This week we find out how to help our beloved prickly friends, as RHS Senior Wildlife Specialist Helen Bostock explains the threats to hedgehogs, and what we can do as gardeners to support them. Next we head indoors to find out how tailoring your potting mix can give your houseplants a new lease of life, with the lovely folks at Soil Ninja. Finally, if you’re looking for an autumn project, why not build some raised beds? We glean some expert advice on how to go about this, with RHS horticulturist Peter Adams.
