I have talked to my customer last month about reseeding the back and there is a huge spot in the front that has to be seeded. There lawn isn't treated and about 5-10% of the lawn is burnt still over the harsh drought we had. They never watered there lawns as well. Now they care about there lawn (rolling my eye's). I know the latest to grow grass and have it successfully survive the winter is to grow no later then a week or two after labor day. Now she wants to give me the go. I am just worried it's kind of late. The temps say the lowest will be in the upper 40's and around day will be 50's -60's for the next 10 days. But we all know how the weather is wrong.
