Growth Stages

1

Establishment (Transplant)

4-6 weeks

Young plant settling into garden with initial silvery-green foliage; minimal flowering as energy goes to root development

Water regularly for first 4-6 weeks to establish roots. Mulch lightly around base (not touching stem). Avoid fertilizing heavy nitrogen.

2

Vegetative Growth

6-8 weeks

Plant develops fuller foliage structure with branching; silvery-green leaves expand and plant widens

Pinch back tips in early growing season to encourage bushier form. Maintain moderate water. Light feeding with balanced or bloom-promoting fertilizer.

3

Flowering (Spring-Summer)

12-16 weeks

Abundant spikes of deep raspberry-red flowers with dark burgundy calyces emerge; continuous bloom in cooler climates

Deadhead spent flower spikes to encourage continuous blooming. Keep soil consistently moist but not wet. High-potassium fertilizer supports prolonged flowering.

4

Peak Bloom & Pollinator Activity

6-10 weeks (summer peak)

Plant at full flowering with dense flower coverage; hummingbirds and bees actively visiting; rich color display

Minimal intervention; allow some flowers to remain for wildlife. Monitor for spider mites in dry heat. Ensure adequate water during hot spells.

5

Fall Decline & Dormancy

Variable by climate; 8-16 weeks

Flowering slows as temperatures cool; foliage may become slightly less vibrant; plant enters semi-dormant state in winter

Reduce watering significantly. In zone 8, provide frost cloth during hard freezes. Light pruning after first frost to shape. No fertilizing in fall/winter.

  • Ensure good air circulation; reduce overhead watering. Spray with sulfur or potassium bicarbonate if needed. Avoid high nitrogen fertilizer.

  • Prevent with excellent drainage and well-draining soil. Reduce watering in wet seasons. Remove affected plants if fungal rot occurs.
