Radish Seeds,
Red Beauty

Red Beauty radishes are best grown in cool weather, late summer to early fall. They can be sown up until 4 weeks before the first expected frost in fall. The optimal temperature range for growing these radishes is between 50-75 F, to maintain their mild flavor and crisp texture​.

To plant Red Beauty radishes, sow seeds directly in the garden about 1/4 inch deep and 1 inch apart. Space rows 12 inches apart to give the plants ample room to grow. Once seedlings emerge, thin them to about 4 inches apart to avoid overcrowding, which can hinder root development. Succession plant for a continuous harvest.

Make sure that the plants receive about 1 inch of water per week to maintain soil moisture and prevent the roots from becoming tough. Drip irrigation or a soaker hose can provide consistent moisture. Keep the planting area free of weeds to reduce competition for nutrients. Usually, no additional fertilization is needed if the soil is rich in organic matter. Adding compost to the soil before planting can enhance fertility​.

• Radishes are insect-pollinated, so you'll need to isolate varieties by up to 1⁄2 mile or stagger plantings to avoid flowering at the same time.
• Staggering can be easy because of the radish's quick maturity.
• Allow flower stalks to shoot up and seed pods to dry on the plant before picking pods and opening by hand to remove the seeds.
• Seeds will remain viable for up to 5 years when stored in an airtight container.
