Dividing tiger lilies is a rewarding gardening task that helps keep your plants healthy and vigorous. Proper division prevents overcrowding, encourages new growth, and ensures beautiful blooms year after year. However, it’s essential to do it correctly to avoid stressing the plant. This guide provides simple steps to divide tiger lilies safely and effectively.
Understanding When to Divide Tiger Lilies
The best time to divide tiger lilies is in early spring or immediately after they finish blooming in late summer. During this period, the plant is actively growing or entering dormancy, which helps it recover quickly from the division process.
Tools Needed for Division
- Sharp garden spade or shovel
- Garden fork or rake
- Clean, sharp pruning shears
- Gloves to protect your hands
- Water for soaking and cleaning
Step-by-Step Division Process
1. Prepare the Plant
Water the tiger lily thoroughly a day before dividing. This softens the soil and reduces stress on the plant during removal.
2. Dig Around the Plant
Carefully dig a wide circle around the clump using a spade or garden fork. Loosen the soil and gently lift the entire plant from the ground.
3. Divide the Clump
Shake off excess soil and examine the root system. Use clean shears to cut apart the clump into smaller sections, each with roots and at least one healthy shoot or leaf cluster.
4. Prepare New Planting Sites
Choose well-drained, fertile soil in a sunny location. Amend the soil with compost if necessary. Dig holes large enough to accommodate the roots of each division.
5. Plant the Divisions
Place each division into its hole, ensuring the crown is level with the soil surface. Fill in with soil and water thoroughly to settle the roots.
Post-Division Care
Water the newly planted divisions regularly, especially during dry spells. Mulch around the plants to conserve moisture and suppress weeds. Avoid fertilizing immediately after division; wait until new growth appears.
Tips for Stress-Free Division
- Perform division during cool, cloudy days to minimize stress.
- Handle roots gently to prevent damage.
- Use clean tools to prevent disease transmission.
- Allow newly divided plants time to establish before heavy flowering.
- Monitor for pests and diseases after planting.
With proper timing and gentle handling, dividing tiger lilies can be a straightforward process that benefits your garden. Enjoy lush, healthy blooms for years to come!
