How to Grow Starburst Chinese Radishes To grow Starburst radishes, prepare your planting bed by loosening up the soil at least 6 inches deep and adding organic matter if needed. Sow one seed every 1/2 inch and thin seedlings to 3 inches apart after germination. Care for your seedlings by giving them consistent water and nutrients as needed. This variety should be planted early in the spring or fall to ensure the best flavor.
Harvesting Chinese Radishes Starburst Chinese radishes take longer to mature than some other varieties at 60 days, but it is worth the wait. Once they are mature, harvest by pulling the plants at their bases or try digging up with a shovel or gardening fork.
Don’t be afraid to err on the side of caution and harvest your radishes early as waiting too long will result in a dramatic loss of flavor! If you aren’t ready to eat them yet, store them in a cool, dry place or in the fridge after removing the radish tops.
