Like most of you, last summer took a toll on lawns around here. When the snow fully comes off and things dry out, I expect to see a lot of patchy lawns due to death from drought and/or disease. Also expect to get some spring slice seed calls (normally don't get hardly any). Conditions wise, when is the best time to slice up an existing lawn? Talking northern lawns here, with a per rye/KBG mix. What soil temp should be a starting point? My gut says, you want to do this work before the existing grass fully 'wakes up' so the seedlings have a better chance to make it and not get choked out. Around there, that timing would be late April/very early May. Thoughts?
