I took a new cust that has small back yard with bermuda. old lco did not overseed it last yr. cust wants it done so she will have something in the winter, I have never done it but have read up on it. in so cal where temp is still hitting high 80's low 90's. So my question is when is the best time to do this? I read when the outside temp is in low 80's during day and 50's at night? the way its been that will be dec. Any help would be greatly appreciated!
