Need help on approach and grass/weed types?
My mother moved into a house over the winter and I am now trying to help with her lawn (if you want to call it that.) It is quite a mess and I am not sure where to start. I was thinking to dethatch, aerate, and overseed first but since it has a ton of dandelions and other weeds I am wondering if I should treat the weeds first. If I treat the weeds I will have to wait about 3 weeks to seed which I am wondering if that will be too late. Most things I have read say to seed in early spring, if you can�t wait until fall. I realize I should get a soil test as well which I will definitely do either now of over the summer but just wanted to get started on something this weekend.
I would love some advice on what your approach would be as well as what type of grass and weeds you see. Obviously there is a dead tree that needs to be removed as well. We live in St. Louis. Any help would be appreciated.
