Sunn hemp is a well known root knot nematode repellant but it will also help to prevent erosion, compaction, leaching of nutrients, and solarizing. Cut down above ground mass two weeks prior to planting your fall garden and lay the cuttings on top of beds to protect soil until planting. It will act as mulch and add fertility to the soil. One package will plant 2 3x6 beds or roughly 40 sq ft.

Good to start from seed in these months:

North Florida: April-August

Central Florida: March-September

South Florida: March-September
