If you live on Thornton Heath Road, you probably know the rhythm of a London garden: a burst of growth after rain, a hedge that seems to stretch overnight, and a lawn that can look tired by Friday if it's been left alone too long.

If you live or work close to Woodside tram stop, you probably know the feeling: the garden looks fine from a distance, but the hedge is getting shaggy, the lawn is patchy, and the weekend disappears before you've done half of it.
