I have 3 of the Original Endless Summer hydrangeas planted. 2 of the plants have blooms that have turned brown and completely dried out. Should I prune these off and how should I do that?
To improve the appearance of the hydrangeas, you can deadhead, trim off, the brown flowers. You run the risk of trimming off next year’s flower buds if you heavily prune the shrub now. If necessary, it’s best to prune in early spring.
