I don't know your climate or your grass type, but in the UK it can be done pretty much anytime that temperatures are above 6C (42f- ish)... so you may have a bit of time in hand, if 'soon' is too pressing! haha

I'm going to have to wait until it's after the 4th. WE have a cookout and lot of people are on the grass.

The whole lawn may need help after that, then. Good luck!

Yeah. that's why i'm not to worried about it at the moment. :)
