Country of origin: United States. The supplier identifies this product as American-grown.

Since mustard greens thrive in cool weather, they taste best when grown as early in the spring as possible or as a fall crop. For a spring crop, direct sow the seed in full sun and rich soil about four weeks before the last expected spring frost and lightly rake them into the soil. Keep the rows 10-12" apart. When seedlings emerge, thin them to 5-6" apart. For a continual harvest, plant more Red Giant Mustard every 10-14 days. For fall planting, plant the seeds in late summer or early fall about 10 weeks before the first hard frost. Warmer climates can grow them from fall through spring. Keep the plants moist and free of weeds. A thick layer of mulch will help conserve moisture.

Keep unused seeds dry and cool in a clearly labeled, closed container. Protect the packet from humidity and temperature swings, and retain the variety name and sowing notes for your next planting. Use the species-specific directions below when deciding whether to start indoors, sow directly, soak seeds, or provide a cold period. Germination and growth vary with seed handling and local growing conditions.
