Post-Bloom Growth
May-JulyPlant redirects energy to foliage and branch development; new leaf flushes appear
Light pruning to maintain shape. Resume fertilizing with dilute rhododendron fertilizer if desired. Maintain even soil moisture.
Dormancy & Bud Formation
August-MarchGrowth slows; flower buds form in terminal positions for next year's bloom; foliage hardens
Reduce watering frequency but maintain adequate moisture. No fertilizing. Protect from harsh winter winds in colder zones with burlap screens.
