Best varieties of watermelon to grow in Alabama

In Alabama, there are several varieties of watermelon that tend to grow well due to the warm climate and long growing season. Here are a few recommended varieties:

  1. Crimson Sweet: This is a popular variety known for its sweet, juicy flesh and high sugar content. It has a dark green rind with light green stripes. Crimson Sweet is a reliable choice for Alabama’s climate.
  2. Charleston Gray: This variety is known for its large, oblong shape and thick, tough rind, making it ideal for transportation. It has sweet, crisp flesh and is resistant to many common watermelon diseases.
  3. Sugar Baby: If you have limited space or want to grow watermelons in containers, Sugar Baby is a great choice. It is a small, round watermelon with a dark green rind and sweet, red flesh. It matures relatively quickly, making it suitable for shorter growing seasons.
  4. Jubilee: Jubilee watermelons are known for their large size and sweet, flavorful flesh. They have a light green rind with dark green stripes. This variety is well-suited for Alabama’s hot summers.
  5. Black Diamond: Black Diamond watermelons are known for their large size and dark green rind. They have sweet, juicy flesh and are a popular choice for home gardeners in Alabama.

Remember to consider factors such as disease resistance, days to maturity, and personal preferences when selecting watermelon varieties for your garden in Alabama.

When to plant watermelon in Alabama

The best time to plant watermelon in Alabama is typically in late spring or early summer, once the soil has warmed up and the danger of frost has passed. This is usually around mid-April to mid-May. Watermelons require warm soil and temperatures between 70-90°F (21-32°C) for optimal growth. Planting too early, when the soil is still cool, can lead to poor germination and stunted growth. It’s important to check the local weather and soil conditions before planting to ensure the best chance of success.

How to grow watermelon

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 a long growing season. They require full sun and well-drained soil with a pH level between 6.0 and 6.8. Prepare the soil by adding organic matter like compost or aged manure to improve its fertility and drainage.
  2. Variety Selection: Choose a watermelon variety that suits your climate and preferences. Consider factors like size, flavor, and disease resistance. Common varieties include Crimson Sweet, Sugar Baby, and Jubilee.
  3. Seed Starting: Watermelon seeds can be started indoors 2-3 weeks before the last frost date or directly sown in the garden when the soil temperature reaches at least 70°F (21°C). Sow 2-3 seeds per hole, 1 inch deep, and thin to the strongest seedling once they germinate.
  4. Spacing: Watermelon plants require ample space to spread and grow. Plant them in rows with 6-8 feet spacing between each plant and 8-12 feet between rows. This ensures good air circulation and prevents overcrowding.
  5. Watering: Watermelon plants need consistent moisture throughout their growing season. Provide deep, regular watering to keep the soil evenly moist, especially during dry spells. Avoid overwatering, as it can lead to root rot.
  6. Fertilization: Watermelons are heavy feeders. Apply a balanced fertilizer or compost before planting and side-dress with nitrogen-rich fertilizer once the vines start to develop. Follow the package instructions for the appropriate dosage.
  7. Mulching: Mulching helps conserve soil moisture, suppress weeds, and regulate soil temperature. Apply a layer of organic mulch, such as straw or wood chips, around the plants, leaving space around the stems to prevent rot.
  8. Trellising: While watermelons can be left to sprawl on the ground, trellising can save space and provide better airflow, reducing the risk of diseases. Use trellises or stakes to support the vines and tie them gently as they grow.
  9. Pollination: Watermelon plants require pollination to set fruit. Bees and other pollinators are attracted to watermelon flowers, so avoid using pesticides that may harm them. If pollinators are scarce, you can hand-pollinate by transferring pollen from male flowers to female flowers using a small brush or cotton swab.
  10. Pest and Disease Management: Common pests that affect watermelons include aphids, cucumber beetles, and squash bugs. Monitor your plants regularly and take appropriate measures like using insecticidal soap or introducing beneficial insects to control pests. Diseases like powdery mildew, fusarium wilt, and anthracnose can also affect watermelons. Choose disease-resistant varieties and practice crop rotation to minimize the risk.
  11. Harvesting: Watermelons are ready for harvest when the fruit has reached full size, the underside turns creamy yellow, and the tendril closest to the fruit has dried up. Gently tap the fruit; if it sounds hollow, it’s likely ripe. Cut the watermelon from the vine using a sharp knife, leaving a short stem attached.

By following these steps and considering the specific needs of watermelon plants, you can successfully grow delicious and juicy watermelons in your garden.

When to harvest watermelon in Alabama

In Alabama, watermelons are typically harvested from late June to early August. The exact timing can vary depending on the specific variety of watermelon being grown and the weather conditions during the growing season. It is important to monitor the watermelon plants closely for signs of ripeness before harvesting. Some indicators of ripeness include a dull or matte appearance of the fruit’s skin, a yellow or cream-colored spot on the underside where the watermelon was resting on the ground, and a hollow sound when tapped. Additionally, the tendril closest to the fruit should be dry and brown. Harvesting watermelons at the right time ensures optimal sweetness and juiciness.

Common watermelon plant problems and fixes

Common problems when growing watermelon and their fixes include:

  1. Poor pollination: Watermelon plants require proper pollination for fruit set. If there is a lack of bees or other pollinators in your garden, you can manually pollinate the flowers using a small brush or cotton swab. Gently transfer pollen from the male flowers to the female flowers.
  2. Blossom end rot: This is a condition where the bottom end of the fruit becomes black and rots. It is caused by a calcium deficiency or inconsistent watering. To prevent blossom end rot, ensure consistent watering, provide adequate calcium through soil amendments or foliar sprays, and maintain proper soil pH.
  3. Powdery mildew: Powdery mildew is a fungal disease that appears as a white powdery coating on the leaves. To prevent powdery mildew, ensure good air circulation around the plants by spacing them properly and avoid overhead watering. If powdery mildew appears, treat it with organic fungicides or neem oil.
  4. Pest infestations: Common pests that attack watermelon plants include aphids, cucumber beetles, and squash bugs. Use organic pest control methods such as insecticidal soaps, neem oil, or introducing beneficial insects like ladybugs or lacewings to control these pests.
  5. Over or under-watering: Watermelon plants require consistent moisture, especially during fruit development. Overwatering can lead to root rot, while under-watering can cause the fruits to crack or become small. Water deeply and regularly, ensuring the soil is moist but not waterlogged. Mulching around the plants can help retain moisture and regulate soil temperature.
  6. Lack of sunlight: Watermelon plants need full sun for optimal growth and fruit development. Ensure they receive at least 6-8 hours of direct sunlight daily. If your garden has shaded areas, consider growing smaller varieties or using reflective materials to increase sunlight exposure.
  7. Improper fertilization: Watermelon plants require balanced nutrition for healthy growth. Use a balanced fertilizer or organic compost before planting and apply additional fertilizer during the growing season as per the specific requirements of your soil. Avoid excessive nitrogen, as it can result in lush foliage but fewer fruits.

Remember to regularly monitor your watermelon plants for any signs of disease or pest infestation and take appropriate action promptly.
