Growing Information:

Light: Watermelons, including the Charleston Gray, thrive in full sun. They require at least 8 hours of direct sunlight each day to produce large, sweet fruit.

Soil: These watermelons prefer well-draining, sandy-loam soil that is rich in organic matter. The soil should be slightly acidic to neutral, with a pH range of 6.0 to 7.0. Incorporating compost or organic matter into the soil will help improve its fertility.

Planting Tips:

• Start seeds indoors 3–4 weeks before the last frost date or sow them directly outdoors once the soil has warmed to around 70°F (21°C).
• If starting indoors, plant the seeds about 1 inch deep in seed trays or small pots. Transplant seedlings outdoors after the danger of frost has passed and the soil is warm.
• Space plants about 36–42 inches apart to give each vine plenty of room to spread.
• Watermelon plants have long vines, so consider planting them in a spacious area or using a trellis for vertical growth if space is limited.

Watering: Watermelon plants require consistent moisture, especially during fruit development. Keep the soil evenly moist but not waterlogged. Water deeply once a week or more during dry spells, but be cautious not to overwater, as this can lead to root rot.

Benefits:

• Delicious Fruit: The Charleston Gray Watermelon is known for its sweet, juicy, and crisp flesh, making it a perfect fruit for hot summer days.
• Disease Resistance: This variety is relatively resistant to common watermelon diseases, such as fusarium wilt, powdery mildew, and anthracnose, ensuring a healthy crop.
• High Yield: A single plant typically produces several large melons, making it a productive variety for home gardeners looking for a reliable harvest.
• Versatile Use: The watermelon’s bright red flesh is perfect for fresh eating, fruit salads, smoothies, or even as a garnish for savory dishes.
• Long Shelf Life: Thanks to its thick rind, the Charleston Gray Watermelon has a relatively long shelf life, allowing it to be stored for a longer period than other watermelon varieties.

Growing Zones: Charleston Gray Watermelon grows best in USDA Hardiness Zones 3–10. It thrives in warm climates with hot summers and is well-suited to areas that experience long, sunny growing seasons. It can be grown in colder climates by starting seeds indoors and transplanting after the last frost.

How to Use in the Garden:

• Ornamental and Edible: Watermelons like the Charleston Gray are not only a tasty treat but also provide a lovely visual element to the garden with their sprawling vines and large fruit.
• Raised Beds or Traditional Rows: Plant the seeds in raised beds, rows, or mounds, depending on your garden’s layout. Watermelons need plenty of space for their vines to spread.
• Companion Planting: Watermelons can be grown alongside other crops that tolerate heat, such as corn, beans, or sunflowers. These plants can provide natural shade for the watermelon vines during hot summer months.
• Vertical Gardening: If you are limited on space, consider using a vertical gardening system, such as a trellis, to grow your watermelon vines upward, saving space while still producing large fruit.
