I have peas in my greenhouse (about an inch high so giving them a few more days before transplanting) and also some sown directly which are a bit smaller, but seem to have just a stalk and no foliage....have they been got at by a pest and if so how do I protect them? Or are they jsut growing that way? I know this sounds daft, but I have tried to net them, but can't work out how the hell to do it and none of my neighbouring plots have bothered?!
