Planting & Care
  • Mustard greens are a cool season vegetable. Seeds germinate best in temperatures between 45 F and 85 F.
  • Begin sowing directly outdoors 3 weeks before the last frost date. Plant seeds 1/3 to 1/2 inch deep, spacing seeds 1 inch apart.
  • Thin seedlings to 6 inches for smaller varieties and 18 inches for larger varieties
  • Seedlings that are thinned out can be added to salads or sandwiches
  • For a continual harvest make repeated plantings every 2 to 3 weeks
  • Mustard is fast growing and can be quick to bolt in warmer temperatures. Higher temperatures and drier soil results in a more intense pepper flavor and tougher leaves
  • The cooler temperatures of fall provide more favorable growing conditions that result in a better quality harvest
  • Mulch soil around plants to maintain soil moisture and suppress weeds
  • Use floating row covers earlier in the growing season to protect plants from insect pests
Problems
Cabbage worms, aphids
Varieties
  • Florida Broadleaf - slow to bolt, large leaves
  • Green Wave - All-America Selections Winner, 24", slow to bolt
  • Red Giant - 18", ornamental purple tinged leaves that intensify in color in cooler temperatures
