Depends on: 1) soil (more organic matter or moisture & there's massive variations there) 2) Hiigher seeding rate helps in addition to adding an annual clover or possibly some oats.... Personally, I go heavy on a variety of clovers & do include an annual for variety of reasons - one being - annuals grow quicker & choke out weeds & deer love em. If I drill - not as critical. Go tear up a weedy seed bed mess.... Better go really heavy & use annual and maybe oats. 3) WEATHER. That's what gives ANY situation flexibility.... "hey, I planted beans July 4 & they did 50 bushels" VS "I planted beans May 15, didn't rain for 2 months & I got NOTHING!!! Same with clover.... Good weather, plenty of rain without scorching temps & you control weeds - no issue. A June & July like last year??? OUCH! Give it a whirl if you can handle the risks. Could be great, could bomb. 2 Variables above you can control, 1 you cannot.
