Asiatic lilies are a popular choice for gardeners due to their vibrant colors and hardy nature. However, to ensure they survive the winter and flourish again in the spring, proper digging and storage techniques are essential. This guide provides best practices for digging up Asiatic lilies for winter storage, helping you maintain healthy plants year after year.
When to Dig Up Asiatic Lilies
The ideal time to dig up Asiatic lilies is in late fall, after the foliage has yellowed and died back naturally. This typically occurs after the first frost but before the ground freezes solid. Timing is crucial to prevent damage to the bulbs and ensure they are healthy for storage.
Tools Needed for Digging
- Garden fork or spade
- Gloves
- Bucket or wheelbarrow
- Clean, sharp knife or garden shears
- Storage containers or paper bags
- Bleach solution (optional for disinfecting tools)
Steps for Digging Up Asiatic Lilies
Follow these steps to carefully dig up your Asiatic lilies:
- Water the soil around the plants a day before digging to soften it.
- Use a garden fork or spade to gently loosen the soil around the lily clump.
- Carefully lift the entire clump out of the ground, avoiding damaging the bulbs.
- Shake off excess soil and inspect the bulbs for any signs of disease or damage.
- Use a clean knife or shears to cut away any damaged or diseased parts.
Cleaning and Preparing the Bulbs
After digging, clean the bulbs thoroughly to prevent rot during storage. Disinfect tools between cuts to prevent spreading diseases. Allow the bulbs to dry in a cool, airy place for a few days before storage.
Storage Conditions for Asiatic Lily Bulbs
Proper storage is key to overwintering Asiatic lilies successfully. Keep the bulbs in a cool, dry, and well-ventilated environment. Ideal storage temperatures are between 35°F and 50°F (2°C to 10°C). Avoid storing bulbs in plastic bags, which can trap moisture and lead to rot.
Storage Methods
- Wrap bulbs in paper or burlap to absorb excess moisture.
- Place wrapped bulbs in mesh bags or cardboard boxes with ventilation holes.
- Label each bag or container with the variety and date of storage.
- Store in a cool, dark place such as a basement, garage, or cellar.
Resuming Growth in Spring
As temperatures rise in spring, check your stored bulbs periodically. When the risk of heavy frost has passed, you can replant the bulbs in the garden. Choose a sunny location with well-draining soil for optimal growth.
Additional Tips
- Avoid damaging the bulbs during digging to ensure healthy regrowth.
- Discard any bulbs that show signs of mold, rot, or disease.
- Consider dividing large clumps to promote better flowering in the following season.
- Maintain good garden hygiene by removing old foliage and debris.
By following these best practices, you can ensure your Asiatic lilies survive the winter and reward you with beautiful blooms each year. Proper digging, cleaning, and storage are vital steps in maintaining a healthy and vibrant garden.
