Introduction
The sight of the first tulips pushing through the spring soil is one of the most rewarding moments for any gardener. Those bright, cup-shaped blooms bring a sense of joy and the promise of warmer days ahead. Whether you are looking to change your garden’s color palette or simply need to move your bulbs to a sunnier spot, you may find yourself wondering if you can safely lift them from the ground. While this guide focuses on tulips, the same principles for digging up bulbs and replanting often apply to other spring favorites like daffodils, hyacinths, and crocuses.
At Longfield Gardens, we believe that gardening should be a rewarding and straightforward experience. Moving your tulip collection is a common task that allows you to refresh your landscape and keep your flower beds looking their best. While tulips are often treated as annuals in many American gardens, you can certainly dig them up and replant them to enjoy their beauty in a new location.
This guide will walk you through the simple steps of lifting, storing, and replanting your tulip bulbs. We will cover the best timing for moving bulbs, how to keep them healthy while they are out of the ground, and how to ensure they have a successful return next spring. With a few basic techniques, you can confidently manage your tulip collection and create the garden of your dreams.
Digging and replanting tulip bulbs is an easy way to customize your spring display and ensure your plants stay healthy for years to come.
Should You Dig Up Your Bulbs?
Before you reach for the shovel, it is helpful to decide if your bulbs actually need to be moved. While some gardeners lift their bulbs every year, it isn't always necessary. You should consider digging up bulbs and replanting if you notice any of the following:
- Overcrowding: Your tulip patch has become a dense mat of leaves with fewer and smaller flowers than in previous years.
- Relocation: You are redesigning your garden or moving to a new home and want to take your favorites with you.
- Poor Performance: The bulbs are in a spot that has become too shady or where the soil stays consistently soggy, risking rot.
- Pest Pressure: Local wildlife like voles or squirrels are consistently raiding your garden beds during the dormant season.
- Variety Type: You are growing specialized hybrids that require a very dry summer dormant period to survive, which your local climate may not provide naturally.
When Is the Best Time to Dig Up Tulips?
Timing is the most important factor when you decide to dig up your tulip bulbs. If you lift them too early, the bulb may not have enough energy to produce a flower the following year. If you wait too long, the foliage will disappear completely, making it very difficult to find the bulbs without accidentally damaging them with your shovel.
The Foliage Rule
The most reliable sign that your tulips are ready to be moved is the condition of their leaves. After the flowers fade, the plant begins to shift its energy from blooming to rebuilding the bulb for the next season. The leaves act like solar panels, soaking up sunlight and converting it into food that is stored deep inside the bulb.
You should wait until the foliage has turned completely yellow or brown and has begun to wither. This usually happens about six to eight weeks after the flowers have finished blooming. When the leaves are limp and dry, it indicates that the bulb has finished its growth cycle for the year and is entering its dormant phase.
Summer vs. Fall Digging
Most gardeners choose to dig up their tulips in early summer once the foliage has died back. This allows you to clear the space for summer annuals or perennials. Once dug, the bulbs can be stored in a cool, dry place until it is time to plant them again in the fall.
Alternatively, some gardeners prefer to move tulips directly from one spot to another in the fall. If you choose this route, you must mark the location of the bulbs while the leaves are still visible in the spring. Without a marker, it is nearly impossible to find the exact spot once the foliage has completely decomposed into the soil.
Key Takeaway: Always wait for the tulip leaves to turn yellow or brown before digging. This ensures the bulb has stored enough energy to bloom again next spring.
Step-By-Step Guide to Digging Up Tulip Bulbs
Lifting tulip bulbs is a simple process that requires only a few basic tools. A hand trowel or a garden spade is usually all you need to get the job done.
Prepare the Area
Before you start digging, clear away any mulch or debris from around the base of the tulip stems. If the foliage is still attached but dry, you can use it as a handle to help guide your digging, but be careful not to pull on it too hard. If the leaves break off, you might lose track of where the bulb is located.
Digging with Care
Insert your trowel or spade into the soil about four to six inches away from the stem. This distance helps prevent you from accidentally slicing into the bulb. Gently pry the soil upward to loosen it. tulip planting depth is typically about six inches, so you will need to dig down at least that far to reach the bottom of the bulb.
