I wanted a cover crop to enrich our soil and to prevent erosion. I didn’t really have high hopes for the Sunn Hemp, but they’re growing like crazy. All we did was scatter seeds by hand, rake them in, give them a daily watering and they had germinated and sprouted up within 3 days. I’d wager 9 out of 10 of the seeds all sprouted. I am so happy with this purchase!
