Greetings, I live in central Indiana and I'm trying to come up with a fert/re-seed plan that makes some sense for me and my little 8,000 sq. ft' (established 4 yrs. ago) lawn. But first, please know I'm 'just a homeowner' who enjoys DIY when it comes to making my lawn look good. I guess it's a self-satisfaction thing. However, I need some advice. While I know it's a bit early to judge, vast majority of my lawn (perennial rye / kbg) seems to have survived last summer's drought with minimal damage...thanks to my irrigation system and lesco fert plan/material. I do, however, have some relatively small spot repairing (re-seeding) to do where I don't think the grass survived...in part, due to fungus. Other than the isolated damaged areas, my lawn is quite thick with about 15% (spotty areas) needing to be thickened. Over the past 2-3 yrs, I have had very little broadleaf weed problems (spot treated w/speed zone) and zero crabgrass. So, I'm toying with the idea of skipping my spring pre-m ap's (2 ap's of 19-0-11 w/dimension) so I can grow some new grass this Spring. Here's my dilemma. My neighbor's entire lawn (about 3,500 sq/ft. in the front only) is mostly trash. Weeds, crabgrass, and toasted due to neglect. Last summer's drought just smoked most of what little (15% ?) 'good grass'e grass they had and encouraged huge broadleaf growth. It really needs a complete kill and renovation/re-seeking and'm the lucky guy elected to fix it. While I know Fall is a better time to do it, I'd really like to do the front yard only THIS SPRING, otherwise, it's another 1/2 year of ugly-ness...weeds entering my nice lawn, etc. It's a total waste of time and material $$$ to apply fert/broadleaf/crabgrass control. Here's my thought: Forget about the spring pre-m (dimension) on MY lawn so I can re-seed the areas (or even the entire lawn) needing thickened/repair. Somehow, I'll deal with any crabgrass that may find a place to grow. If I go forward with this approach, I would like your thoughts on a good fert/weed control plan in the absence of my spring pre-m/feedings AND given the new grass I'm trying to grow. As for my NEIGHBOR'S lawn, I'd like to kill it with something (round-up) and slice seed. However, given all the weeds (left-over from last year), I'm almost afraid I'll need to till it order to prepare a good 'seed bed'...but, there's no way I'll have the time/energy. I know I'll have a 'boat load' of weeds/crabgrass to deal with since they will have a perfect breeding ground...but I'm hopeful I'll produce a good stand of new grass along with it. So, my question is, how/when/what is my best approach to getting this entire job done THIS SPRING? Timing? Materials? Thanks for your help!!!
