There was just a couple pounds left over of the Sunn Hemp and although it was a couple years old, i just threw it on my garden spot and expected it to do nothing. HA! Not only did the seed sprout (it was not even inoculated) it thrived, then took over! Needless to say my garden production suffered, but i’m just gonna let it grow and see what it will do. It is not supposed to mature and make seed in our environment. Otherwise, it could become an invasive species and though it is not native to the US, it is being promoted as a deep rooted plant which will bring up minerals as well as provide some grazing when it is much younger. The stalks now are up to an inch in diameter and quite sturdy. I plan to chop them down and let them lay as a cover to the soil. The chickens will have opportunity to winter in the garden plot and they will scratch it around and maybe eat a few leaves all the while adding manure out the back end.