Once the soil is loose, reach in with your hands to lift the bulbs out. You may find several smaller "bulblets" attached to the main bulb. These are young tulips that the parent plant has produced. When you encounter these bulblets, you have a choice. If you want to expand your garden, you can gently separate the small offsets from the parent bulb and plant them in a nursery bed. If you prefer a denser clump, you can leave the smaller bulbs attached. Keep in mind that smaller offsets usually require a year or two of leafy growth before they are large enough to produce a flower.
Cleaning the Bulbs
Once the bulbs are out of the ground, gently shake them to remove any large clumps of soil. Use your fingers to brush away remaining dirt, but do not wash them with water. Introducing moisture at this stage can lead to rot or fungal issues during storage.
Check each bulb for signs of damage or disease. A healthy tulip bulb should feel firm and heavy for its size, similar to a high-quality onion. If a bulb feels mushy, looks shriveled, or has large dark soft spots, it is best to discard it. Keeping only the healthiest bulbs ensures a better show in your garden next year.
What to do next:
- Locate the withered foliage to find your bulbs.
- Dig a wide circle around the plant to avoid damage.
- Lift the bulbs gently by hand once the soil is loose.
- Remove loose dirt without using water.
- Discard any bulbs that feel soft or look diseased.
How to Cure and Store Tulip Bulbs
If you are not replanting your tulips immediately, you must "cure" them before putting them into storage. Curing is simply a fancy word for letting the outer skin of the bulb dry out. This toughens the protective layer and prevents the bulb from losing too much moisture over the summer.
The Curing Process
Place your cleaned bulbs in a single layer on a tray, a piece of cardboard, or a screen. Keep them in a shaded, well-ventilated area such as a garage or a covered porch. Do not leave them in direct sunlight, as this can overheat the bulbs and damage the flower embryo inside.
Let the bulbs dry for three to five days. During this time, any remaining bits of soil will dry up and fall off easily. You can also trim away the remaining dry foliage and any long, wiry roots at this stage.
Choosing a Storage Location
Once the bulbs are dry, they need a home for the summer. The ideal storage spot is cool, dark, and dry with plenty of air circulation. A basement, a cool closet, or a ventilated shed are usually great options. Aim for temperatures between 60°F and 70°F.
Avoid storing bulbs in airtight plastic containers or bags. Plastic traps moisture, which leads to mold and rot. Instead, use breathable containers such as:
- Paper lunch bags with a few holes punched in them.
- Mesh produce bags (like the ones used for onions).
- Cardboard boxes lined with a layer of dry peat moss or newspaper.
- Old nylon stockings.
A Note on Refrigeration
In very warm climates, some gardeners store tulip bulbs in the refrigerator to give them the "chill time" they need to bloom. If you do this, keep the bulbs away from ripening fruit like apples or pears. These fruits release ethylene gas, which can kill the flower bud inside the tulip bulb.
Key Takeaway: Cure bulbs in a shaded, airy spot for a few days before storing them in breathable bags. This prevents rot and keeps the bulbs healthy until fall.
Replanting Your Tulip Bulbs in the Fall
When the crisp air of autumn arrives and soil temperatures begin to drop, it is time to get your tulips back into the ground. The ideal window for replanting tulip bulbs is when the soil temperature 50–60°F. This typically aligns with the time after your local first frost date but before the ground freezes solid. Waiting for these cooler temperatures prevents the bulbs from sprouting too early and helps them focus on root development.
Selecting the Right Spot
Tulips love the sun. When choosing a new location for your replanted bulbs, look for a spot that receives at least six hours of direct sunlight per day. They also require soil that drains well. If water tends to puddle in an area after a rainstorm, that spot is likely too wet for tulips and may cause the bulbs to rot over the winter.
If you have heavy clay soil, you can improve drainage by mixing in some compost or aged bark. This creates a looser structure that allows water to move away from the bulbs more quickly. We at Longfield Gardens always recommend starting with good soil to give your plants the best possible foundation.
