I was recently inspired by a gardener profiled in the April/May issue of Organic Gardening magazine. In the interview, gardener Dallas Hays of Lewiston, Idaho talks about making his own fish fertilizer (good for nitrogen) “..using a blender and squawfish from a nearby lake.” He also makes his own potting mix and substitutes ground up loofah that he grows himself as a substitute for peat moss. In the same mix he replaces perlite with corncobs run through a cornmeal grinder.
I love it when people take it upon themselves to go outside the usual and try new and crazy homemade substitutes in the garden. Dallas, if you are reading this, you rule!
