A cool season crop, spring radishes grow best in 50⁰F to 65⁰F weather. Once sown, you’ll see leafy green shoots above the soil in just three or four days.

A “cut-and-come-again” plant, kale’s young and tender leaves can be culled continually throughout the growing-season once the plant is about 2-inches tall.
