Dividing and transplanting lilies can rejuvenate your garden and promote healthy growth. With proper techniques, you can ensure your lilies thrive for years to come. This guide provides step-by-step instructions to help you successfully divide and transplant lilies.
Understanding When to Divide Lilies
The best time to divide lilies is in late summer to early fall, after the flowering period. During this time, the plant has stored energy in its bulbs, making it easier to divide without stressing the plant. Avoid dividing lilies in early spring or late winter, as they are not yet fully active or are preparing for dormancy.
Tools and Materials Needed
- Garden spade or fork
- Sharp knife or pruning shears
- Gloves
- Garden compost or well-draining soil
- Watering can or hose
- Mulch (optional)
Steps to Divide Lilies
Follow these steps to carefully divide your lilies:
1. Prepare the Area
Water the lily bed thoroughly a day before dividing to soften the soil and reduce root damage during digging.
2. Dig Up the Clump
Use a garden spade or fork to gently loosen the soil around the lily clump. Carefully lift the entire clump out of the ground, supporting the roots.
3. Divide the Clump
Inspect the clump for natural divisions. Using a sharp knife or shears, cut the clump into sections, each with at least one healthy bulb and roots. Discard any damaged or diseased parts.
4. Prepare the Divisions for Replanting
Trim any damaged roots and remove old or dead foliage. Dip the bulbs in a fungicide solution if necessary to prevent disease.
Transplanting Lilies
Follow these steps to successfully transplant your divided lilies:
1. Choose the Right Location
Select a site with well-draining soil and full sun to partial shade. Lilies prefer slightly acidic to neutral soil.
2. Plant the Divisions
Dig holes about 4-6 inches deep and space them 8-12 inches apart. Place each bulb with the pointed end facing up. Cover with soil and gently firm it down.
3. Water and Mulch
Water the newly planted bulbs thoroughly. Apply a layer of mulch around the plants to retain moisture and suppress weeds.
Aftercare and Tips
Proper aftercare ensures your lilies establish well and bloom beautifully the following season.
- Keep the soil consistently moist but not waterlogged.
- Fertilize with a balanced, slow-release fertilizer in early spring and after flowering.
- Remove spent flowers to encourage new growth.
- Apply mulch annually to protect roots and maintain soil moisture.
With patience and proper technique, dividing and transplanting lilies can rejuvenate your garden and provide stunning blooms year after year.
