I had a No Mow Spring in my backyard. The yard was cut down less than a week ago because I could not go out there for 10 minutes without my eyes starting to hurt. It was worse if I tried to kill the invasives. My area has had a terrible allergy season.
It is mostly non-native grass mixed in with invasives. There is ONE native plant I put in. Baby steps. I will add a few more natives during planting season.
