Ease of Cultivation and vibrant edible flowers: The Jewel Mix nasturtium is a colorful and versatile flowering plant known for its bright, jewel-toned blossoms and peppery leaves. This variety is easy to grow, making it ideal for both novice and experienced gardeners. Nasturtiums are not only beautiful but also edible, adding a spicy flavor to salads and garnishes, while their flowers attract beneficial pollinators to the garden.

Direct Sowing: For direct sowing, plant the seeds outdoors after the last frost date when the soil temperature reaches at least 50°F. Sow the seeds 1/2 inch deep and 10-12 inches apart in rows that are 18-24 inches apart. Germination usually occurs within 7-14 days. Keep the soil consistently moist but not overly saturated. Nasturtiums prefer poorer soils, so avoid excessive fertilization. Harvest the flowers and leaves throughout the growing season for use in salads and culinary dishes.

Early Sowing for Seedlings: For an early start, sow seeds indoors 4-6 weeks before the last expected frost. Use seedling trays filled with quality potting mix, placing one seed per cell. Maintain a temperature of 65-75°F to encourage germination. Once the seedlings have developed their first true leaves and the danger of frost has passed, transplant them into the garden, spacing the plants 10-12 inches apart. Water thoroughly after transplanting and mulch around the base to retain moisture and suppress weeds.

Harvesting: To determine when Jewel Mix nasturtiums are ready to harvest, look for flowers that are fully opened and vibrant in color. The leaves can be harvested once they are large enough, typically when they are 2-4 inches in diameter. Regularly harvesting the flowers encourages continuous blooming. For the best flavor and quality, pick the leaves and flowers in the morning when they are still cool and fresh.
