Know before you buy
Winter killing means the plant will naturally die off when temperatures drop consistently below freezing. This saves you the labor of manually tilling or pulling the crop in the spring, as the residue will decompose on its own.
The Nitro Radish produces a deep, powerful taproot that acts like a biological drill. As it grows, it physically breaks through dense or compacted soil layers, improving aeration and water drainage for your future garden beds.
Nitro Radish is specifically designed as a fall cover crop. Planting it in the fall allows it to establish during the cooler months and complete its cycle before the ground freezes, which is essential for its soil-improving benefits.
Because it winter kills, you generally don't need to do anything. Once the ground thaws, you can simply plant directly into the decomposing residue or lightly rake it into the top layer of soil.
The recommended seeding rate is 1/2 lb. per 1,000 square feet. For larger areas, you should use approximately 2 lbs. per acre when broadcasting.
Yes, the Nitro Radish acts as a natural bio-fumigant and grows quickly to shade the soil surface. This combination helps suppress weed germination and growth during the off-season.
