i've never planted it steve, so i'm wondering the same thing. i'll irrigate if i need to. i'm hoping sumac will mix in with it naturally, it's usually one of the first things to grow under power lines in our area.
dprater, i planted it under my power line. it's too close to the road to hunt and i'm ok with it coming back there. i was going to plant another three acre field to improve the soil, though. i'll rethink that now, thanks. maybe i'll plant a mix of clover in that field this winter. half of it's in sunflowers now and i'm going to plant the other half in grain sorghum next month.
