When planted in the spring, these varieties do not bloom but instead grow vigorously and help crowd out weeds. Rapeseed requires a firm, smooth seedbed that is free of weeds, heavy residue, and large clods. Seed may be drilled or broadcast. A seeding rate of 7-8 pounds per acre works well. Rapeseed is sensitive to broadleaf herbicide carryover.
Sulfur is necessary for rapeseed to produce nematicidal compounds.
Although most orchard soil is not deficient in sulfur, a soil test to test the availability of this element may be beneficial.
