I want to put grass seed down on a large patch in my yard. Looking at the box stores online, there are dozens of different 'products' some come with dirt and fertilizer mixed in, or water retention chemicals, and some for shade, some grasses that are for fast growth and then die. It makes it confusing. My patch gets shade and sun. My question is, what grass seeds have you used that sprouted fine and would recommend? I would need a smaller sized bag, not 20 pounds of seed.
