How to Overwinter Lily Bulbs
Garden enthusiasts treasure the unique beauty and fragrance that lilies bring to their gardens. However, in many climates, these delicate flowers won’t survive the harsh winter months without intervention. To ensure your lily bulbs continue to enchant you each year, learning how to overwinter them is crucial. In this article, we will explore the various techniques to protect your lily bulbs throughout winter and ensure a thriving bloom come springtime.
1. Preparing the bulbs for storage:
Before the first frost hits, it’s essential to dig up and prepare lily bulbs for storage. Delicately loosen the soil surrounding your lilies using a garden fork or spade, taking care not to damage the bulbs in the process. Then, lift the bulbs from the ground and remove excess soil clinging to them. If you observe any rotten or damaged bulbs, discard them immediately to avoid contamination.
2. Curing the lily bulbs:
Curing is essential to prevent fungal infections during storage and harden off any tender tissue. Lay out your freshly dug lily bulbs in a well-ventilated area that is cool and dry for about a week. Don’t expose them to freezing temperatures or direct sunlight during this process.
3. Packing and storing your bulbs:
After curing, pack your lily bulbs in slightly damp peat moss, perlite, or vermiculite to maintain optimal humidity levels during storage. Fill a plastic bag or a perforated container with this packing material and gently place your bulbs inside, ensuring they don’t touch one another.
Seal the container but remember to poke small holes in it for airflow if using a plastic bag. Store the packed lily bulbs in a dark and cool space such as a basement, garage, or even your refrigerator’s vegetable crisper drawer if space permits. The ideal storage temperature lies between 35°F (2°C) and 45°F (7°C).
4. Checking on the stored bulbs:
Throughout winter, periodically check on your stored lily bulbs to ensure they remain healthy and free of mold or rot. If you notice any signs of decay, promptly remove and discard the affected bulbs from the container.
5. Replanting in early spring:
Once the threat of frost has passed and you notice the soil thawing, it’s time to replant your overwintered lily bulbs. Choose a well-drained location in your garden that receives ample sunlight — lilies prefer at least six hours of direct sunlight. Place the lily bulbs 6 to 8 inches apart and cover them with 3 to 6 inches of soil, depending on the bulb size. Water them well after planting to help settle the soil and begin their blooming journey anew.
By carefully following these steps for overwintering lily bulbs, you can preserve their beauty right through winter, ensuring a spectacular burst of color and fragrance when spring arrives!
