Establishment
2-4 monthsYoung transplant with soft green foliage and minimal branching

Vegetative Growth
6-12 monthsBranching increases, foliage becomes denser and more silvery-green, plant fills out its natural mounding shape
Light pruning after frost danger passes to encourage bushiness. Minimal water once roots are established. Full sun exposure.
Pre-Flowering
4-8 weeksPlant reaches mature size and shape; flower buds begin forming at branch tips in late spring
Do not fertilize; reduce watering further. Ensure full sun and excellent drainage. No pruning unless shaping is needed.
Flowering
8-12 weeks (June-August typically)Abundant 2-3 inch pale pink flowers with deep crimson-maroon blotches blooming along stems throughout summer
Deadhead spent flowers to encourage continuous blooming. Minimal watering. Enjoy the blooms; very little intervention needed.
Post-Bloom & Dormancy
4-6 monthsFlowering tapers in late summer/fall; foliage remains evergreen and attractive; plant slows growth in winter
Stop deadheading in late summer to allow reseeding. Minimal water in winter. Light pruning to remove dead wood after frost threat passes.

Common Pests
-
Ensure excellent air circulation and drainage. Avoid overhead watering. Remove affected leaves. In severe cases, apply fungicide if needed; prevention is key.

Prevention is essential: use well-draining soil and water sparingly. If signs of root rot appear (wilting despite moist soil), reduce watering immediately and improve drainage. No cure exists; prevention is critical.
-
Spray with neem oil or insecticidal soap if webbing appears. Increase air circulation and mist foliage occasionally in very hot, dry conditions.
-
Use yellow sticky traps or spray with insecticidal soap. Ensure good airflow around plant.
