Is afternoon sun OK for hydrangeas?
Hydrangeas grow best in morning sun. Direct sun in the afternoon can burn the large, soft leaves. For this reason, a location where the plant gets some sun in the morning and none the rest of the day is best, but late afternoon sun probably won’t hurt the hydrangea if it isn’t in direct sunlight.
How do I know if my hydrangea is overwatered?
Root rot caused by overwatering produces yellowed leaves rather than dark, rich green leaves. An overwatered plant may shed leaves prematurely, or there may appear to be an overgrowth of green foliage due to stunted flower growth. Leaves may also grow too large, obscuring opportunities for budding.
