Tendergreen Mustard Planting Instructions:
1. When to Plant: Tendergreen is incredibly flexible. Direct sow as soon as the soil can be worked in early spring. Unlike most greens, it can be planted every 2 weeks throughout the summer for a continuous "Succession Harvest" and again in late summer for a fall crop.
2. Preparation: Choose a location with full sun to partial shade. Mustard greens love nitrogen-rich soil, so amend your bed with plenty of compost or organic matter before sowing.
3. Sowing: Sow seeds 1/4 inch deep. For baby greens, sow seeds thickly in rows. For large, mature leaves, space plants or thin seedlings to 6-12 inches apart. Rows should be 12-18 inches apart to allow for easy weeding.
4. Watering and Care: Keep soil consistently moist to prevent the leaves from becoming too spicy or tough. Mulching around the plants will help regulate soil temperature and keep the "Quick-Crop" growing rapidly.
5. Harvesting: You can begin harvesting individual outer leaves when they reach 3-4 inches long (baby stage) for the mildest flavor. For a full harvest, cut the entire plant at the base. Frequent harvesting of outer leaves encourages the plant to continue producing fresh, tender growth from the center.
