TACKLE TRICKY WEEDS

IN JULY, troublesome perennial weeds can take you by surprise. Creeping thistles, stinging nettles, ground elder and other horrors can multiply unseen at the backs of borders or behind tall summer plants. So it would be wise to carry out a little police work over the coming weeks. If you find sneaky weeds, dig them out. Root fragments left in the ground can send up new shoots, so check hidden areas regularly.
