Kale likes well-drained, fertile soil high in organic matter, with a pH of 6.0 to 7.5. High rainfall areas will need an application of lime. Slightly alkaline soil is tolerated. This plant prefers plentiful, consistent moisture. Drought is tolerable, but quality and flavor of leaves can suffer. Spread Gaia 4-4-4 Complete Organic Fertilizer over the bed before planting.
