OK I have about an acre of land that has been weed infested and cheat grass infested for years. I finally got around to tilling it today. The weeds and cheat have been tilled under and the land raked smooth. My question is what now. I know there is a million weeds and cheat waiting to come up. Do I plant now or kill the weeds when they come up and then plant this fall. I am not in a hurry. The acre has been weed infested for 10 years, I just want to plant a field grass that grows in the spring then goes dorment in the summer ( I live in eastern washington and it gets hot and dry summmers). The grass is only being planted to controll the weeds. I plan on mowing it once a year.
