Description

Sunn hemp is a summer annual tropical erect shrubby branched legume growing 3 to 9 feet high with bright green simple, elliptical leaves. It has a well-developed root system, with a strong taproot and good drought tolerance, greatly suppresses weeds. Used as a cover crop, food plot and soil builder, sunn hemp can improve soil properties, reduce soil erosion, conserve soil water, provide biomass and nitrogen and recycle plant nutrients from the subsoil to the topsoil. The leaves of sunn hemp are 30 % protein and are consumed by deer. Sunn hemp will adapt to a wide range of soils and performs better on poor sandy soils than most crops, grows best on well-drained soils with a pH from 5.0 to 7.5.

Frequently Asked Questions About Our Products

What is the recommended seeding rate and planting depth?
  • Planting Depth: Plant seeds 1/4 to 1/2 inch deep into a finely prepared, firm seedbed to ensure proper soil-to-seed contact.

  • Seeding Rate: Broadcast or drill at 10–12 lbs per acre for pure stands, or 4–6 lbs per acre when incorporating into forage or pasture mixes

  • Ideal pH: Thrives best in soils with a pH ranging from 6.0 to 7.0.

  • Soil & Fertility: Prefers well-drained to moderately drained soils rich in phosphorus and potassium. Limit heavy nitrogen applications to prevent weed competition.

  • Nitrogen Fixation: Pre-inoculation with host-specific Rhizobium bacteria promotes natural nitrogen fixation, cutting down on synthetic fertilizer costs.

  • Protection & Stand Establishment: The protective coating guards young seedlings against early moisture stress and soil-borne diseases for more uniform germination.

  • Spring Window: Plant from late March through May once soil temperatures reach 50°F.

  • Late Summer / Frost Seeding: A secondary window opens from August through early September. You can also frost-seed by broadcasting onto frozen ground in late winter (February–March).

  • Harvest Timing: Cut for hay or graze at 10–12% bloom to maximize digestibility and crude protein levels.

  • Overwintering: Allow a 4-to-6-week recovery period prior to the first hard autumn frost so plants can store root reserves for winter survival.
