Seedling
3-4 weeksTiny seedlings with first true leaves appearing; slow initial growth phase
Keep soil consistently moist but not waterlogged. Provide bright light. Thin seedlings to prevent crowding and fungal issues.
Vegetative Growth
2-3 monthsYoung plants develop dense, fine-textured evergreen foliage; gradually increasing in width and mounding habit
Water during dry spells but allow soil to dry between waterings. Avoid excessive nitrogen fertilizer which promotes leafy growth over flowers. Light pruning helps establish shape.
Pre-flowering
2-3 weeksBuds form within the dense foliage; plants appear slightly mounded with emerging flower buds visible
Continue moderate watering. Do not fertilize heavily. Ensure adequate sunlight for robust flowering.
Flowering
4-6 weeks (spring, typically April-May)Dense clusters of small, fragrant white flowers cover the plant; blooming period is prolific and eye-catching
Deadhead spent flowers to encourage extended blooming, though not essential. Reduce watering slightly. Do not fertilize during bloom.
Post-flowering & Dormancy
6-8 monthsFlowers fade; plant returns to foliage display; foliage remains evergreen and decorative throughout fall and winter
Light pruning after flowering helps maintain compact shape and prevents legginess. Minimal water needed except during drought. Prepare for winter dormancy in colder zones.
