A type of edible vegetable, it mainly grows as an annual plant - which means it typically only grows best for a single growing season. Normally grows with a mound-forming habit. This plant tends to bloom in early summer, followed by first harvests in late spring.

These plants will not grow well with Japanese mustard spinach so avoid planting these within close proximity:
Annual legumes, such as peas, pole or bush bean, chickpea, cowpea, snow pea, lentils, lupines, fragrant sweet pea, runner bean, hyacinth bean, and yard weeds in the legume family such as clovers, vetches and alfalfa, should not be allowed to grow near this plant. All of these can act as host plants for Alternaria fungus and then transmit it to the Komatsuna.
These problems, diseases and pests are known to affect Japanese mustard spinach plants:
Alternaria mildew may become a problem. It helps to practice crop rotation, plant certified or treated seeds, use an antifungal spray such as baking soda, and keep garden clear of host weeds such as wild legumes – yellow clover, etc.
Cabbage moth aka cabbage butterfly is a significant pest of this plant. Covering the plant in fine netting works great, and using strongly scented companion plants such as cinnamon basil or rosemary in very close proximity to the komatsuna works to some extent… Not as well as netting, though.
