I've basically been letting the grass in my back yard grow all spring. Cut some paths through so my small dogs could easily navigate and small patch for my senior dog.
Then I saw the foxtails I thought I had killed were back. I started cutting the grass so I could get better access to the foxtails and my allergies went crazy. Instant runny nose, eyes burning, etc.
This has really dampened my enthusiasm. (/rant
It's a work in progress.
