My hydrangea blossoms are very large and are turning brownish and dropping some petals. Should I cut off the blossoms to encourage new blooms? Otherwise the plants appear healthy.
Your hydrangeas look great! Yes, you should deadhead the spent flowers. It will help encourage the hydrangeas to re-bloom later this summer and into fall. In the fall, leave some of the dried flowers on to help give winter interest to the garden. Then, snip them off in early spring. My video gives tips on how and when to deadhead hydrangeas.
