I do, sometimes....kills insects, destroys the left over fugal spores (leaf spot), and I think it helps with some weed seeds, as well. The one bed I "burnt" last fall had the least problem with leaf spot this year, but, it also was the bed that was dug, and reset this year...so maybe the leaf spot just hadn't really "kicked in" yet?! I think this fall I'll burn again, at least some of the areas...the re bloomer bed needs dug and divided next year, and has a terrible leaf spot trouble this year...so I'm thinking I'll burn it off, for sure.................Arlyn
