How To Grow
GROWER TIP: You can try soaking radish seeds in water for a few hours before planting to encourage faster germination, though it’s not strictly necessary. For optimal growth, start them in cool weather—ideally in early spring or fall—either outdoors in well-drained soil with full sun or indoors under grow lights, keeping the soil consistently moist and temperatures between 50-65°F, as radishes thrive as a cool-weather crop. To maintain healthy plants, thin seedlings to prevent overcrowding, water regularly to avoid woody roots, and harvest when the roots feel firm and vibrant for the best flavor.
