Hello everyone, first post here.. I recently purchased a new home, which didnt have any grass at the time. Part of the purchase and sales agreement was that they would put down hydroseed. This was done around April/May, cant remember exactly. Since then, we have had grass along with crabgrass and many weeds. The grass is not very thick at all, and there are a few areas that are dirty only, seems the seed didnt pick up. Yesterday finally I went to Home Depot to pick up something to fight the weeds and crabgrass. The product is called 'Ortho Weed B Gon'. I followed the directions and used a spray bottle connected to my water hose to apply the product to my whole lawn. This morning I can see the weeds are flopped over and dying, but the crabgrass looks healthy as ever. So now to my questions.. What is a quality product that can get rid of the Crabgrass, something available in Home Depot or a similar store. After the crabgrass is gone, what fertilizer should I use to help the grass grow? Something that can be applies easily connecting a sprayer to a hose would be best. Thanks for the help!! CLIFFNOTES: New grass has weeds + crabgrass, how do I get rid of them and then get the normal grass to grow in nice. Which products should I use?
