Hello. I have a number of mophead hydrangeas (I do not know the variety) grown from cuttings that are about 18 months old. They have been in the greenhouse over winter, and I am about to plant them in the garden. Some seem to have grown quite tall. My question is, should I prune them to try to make them more bushy? I live in quite a windy spot near the sea. Is there any other advice I should know? Thanks for any help.
Pruning will be very beneficial to these trees, but you don't want to cut them completely back, since they only flower from old growth.

It's late March in No. Lower Michigan. My Hydrangea bush still has several dead flowers on it, is that normal? If not,what should I do? Thanks
After transplanting a mophead, will it bloom that same year or will it take 1-2 yrs b4 it will bloom?
Spring will be the best time for transplant. This will likely take a year or two before you see the first blooms. Here is an article that will offer more information: https://www.gardeningknowhow.com/ornamental/shrubs/hydrangea/mophead-hydrangea-care.htm
tiful purple lacecap. Tell me what happened? Many Thanks
The pH of the soil changed. This can change the bloom color.

I was wondering if it is unusual to have heads of lacecap on a mop head hydrangea.
The Lacecap and the Mophead are both H. macrophylla. The Lacecap is just a different variant of the Mophead, and it is not impossible for Mopheads to grow sterile flowers in the center.

Hello my mophead hydrangea only grew up from the bottom this year. It is high probably 5 feet by 6 feet. Great foliage only until late September. It started to bud out. Had one bloom. All the cluster are there. What should I do now. I live in IL. Do I cut it back it is so big. Actually all my hydrangeas did the same except the ones that bloom on new leaves and old leaves. Thanks please tell me how to treat these.
The mopheads bloom on old wood which means they form flower buds the previous season. That is what yours are doing. I definitely would not prune them or you will cut off next year's blooms.
Here is a rundown of how to prune the different types of hydrangeas.

y are quite lanky and tall and no blooms. How should I prune them this fall to promote blooms They are shoulder height now with very few blooms in the past two years. I don't know how to prune them. Should I cut way back to a low height or at certain points on the stems?
Mopheads can be pruned AFTER they bloom. It's too late now to prune because they already have formed buds for next spring. Here is more:
