OK. we tried several experiments this season, and I planted a strip of sunflowers out in the barley field where the planter had missed. These guys did very well. Huge heads, lots of seeds, now I just need to figure out how to hull them quickly. We did some oil seed sunflowers and some confection sunflowers. I think I will plant more next year if we are able to put these to use. Any suggestions for hulling easily?