Planting Depth and Spacing
A good rule of thumb for any bulb is to plant it three times as deep as the bulb is tall. For most tulips, this means digging a hole about six to eight inches deep. Planting at the correct depth protects the bulbs from temperature swings and hungry critters.
Place the bulb in the hole with the pointy end facing up. This is where the stem will emerge. The flat end with the wiry roots should face down. Space your bulbs about four to six inches apart to give them room to grow, or plant them in small clusters of five to seven for a more natural, bouquet-like look.
Finishing Touches
Once the bulbs are in the ground, fill the hole with soil and lighty press down with your hands to remove any large air pockets. Water the area well immediately after planting. This settles the soil around the bulbs and triggers them to start growing roots before the ground freezes.
After watering, you can add a two-inch layer of mulch, such as shredded leaves or bark. Mulch helps regulate soil temperature and keeps moisture levels consistent throughout the winter months.
What to Expect After Replanting
Once your bulbs are back in the ground, they will spend the winter forming a robust root system. During the first spring after replanting tulip bulbs, you may notice that the blooms are slightly smaller than they were previously. This is a normal part of the recovery process as the bulb acclimates to its new environment.
To help them bounce back, ensure the area is well-watered during dry spells in the spring and leave the foliage intact until it turns yellow naturally. This allows the bulb to maximize its energy storage for the following year. While the first year might be a period of adjustment, proper care ensures a much stronger show in subsequent seasons.
Missing the Fall Window: Backup Plans
If life gets in the way and you miss the ideal fall planting window, don’t panic. There are still ways to save your bulbs:
- Late Planting: If the ground isn't frozen, you can still plant your bulbs as late as December or early January. They may bloom a bit later in the spring, but they will likely survive.
- Potted Storage: If the soil is frozen solid, you can plant the bulbs in large pots filled with potting soil and keep them in an unheated garage or basement until spring. This provides the necessary cold period while keeping them safe from extreme deep freezes.
- Avoid Long Storage: Do not attempt to keep bulbs out of the ground for more than a year. They will eventually dry out and lose their vitality. If you find forgotten bulbs in the spring, it is better to plant them immediately than to wait for the next fall.
Moving Tulips Immediately: The "In-the-Green" Method
While storing bulbs over the summer is the most common practice, sometimes you need to move a plant right away. Perhaps you are doing a construction project or a neighbor has offered you some of their extras while they are still blooming. This is often called moving them "in the green."
How to Move Active Plants
Moving tulips while they are still growing or blooming is a bit more stressful for the plant, but it can be done successfully. The key is to keep as much soil around the roots as possible. Instead of lifting a bare bulb, dig a large clump of soil that contains the bulb and its entire root system.
Transport the clump to its new home immediately and plant it at the same depth it was growing previously. Water it thoroughly to help the roots settle into the new soil.
What to Expect
If you move tulips while they are in bloom, the flowers may wilt quickly. This is normal. The plant is focusing its energy on its roots rather than the blossom. Do not cut the leaves off after moving them; let them die back naturally in the new location so the bulb can recharge for next year. While they may not look perfect the first season after an immediate move, they should recover and bloom beautifully the following spring.
Why Replant? Understanding Tulip Behavior
You might wonder why some people dig up their tulips every year while others leave them alone. The answer often depends on the type of tulip you are growing and your specific garden goals.
Annual vs. Perennial Tulips
Many of the most spectacular, large-flowered tulips—like the Parrot or Double varieties—are bred for a one-time show. They often behave like annuals, meaning they bloom beautifully the first year but may not return with the same vigor. For these types, many gardeners prefer to dig them up and replace them with fresh bulbs from us to guarantee a perfect display.
However, other varieties are much better at "perennializing," or coming back year after year. Darwin Hybrid tulips, Emperor tulips, and Species (botanical) tulips are known for their longevity. These varieties are the best candidates for digging and replanting if you want to expand your garden or share them with friends.
Managing Overcrowded Bulbs
Even the best perennial tulips can eventually become overcrowded. Over time, the parent bulb produces many small bulblets. When too many bulbs are competing for the same nutrients and space, the flowers may become smaller or the plants may stop blooming entirely.
