Hydrangeas: The Ultimate Guide To Achieving Optimal Growth Through Sunlight Optimization
Hydrangeas prefer partial shade, receiving around 4-6 hours of sunlight daily. Direct sunlight can scorch leaves, while excessive shade can lead to fewer blooms. Filtered sunlight through trees or structures can provide the ideal balance for healthy growth. Providing some morning sun can promote vibrant flower colors, while afternoon shade protects from intense heat.
