How to Grow Miike Giant Mustard

Plant the seeds directly in the garden starting at about 4-6 weeks before the last frost for spring planting, or late summer to early fall for a fall harvest. This plant matures pretty quickly, but will bolt in high temperatures. Plant additional rows every 2 weeks for a continuous harvest. Plant the seeds 0.5 inches deep, starting at 4 inches apart. Leave them at this distance for the baby greens, and thin them to 8 inches apart for full-sized greens. Keep the soil moist by watering regularly. They will bolt in higher temperatures. Harvest the full plant before this happens, as warm temperatures make the greens bitter. Starting the seeds in early fall allows more time for growth.

Harvesting Miike Giant Mustard

For baby greens, trim the outer leaves when they are 3-6 inches tall. Keep trimming the outer leaves. If you are growing some plants to full size, you can harvest every other plant when they are right at 6 inches tall, keeping the remaining plants 8 inches apart. This will give you nice baby greens and allow the remaining Miike Giant Mustard plants to reach full maturity with space to grow.

For fully mature plants, trim individual outer leaves off at the bottom once they are full-sized, 12 to 18 inches in length. This will allow the plant to keep growing. When the entire plant is fully grown and mature, cut the plant at the base.

Culinary Tips

These delicious broad-leafed greens are great for sandwiches or as a salad green. They can be stir-fried, used in soups, or pickled. Try traditional Indian mustard greens by boiling, puré-ing, and stir-frying with garlic and hot peppers. Then serve on Indian naan or your preferred style of bread.

Tips From Our Gardeners

"Growing different varieties of mustard is one of my favorite fall projects. I have found that mustard is a cool-weather crop, grown most easily in the fall. Sunlight is an important thing to prioritize. Mustard does fine in some partial shade, but it does need at least 6-8 hours of sunlight a day. For growing in the springtime into the summer, it’s ok to shade the plants at midday to keep them a bit cooler. In the fall, I make sure that they are positioned to get as much sunlight as possible!"
