Rough Stuff for Lawns

One of the real downsides of maintaining feeders--particularly those stocking sunflower seed--is that lawns can take a real beating. Sunflower seed hulls (and I think, safflower seed hulls as well) contain allelopaths which can eradicate whole sections of plants. My fescue is one of these. I replanted a significant section of my lawn last September and most of it, enduring flash downpours, drought, and sunflower seed hulls, is looking pretty beaten today. I'm going to have to get much more serious about solving this problem. Buy expensive hulled seed? find a means to catch or deflect hulls? realign the feeders so that the sunflower seeds fall into the mulched section? Lots to think about. For now, I mourn my deceased grass and prepare to reseed again next weekend.
