Best varieties of watermelon to grow in Tennessee
In Tennessee, there are several watermelon varieties that are well-suited for growing in the region’s climate. Here are a few popular choices:
- Crimson Sweet: This variety is a favorite among gardeners in Tennessee. It produces large, round melons with deep red, sweet flesh. Crimson Sweet is known for its excellent flavor and high sugar content.
- Charleston Gray: Another popular variety in Tennessee, Charleston Gray produces large, oblong melons with light green skin and sweet, juicy flesh. It is a heat-tolerant variety that performs well in hot summer conditions.
- Sugar Baby: If you have limited space or are looking for a smaller watermelon variety, Sugar Baby is a great option. It produces small, round melons with dark green skin and sweet, crisp flesh. Sugar Baby is an early-maturing variety, making it ideal for Tennessee’s shorter growing season.
- Jubilee: Jubilee watermelons are known for their large size and sweet, juicy flesh. They have a thick, light green rind with dark green stripes. Jubilee is a popular choice for home gardeners and is well-adapted to Tennessee’s climate.
- Moon and Stars: This heirloom variety is known for its unique appearance. Moon and Stars watermelons have dark green skin with small, yellow “stars” and a larger, yellow “moon” on the rind. The flesh is sweet and juicy. While it requires a longer growing season, it can be successfully grown in Tennessee with proper care.
Remember, when selecting watermelon varieties for Tennessee, it’s important to consider factors such as disease resistance, heat tolerance, and days to maturity to ensure a successful harvest.
When to plant watermelon in Tennessee
The best time to plant watermelon in Tennessee is typically in late spring or early summer, when the soil temperature has reached at least 70°F (21°C). This usually falls between mid-April and mid-May. Watermelons are warm-season crops that require a long growing season, so it’s important to ensure that the danger of frost has passed before planting.
How to grow
Growing watermelon requires careful planning and attention to detail. Here are the steps and considerations to keep in mind:
- Climate and Soil: Watermelons thrive in warm climates with temperatures between 70-90°F (21-32°C). Choose a sunny location with well-draining soil. The soil should be rich in organic matter and have a pH level between 6.0-6.8.
- Seed Selection: Choose watermelon seeds suitable for your climate and desired variety. There are different types, such as seeded or seedless, and various sizes and colors available.
- Starting Seeds: Start watermelon seeds indoors 3-4 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 consistently moist and provide warmth and light until the seedlings emerge.
- Transplanting: Once the danger of frost has passed and the soil temperature reaches 70°F (21°C), transplant the seedlings into the garden. Space the plants 3-4 feet apart in rows that are 6-8 feet apart.
- Watering: Watermelons require consistent watering throughout their growth cycle. Provide deep watering, ensuring the soil is evenly moist but not waterlogged. Avoid overhead watering to prevent leaf diseases. Mulching around the plants helps retain moisture and suppress weeds.
- Fertilization: Watermelons are heavy feeders. Before planting, incorporate compost or well-rotted manure into the soil. Once the plants start to vine, apply a balanced fertilizer every 3-4 weeks. Avoid excessive nitrogen, as it can result in excessive foliage growth and fewer fruits.
- Pollination: Watermelon flowers require pollination to set fruit. Bees and other pollinators are crucial for this process. To attract pollinators, avoid using pesticides harmful to bees and provide a diverse range of flowering plants nearby.
- Pruning and Training: Watermelon vines can become sprawling, so consider trellising or training them to save space and improve airflow. Prune off excessive foliage and side shoots to redirect energy towards fruit production.
- Pest and Disease Management: Common pests that affect watermelons include aphids, cucumber beetles, and squash bugs. Monitor plants regularly and take appropriate measures, such as using insecticidal soap or organic pest control methods. Diseases like powdery mildew and fusarium wilt can be prevented by providing good air circulation and avoiding overhead watering.
- Harvesting: Harvest watermelons when they are fully ripe. Look for signs like a dull skin color, a yellow or brown dried tendril near the fruit stem, and a hollow sound when tapped. Cut the fruit from the vine, 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 should be harvested in Tennessee when they are fully ripe. The exact timing can vary depending on the specific variety of watermelon you are growing and the weather conditions during the growing season. However, as a general guideline, watermelons are typically ready for harvest about 80-90 days after planting.
To determine if a watermelon is ready for harvest, there are a few signs to look for:
- Thumping: Gently tap the watermelon with your knuckles. If it produces a deep, hollow sound, it is likely ripe. If it sounds dull or solid, it may need more time to mature.
- Color: Look at the color of the watermelon’s skin. Most watermelons will have a dull or matte appearance when they are ripe, rather than a shiny or glossy look. Additionally, the underside of the watermelon (where it rests on the ground) should have a yellowish or creamy color.
- Tendril drying: Check the tendril closest to the watermelon stem. If it is dry and brown, it is a good indication that the watermelon is ripe.
- Size and shape: Watermelons should reach their mature size and have a uniform shape. The skin should be firm and resistant to pressure.
It’s important to note that watermelons do not continue to ripen after they are harvested, so it’s crucial to pick them at the right time for optimal flavor and sweetness.
Common watermelon plant problems and fixes
Common problems when growing watermelon include:
- Poor pollination: Watermelon plants require proper pollination to set fruit. If you notice a lack of fruit development, 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.
- Blossom end rot: This is a condition where the bottom end of the fruit becomes sunken, dark, and leathery. It is caused by calcium deficiency or irregular watering. To prevent blossom end rot, ensure consistent watering and provide adequate calcium through soil amendments or foliar sprays.
- 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, avoid overhead watering, and apply fungicides if necessary.
- Pest infestation: Common pests that attack watermelon plants include aphids, cucumber beetles, and spider mites. Use insecticidal soaps, neem oil, or other organic insecticides to control these pests. Additionally, practicing crop rotation and removing plant debris can help prevent pest infestations.
- Overwatering or underwatering: Watermelon plants require consistent moisture, but overwatering or underwatering can lead to problems. Overwatering can cause root rot, while underwatering can result in poor fruit development. Water the plants deeply and regularly, ensuring the soil is moist but not waterlogged.
- Fruit splitting: Watermelon fruits may split due to rapid growth or fluctuations in moisture levels. To prevent fruit splitting, maintain consistent moisture levels by watering regularly and mulching around the plants to retain soil moisture.
- Lack of sweetness: Watermelon fruits may lack sweetness if they are harvested too early or if the plants are not receiving enough sunlight. Ensure that the fruits are fully ripe before harvesting, and provide at least 6-8 hours of direct sunlight daily for optimal sugar development.
Remember, prevention is key in maintaining healthy watermelon plants. Regularly inspect your plants for signs of pests, diseases, or nutrient deficiencies, and take appropriate action to address any issues promptly.
