We're well into August and Monty is pleased to see that his hostas haven't even been nibbled. He believes that is down to him trying to grow healthy plants and give them the conditions that they will thrive in. This also has a lot to do with the balance of wildlife at Longmeadow, where there are slugs and snails but also lots of thrushes, blackbirds, hedgehogs and toads, frogs and beetles, all of which eat the slugs and snails which eat the hostas. Monty explains that you have prey and you have predators and you have a whole ecology that looks after itself. Nothing gets out of control. Everything is on a state of subtle balance, and if it is a balanced garden, then it'll be a beautiful healthy garden as well. Naturalist Simon King shows us the wildlife that depends on our gardens, we visit a small space designed as a haven for garden creatures. Carol Klein is first at Pilsdon Pen, which is one of the highest points in Dorset. It used to be the site of an Iron Age Fort but that has all gone now and all that remains is close cropped grassland full of wildflowers, and in amongst them is a tiny little flower - bird's foot trefoil, so-called because of the seedheads which are three pods arranged just like a bird's foot, and those pods tell you that they belong to the pea family. Probably the most celebrated member of the family is the sweet pea. Carol visits Forde Abbey in Dorset, where the walled garden is filled with sweet peas. She meets Alice Kennard who has masterminded the display there.
