Ongoing Management
Planting
Plant in Spring. Ensure the root ball is level with the soil surface. Site in locations protected from wind to minimize the wind burn.
Slightly acidic soil (pH 6.0-7.0) is preferred.
Fertilization |
|
Apply a balanced, slow-release fertilizer in early Spring and again in mid-Summer for vigorous growth.
Watering |
|
Requires regular watering, especially during dry priods; keep soil consistently moist but not waterlogged.
Pruning / Cutting Back |
|
Deadheading will improve the plant's appearance.
Prune in late Winter or early Spring before new growth appears to remove dead stems and encourage bushier growth.
Integrated Pest & Pollinator Mgmt Notes |
|
Watch for aphids, Japanese beetles, caterpillars, mealybugs, scale insects, spider mites, thrips, and whiteflies. Monitor for fungal diseases like leaf spot and rust. Ensure good air circulation and avoid overhead watering.
Propagation |
|
Propagate through stem cuttings or division in Spring or early Summer.
Winter Protection |
|
Apply 2-3” layer of mulch around the base to retain moisture, control weeds, and protect the roots in Winter.
