I had new astilbes planted last July; they looked pretty feeble from the get-go, and almost died but after some careful watering and pruning, they revived and at least were small green leafy plants. After the first freeze, they totally went brown and all the leaves fell off, and they just look like crumpled dead brown stems now. Are they dead for good or as of April should they be showing at least some signs of regrowth? They look dead to me.
