Best varieties of watermelon to grow in Mississippi

In Mississippi, there are several watermelon varieties that tend to perform well due to the region’s warm climate and long growing season. Here are a few varieties that are known to be successful in Mississippi:

  1. Crimson Sweet: This is a popular variety known for its large, sweet, and juicy fruit. It has a dark green rind with lighter green stripes. Crimson Sweet is a widely adaptable variety and can thrive in Mississippi’s conditions.
  2. Jubilee: Jubilee watermelons are known for their excellent flavor and high sugar content. They have a thick, tough rind and deep red, crisp flesh. Jubilee is a heat-tolerant variety that can handle the hot summers of Mississippi.
  3. Charleston Gray: This variety is known for its large, oblong fruit with a light green rind and sweet, juicy red flesh. Charleston Gray is a vigorous grower and can tolerate Mississippi’s hot and humid climate.
  4. Sugar Baby: If you have limited space or want to grow watermelons in containers, Sugar Baby is a great choice. It produces small to medium-sized fruit with a dark green rind and sweet, red flesh. Sugar Baby is an early maturing variety, which is beneficial in areas with shorter growing seasons.
  5. Black Diamond: This variety is known for its large, round fruit with a dark green rind and sweet, juicy red flesh. Black Diamond watermelons can grow to be quite large, often reaching weights of 30-50 pounds. They are heat-tolerant and can thrive in Mississippi’s climate.

When selecting watermelon varieties, it’s important to consider factors such as disease resistance, days to maturity, and personal preferences for taste and texture. Additionally, ensure that you provide the plants with proper care, including adequate watering, fertilization, and pest control, to maximize their growth and yield.

When to plant watermelon in Mississippi

The best time to plant watermelon in Mississippi is typically in late April or early May. Watermelons require warm soil temperatures to germinate and thrive, so it’s important to wait until the danger of frost has passed and the soil has warmed up to at least 70°F (21°C). This timing allows the watermelon plants to establish themselves and grow during the warm summer months, which is ideal for their growth and fruit production.

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 70-85°F (21-29°C). Choose a location that receives full sun for at least 6-8 hours a day. The soil should be well-draining, loose, and rich in organic matter. Conduct a soil test to ensure the pH level is between 6.0-7.5.
  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 like size, flavor, and disease resistance when selecting seeds.
  3. Starting Seeds: Watermelon seeds can be started indoors 2-4 weeks before the last frost date in your area. Plant the seeds in biodegradable pots or seed trays filled with seed-starting mix. Keep the soil moist and maintain a temperature of around 75°F (24°C) until the seedlings emerge.
  4. Transplanting: Once the danger of frost has passed and the soil temperature is consistently above 60°F (15°C), transplant the seedlings into the garden. Space the plants 3-4 feet apart in rows that are 6-8 feet apart. Ensure the soil is well-prepared with compost or aged manure.
  5. Watering: Watermelons require consistent moisture throughout their growing season. Provide 1-2 inches of water per week, either through rainfall or irrigation. Avoid overhead watering to prevent diseases. Use drip irrigation or soaker hoses to water at the base of the plants.
  6. Fertilization: Watermelons are heavy feeders and require regular fertilization. Apply a balanced fertilizer, such as a 10-10-10, before planting and again when the vines start to run. Avoid excessive nitrogen, as it can result in excessive foliage growth at the expense of fruit production.
  7. Pollination: Watermelons require pollination to set fruit. Bees are the primary pollinators, so encourage their presence by planting flowers that attract them nearby. If bee activity is limited, you can hand-pollinate by transferring pollen from the male flowers to the female flowers using a small brush or cotton swab.
  8. Pest and Disease Control: Monitor your watermelon plants regularly for pests like aphids, cucumber beetles, and squash bugs. Use organic pest control methods like handpicking, insecticidal soaps, or neem oil if necessary. Prevent diseases by providing good air circulation, avoiding overhead watering, and practicing crop rotation.
  9. Harvesting: Watermelons are ready to harvest when the fruit has reached full size, the bottom side turns yellow or cream-colored, and the tendrils near the stem start to dry out. Give the fruit a gentle tap – a hollow sound indicates ripeness. Cut the fruit from the vine using a sharp knife, leaving a short stem attached.

By following these steps and considerations, you can successfully grow watermelons and enjoy a bountiful harvest.

When to harvest

In Mississippi, watermelons are typically harvested from late June to early August. The exact timing may 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 maturity before harvesting. Some indicators of ripeness include a dull or matte appearance of the fruit’s skin, a yellow or creamy color on the underside where it touches 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 flavor and sweetness.

Common watermelon plant problems and fixes

Common problems when growing watermelon include:

  1. Poor germination: If the seeds fail to germinate, it may be due to low soil temperature or poor seed quality. To fix this, ensure that the soil temperature is consistently above 70°F (21°C) before planting. Additionally, purchase high-quality seeds from a reputable source.
  2. Lack of pollination: Watermelon plants require pollination for fruit set. If there is a lack of bees or other pollinators in your area, you can manually pollinate the flowers by transferring pollen from the male flowers to the female flowers using a small brush or cotton swab.
  3. Blossom end rot: This is a common problem characterized by a dark, sunken spot at the blossom end of the fruit. It is caused by calcium deficiency or inconsistent watering. To prevent blossom end rot, ensure the soil is well-drained and consistently moist. Adding calcium-rich amendments, such as crushed eggshells or agricultural lime, to the soil before planting can also help.
  4. Powdery mildew: This fungal disease appears as a white, powdery coating on the leaves. It thrives in humid conditions. To prevent powdery mildew, ensure good air circulation around the plants by spacing them properly. Avoid overhead watering and instead water at the base of the plants. If necessary, apply a fungicide labeled for powdery mildew control.
  5. Pest infestations: Common pests that attack watermelon plants include aphids, cucumber beetles, and squash bugs. Regularly inspect your plants for signs of pests and take appropriate measures to control them. This can include using insecticidal soaps, neem oil, or introducing beneficial insects like ladybugs or lacewings.
  6. Fruit splitting: Watermelon fruit can split if there is a sudden increase in water uptake or inconsistent watering. To prevent fruit splitting, ensure the plants receive consistent moisture throughout the growing season. Mulching around the plants can help retain soil moisture.
  7. Poor fruit quality: If the watermelon fruits are small, misshapen, or lacking sweetness, it may be due to inadequate pollination, nutrient deficiencies, or improper watering. Ensure proper pollination, provide adequate nutrients through regular fertilization, and maintain consistent soil moisture to improve fruit quality.

Remember to regularly monitor your watermelon plants for any signs of problems and take appropriate action promptly to ensure healthy growth and abundant fruit production.
