astilbe flowers drying up, and skeletonized leaves
I planted two new astilbes last fall, and they came in huge and happy this spring. I don't remember the variety--I think it's supposed to have light pink flowers, and the leaves are darker green with reddish stems. They started putting up some flower stalks a few weeks ago, but today I noticed that the flower stalks have stayed small and most of them are dry and shriveled. Also, one of the plants has some skeletonized leaves (though most of the foliage is still healthy). I don't see any obvious bugs. The other astilbes in my yard are doing fine, putting up plenty of good flower stalks. Any ideas as to what is happening? Thanks.
