I have these huge iris beds. I put corn gluten on top as the pre-emergent and the magpies ate it! What else will work to use as a topping? HELP!!!!!!!!
I use Ronstar that I get at the farm co op. Expensive here at 85.00 for 50# but really helps alot more than the corn glutten plus birds, and rabbits ate that and the dear beloved deer that can tell a 100.00 from a 5.00 daylily in a flash.
