Komatsuna Tendergreen Mustard Spinach Seeds – 500 Japanese Mustard Greens

Komatsuna Tendergreen, also known as Japanese mustard spinach, is a fast-growing leafy green prized for its mild, sweet flavor and crisp texture. This versatile Asian vegetable produces tender, spoon-shaped leaves that are delicious raw in salads or lightly cooked in stir-fries, soups, and pickles. Unlike many mustard greens, Komatsuna offers a pleasant, non-pungent taste that appeals to a wide range of palates. Its quick maturity makes it an excellent choice for succession planting, and it performs well in both spring and fall gardens, tolerating light frost for extended harvests.

Planting & Care

Sow Komatsuna seeds directly in the garden as soon as the soil can be worked in spring, or in late summer for a fall crop. Plant seeds 1/4 to 1/2 inch deep, spacing them 1 inch apart; thin seedlings to 4-6 inches when they are 2-3 inches tall. For a continuous supply, sow small batches every 2-3 weeks. Keep the soil consistently moist but not waterlogged, and provide shade during hot weather to prevent bolting. Mulching helps retain moisture and suppress weeds.

Fertilize lightly with a balanced organic fertilizer if growth appears slow. Harvest outer leaves when they reach 6-8 inches long, or cut the entire plant at the base for a cut-and-come-again harvest. Komatsuna is relatively pest-resistant, but watch for flea beetles and aphids; row covers can help protect young seedlings. With minimal care, you can enjoy multiple harvests from a single planting.
