The best way to help the hedgehogs that visit your garden is every night just before dust put out some dry hedgehog food for them & fresh water.
Any uneaten food should be removed in the morning to avoid them being eaten by cats or vermin and placed out again the next night with fresh food and water.

Feeding guide: Place Mr Johnson’s Wildlife Hedgehog food in a heavy shallow bowl in a quiet sheltered spot in the garden, this will provide hedgehogs with essential vitamins that will supplement their natural diet, especially in times of natural food shortage.

Ensure they have access to fresh drinking water in a shallow bowl at all times to help prevent them from becoming dehydrated.
