I did something this week that I’ve never done before as a gardener. I started a butterfly garden and planted all my plants in 9″ of mulch. Now this is not something that I’d recommend or normally even try, but the “maintenance” people had dumped a whole pile of mulch in this one area, the previous fall. Even though we tried to move some of it, it was just too much of a job for the time we had. I loosened up the mulch so my little helpers, 15 Brownies, could plant and then we just made a hole in the mulch, put in our plant and filled in with Miracle Potting Soil. We top-dressed the entire area with the remaining soil.
I’ll report in the fall how well this method works.
