I have established flower beds. How can I convert them to use mulch and such without digging up all my plants. I bought six bags of fish mulch (made in Alaska) and was going to scatter it on the beds before things began to come up as a start. Composting doesn't seem like a good idea here because it is so cold on average (60F) that I didn't think stuff would work up a good rot. But would do it if I knew it would work.
