The only problem with planting sunflowers is getting rid of them when you dont want them anymore. They seed out and keep reproducing forever. Im in west Texas and we have sunflowers everywhere. A hinderance for farmers but great for dove hunting. We farm and also have day hunters. We let a patches of sunflowers grow then jsut before hunting season we shread shooting lanes. Makes it perfect. Sunflowers are tough and hard to plow. Plant some and you wil find out.
