So I screwed up bigtime and didn't foresee the onslaught of the billions of cottonwood seeds that have descended upon my backyard and garden. I should have put some netting over my boxes for a few weeks but now I've got little sprouts popping up all over them and as of now, the back looks like its been snowng. I've never seen it so bad in the 12 years I've lived here.
I scooped out a bunch of them along w/ a thin layer of soil but is there a way to defeat them more easily ? As they seem to sprout with nearly no dirt covering them, can I put an inch or so of compost or mulch on top to smother them ? Or do I have to keep skimming them off all summer ??
