The ‘Royal Sovereign’ strawberry is a heritage variety, over a century old. Bred in 1892 by Thomas Laxton in England, it gained recognition. This cultivar was widely popular between the 1920s and 1960s, even being served at Queen Elizabeth II’s coronation banquet. Its appeal stems from unique characteristics, captivating those who prioritize flavor and quality.
Distinguishing Characteristics
The ‘Royal Sovereign’ strawberry has an intensely sweet, aromatic flavor. Its flesh is softer, bright orange-pink to scarlet, and juicy. Though yields and shelf life may be lower, its taste compensates. Plants yield moderately, averaging 7 to 12 ounces per plant, primarily in mid-summer.
Cultivating Royal Sovereign Strawberries
Cultivating ‘Royal Sovereign’ strawberries requires attention to environmental needs and maintenance. These plants thrive with specific conditions. A structured approach leads to a rewarding harvest.
Site Selection and Soil Preparation
Royal Sovereign strawberries need full sun (at least eight hours daily) for fruit production. Well-draining soil is important; strawberries are sensitive to wet conditions that can cause root issues. Ideal soil pH for strawberries ranges from 5.5 to 6.5, though some tolerate up to 7.0. Amending soil with organic matter (e.g., composted manure) before planting improves drainage and fertility.
Planting Techniques
Plant ‘Royal Sovereign’ strawberries in early spring or late summer/early fall. For bare-root plants, spread roots in the hole, ensuring the crown is level with the soil surface. Planting too deep can cause rot, while planting too shallow may lead to drying out. Space plants 12 to 18 inches apart in rows, with rows 3 to 4 feet apart for air circulation and runner management. After planting, water thoroughly to settle the soil.
Ongoing Care and Maintenance
Watering is important for strawberries, especially during growth and fruiting, requiring one to two inches per week (including rainfall). Water in the morning to allow foliage to dry, reducing fungal disease risk. Fertilize established plants with a balanced fertilizer (e.g., 10-10-10 NPK) in late summer after harvest. Manage runners to maintain plant vigor and fruit size; allow some to root for replacement, but remove excessive ones to prevent overcrowding.
Pest and Disease Management
‘Royal Sovereign’ strawberries are susceptible to pests like aphids, spider mites, and slugs. Organic solutions like insecticidal soap or neem oil manage these pests. Common diseases include powdery mildew, grey mold, and leaf spot. Proper plant spacing and air circulation prevent fungal issues. Removing affected plant parts prevents disease spread.
Winter Protection
In colder climates, winter protection ensures ‘Royal Sovereign’ strawberry plant survival and productivity. After several frosts, in late autumn before freezing temperatures, apply straw mulch. This insulation protects crowns and roots from cold and temperature fluctuations, preventing frost heaving. Remove the mulch in early spring as new growth begins.
Harvesting and Enjoying Your Crop
Harvesting is the culmination of cultivation, and timing is important for peak ‘Royal Sovereign’ flavor. Berries are ready when fully red and detach easily. Grasp the stem above the berry and snap it off, or use small snips, to avoid bruising. Harvesting typically occurs in mid-summer (mid-June to mid-July). For best flavor and texture, consume ‘Royal Sovereign’ strawberries immediately; for short-term storage, keep them unwashed in a single layer in a shallow container in the refrigerator for a few days.
The Enduring Appeal
Despite modern varieties, ‘Royal Sovereign’ remains a choice for home gardeners due to its flavor. Its rich, intensely sweet, aromatic profile sets it apart, offering a traditional taste. Its historical significance adds charm, connecting gardeners to a long tradition of fruit cultivation. While yield may be moderate compared to commercial varieties, fruit quality makes it rewarding for those willing to provide care. ‘Royal Sovereign’ strawberries are suited for fresh eating, where their flavor is appreciated.
