Seeds, Mustard Komatsuna Red F1 (West Coast Seeds)

Komatsuna Red mustard seeds tolerate heat well and can be planted from spring to fall. The seeds do not need warm soil to germinate, so they can be planted in late winter for spring harvests as well. Try some in containers on the balcony. The leaves are round, flat and purple on top with green undersides and green stems. They are good in salads, sandwiches, and stir-fries.

Plants are fast-growing, productive, tasty, and very easy to grow.

Matures in 21 days (baby), 40 days (full size). (Hybrid seeds)

Exposure Full-sun to partial shade

Timing
Mustards are cool season plants that grow quickly and then bolt. Direct sow with frost protection as early as late winter or without protection from early to late spring. Sowing short rows every 3 weeks allows for a continuous harvest of both baby leaves and full sized plants. Sow again in late summer for late fall and winter harvests. Optimal soil temperature: 21°C (70°F). Seeds should sprout in 5-10 days.

Starting
If growing to full size, sow 3-4 seeds in each spot you want a plant to grow. Sow 5mm-1cm (¼-½”) deep and thin to the strongest plant, spaced 10-15cm (4-6″) in the row. All mustards can be grown in containers for baby salad greens. Sow these as you would mesclun mixes, with seeds spaced as near as possible to 1cm (½”) apart.
