Buckwheat in Okla: How's yours?
I really had to work the soil. It doesn't like compaction. I reseeded in a few areas. I'm having decent luck with it. I love how fast it grows and how easy it is to pull or kill. These are making some nice fall beds. I broad cast several pounds all over the place. It didn't come up. But the recent cool weather and a bit of moisture has caused it to germinate in many areas.
It's not the best root system for clay soil, but it's doing decent at suppressing grass growth in recently disturbed yard area. I can see why three successive plantings for new areas are recommended.
I have been extremely gratified to see predator wasps chowing down on the blossoms.
