Shop the highest quality Southern Giant Curled Mustard seeds for a robust and spicy garden harvest. If you are looking for the ultimate mustard green for flavor and texture, this 1935 All-America Selections winner is the "real deal." Southern Giant Curled is beloved for its massive, bright green leaves that feature heavily curled and fringed edges. At The Seed Guy, we recommend this variety for its bold, "uptown" peppery kick that adds incredible depth to stews, salads, and traditional boils. It is as decorative in the garden as it is delicious on the plate.
In the garden, Southern Giant Curled is a fast-growing powerhouse that thrives in cooler temperatures. It is a fantastic companion plant for onions and southern peas, and its thick, ruffled leaves are remarkably cold-hardy, often surviving a light frost which only serves to sweeten the flavor. Because of its upright growth habit, it stays cleaner than flatter varieties, making harvest and washing a breeze. At The Seed Guy, our seeds are tested for elite germination and leaf curl uniformity, ensuring you grow a crop that looks like it belongs on a magazine cover.

Southern Giant Curled Mustard Planting Instructions:
1. When to Plant: Best grown in the cool seasons of spring and fall. Sow 4-6 weeks before the last spring frost or 6-8 weeks before the first fall frost.
2. Preparation: Requires fertile, well-drained soil. Work in compost to ensure plenty of nitrogen for leafy growth.
3. Sowing: Sow seeds 1/4 inch deep. For a continuous harvest of young, tender leaves, sow a new row every 2 weeks.
4. Care: Keep soil consistently moist. If the soil dries out, the leaves can become excessively spicy. Thin plants to 6-12 inches to allow for full leaf expansion.
5. Pests and Diseases: Aphids and Flea Beetles can be attracted to the tender leaves. Use a strong spray of water or organic insecticidal soap if needed. To prevent leaf spot and downy mildew, water at the soil level and avoid getting the frilly leaves wet late in the day.
