Not enough info. Can we see a photo? What variety of Hydrangea? What is the light like (full sun, morning only sun, full shade, dappled shade . . . ?) Are the leaves wilting also? Where are you (nearest large city and what zone?) Have you stuck your finger down into the rootball to see if it is moist or soggy or dry?

If you want to add location and zone info to your profile so that it will post automatically on GW posts so we don't have to ask, here's how:

Go to Your Houzz in the upper right of every page, click Edit Profile, and on the left side click advanced settings. Well down the advanced settings page is a blank labeled Climate Zone for Garden Forums along with a link to find your zone.

If you add info on your state or the nearest large city you will get even better information since zone only relates to average coldest winter temperatures.

Then return to the top of the page and click Done Editing.

these are two twist n shout lacecap hydrangeas bought at a local nursery. they were in a two gallon pots in full bloom. Some of the leaves don't look so good but most of the blooms are dead or dying. They were planted exactly are stated on the tags and watered well. Shredded oak leaves as mulch. Are the plants diseased?

The plants are possibly over-watered or getting too much sun initially. The blooms do not last all Summer either; most last about a month or so and then tend to look aged or wilted.

How long ago did you buy these and how much of a gap was there in between that and planting?

I bought the plants on May 7 and because of cold rainy weather I did not plant them until May 20. I'm sure they were in pots much longer than that. Should I cut off the dead flowers and see what happens also the bad leaves? I up loaded pictures put where they are I have no idea.

Pictures would definitely help...
