A tidy garden is a sterile one. Leave some stinging nettles for our most popular butterflies for whom it is their only food (Peacock, Small Tortishell, Red Admiral, and Painted Lady) and several moths too.. And should you be lucky enough to have wild thistles with their magnificent heads, they are food for paineted lady butterflies and later in the year their dried stems provide protection for over wintering insects and their larvae. Add a few rotting logs under a bush and see what happens. My neighbours lawns are nicely trimmed and as interesting as a wall of drying paint!
It is hardly a wildlife haven but a couple of bees and a small white and a skipper butterflies on the chickory.
