Growth Stages

1

Establishment

4-8 weeks

Young plant with dormant buds; minimal growth in first weeks after planting

Water regularly, mulch around base, avoid pruning first season. Monitor for transplant stress.

2

Vegetative Growth

Spring through early summer

Shoot and leaf development; plant fills out with branching growth and fine green foliage

Water deeply during dry periods. Fertilize in early spring with balanced fertilizer. Remove dead or weak branches.

3

Pre-Flowering Bud Formation

Late summer through fall

Flower buds develop on branch tips; plant appears fuller with abundant buds along branches

Do not prune after late summer to avoid removing next year's flower buds. Maintain consistent moisture.

4

Flowering

4-6 weeks in spring (April-May in most zones)

Abundant white double flowers cover arching branches in dense clusters; peak ornamental display

Deadhead spent flowers if desired, though not necessary. Flowers typically last 4-6 weeks. Enjoy the display and allow bees to visit.

5

Post-Bloom and Summer

June through fall

Flowers fade; foliage remains green and fine-textured throughout summer; plant maintains shape

Remove old flower clusters if desired. Prune immediately after flowering if needed to shape plant. Summer pruning after bloom won't affect next year's flowers.

Common Pests

  • Spray with strong water stream to dislodge; use insecticidal soap or neem oil if infestation persists

  • Increase humidity with regular watering; spray foliage with water; use miticide if severe

  • Hand-pick in early morning; use pheromone traps; apply neem oil or spinosad spray

  • Prune affected branches 12 inches below visible damage; sterilize pruning tools between cuts; improve air circulation
