About Iron Clay Cowpeas

Warm-season legume for summer protein, which is the season most food plot planning ignores. Antler growth and lactation both happen in summer, and a property with nothing green in July is not holding deer regardless of what it grows in October. Very high protein, very palatable, and nitrogen fixing. Drought tolerant once away. The problem is that deer love them from the moment they emerge, and a small plot can be eaten to the stem before the plants ever canopy. An acre is a realistic minimum and two is safer. Many people cage a section or run a temporary electric wire for the first six weeks to let the crop establish, then drop it. Broadcast at 50 to 80 lb per acre. Warm soil is essential, so wait until well after last frost.

Common questions about Iron Clay Cowpeas

What is the seeding rate for Iron Clay Cowpeas?
Broadcast 50 to 80 lb per acre. Drilled rates run roughly a third lower. Soil test before buying seed, because pH matters more to the outcome than the rate does.
When should I plant Iron Clay Cowpeas?
Late spring into early summer, once soil is warm. It is a warm-season crop and needs soil that has genuinely warmed, not just a frost-free date on a calendar.
How big does a Iron Clay Cowpeas plot need to be?
About 1 acre as a realistic floor. Below that, deer graze the crop faster than it establishes and you get bare ground instead of forage. Local deer density moves this number more than anything else.
Do deer actually eat Iron Clay Cowpeas?
Frequently Severely Damaged on the Rutgers scale, which measures how heavily deer damage a plant. On an ornamental that is a warning. On a food plot crop it is the specification.
What hardiness zones does Iron Clay Cowpeas grow in?
Iron Clay Cowpeas is hardy in USDA zones 6 to 11. Outside that range it will either not survive winter or will struggle with summer heat.
How big does Iron Clay Cowpeas get?
Mature height is roughly 60–120 in. Growth rate is fast.
