Keeping Newly Purchased Bulbs Before Planting
It is a common scenario: your bulbs arrive from our nursery in New Jersey, but you aren't quite ready to put them in the ground. Perhaps the autumn weather is still a bit too warm, or your weekend schedule is packed. Knowing how to keep your tulip bulbs in peak condition during this waiting period is essential for their success.
When your package arrives, the first step is to open the box immediately. While we take great care to pack bulbs for safe transit, they are living things that need to breathe. Removing them from the shipping box prevents moisture from building up, which is the primary cause of mold or softening.
Prioritize Airflow and Ventilation
The most important rule for keeping bulbs before planting is to ensure they have plenty of fresh air. If your bulbs arrived in plastic bags with small holes, it is often better to move them into a paper bag, a mesh bag, or a shallow open tray.
Airflow keeps the outer skin of the bulb (called the tunic) dry. A dry tunic acts like a protective jacket, shielding the soft inner scales from damage. If you use a tray, spread the bulbs out in a single layer rather than stacking them deeply. This allows every bulb to stay cool and dry.
Choose a Cool, Dark Location
Tulip bulbs prefer a consistent temperature while they wait for their time in the soil. A spot that stays between 40°F and 70°F is ideal. Most gardeners find that an unheated basement, a ventilated garage, or a cool pantry works perfectly.
Avoid keeping your bulbs in areas that experience extreme temperature swings or high humidity, such as a laundry room or a spot near a heater. You should also keep them out of direct sunlight, as light can signal to the bulb that it is time to start growing before the soil is ready.
Key Takeaway: The Holding Period If you cannot plant your bulbs right away, remember the "Three Cs": Keep them Cool, Clean, and Covered (in a breathable material like paper or mesh). This simple step maintains the bulb's energy for spring.
Tulips
Why Gardeners Choose to Lift and Keep Bulbs
In many parts of the United States, tulips are treated as annuals—planted in the fall, enjoyed in the spring, and then composted. However, many gardeners choose to "lift" their bulbs (dig them up) to store them over the summer and replant them the following autumn. There are several positive reasons to take this extra step.
Protecting Against Summer Moisture
Tulips are originally from regions with very dry summers. In many American gardens, summer rain or irrigation for nearby perennials can make the soil too damp for a dormant tulip bulb. If a bulb sits in soggy soil during its summer rest, it may rot. By lifting the bulbs and keeping them in a dry place, you control their environment and keep them safe from excess water.
Making Room for Summer Annuals
If you have a small garden or a specific "cutting patch," space is at a premium. Once tulips finish blooming, their foliage takes several weeks to fade. By lifting the bulbs, you clear the area early, allowing you to plant summer favorites like zinnias, dahlias, or marigolds without disturbing the tulips' root systems later on.
Preventing Overcrowding and "Blind" Bulbs
Over time, tulip bulbs can produce small "offsets" or baby bulbs. If left in the ground for years, these clumps become crowded. When bulbs are too close together, they compete for nutrients and may stop flowering, producing only leaves (often called "going blind"). Lifting the bulbs allows you to sort through them, keeping the largest, healthiest ones for a guaranteed display next year.
How to Keep Tulip Bulbs After They Bloom
If you decide to save your bulbs for next year, the process starts while the plant is still in the garden. The transition from a flowering plant to a dormant bulb is a critical time for energy storage.
The Importance of Deadheading
As soon as the tulip petals begin to fade and drop, you should "deadhead" the plant. This simply means snipping off the spent flower head. By removing the developing seed pod, you tell the plant to stop spending energy on seeds and start sending that energy down into the bulb.
Be sure to leave the green stem and leaves intact. Do not cut the foliage back yet! Those green leaves are like solar panels, absorbing sunlight and converting it into the food the bulb needs to create next year’s flower bud.
Waiting for the Foliage to Yellow
Patience is a virtue when you are keeping tulip bulbs for the future. You must wait until the leaves have turned yellow or brown and have a papery texture before you dig them up. This usually happens about 6 to 8 weeks after flowering.
If you dig them up while the leaves are still green, the bulb will be "underfed" and may not have enough strength to bloom again. If the sight of yellowing leaves bothers you, try "interplanting" tulips with perennials like hostas or daylilies, which will grow up and naturally hide the fading tulip foliage.
What to Do Next: Post-Bloom Care
- Snap off the flower heads as soon as they fade.
- Continue to water lightly if the weather is extremely dry to keep the leaves working.
- Wait until at least 50-70% of the foliage is yellow before lifting.
