Digging Up and Storing Bulbs for Winter

As the growing season winds down and frost begins to settle in, it’s time to think about lifting and storing your tender bulbs to protect them through the winter. Proper care can ensure vibrant blooms next year!

1. Know When to Dig

Timing is everything when it comes to digging up bulbs.

• Wait for dieback: Let the foliage die back naturally after the first frost. This signals the bulb has stored enough energy for next season.
• Avoid frost damage: Digging too soon can harm the bulb, while waiting too long may expose it to freezing temperatures underground.

2. Dig Up and Clean the Bulbs

• Use the right tool: A garden fork is ideal to gently lift bulbs without damaging them.
• Lift carefully: Dig around and under the bulb to avoid cutting roots or bruising the bulb.
• Clean gently: Shake or brush off excess soil—no need to wash them.

3. Dry the Bulbs

• Air-dry: Place bulbs in a well-ventilated, dry area for about a week.
• Trim foliage: Once dry, remove any remaining leaves or stems.

4. Prepare for Storage

• Choose ventilated containers: Cardboard boxes, mesh bags, or crates work well.
• Add insulation: Layer bulbs with peat moss, sawdust, or vermiculite to prevent them from touching and to retain just enough moisture.
• Label everything: Include bulb type and color for easy spring planting.

5. Store the Bulbs

• Find the right spot: Store bulbs in a cool 7–13°C, dark, and dry location that won’t freeze.
• Ideal places: Unheated garages, basements, or root cellars are perfect.
• Monitor regularly: Check for signs of rot or mold and remove affected bulbs.

Spring & Summer Bulb Tips

Spring Bulbs (e.g., Daffodils, Crocus)

• Dormancy begins: Once foliage turns brown and papery in late spring or early summer, bulbs are dormant and ready to be lifted if needed.
• Divide every 5 years: Overcrowding leads to smaller blooms and uneven growth. Dig, divide, and replant to refresh your beds.

Summer Bulbs (e.g., Dahlias, Begonias)

• Lift after frost: Wait until frost blackens the foliage, then gently dig up the bulbs.
• Dry before storing: Allow leaves to dry naturally before trimming. Dust bulbs with fungicide to prevent rot.
• Store smart: Use paper bags or nylon stockings with dry peat moss. Keep in a frost-free, well-ventilated area between 16–18°C.

Conclusion

While many bulbs can stay in the ground for years, lifting and storing tender varieties ensures they survive harsh winters and thrive come spring. With a little care and attention, your garden will reward you with a stunning display year after year.
