They will probably not recover. How crappy!
At least cut off any distorted growth, try washing the plant off. But
don't hold your breath, I'm sorry. Plus, I don't think you want to
eat anything that plant produces now....
Once my ex-husband got crazy with the weed n' feed, sprayed all the
plants in the yard. It was not pretty. I went on a spree at my
favorite nursery, but it didn't make up for losing my babies.
Go get some crazy fun heirlooms or something. Maybe that will take the
sting off your loss.
