Mizuna Seeds,
Early

Early mizuna is best sown in late winter or early spring for a spring harvest or in late summer for a fall harvest. It grows well in temperatures between 55-70 F, making it ideal for cooler climates. If starting indoors, sow seeds about 4 weeks before the last expected frost. In regions with mild winters, mizuna can also be grown throughout the winter months​.

To sow Early mizuna, plant seeds 1/4 inch deep directly into the garden or in containers. Space seeds about 1 inch apart in rows that are 12-18 inches apart. If starting indoors, sow seeds in trays and transplant seedlings when they are sturdy enough and after the danger of frost has passed. Thin seedlings to 6-12 inches apart once they reach about 2 inches in height to allow sufficient space for growth​.

Early mizuna requires consistent moisture and performs best in well-drained, fertile soil. Water the plants regularly, especially during dry periods, to keep the soil consistently moist. Apply a balanced fertilizer every few weeks to promote healthy growth. In hot weather, use mulch to retain soil moisture and prevent the plants from bolting. Keep the area around the plants free of weeds, which can compete for nutrients.

• To save seeds from Early mizuna, allow some plants to bolt and produce flowers.
• Once the flowers have matured and the seed pods are dry, harvest the pods and store the seeds in a cool, dry place.
• Mizuna seeds remain viable for up to four years when properly stored.
