I had the same problem some years ago and the only solution for me was to fence the garden securely, using "stock" netting along the post & rail fencing and hedges. It was quite straightforward to fix the netting to the post & rail, and for the hedges I had short posts put in, as close as possible to the hedge itself, and the netting was fixed to them. Now it's almost impossible to see the netting there, as the hedging has grown through to some extent. Badgers are surprisingly strong, so tough fencing/netting is what's needed.
In case you're wondering what I mean by "stock" netting, it's the sort which comes in a roll and is made from strong wire, and the spaces are square/rectangular, rather than the "chicken wire" hexagons. The way to attach it is to fix the "squares" part at the top and the "rectangles" at the bottom. If you can visit an agricultural supplies place, you'd be able to see it - or ask a fencing contractor to show you.
