Like us, you might mulch your garden walkway with grass clippings or leaves. When it's hot, the soil will dry and crack. When it rains muddy, slippery and even dangerous to walk on. You can't win! So cover your paths with shredded bark, which can be added to the soil as humus in the fall. it looks great and makes walking around the garden a lot less muddy. We got ours when Dumb and Dumber came to cut down our tree. They left a mess (I mean, shredded bark) that we plopped into our garden path.
