Q: I was wondering when we could start lawn work in our area? Is there a rule of thumb when we can start mowing? Minnesota. Thanks.

Ideally, the grass should reach it's maximum mowing height first (ie. bluegrass 3") and then mown, using the 1/3 rule for removal. In practice, it probably doesn't make that much difference. It's nice to get out and get that first mowing in to get things shaped up, as well as cleaning up all the accumulated debris from the winter
