Radish Pink Seeds pack of 70-100 seeds

Radishes prefer fertile, well-drained, deep, sandy soils rich in organic matter for best growth. Most light soils in Utah are well-suited for radish production. Heavy soils need to be amended with plenty of compost to allow good root development.

Before planting, determine fertilizer needs with a soil test and use the recommendations given in the test report. If fertilizer applications are warranted, work the fertilizer into the top 6 inches of soil. If you fertilize with compost, apply only 1 inch of well-composted organic matter per 100 square feet of garden area.

Radishes are always grown from seed. Radishes can be sown after soils reach 40ºF. Seeds germinate best at 55-75ºF and require 5-10 days to emerge. Seeds should be planted ½ inch deep. Maintain a uniform and moist soil surface to ensure good plant stands.

Radishes grow best when temperatures do not exceed 80ºF. Plant radishes at 10-day intervals to maintain a steady supply throughout the year. Fall plantings should start in mid-to-late August to avoid the summer heat. Thin closely spaced plants to encourage good root size. Radishes should be thinned to 1-2 inches between plants in the row with rows 10-12 inches apart. High summer temperatures trigger flower stalk development in many varieties. Hot weather also causes bitterness, increases “hot” flavors, and causes root hollowness. Cooler conditions improve root flavor and quality.

Water radishes regularly. Water requirements depend on soil type. Mulching around the plants helps to conserve soil moisture. Use drip irrigation if possible. Moisture fluctuations cause root cracking, slow leaf development, and contribute to “hot,” bitter roots. Stress during the first 6 weeks of growth often leads to premature flowering and low yields.

Apply ¼ cup per 10 feet of row of a nitrogen-based fertilizer (21-0-0) 3-4 weeks after emergence to encourage rapid plant growth. Place the fertilizer to the side of the plants and irrigate it into the soil.
