Dad didnt have a rotary hoe, so used the harrow. Angle the teeth back 2 notches from max, and if the ground starts cracking above the seed row, go harrow. You got 12 hours, don't waste them, if you don't use chemicals you need to be on top of the game right? ;) once the crack opens and green of the beans is showing, you ding them up bad with a harrow. Too early with the harrow and the weeds get a second chance. Timing is everything.
Organic beans wouldn't be so bad: don't know that I would be up to organic corn again in our short growing season. The last 5 years I've been planting corn in ground so cold the weeds haven't sprouted yet, would be hard to go back to waiting another 2-3 weeks before planting to wait out the weeds....
Got up to minus 1 degree today. At least the wind is down, was 12 below last nite after the 36 mph winds..... Spring will come won't it?
