Early Mizuna mustard (Brassica rapa) - 100 Seeds

Description:

This early maturing Japanese mustard, also known as kyona mizuna, has a very mild mustard flavor. This milder flavor makes it more suitable for salads for those that don't like the typical spiciness associated with raw mustards. It has long slender stems and dark green, serrated leaves. Both cold and heat tolerant and slow to bolt, it is a vigorous green that branches prolifically. Suitable for harvesting at any stage, microgreens to mature plants. Cut-and-grow-again methods apply to this vegetable. Mizuna has become very popular as a salad green and is also delicious cooked. Mustards are potent soil fumigants. Incorporating the residues of mustard crops into your soil can reduce fungal diseases in your succession crop.

Sold as seeds for planting. Select this packet by its variety, quantity, and growing requirements; it is not a live plant.

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

In early spring, plant just below the surface of the soil. This seed germinates best at temperatures from 40-55 degrees F (4-13 degrees C). Keep the soil lightly moist until germination occurs, which usually takes place within 7-10 days. This seed also germinates well in late fall for a late season crop. Water occasionally and keep weeds down. This plant grows well in many soil types, and tolerates cold temperatures very well. It also grows well in containers. The leaves can be harvested for fresh greens starting at 4 weeks. For the best taste, harvest leaves about 4" long; leave at least 1" growing since this will enable the plant to continue producing leaves. Choose leaves that are crisp and show no sign of discoloration. Store the leaves in the refrigerator for up to 5 days.

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.
