I'm just not sure yet what it will look like when in full bloom. From what I've read 80% of it's nitrogen is in the nodules on the roots until it starts to produce seeds. Then the nitrogen is pulled up the stem and stored in the seed. I'm hoping I can cut it down soon enough to get a second crop 4-6 weeks before our first frost which is Oct 20. Then it can be left over the winter without producing seed and then tilled under in the spring.
