Mustard Greens
Dr. Leigh Whittinghill, Assistant Professor of Urban Agriculture
Planting
Plant from early March to late May or from late July to early September. Summer plantings will bolt and produce seeds, affecting flavor.
Plant seeds at a depth of 1/4 -1/2 inches
Plants should be spaced 3 inches apart.
Stagger plantings to ensure a continuous harvest.
Care and Harvest
Provide 1 inch of water a week, including rain.
Mustard greens are ready to harvest 35-60 days after planting, when leaves reach the desired size. Baby mustard greens can be ready for harvest 20-30 days after planting.
Baby mustard can be cut when the entire plant reaches 3-6 inches tall. Full size varieties will each 12-18 inches tall.
Mustard can be cut and allowed to regrow for up to 4 harvests. Plants can regenerate in 2 weeks or less and will get taller with each regrowth. Harvest close to the bottom of the leaf, leaving most of the stem.
If the mustard bolts and goes to seed, the seed can be collected and used in pickling or other recipes. Collect seed pods when they are brown, break them open and separate out the seeds.
