If you’ve got a wildlife pond, make sure wildlife can get out of it if they fall in/venture in – give them a ramp to use. Hedgehogs swim well but they can’t climb out easily.
Let a corner of your garden grow messy – let plants and weeds grow (hurrah, no weeding!) They can tuck into the insects there – bettles, slugs and caterpillars will go down a treat. And give them something to eat – you can buy food for hedgehogs as an extra treat – meaty cat and dog food can also be served and they can nibble on cat biscuits as well.
Put a pile of logs in a corner for them to enjoy. They can rest there or hibernate. Plus log piles are good for encouraging insects which the hedgehogs can eat.