- Avoid braiding or tying the leaves, as this reduces the surface area available for photosynthesis.
A Step-by-Step Guide to Lifting and Storing
Once the foliage has withered, it is time to bring your bulbs inside. Following a consistent routine ensures they stay healthy during their summer nap.
Digging and Cleaning
Using a hand trowel or a garden fork, gently loosen the soil around the bulbs. Start a few inches away from where the stem enters the ground to avoid accidentally slicing into the bulb. Lift the entire clump and gently shake off any loose dirt.
You can pull the dried foliage away from the bulb at this stage. It should come off easily with a light tug. If it resists, it may need another few days to dry out completely. Do not wash the bulbs with water; moisture is the enemy of stored bulbs. Instead, use your fingers or a soft brush to remove the remaining soil.
The Curing Process
"Curing" is a fancy word for letting the bulbs dry out thoroughly before long-term storage. Place your cleaned bulbs in a single layer on a screen, a newspaper-lined tray, or in a cardboard box.
Keep them in a well-ventilated, shaded area—like a porch or a garage—for about a week. This allows the outer skin to harden and any remaining moisture to evaporate. A well-cured bulb feels firm and dry to the touch, similar to an onion from the grocery store.
Sorting for Success
Before you pack them away, give your bulbs a quick inspection. This is the best way to ensure a high-quality display in the fall.
- Keep: Large, firm bulbs that feel heavy for their size.
- Discard: Bulbs that feel hollow, mushy, or show signs of significant mold.
- Small Offsets: You can keep the tiny baby bulbs, but be aware they may take a year or two of growth in a "nursery bed" before they are large enough to produce a full-sized flower.
"The secret to successful bulb storage is a dry environment. If you keep the bulbs away from moisture and provide plenty of airflow, they will remain dormant and healthy until planting time."
Finding the Perfect Summer Storage Spot
Now that your bulbs are cured and sorted, they need a home for the summer months. The goal is to keep them in a state of deep sleep.
Choosing the Right Container
Never store tulip bulbs in airtight plastic containers or sealed bags. Plastic traps moisture and heat, which leads to rot. Instead, use:
- Paper bags: These are inexpensive and breathable.
- Mesh bags: Old onion bags or specialized garden mesh bags provide excellent airflow.
- Cardboard boxes: A shallow box with a few holes poked in the sides works well.
- Trays: If you have the shelf space, leaving them spread out on a tray is the safest option.
Managing Temperature and Pests
The temperature should ideally stay between 60°F and 70°F during the summer. A dry basement or an interior closet is often better than an outdoor shed, which can become like an oven during July and August.
One practical challenge is keeping your bulbs safe from curious critters. Mice and squirrels find tulip bulbs quite tasty. If you live in an area with active rodents, consider storing your bulbs in a container made of fine wire mesh (hardware cloth) or hanging your mesh bags from a hook in the ceiling to keep them out of reach.
How to Tell if Your Kept Bulbs Are Still Healthy
As fall approaches and it is finally time to plant, you should check on your bulbs one last time. It is natural for bulbs to change slightly in appearance over the summer, but most should still be viable.
The "Squeeze Test"
A healthy tulip bulb should feel firm and solid, much like a fresh potato. If you gently squeeze the bulb and it feels "givey" or squishy, it has likely begun to rot inside. If it feels extremely light and "crackly," it may have dried out completely. In both cases, these bulbs should be tossed in the compost bin.
Identifying Surface Mold
It is common to see a small amount of blue or white surface mold on the outer tunic of the bulb. In most cases, this is harmless and can be lightly brushed off. As long as the bulb underneath is firm and the mold has not penetrated the layers, the bulb is perfectly fine to plant. Our 100% quality guarantee ensures that we send you the healthiest bulbs possible, and following these storage tips helps you keep them that way. If you want to read more about our policies, see the FAQs - General Bulbs and Plants. (longfield-gardens.com)
Watching for Sprouting
If you notice a small green "nose" (the sprout) beginning to emerge from the top of the bulb in late fall, don't worry! This is a sign that the bulb is healthy and ready to grow. Simply get it into the ground as soon as possible. The soil will protect the sprout from freezing temperatures.
Choosing Tulip Varieties That Are Easier to Keep
If your goal is to have tulips that return year after year with minimal effort, variety selection is the best place to start. While all tulips can be lifted and stored, some are much more "persistent" than others.
