Radish Seeds,
Pusa Jamuni

The Pusa Jamuni radish is a cool-weather crop that can be sown in mid-summer or fall. Sow seeds at least 4 weeks before the first expected frost in fall. The ideal temperature range for growing this radish is between 50-75 F, which helps maintain its flavor and texture. Be careful when planting during the hot summer months, as high temperatures can cause bolting and poor root development​.

Direct sow Pusa Jamuni radish seeds into the garden 1/2 inch deep and about 1 inch apart in rows spaced 12 inches apart. After germination, thin the seedlings to 4 inches apart to prevent overcrowding, which can lead to smaller roots. You can succession plant every 2-3 weeks to extend the harvest period​.

Maintain even soil moisture by watering the plants regularly, particularly during dry spells. Radishes require about 1 inch of water per week for optimal root development. Use organic mulch around the plants to help conserve moisture and reduce weed growth. Fertilizing is generally not necessary if the soil is rich in organic matter, but a light application of compost before planting can enhance growth. Keep the radish bed free of weeds, as competition can affect root size and quality.

• 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.
