Two weeks of over 100 degrees have just fried my astilbe. They bloomed so pretty. I have always enjoyed their plumbs after bloom, but now they look terrible! Can you cut these back without harm to next year? I thank you for any answers to this question. Lesley

Lesley, I've only grown astilibe one summer and don't know anything about them but I'd take a chance at cutting them back. What do you have to lose? Gardening is all about trial and error. I'm sure you'll get more responses from more experienced gardeners. Good Luck! Keep us informed how it turns out.

Lesley - I have many astilbe and extreme heat combined with lack of rain will cause their demise for this year. Cut them back, water them well (if possible) and any extra compost you can mulch them with would be most helpful to them.

Wow, Pirl, what a nice patch of astilbe.
And the lighting makes them look even more spectacular!
It's hard to believe my dried up clump could revive like that next year,
but I sure hope so!

It has happened often enough to various astilbe patches here. The first time I was sure they were gone forever but (happily) I was wrong. Dump on the cooled coffee grounds and chopped leaves and give it your leftover cooled coffee each day.

This patch seems to dry out fast even though it faces northeast and has the shade of the magnolia. I use the extra day old water from the birdbath on it to keep it happy.

Thanks, Scott. That photo was taken around 7:30 AM. At 4:30 in the afternoon it looks like the second photo posted here. It's in full hot sun all afternoon and doesn't miss a beat. (Lots of compost used at planting time).

Thanks everyone!!! I really appreciate your prompt answers to my fried astilbes. I will cut them back, add some compost and add cool coffee! All of this , I can do...I sure hope we get a break in this heat. My astilbes are not the only fried plants in my garden! Happy Gardening to all. Lesley

My Astilbes have been covered with coleus, I guess that will protect them. I have been watering every day, so I am hoping they will survive. Etelka
