Answer: Radishes prefer to grow in the cool weather of spring, autumn and winter. They also grow best with consistent moisture. If radishes are grown in too much heat with sporadic watering, they will fail to develop well and will become spicy and tough. I'd suggest planting them during the cooler early winter months for a bumper spring crop. Given the right climactic conditions: cool temperatures and moist soil, radishes will be a tender crop.
