Hello everyone, new homeowner here. I have been stalking this forum for a long time and have learned ALOT already. So here's what we got.
After moving in last summer we suffered a long and hot drought in the summer months. The lawn was already thin and stressed and this put it over the top. The lawn suffered and the result were numerous dead spots. The following spring invited many weeds, mainly creeping Charlie and violets. I spent most of he spring spraying and handweeding which has helped immensely. I am now suffering from complete bare patches as the Charlie choked out much of the grass. I have been feeding with Milorganite, mulch mowing, and watering deep and infrequently. This has really helped my existing lawn but it's still very thin and non existent in select spots.
I would really like to overseed but not sure what I should be doing now. In the very thin spots should I just kill everything and start over? Also will overseedig the thin spots help me fend off some of the Charlie and violets or does each and everyone need to be killed before Overseeding. I have about .65 acres so I will prob take two years to get this job done. My grass is a mix of fescue and zoysia. Selecting a grass to overseed with is a whole other issue. Any help or insight into my dilemma would be much appreciated. Thanks so much in advance.
