Growth Stages

1

Establishment

First 4-6 weeks after planting

Young plants with initial branch structure forming; minimal flowers.

Water regularly to keep soil consistently moist but not waterlogged. Mulch around base. Light pruning to shape if needed.

2

Vegetative Growth

Spring through early summer (4-8 weeks)

Rapid leaf and stem development; shrub fills out with fine, delicate foliage.

Continue regular watering during dry spells. Apply balanced fertilizer in early spring. Remove any dead or crossing branches.

3

Flowering

June through September (or first hard frost)

Abundant pure white five-petaled flowers cover the foliage; continuous bloom from early summer onward.

Deadhead spent flowers to encourage more blooms. Water during prolonged dry periods. Light pruning to maintain shape.

4

Late Season & Dormancy

October through November

Flowering gradually slows as temperatures cool. Foliage may take on bronze or golden tones before dropping.

Reduce watering as growth slows. Avoid heavy pruning late in season. Light cleanup of dead branches acceptable.

5

Winter Dormancy

December through February

Plant is fully deciduous with bare stems; no active growth.

No watering needed in most climates. Prune in late winter (February-March) to shape and remove winter damage before new growth.

Companion Planting

Plan your garden →

Plant with:

Russian sage (Perovskia) Lavender (Lavandula) Catmint (Nepeta) Thyme (Thymus) Salvia Coreopsis Juniper Santolina

Common Pests

  • Increase humidity with foliar misting; spray with neem oil or insecticidal soap if severe; prune heavily infested branches.

  • Improve air circulation through pruning; apply sulfur dust or fungicide spray; ensure adequate sun exposure.

  • Spray with horticultural oil in early spring before bud break; prune affected branches; repeat applications may be needed.

  • Spray undersides of leaves with insecticidal soap or neem oil; release beneficial insects like ladybugs in severe cases.
