Hey guys I want to dethatch, core aerate and overseed this year but have never done it on my property and the previous homeowner didn't do anything. Any advice on when and how? I have a dethatch and core aerator. Also any advice on which seed to use? I can get the sun/shade mix from scotts at my local big box. I have a few different types of grass in my yard.... Some looks like wavy dog fur which I hate. Also have zoysia on about 1/4 of the property. I'm not sure if overseeding over zoysia is just throwing money away. But I do need to dethatch and aerate for sure this year. Lots of thatch on the zoysia area and lots of bare spots with compacted soil. So any advice on when and how to overseed would be great! Thanks!
