Create a hibernation place for your garden wildlife. Many invertebrates will make use of a pile of logs. Hedgehogs may use a ‘hedgehog hibernation house’-make it big enough about 15ins square, stuff it with leaves & leave a few windfall fruits & a flat, shallow plant saucer of water nearby. Stack a few old logs around the hibernation house and wait. Hedgehogs forage about 1 mile every night and they need access to your garden, they can’t fly so make a 6″ square ‘hog hole’ in your solid boundaries to link your plot to the wider landscape.
