Established lily clumps can become crowded over time, leading to fewer blooms and weaker plants. Dividing and replanting these lilies can rejuvenate your garden and promote healthy growth. This guide provides step-by-step instructions on how to successfully divide and replant your lilies.
When to Divide Lily Clumps
The best time to divide lilies is in early spring or immediately after they finish blooming in late summer to early fall. During this period, the plants are actively growing or have just completed their growth cycle, making it easier to transplant without stressing the plant.
Tools and Materials Needed
- Garden spade or shovel
- Garden fork
- Pruning shears or sharp knife
- Gloves
- Compost or organic matter
- Watering can or hose
- New planting site prepared with well-draining soil
Steps to Divide Lily Clumps
Follow these steps to carefully divide and replant your lilies:
1. Prepare the Area
Water the lily bed thoroughly a day before dividing to soften the soil and reduce stress on the plants during removal.
2. Dig Up the Clump
Use a garden fork or spade to gently loosen the soil around the clump. Carefully lift the entire clump out of the ground, being cautious not to damage the roots.
3. Divide the Clump
Place the clump on a clean surface. Use pruning shears or a sharp knife to cut the clump into sections, each with roots and at least one healthy growth point or “eye.” Ensure each division has enough roots to establish itself in the new location.
4. Prepare the New Planting Site
Choose a well-draining spot with rich, fertile soil. Amend the soil with compost or organic matter to promote healthy growth.
5. Replant the Divisions
Plant each division at the same depth it was growing before. Space the divisions about 8-12 inches apart, depending on the variety. Water thoroughly after planting to settle the soil around the roots.
Caring for Replanted Lilies
After replanting, provide consistent moisture and mulch around the plants to retain soil moisture and suppress weeds. Avoid fertilizing immediately; wait until the plants show new growth to apply a balanced fertilizer.
Tips for Successful Division
- Always use clean, sharp tools to prevent disease.
- Handle the roots gently to avoid damage.
- Divide lilies every 3-4 years to maintain healthy growth.
- Label divisions if you’re working with multiple varieties.
Dividing and replanting established lilies is a rewarding process that can rejuvenate your garden and produce more vibrant blooms. With proper timing, tools, and care, your lilies will thrive in their new spaces.
