Hey guys, I've been searching for different advice on the forum for a couple of months and you guys are great!!! By the way I'm in L.A. California and been doing yard maintenance/landscaping for 2 years. This is my first post and I'd like some advice on 2 jobs: 1. Renovating lawn: customer has about 2,500 square ft tall "marathon" brand fescue (which is the most common grass in LA, along with st. augustine/bermuda/ryegrass). It has been overtaken by ugly weeds and they basically want to get rid of it and throw some seed. What's the best way to approach this? Here is my plan as of now: -use roundup to kill it, use rakes two weeks later when its dead to remove all dead grass and weeds, aerate 3 times over and then seed. Am i going to be fine just using some regular metal rakes to drag out the grass after the roundup has killed it? I've read that I could use a rototiller instead of the aerator before seeding, this will probably bring all the roots of the grass and weeds up to the surface and cause a lot more labor removing this debris with rakes right? So will I be fine if I just rake as much as I can from the surface after the roundup and then aerate or should I rototill? 2. This is for a bunch of yards in an enclosed community. Tall Fescue on all lawns. The weeds are not as bad but they'd like me to get rid of them and overseed SOME areas where the grass is dying/yellow. Should I use post-em herbicide and spray the weeds and then overseed?? Do I have to wait weeks/months after using the post-em before reseeding the bad areas again? Keep in mind that it is like a bunch of 2,000sq ft lawns, probably like 25. What is the best/most effective way to do this? Is weedn'feed and then overseeding a better option?
