As the years pass, we find we want to empty the cans quickly and move on. Most plant species cannot handle this much nutrient at once. But there are a few that can. We call them the "poop beasts". Willow, cottonwood, poplar and bamboo. They will greedily gobble up as much as we can give them and then lick their plate clean.
