creeping buttercup, galloping bindweed, giant dandilions,rampaging ground elder, spiteful stinging neetles, choking cooch grass and that's not the end of it!!!!!! massive Brambles, leave the garden just a short while,you know things like the weather not being able to get out on the heavy clay and you are done for, so friends keep at it or your lovely gardens will end up like a jungle. Some one who knows, from experiance.
