Growth Stages

1

Establishment

First 6-12 months

Recently planted shrub with small branching framework and minimal foliage

Water regularly to establish deep roots. Mulch around base. Avoid heavy pruning first year.

2

Vegetative Growth

Years 1-3

Dense branching structure develops with healthy green foliage; shrub fills out its mature width

Prune lightly after flowering to maintain shape. Fertilize in early spring with balanced fertilizer.

3

Flowering

4-6 weeks, typically April-May depending on zone

Small, delicate white or pale pink star-shaped flowers cover branch ends in dense clusters (racemes)

Deadhead spent flowers if desired to encourage bushier growth. Do not heavily prune during bloom.

4

Post-Flowering

June-September

Flowers fade and drop; shrub produces seed capsules; foliage remains healthy throughout summer

Light pruning acceptable now to shape plant. Remove any dead or crossing branches.

5

Dormancy

October-March

Foliage turns yellow to reddish in fall; leaves drop; plant enters winter rest

No pruning needed. Mulch base for winter protection in colder zones. Do not fertilize.

  • Prune out heavily infested branches; spray dormant oil in early spring; use insecticidal soap in growing season

  • Increase humidity; spray foliage with water; apply miticide if populations are high

  • Hand-pick early morning; use beetle traps nearby; apply neem oil or pyrethrin if needed
