Psandu,

I planted an acre of flowers this year, but it's been a real bust. I plowed, disked, used Dual Magnum as pre-emergent. I used the smallest seed plate I had but not small enough, so did have way too many plants. Came up clean, stayed pretty clean to 18", cultivated. Plants matured, heads were admitedly small but plenty of seed. I think what killed me is just before maturity in August, I got a ton of grass. Relatively short, 12" or less, and not even all that thick, but enough apparently so the birds didn't want to go in. I've mowed and disked several passes to create some bare ground, and still no birds. I live in good dove country so this has been frustrating. Do you use a grass control herbicide and if so, when do you apply and at what rate. Treflan?
