Growth Stages

1

Establishment

First 1-2 years

Young plant focusing on root development with minimal flowering; foliage is compact and dense

Water regularly to keep soil consistently moist. Provide afternoon shade and shelter from wind. Avoid fertilizing heavily; use dilute, acidic fertilizer if needed.

2

Vegetative Growth

Late spring through summer

Plant develops mature branching structure and dense foliage; new shoots emerge in spring and summer

Pinch back new growth in late spring to encourage bushier form. Maintain consistent moisture. Apply mulch to regulate soil temperature and moisture.

3

Flower Bud Formation

August through November

Small flower buds develop along branch tips in late summer and fall; buds remain dormant over winter

Reduce nitrogen fertilizer to promote flower bud initiation. Provide consistent cool temperatures in fall. Do not prune during this period.

4

Blooming

4-6 weeks

Abundant small pink or rose flowers open in early spring (February-April depending on location); flowers cover the plant

Maintain consistent moisture during bloom period. Avoid disturbing plant or heavy pruning. Deadhead spent flowers to encourage tidier appearance, though not essential.

5

Post-Bloom & Summer

May through August

Flowers fade, new foliage emerges; plant returns to active vegetative growth

Light pruning can be done immediately after flowering to shape plant. Resume balanced fertilization if needed. Continue regular watering through summer.

Common Pests

  • Spray with insecticidal soap or neem oil in spring and early summer when insects are active. Maintain plant vigor through proper watering.

  • Increase humidity by misting foliage. Use miticide spray if infestation is severe. Avoid over-fertilizing with nitrogen.

  • Hand-pick if population is small. Use Bacillus thuringiensis (Bt) spray for larger infestations. Prune out heavily infested branches.

  • Ensure excellent drainage and avoid waterlogging. Do not plant in poorly drained soil. Remove affected plants if infection is severe.
