Growing Tips
Plant 4-6 weeks before first killing frost to allow adequate root development for winter survival.
Terminate at full bloom (typically mid-spring) for maximum nitrogen contribution; mow, roll, or incorporate before seed set to prevent volunteer issues.
Mix with a winter cereal (rye or oats) for mutual support — the cereal provides structure for the vine to climb and reduces lodging.
