Last September I graded, tilled, added potash, phosphorous, and nitrogen to prepare the soil around our house for new seed. I then seeded turf-type tall fescue (Hound Dog) at 10-lbs/1000 sq ft. It exceeded my expectations and turned out quite nice. The yard is about 3 acres. I did notice crabgrass here and there toward the end of the season poking through. Due to the size of the yard, what pre-emergent herbicide would you use this coming spring to eliminate crabgrass? Im located in Eastern Kansas BTW. Another question, currently on each side of our 800 driveway there is prairie grass, which we have just mowed in the past. This is probably totals about 2 acres. This grass is a mixture of prairie, fescue, foxtail, crabgrass, and clover. I have fertilized this in the fall with 18-46-0 in the past. The fescue is slowly creeping outward and thickening. If I wanted to thicken the fescue by overseeding, what should I do to prepare? If Im not going to be able to water it, should I consider overseeding this spring rather than next fall? Would an application of 2-4-D help? I figured Id core-aerate, fertilize, and sow 5-lbs/1000 sq ft. What can I do to eliminate the crabgrass, foxtail, and clover without starting over by killing everything tilling? The first picture is my stand of fescue and the second is the grass mix thats along the driveway. Thanks!
