Best varieties of watermelon to grow in Wyoming
Watermelon varieties that grow best in Wyoming are those that have a shorter growing season and can tolerate cooler temperatures. Here are a few varieties that are known to perform well in Wyoming:
- ‘Blacktail Mountain’: This variety is an early-maturing watermelon that can be harvested in about 70-80 days. It has a small to medium size, with dark green skin and sweet red flesh.
- ‘Sugar Baby’: Another early-maturing variety, ‘Sugar Baby’ is a popular choice for cooler climates. It produces small to medium-sized melons with dark green skin and sweet, crisp red flesh.
- ‘Yellow Doll’: This variety is known for its early maturity and high sugar content. It produces small to medium-sized melons with yellow skin and sweet, juicy flesh.
- ‘Moon and Stars’: Although it takes a little longer to mature (around 90-100 days), ‘Moon and Stars’ is a unique variety that can thrive in Wyoming’s climate. It has dark green skin with yellow spots and is named after the yellow “moon” and smaller “stars” that can be found on the rind.
- ‘Early Moonbeam’: This variety is an early-maturing watermelon that can be harvested in about 70-80 days. It has a small to medium size, with light green skin and sweet red flesh.
When selecting watermelon varieties for Wyoming, it’s important to consider the average frost dates and the length of your growing season. Additionally, providing the plants with adequate protection, such as using row covers or planting in raised beds, can help extend the growing season and increase the chances of success.
When to plant watermelon in Wyoming
The best time to plant watermelon in Wyoming is typically in late spring or early summer, once the soil has warmed up and all danger of frost has passed. The average last frost date in Wyoming varies depending on the specific location, but it generally falls between mid-May to early June. It is important to ensure that the soil temperature is consistently above 60°F (15°C) before planting watermelon seeds or transplants.
How to grow
Growing watermelon requires careful planning and attention to detail. Here are the steps and considerations to keep in mind:
- Climate and Location: Watermelons thrive in warm climates with temperatures between 70-90°F (21-32°C). Choose a sunny location in your garden with well-drained soil.
- Soil Preparation: Watermelons prefer loamy soil with good drainage. Before planting, amend the soil with organic matter like compost or well-rotted manure to improve fertility and drainage.
- Seed Selection: Choose watermelon varieties that are suitable for your climate and growing conditions. Consider factors like size, taste, and disease resistance. Purchase high-quality seeds from a reputable source.
- Germination: Start watermelon seeds indoors 2-3 weeks before the last frost date or directly sow them in the garden after the danger of frost has passed. Germinate the seeds in seed trays or pots filled with seed-starting mix. Keep the soil consistently moist and maintain a temperature between 75-85°F (24-29°C) for optimal germination.
- Transplanting: Once the seedlings have developed a few true leaves and the soil has warmed up, transplant them into the garden. Space the plants 3-4 feet apart in rows that are 6-8 feet apart. Ensure the soil is well-watered before transplanting to minimize root disturbance.
- Watering: Watermelons require consistent moisture throughout their growing season. Provide deep, regular watering to keep the soil evenly moist but not waterlogged. Avoid overhead watering to prevent foliage diseases. Mulching around the plants can help retain soil moisture.
- Fertilization: Watermelons are heavy feeders. Apply a balanced fertilizer or compost before planting, and then side-dress with nitrogen-rich fertilizer when the vines start to run. Follow the instructions on the fertilizer package for proper application rates.
- Trellising and Support: Some watermelon varieties can be trained to grow on trellises or supports, which can save space and improve air circulation. Use soft ties to secure the vines to the trellis and regularly prune any excessive growth.
- Pollination: Watermelons require pollination for fruit set. Bees and other pollinators are attracted to the bright yellow flowers of watermelon plants. Avoid using pesticides that can harm pollinators.
- Pest and Disease Control: Monitor your plants regularly for common 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.
- Harvesting: Watermelons are ready for harvest when the tendrils near the fruit turn brown and dry, the bottom side turns yellow, and the fruit sounds hollow when tapped. Cut the fruit from the vine with 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 is typically harvested in Wyoming between late August and early September. The exact timing can vary depending on the specific variety of watermelon being grown and the local climate conditions. It is important to monitor the watermelon plants closely for signs of maturity before harvesting. Some indicators of readiness for harvest include a dull or matte appearance of the fruit’s skin, a yellow or cream-colored underside where the fruit touches the ground, and a hollow sound when tapped. Additionally, the tendril closest to the fruit should be dry and brown. Harvesting watermelon at the right time ensures optimal flavor and sweetness.
Common watermelon plant problems and fixes
Common problems when growing watermelon include:
- Poor pollination: Watermelon plants require proper pollination to produce fruit. If there are not enough bees or other pollinators in your garden, you can hand-pollinate the flowers using a small brush or cotton swab. Gently transfer pollen from the male flowers to the female flowers.
- Blossom end rot: This is a condition where the bottom end of the fruit turns black and rots. It is caused by calcium deficiency or irregular watering. To prevent blossom end rot, ensure consistent watering and add calcium-rich amendments to the soil before planting.
- Powdery mildew: Powdery mildew is a fungal disease that appears as a white powdery coating on the leaves. To prevent it, provide good air circulation by spacing plants adequately and avoid overhead watering. If powdery mildew appears, treat it with a fungicide or a homemade solution of diluted milk or baking soda.
- Insect pests: Common pests that attack watermelon plants include aphids, cucumber beetles, and squash bugs. Use insecticidal soaps or organic insecticides to control these pests. Additionally, planting companion plants like marigolds or using row covers can help deter pests.
- Watering issues: Watermelons require consistent moisture, especially during fruit development. Overwatering can lead to root rot, while underwatering can cause the fruit to be small or develop a bitter taste. Water deeply and regularly, providing about 1-2 inches of water per week.
- Lack of sunlight: Watermelon plants need full sun to thrive and produce sweet fruits. Ensure they receive at least 6-8 hours of direct sunlight daily. If your garden has shade, consider growing watermelons in containers that can be moved to sunnier spots.
- Improper fertilization: Watermelon plants require regular feeding with balanced fertilizers. Use a slow-release organic fertilizer or apply a liquid fertilizer every few weeks during the growing season. Avoid excessive nitrogen fertilization, as it can result in lush foliage but fewer fruits.
By addressing these common problems, you can increase your chances of successfully growing watermelons.
