I've been reading other people's veg-growing blogs lately, and I wish I'd started sooner. It's very gratifying to know that I'm not the only one struggling with the dreadful, unreliable British weather, erratic seed germination, etc!
Particular favourites at the moment are Vegmonkey, for showing how much can be done in a small space, and Soilman for his self-deprecating humour :)
