Sunn Hemp 5#

Sunn Hemp cover crop legume seed is a warm season legume, upright and quick in its growth habit. Sunn Hemp needs 60°F soil temps before it can be planted and will kill at the first signs of frost. Higher seeding rates of Sunn hemp will help with weed suppression.
• Produces significant amounts of nitrogen in 60 days depending on conditions
• Tolerant of dry conditions and low fertility
• Can add up to 5,000+ lbs. of biomass per acre in 7-8 weeks
• Research has shown levels of nematode suppression (root knot, borrowing)
