Tools for Pruning Stella D’Oro Daylilies
- Sharp pruning shears or scissors
- Gloves (optional)
Step-by-Step Pruning Instructions
1. Remove Spent Flowers:
- Deadhead spent flowers by cutting the stem just below the flowerhead.
- This prevents seed formation, redirecting the plant’s energy towards new growth.
2. Trim Foliage:
- Cut back faded or yellowed foliage to the base of the plant.
- Remove any damaged or diseased leaves to prevent the spread of infection.
3. Cut Back Flower Scapes:
- Trim flower scapes (the stems that hold the flowers) to 2-3 inches above the ground.
- This encourages new growth and prevents the plant from becoming top-heavy.
4. Thin Clumps:
- If the daylily clump has become overcrowded, divide it by digging it up and separating the individual fans.
- Remove any dead or weak fans and replant the healthy divisions in well-drained soil.
5. Check for Pests and Diseases:
- Inspect the daylilies for any signs of pests or diseases.
- Remove any affected leaves or stems and treat the plant with appropriate remedies.
