Radishes are a hardy, quick-growing crop that can be ready in as early as 3 weeks.
They prefer cool, moist, loose and fertile soil, but essentially these are root crops and need loose soil to grow.
They do not like drought conditions--need constant moist soil conditions.
They are moderate feeders, so they need some fertilization.
