| For the Camano garden we buy cedar play chips specifically for mulching all plants, including herbaceous ones. Like them much better than bark or other smelly, crust-forming moldy mulches. For the other place we use free wood chips from an arborist. Not as clean and uniform as the purchased cedar play chips and very moldy (at first) but works great otherwise - except the time giant morning glory (Calystegia sepium) came with some. |
