My lawn is terrible. Right now all the crabgrass is dead and brown and it just shows exactly how terrible it is. I have no idea what kind of grasses are in it. I can tell you for sure it isn't really just one or two types. In reality I want to just want to kill it all and start over with good grass. I have several questions. 1: What is the best time to kill and reseed it all? 2: I have a bit of shade in my side yard which is separated from the rest of the lawn by the driveway. What type of seed would work well there? 3: The rest of my yard is fairly flat with just the front being a hill and it has little to no shade what seed would work well there? 4: What is the best way to kill it all off? I'm thinking roundup. I've seen lawns in my area done in a similar way. They killed off all the grass this fall with some kind of herbicide and left the dead grass. Then they must have slit seeded it and now it came up and it is beautiful. Before someone suggests to me that I should get a soil sample I will tell you now. I have already gotten a soil sample and I've added everything it told me to. I plan on getting another and having it tested again to make sure everything I put down worked correctly. My PH was pretty high for my area. I put down a bit of lime and 25-5-10 fert like the test results said to. Any help is greatly appreciated. By the way: Call an LCO is not a good answer. I'm trying to learn how to do this stuff myself so I can start a new part of my business doing work like this.
