dirt. Do not scrub them or use water to wash them, as adding moisture at this stage can lead to mold issues later on.
Curing: The Secret to Long-Term Success
"Curing" is simply a fancy word for letting your bulbs dry out completely before they go into long-term storage. This step is non-negotiable if you want your bulbs to survive until autumn. At Longfield Gardens, we maintain a trial garden to observe how different varieties handle the transition from soil to storage, and we have found that proper curing is the single most important step in preventing rot. If you want a broader refresher on post-bloom care, see our How to Store Tulip Bulbs After Blooming guide.
Where to Cure Your Bulbs
Find a spot that is out of direct sunlight but has excellent air circulation. A garage, a covered porch, or a garden shed are all great options. Avoid dark, damp basements for this stage, as you need the air to stay relatively dry.
The Drying Process
Spread the bulbs out in a single layer. You can use a flat cardboard box, a plastic tray, or even a piece of window screen propped up on blocks. The goal is to have air reaching all sides of the bulb. If you leave them in a pile, the ones in the middle will stay damp and may begin to decay.
Let the bulbs sit for about 10 to 14 days. During this time, the outer "tunic" (the papery brown skin) will harden, and any remaining soil will become dry and dusty.
Cleaning and Sorting
After the curing period, you can do a final cleaning.
- Remove the foliage: The dried stems should now snap off easily with your fingers.
- Brush off soil: Use your hands or a soft brush to remove the remaining dry dirt.
- Inspect for health: Gently squeeze each bulb. It should feel firm, like a golf ball. If a bulb feels soft, mushy, or looks shriveled like a raisin, it is best to discard it.
- Look for "offsets": You might notice tiny baby bulbs (bulblets) attached to the main bulb. You can leave these attached or gently snap them off. Keep in mind that very small offsets may take a year or two of growth before they are large enough to flower.
What to do next:
- Move lifted bulbs to a shaded, airy spot immediately.
- Spread them out in a single layer so they don't touch.
- Wait two weeks for the outer skins to harden and dry.
- Discard any bulbs that feel soft or show signs of mold.
Ideal Storage Conditions for Tulip Bulbs
Once your bulbs are clean and dry, they need a safe place to rest until the fall. The goal is to keep them dormant—not too hot, not too cold, and definitely not wet. For a quick refresher on bulb anatomy and health, our What is a Tulip Bulb? guide is a helpful reference.
Temperature and Airflow
The best temperature for storing tulip bulbs is between 60°F and 70°F. This is roughly room temperature. While some bulbs (like paperwhites) enjoy being warmer, and some (like lilies) prefer a refrigerator, tulips are happiest in a cool, dry place like a pantry or a well-ventilated garage.
Airflow remains critical during storage. Never store your bulbs in airtight plastic containers or sealed plastic bags. Moisture will get trapped inside, and your bulbs will likely rot before you ever get the chance to plant them.
Recommended Storage Containers
- Mesh Bags: Old onion or citrus bags are perfect. They allow total airflow and can be hung from a hook to keep them away from rodents.
- Paper Bags: A simple brown paper lunch bag works well. Just keep the top open or poke a few holes in the sides to let the air circulate.
- Cardboard Boxes: Use a shallow box and line it with a bit of dry newspaper or vermiculite. Again, ensure the bulbs are not packed too tightly.
Keeping Pests Away
Squirrels, mice, and chipmunks often find tulip bulbs to be a delicious snack. If you store your bulbs in a garage or shed, consider placing them inside a mesh wire cage or hanging them high enough that small animals cannot reach them.
Planning for Fall Replanting
When the weather begins to cool down and the trees start to change color, it is time to think about getting your stored bulbs back into the ground. In most parts of the US, this happens between September and November, depending on your specific climate. Our How and When to Plant Tulip Bulbs guide covers the basics for getting them back in the soil.
When to Plant
The general rule is to wait until the soil temperature is below 60°F. Planting too early, while the ground is still warm from summer, can encourage the bulbs to start growing foliage instead of roots. You want them to establish strong roots before the ground freezes, but keep their leaves tucked away until spring.
Selecting the Spot
Tulips love the sun. When you bring your stored bulbs back to the garden, choose a location that gets at least six hours of direct sunlight. Ensure the soil is well-draining; if you have heavy clay soil, consider adding some compost or planting in raised beds to help water move away from the bulbs.
Planting Depth and Spacing
For most tulip bulbs, a depth of six to eight inches is ideal. A good rule of thumb is to plant the bulb three times as deep as it is tall. Place the bulbs with the pointy end facing up and the flat, hairy end (the root plate) facing down. Space them about four to six inches apart to give them room to grow without being overcrowded.
Real-World Scenarios and Success Tips
Sometimes, the "perfect" conditions aren't available, but you can still have success. Gardening is all about adapting to your specific environment.
Scenario 1: You live in a very humid climate. If your summers are exceptionally muggy, the curing process is even more vital. You might consider using a small electric fan in the area where your bulbs are drying to keep the air moving constantly. This prevents stagnant, moist air from settling around the bulbs.
Scenario 2: You found a bag of bulbs you forgot to store. If you find bulbs in mid-summer that were left in a bucket or a bag without being cured, check them immediately. If they are still firm, go through the curing and cleaning steps right away. They may still be viable, even if the timing wasn't perfect.
Scenario 3: Your bulbs look a bit "ugly" after storage. It is normal for stored bulbs to look a bit less "pretty" than the ones you buy fresh in a bag. They might have a few spots on the outer skin or look slightly more shriveled. As long as they are firm and do not have active mold or soft spots, they are usually perfectly fine to plant.

FAQ
Can I store tulip bulbs in the refrigerator?
While some bulbs benefit from a "chilling period" in the fridge, it is generally not necessary or recommended for summer storage of tulips. Many refrigerators contain ethylene gas from ripening fruits (like apples), which can damage the flower bud inside the tulip bulb. A cool garage or basement is a much safer choice.
What happens if I forget to dig them up until mid-summer?
If the foliage has already completely disappeared, you can still try to dig them up, but it will be much harder to find them without damaging them. If you can locate them, follow the same curing and storage steps. If you can't find them, it is often better to leave them and hope for the best, as excessive digging can disturb other plants. If you’d like more context on perennial performance, see Do You Have to Dig Up Tulip Bulbs Every Year?.
Do I need to treat the bulbs with chemicals before storing?
For home gardeners, chemical treatments are usually not necessary. The most effective "medicine" for a tulip bulb is dry air and good circulation. If you notice a tiny bit of surface dust, you can wipe it off. If a bulb is heavily diseased, the best course of action is to discard it rather than trying to treat it.
Why did my stored bulbs fail to bloom the following year?
The most common reason for a lack of blooms is digging the bulbs up too early, before the foliage had time to recharge the bulb. Another possibility is that the bulbs were stored in a place that was too hot, which can "cook" the flower bud inside. Ensure the foliage is fully yellow before lifting and keep storage temperatures below 75°F.
