basically, I have had constructions and my lawn is killed. I hired someone around may to fix the problem and put new lawn for me. I am not sure what steps he did or didn't, But not only almost no grass grew there, but now it is filled with weeds, and feels bumpy and I can see small and big rocks. I didn't see that originally, because he covered it with straw and told us not to walk on it, just water it. I do not know what do I need to do now. I used grass and weed killer to kill whatever it is there and start new. but the more I read online the more I get confused. should I use power rake to remove the old grass and weeds, will it remove them all? should I till the yard, or not necessary? do I need to remove all small and big rocks and if yes, how? how do I make it even? I will be in and out of town till mid October, is it okay to plant the grass then? should I have the lawn ready and then plant the grass as soon as I come back on October, so I know I will be there to water it? if anyone can help guide me of what to do, I will really appreciate it.
As A Landscaper myself, I dislike seeding before Winter. Preferably Lay down Bermuda sod if your in A sunny semi tropical region. Early spring would be best. Water the sod daily in the morning in the first week, every other day 2nd week, twice weekly after that depending on the temperature ( any thing over 95 Fahrenheit should be done daily. Fescue grass for milder cooler temperatures and especially for shady conditions. Seed the fescue in the spring fertilize same time be sure to water it in same day. ( fescue does not do well in High temp direct sunlight ) you might try Rye by seed if your trying to get the best of both world. ( Warning Bermuda is an aggressive growing grass that can spill over in other areas if not kept in check .
