Pre-emergent granules stuck to Barberries - Leaves now gone?
I hadn't realized it, but in spreading Surflan (pre-emergent weed screen granules) this summer, I'd gotten a bit on my Royal Burgundy Barberries. Now, the leaves have not grown and the shrubs--despite trying my best to brush it off--look almost as if they're dead.
What should I do about this? I hoped they would be okay if I trimmed them back in late Winter.
Thanks for any advice!