Darwin Hybrids
These are the heavy hitters of the tulip world. Known for their massive, classic cup-shaped flowers and sturdy stems, Darwin Hybrids are famous for their ability to return for several seasons. They are more tolerant of varying soil conditions and tend to "keep" their size better than other fancy varieties. If you like this style, consider the Tulip Darwin Hybrid Pink Impression. (longfield-gardens.com)
Species (Botanical) Tulips
If you want tulips that you don't have to lift at all, look toward species tulips. These are smaller, daintier flowers that are much closer to the original wild tulips. They are incredibly hardy and will often "naturalize," meaning they spread and multiply on their own in the garden if given good drainage and plenty of sun.
Fosteriana and Greigii Tulips
These categories are also known for their reliability. Fosteriana tulips (like the famous 'Emperor' series) have very large flowers and come back reliably for several years. Greigii tulips are prized not only for their blooms but also for their beautiful, mottled foliage, which adds interest to the garden even before the flowers open. For a bold spring combination, see the Tulip Darwin Hybrid Ad Rem & Queen of Night. (longfield-gardens.com)
Keeping Tulips in Containers
Growing tulips in pots is a wonderful way to bring color to your doorstep or patio. However, "keeping" bulbs in containers requires a slightly different approach than those in the ground.
Overwintering Pots
In colder climates (USDA zones 3-6), tulip bulbs in pots are more vulnerable to freezing and thawing than those in the ground. To keep them safe, move the pots into an unheated garage or shed once the plants have gone dormant in late fall. This provides a "buffer" from the most extreme temperatures while still giving the bulbs the cold period they need to bloom.
Summer Care for Potted Bulbs
If you want to reuse the bulbs from your containers next year, it is usually best to lift them from the pot once the foliage has yellowed. Potting soil tends to hold more moisture than garden soil, which increases the risk of rot during the summer. Follow the same lifting, curing, and storage steps used for garden bulbs, then replant them in fresh potting mix in the fall. If you’re looking for a larger planting, the Tulip Single Late Dordogne - Bulk Offer is a strong choice for plenty of blooms. (longfield-gardens.com)
Safety and Realistic Expectations
Gardening is a joyful partnership with nature, but it is always helpful to keep a few practicalities in mind.
Toxicity Awareness
It is important to remember that tulip bulbs are toxic if ingested by humans or pets. When you are keeping bulbs in your home—especially in paper bags that might look like snacks to a curious dog—ensure they are stored on high shelves or in areas that are inaccessible to children and animals. If you have sensitive skin, you may also want to wear gloves when handling large quantities of bulbs, as the "dust" from the tunics can sometimes cause mild irritation.
Understanding Bloom Quality
While lifting and storing bulbs is a great way to extend their life, tulips are naturally at their most vigorous in their first year. Commercial growers in places like Holland spend years creating the perfect conditions to produce "top-size" bulbs.
When we keep our own bulbs, the flowers in the second or third year might be slightly smaller, or the stems might be a bit shorter. This is a natural part of the plant's life cycle. Many gardeners enjoy this "cottage garden" look, but if you want a perfectly uniform display for a formal bed, you may choose to supplement your saved bulbs with fresh ones from us each year.

FAQ
Can I store tulip bulbs in the refrigerator?
You can store tulip bulbs in a refrigerator if you lack a cool garage or basement, but there is a catch. You must ensure there are no ripening fruits (like apples or pears) in the fridge, as they release ethylene gas. This gas can damage the flower bud inside the bulb, leading to "blind" plants that grow leaves but no flowers. If you need a quick zone check before chilling bulbs, revisit the Hardiness Zone Map. (longfield-gardens.com)
How long can tulip bulbs stay out of the ground?
Tulip bulbs can generally be kept out of the ground for about 6 to 10 months. They are meant to follow a yearly cycle: growing in spring, resting in summer, and developing roots in fall. While they can survive a bit longer in ideal conditions, they perform best when they are replanted during the autumn following their last bloom.
What happens if I plant a soft or mushy bulb?
It is best to discard any bulbs that feel soft or mushy. These bulbs have likely begun to rot or are infected with a fungus. Planting them will not only result in a failed bloom, but the rot can sometimes spread to healthy bulbs nearby in the soil. Always stick to the "squeeze test" before planting.
Do I need to wash my tulip bulbs before storing them?
No, you should never wash tulip bulbs with water before storage. Moisture trapped between the layers of the bulb or under the skin can quickly lead to rot. Instead, let the bulbs dry out and then gently brush off any excess soil with your hands or a soft, dry cloth.
