About half a dozen of my recently planted Petunias have severe slug damage, I've dug them up and potted them up and brought them inside in the hope that they'll recover. However, bearing in mind that some of them are, quite literally, just a few stalks with no leavesor buds is it likely that they have had it? Should I feed them with anything to help them recover? No harm in trying to resurrect them of course, I'm just curious how readily Petunias can recover from such severe damage if cared for. If they do recover I plan to put them in pots in a different location and not back into the flowerbed.