If you notice your once-vibrant tulip patch is mostly leaves and very few flowers, it is a sign that it is time to dig them up and spread them out. Dividing these clumps every three to four years keeps the plants healthy and gives you more bulbs to plant in other parts of your yard.
Protecting from Pests and Rot
In some regions, garden pests like squirrels, voles, or chipmunks are very fond of tulip bulbs. Digging them up in the summer and storing them safely indoors is one way to protect your investment from hungry wildlife.
Similarly, if your garden bed stays very wet during the summer due to irrigation or heavy rain, tulips left in the ground may rot. Lifting them during their dormant period ensures they stay dry and healthy until the cooler, drier weather of fall returns.
Common Questions About Moving Tulips
As you plan your garden changes, you might have a few specific questions about the logistics of moving bulbs. Most gardening tasks are easier than they seem once you understand the basic needs of the plant.
Can I move tulips in the spring?
Yes, you can move tulips in the spring, but it is best to wait until after the flowers have faded. Moving them while they are in full bloom can cause the flowers to drop prematurely. If you must move them in the spring, keep the soil intact around the roots and water them well after replanting.
What if I accidentally sliced a bulb?
Accidents happen! If you slice a small piece off the side of a bulb, it may still survive. However, if the bulb is cut in half or the bottom (basal plate) where the roots grow is destroyed, it is unlikely to grow. If you have plenty of other bulbs, it is usually safer to discard the damaged one to prevent disease from entering the soil.
Do I need to fertilize when I replant?
While not strictly necessary if you have good soil, a small amount of bulb fertilizer can be helpful. You can mix a granular bulb food into the bottom of the planting hole. Avoid high-nitrogen fertilizers, as these encourage leaf growth but can discourage the bulb from forming a strong flower for the next year.
How long can bulbs stay out of the ground?
Tulip bulbs can stay out of the ground for several months if they are stored in a cool, dry place. Most gardeners dig them in June or July and replant them in October or November. However, they should not stay out of the ground for more than a year. They need a period of growth and a period of cold to stay alive and healthy.
Final Tips for Success
Moving your tulips is a wonderful way to take control of your garden’s design and ensure your plants are in the best possible environment. Whether you are dividing a crowded clump or relocating a favorite variety to a new flower bed, the process is straightforward and rewarding.
At Longfield Gardens, we want every gardener to feel confident in their ability to grow a beautiful spring landscape. By following the natural lifecycle of the tulip—waiting for the leaves to yellow, curing the bulbs properly, and replanting at the right depth in the fall—you are setting yourself up for a stunning display of color.
Remember that gardening is a continuous learning process. Every soil type and microclimate is a little different, so don't be afraid to observe your plants and see how they respond. With a little patience and these simple steps, your tulips will continue to be a highlight of your spring garden for years to come.
Key Takeaway: Replanting tulips is a low-stress way to refresh your garden. Focus on healthy bulbs, proper storage, and a sunny new location for the best results.

FAQ
How deep should I replant my tulip bulbs?
Replant tulip bulbs about 6 to 8 inches deep, or roughly three times the height of the bulb itself. Planting at this depth protects the bulb from freezing temperatures and prevents animals from easily digging them up. Always place the bulb with the pointed end facing up toward the sky.
Can I replant tulip bulbs immediately after digging them up?
Yes, you can replant them immediately if the foliage has already died back naturally. If you are moving them "in the green" while they still have leaves, keep as much soil around the roots as possible and water them thoroughly. However, most people store them over the summer to keep the bulbs dry and safe until the fall planting season.
Why didn't my replanted tulips bloom the following year?
The most common reason is that the foliage was cut back too early the previous spring, preventing the bulb from storing enough energy. Other factors include planting in a spot that is too shady, soil that stays too wet, or using bulbs that are naturally short-lived hybrids. Ensure they get plenty of sun and have well-draining soil for the best chance of a return bloom.
Do I need to wash the bulbs before storing them?
No, you should never wash tulip bulbs with water before storage. Moisture is the enemy of a dormant bulb and can quickly cause mold or rot. Instead, let the bulbs dry out in a shaded area and then gently brush off any remaining dirt with your hands or a soft brush.
