Low Maintenance Care

Consistent moisture, seasonal grooming, and mulch keep plants lush and clean through heat and storms.

• Watering: Deeply soak when the top 1 in is dry; increase frequency during hot spells and in pots.
• Pruning: Remove spent scapes after bloom and trim tattered leaves; cut back foliage after frost.
• Fertilizing: Top-dress with compost in spring; apply a balanced, slow-release fertilizer if growth is light.
• Mulching: 1 to 2 in of shredded bark or leaf mold, keeping mulch off crowns.
