How to Grow Saisai Leaf Radishes
Choose a location with good soil and full sun. Amend the soil as needed. Sow 25 seeds per foot in rows 12 to 18 inches apart; seeds should be planted 1/4" deep. Thin seedlings gradually to 1 plant every 3 to 4 inches. Water plants consistently and fertilize as needed. Plant rows in succession to spread out your harvest.
Harvesting Leaf Radishes
Harvest your leaf radishes once their leaves reach the desired size. They can be eaten as microgreens or fully grown at 12 inches tall. Cut plants at the base or pull up the entire plant. Store in the vegetable crisper in your fridge to keep them fresh and crisp.
Don’t throw away the seedlings you thin out! They are mild and tender at that size and make a great nutritious snack.
Culinary Tips
Leaf radishes have a variety of uses, both raw and cooked. If you can make it with mustard greens, you can make it with radish leaves! Serve in salads, make a healthy dip, or steam and serve with butter. Substitute for spinach in soups and stir-fries. Looking for something new? Try pickling them the Japanese way and make tsukemono!
