Pre-Flowering
2-3 weeksFoliage becomes more compact and dense; flower buds begin forming at branch tips
Maintain minimal watering; avoid high-nitrogen fertilizer which promotes foliage over flowers; ensure full sun exposure
Flowering
4-6 weeks (spring), occasional in fallDense clusters of tiny white flowers cover the plant in spring, sometimes with minor reblooms in fall
Deadhead spent flowers to encourage additional blooms and maintain shape; do not fertilize during flowering
Post-Flowering/Dormancy
6-8 monthsFoliage remains evergreen throughout winter; plant enters semi-dormant state in cold climates
