Jewel lettuce offers gardeners a visually appealing and flavorful addition to their beds. This variety stands out for its distinctive appearance, making it a popular choice for those seeking both beauty and utility. Its compact size also makes it suitable for various growing spaces.
Understanding Jewel Lettuce
Jewel lettuce, often referred to as Little Gem, is a miniature romaine variety known for its compact, upright growth habit. Its leaves are typically bright green, sometimes with a reddish tint, forming an oblong head with a crisp, compact heart. This lettuce combines the succulence and sweetness of butterhead lettuce with the refreshing crunch of romaine. The name “Jewel” or “Little Gem” aptly describes its petite size. Unlike larger romaine varieties, jewel lettuce maintains a tender texture while still offering a satisfying crispness.
Cultivating Jewel Lettuce
Site Selection and Soil
Jewel lettuce thrives in conditions ranging from full sun to partial shade, with some shade beneficial during warmer months to prevent bolting. The soil should be well-draining and rich in organic matter. A soil pH between 6.0 and 7.0 is suitable for lettuce production. Adding compost before planting enhances fertility and structure, encouraging robust plant development.
Planting Seeds
Jewel lettuce seeds can be direct-sown outdoors or started indoors for transplanting. For direct sowing, plant seeds 2 to 4 weeks before the average last frost date, when soil temperatures are at least 40°F, ideally between 60°–70°F. Sow seeds shallowly, covering them with approximately 1/4 inch of finely sifted soil. Aim for plants to be about 6 inches apart if growing to full size, or closer for “cut-and-come-again” harvesting of smaller leaves. Succession planting every few weeks ensures a continuous supply throughout the growing season.
Watering and Fertilizing
Consistent moisture is important for jewel lettuce; the soil should remain evenly moist but not waterlogged, which can lead to root issues. Daily hand watering may be necessary in warmer climates, especially for plants in containers. Lettuce has a shallow root system. While nitrogen is the primary nutrient needed, balanced fertilization with moderate amounts of potassium and phosphorus supports healthy growth. Organic options such as fish emulsion or manure tea can be applied weekly for nutrient delivery.
Managing Pests and Diseases
Jewel lettuce typically has few pest or disease issues when given proper conditions, though common garden pests like aphids, slugs, and cutworms can sometimes affect it. Good air circulation helps deter pests like aphids and whiteflies. Diseases such as downy mildew or bottom rot can occur in overly wet or humid conditions. Ensuring well-draining soil and avoiding overhead watering minimizes disease risk. Regular inspection allows for early detection and management of any potential problems.
Harvesting and Using Jewel Lettuce
Jewel lettuce can be harvested when heads reach 5 to 7 inches tall, typically 50 to 70 days after planting. Two primary methods exist: “cut-and-come-again” or harvesting the entire head. For the “cut-and-come-again” approach, remove individual outer leaves as needed, allowing the plant to continue producing and leaving at least half the plant intact for regrowth. Alternatively, cut the entire head at ground level. Harvesting in the morning yields the freshest, most crisp leaves.
This lettuce has a crisp texture, sweet flavor, and tender leaves. Its compact size makes it ideal for single-serving salads, and it pairs well with various dressings, including vinaigrettes. It can be sliced lengthwise to showcase its pale, blanched heart, creating an appealing presentation. Beyond salads, its sturdy yet tender leaves are suitable for sandwiches, wraps, or as a garnish.
