Interesting re the blight, it certainly looks like blight and all the tomatoes have got it too even in the tunnel. I spray every year before it gets going but I guess that all the rain is washing it off outdoors as soon as I put it on! I don't normally grow many earlies and prefer the Sarpo blight free range as they always do so well here without needing any spraying (except once for the colorado beetle)so yes, the rocket especially has died down more than the Charlotte you could be right about that.
Critters? we had rats, there were also Coypue (sp?) near the lake last year. The cats catch various voles and mice and I once found a dead stoat/weazel. Thats about it for wildlife around here apart from wild boar and deer. Never seen a fox or squirrel, badger. all around us are huge flat fields of Rape, sunflowers and feed maize, hardly any hedges or cover. We have two dogs, good at chasing anything big away. a large black lab/beucheron cross and a little Pyrenean Sheepdog Ella who has quite a terrier like determination to dig up moles, mice etc although she has never eaten a mole.
I better go and find the rat poison and bait station.......
EDIT I just found on Google that voles can make that kind of teeth marks and often eat potatoes underground.
Does anyone know how to trap/poison a vole? my cats don't go as far as the veg garden, they prefer the easy win of mice and spiders in the old attic!
