I have a 3-year-old Tuff Stuff (a smaller Mountain Hydrangea). Until a week ago, the leaves were gorgeous green. But every year, they curl and turn black. It gets morning shade then sun in the afternoon. It's well drained and gets watered several times a week. I'm careful not to over water. And I've cleared all other plants away from it, thinking that may be an issue. I haven't added any fertilizer or other sprayed it.

I love the blooms but this happens every year. And the plant starts looking more dead than alive.

Thoughts on what this might be, before I chuck it at the end of the season and try something different?

Thanks in advance.

I'm afraid I am not of much help with Hydrangeas.

Does it come back from the roots in fall when it cools down?

Have you ever tied it to the temperature? It sounds like a heat issue.

Where are you located exactly? When did it leaf out for you? Do you have any pictures?

Probably different but I have Oakleaf Hydrangeas. They get some morning sun but are in the shade the rest of the day. And they face north. Had a bit of a heat wave lately and the blooms are starting to look floppy. Need water! My newest Oakleaf (purchased at an 'after the tornado hit' sale) isn't in the ground yet. I've been moving it around and at one point about a month ago some very strong winds kept blowing it over. I found a temporary spot for it that's sorta sheltered but faces west. I thought I'd killed it as the leaves were shriveled up and it looked awful. Gave it a major watering and it seems to have recovered. I need to find a place to plant it because I know it will be happier. For now I need to keep it shaded and not let it dry out. But enough about me. I need to look in the database to see what kind of hydrangea you have.

EDITED: Saw some very pretty pictures of Tuff Stuff hydrangeas in our database. Says the max. recommended zone is 9b. So you might be kinda on the edge of it's happy place. (Did I just sat that?) So anyway, if you could post a few pictures it would really help.

So tell us more about your hydrangea. You're right not too fertilize it when it's stressed. Maybe it's getting too much afternoon sun. If you've kept it alive for 3 years, then there's something it likes and something it just plain old doesn't like. Does it look healthy the rest of the year when the weather might be cooler?
