  4. Black Diamond: This variety is known for its large, dark green fruits with sweet, juicy red flesh. Black Diamond typically matures in about 85-90 days and is a good choice for gardeners looking for a larger watermelon variety.
  5. Moon and Stars: This unique heirloom variety features dark green skin with yellow “moon” and smaller yellow “stars” scattered across the rind. Moon and Stars watermelons have sweet, red flesh and usually mature in around 90-95 days.

Remember to consider factors such as available space, desired fruit size, and personal taste preferences when choosing a watermelon variety. Additionally, providing proper care, including adequate watering, fertilization, and pest control, will help ensure successful watermelon growth in West Virginia.

When to plant watermelon in West Virginia

The best time to plant watermelon in West Virginia is typically in late spring to early summer, when the soil temperature has warmed up to around 70°F (21°C) and there is no longer a risk of frost. This is usually around mid-May to early June. Watermelons require warm soil and temperatures between 70-90°F (21-32°C) for optimal growth. Planting too early when the soil is still cold can result in poor germination and stunted growth.

How to grow

Growing watermelon requires careful planning and attention to detail. Here are the steps and considerations to keep in mind:

  1. Climate and Soil: Watermelons thrive in warm climates with temperatures between 70-90°F (21-32°C). Choose a sunny spot in your garden with well-drained soil. The soil should be rich in organic matter and have a pH level between 6.0-6.8.
  2. Seed Selection: Choose watermelon seeds that are suitable for your climate and growing conditions. There are various varieties available, including seedless and seeded types. Consider factors such as size, flavor, and disease resistance when selecting seeds.
  3. Starting Seeds: Start watermelon seeds indoors 3-4 weeks before the last frost date in your area. Plant the seeds 1 inch deep in seed-starting trays or pots filled with seed-starting mix. Keep the soil consistently moist and maintain a temperature of 75-85°F (24-29°C). Transplant the seedlings outdoors when all danger of frost has passed.
  4. Transplanting: Watermelon seedlings should be transplanted outdoors when they have 2-3 true leaves and the soil temperature is consistently above 60°F (15°C). Space the plants 3-4 feet apart in rows that are 6-8 feet apart. Ensure that each plant has enough space to spread and grow.
  5. Watering: Watermelons require regular and consistent watering throughout their growing season. Provide deep watering to ensure the roots receive adequate moisture. Avoid overwatering, as it can lead to root rot. Mulching around the plants can help retain moisture and suppress weed growth.
  6. Fertilization: Watermelons are heavy feeders and require regular fertilization. Before planting, incorporate well-rotted compost or aged manure into the soil. Once the plants start to develop, apply a balanced fertilizer every 2-3 weeks. Follow the instructions on the fertilizer package for application rates.
  7. Pollination: Watermelons require pollination to set fruit. Bees and other pollinators are essential for this process. Encourage pollinators by planting flowers nearby and avoiding the use of pesticides that may harm them. If pollination seems inadequate, you can hand-pollinate by transferring pollen from male flowers to female flowers using a small brush or cotton swab.
  8. Pest and Disease Control: Common pests that may affect watermelons include aphids, cucumber beetles, and squash bugs. Monitor your plants regularly and use organic pest control methods if necessary. Diseases such as powdery mildew and fusarium wilt can also affect watermelons. Choose disease-resistant varieties and practice crop rotation to minimize the risk.
  9. Harvesting: Watermelons are ready for harvest when the fruit’s skin turns dull and the underside changes from white to yellow. Give the fruit a gentle tap – a hollow sound indicates ripeness. Cut the fruit from the vine using a sharp knife or pruners, leaving a short stem attached.

By following these steps and considerations, you can successfully grow delicious watermelons in your garden. Happy gardening!

When to harvest

In West Virginia, watermelons are typically harvested in late summer or early fall, around August or September. The exact timing can vary depending on the specific variety of watermelon you are growing and the weather conditions in a given year. To determine if a watermelon is ready for harvest, there are a few indicators to look for:

  1. Check the underside: The spot where the watermelon rests on the ground should turn from white or light green to a creamy yellow color.
  2. Tapping: Gently tap the watermelon with your knuckles. If it produces a deep, hollow sound, it is likely ripe. If the sound is dull or flat, it may not be ready yet.
  3. Skin color and texture: The skin of a ripe watermelon should have a dull appearance rather than a shiny or glossy one. Additionally, the skin should be firm and resistant to pressure.
  4. Tendril drying: Look for the tendril closest to the watermelon stem. If it has turned brown and dried up, it is a good indication that the watermelon is ripe.

Remember that it’s essential to monitor your watermelon plants regularly and observe these signs to determine the optimal time for harvest.

Common watermelon plant problems and fixes

There are several common problems that can arise when growing watermelon, along with corresponding fixes:

  1. Poor pollination: Watermelon plants require proper pollination to produce fruit. If you notice a lack of fruit set or misshapen fruit, it may be due to poor pollination. To fix this, you can hand-pollinate the flowers using a small brush or by transferring pollen from the male flowers to the female flowers.
  2. Blossom end rot: This is a condition where the bottom end of the fruit turns black and rots. It is usually caused by calcium deficiency or inconsistent watering. To prevent blossom end rot, ensure consistent soil moisture by watering regularly and evenly. Additionally, you can add calcium-rich amendments to the soil before planting.
  3. Powdery mildew: Powdery mildew is a fungal disease that appears as a white powdery coating on the leaves. It can weaken the plant and reduce fruit production. To control powdery mildew, ensure good air circulation around the plants by spacing them adequately. You can also apply fungicides labeled for powdery mildew control.
  4. Pest infestation: Common pests that can affect watermelon plants include aphids, cucumber beetles, and squash bugs. Regularly inspect your plants for signs of pest damage, such as yellowing leaves or chewed foliage. Use organic insecticides or insecticidal soaps to control pest populations. Additionally, you can employ physical barriers like row covers to prevent pests from reaching the plants.
  5. Overwatering or underwatering: Watermelon plants require consistent moisture, but overwatering or underwatering can lead to problems. Overwatering can cause root rot and other fungal diseases, while underwatering can result in stunted growth and poor fruit development. To ensure proper watering, monitor the soil moisture regularly and water deeply when the top inch of soil feels dry.
  6. Sunburn: Watermelon fruits can get sunburned if exposed to intense sunlight for extended periods. This can result in yellow or white patches on the fruit’s skin. To prevent sunburn, provide shade to the fruits using straw mulch or by placing a cloth or cardboard cover over them during the hottest part of the day.

Remember, prevention is key when it comes to common problems in watermelon cultivation. Providing optimal growing conditions, including well-draining soil, full sun exposure, and regular fertilization, can help minimize the occurrence of these issues.
