Establishment
3-6 months after plantingNewly planted shrub develops root system and produces initial vegetative growth
Water regularly to keep soil moist. Mulch with 2-3 inches of pine bark or oak leaves. Avoid fertilizing year one. Protect from direct afternoon sun and strong winds.
Vegetative Growth
Spring through mid-summerShrub expands canopy with new shoots and leaves throughout spring and early summer
Apply balanced, acidic fertilizer (10-10-10 or similar) in early spring after growth begins. Prune lightly after blooming to shape. Keep mulch layer consistent.
Flowering
4-6 weeks in mid-to-late springBuds swell and open into clusters of pure white flowers with yellow stamens
Ensure consistent moisture; wilting during bloom reduces flower quality. Do not fertilize during bloom. Deadhead spent flowers by pinching off clusters to encourage energy for new growth.
Post-Bloom Growth
Late spring through summerPlant produces new foliage and branch extension after flowers fade
Complete pruning and shaping by early summer. Continue regular watering. Reduce nitrogen fertilizer; shift to bloom-promoting formula (lower nitrogen) by mid-summer if desired.
Dormancy
Fall through early springShrub slows growth, hardens off, and prepares for winter cold
Taper watering in fall. Avoid late-season nitrogen fertilizer. Do not prune in late fall/early winter. Apply winter mulch in zones 4-5. Provide windbreak shelter in harsh climates.
