History & Origins: The Charleston Grey Watermelon is a classic heirloom variety known for its oblong shape, tough rind, and sweet, juicy flesh. The Charleston Grey Watermelon is prized for its hardiness, ability to resist fusarium wilt and anthracnose, and its refreshing, classic watermelon flavor!
Watermelons were first cultivated in Africa before spreading north into Mediterranean countries and, later, to other parts of Europe. The transatlantic slave trade was the main vehicle by which the watermelon made its way to the Americas. Before it became a racist stereotype in the Jim Crow era, watermelon once symbolized black self-sufficiency. After the Civil War, newly freed African Americans grew, ate and sold watermelon—the fruit became a symbol of freedom
Key Characteristics: Oblong and elongated shape, typically reaching 24 inches in length. Light gray-green with a smooth, uniform texture. The thick rind makes it resistant to cracking and excellent for storage and shipping. Bright red, sweet, and crisp, with a high sugar content. Typically black, scattered throughout the flesh. Fruits can weigh between 20–40 pounds, making it a large variety.
Growing Requirements: Plant after the last frost, when the soil is warm (ideally 70°F or higher). Matures about 85–100 days from planting to harvest. Requires full sun for optimal growth and sweetness. Prefers well-drained, sandy loam soil with a pH of 6.0–6.8. Needs consistent watering, especially during flowering and fruit development. Avoid overwatering as it can lead to poor fruit quality. Use mulch to retain soil moisture and prevent weeds. Plant seeds or transplants about 3–4 feet apart in rows spaced 6 feet apart. Vigorous vining plants that can spread significantly, requiring ample garden space.
Allow room for the vines to spread, as this variety can be quite vigorous. Flowers rely on bees for pollination; plant companion flowers to attract them. Check for ripeness by looking at the underside of the fruit (it should turn creamy yellow) and the drying of the tendril nearest to the fruit.
NUTRITIONAL VALUE: Watermelon is predominantly composed of water, aiding in maintaining proper hydration levels in the body. Beyond its thirst-quenching properties, it is a rich source of vitamins, particularly vitamin C, which supports the immune system and promotes skin health. It also contains vitamins A and B6, contributing to vision and metabolic processes. Watermelon's vibrant red hue signifies the presence of the antioxidant lycopene, linked to potential health benefits, including heart health and reducing oxidative stress. The fruit is naturally low in calories, making it a guilt-free option for those watching their calorie intake. Additionally, watermelon provides essential minerals such as potassium, crucial for maintaining electrolyte balance and supporting proper heart function.
FOOD PREP: The most popular way to eat watermelon is to slice the watermelon into wedges or cubes, providing a convenient and mess-free way to enjoy this hydrating fruit. For a twist, consider making watermelon skewers by threading the cubes onto sticks and alternating with other fruits like mint or feta cheese for a delightful appetizer. Turning watermelon into a chilled soup or gazpacho offers a unique and cooling option on warm days. Additionally, blending watermelon into smoothies or juices provides a refreshing beverage bursting with flavor. Experiment with savory combinations by adding watermelon to salads with feta, mint, and balsamic glaze for a sweet and savory contrast. Frozen watermelon cubes make for a healthy and tasty snack while incorporating the fruit into sorbets, popsicles, or granitas adds a playful touch to desserts. The seeds of a watermelon are also considered a culinary delight, with a slightly nutty flavor.
GROWING TIPS: Annual. Plant watermelon into 12-inch-tall hills of soil that are spaced at least 6 feet apart. Sow 6–8 seeds per hill, later thinning to 3–4 plants per hill. Sow watermelon seeds ½-inch deep. Water seeds into the hills after planting.
