How to grow giant watermelons 2016

Growing the biggest watermelon is a rewarding challenge that requires careful planning, dedication, and attention to detail. This comprehensive guide will provide you with the essential steps and techniques to maximize your chances of cultivating a record-breaking watermelon in your own backyard.

Choose the Right Watermelon Variety

Selecting the appropriate giant watermelon variety is the first and most crucial step in your pursuit of growing a colossal fruit. Popular varieties like Carolina Cross and Black Diamond have been specifically developed for their exceptional size potential. Here’s a table showcasing some of the top giant watermelon varieties, their average weights, and descriptions:

VarietyAverage WeightDescription

Carolina Cross	200-300 lbs	Known for its oblong shape and sweet, crisp flesh.
Black Diamond	150-250 lbs	Boasts a dark green rind and juicy, deep red flesh.
Crimson Sweet	150-250 lbs	Renowned for its excellent flavor and disease resistance.
Golden Midget	100-150 lbs	Unique yellow rind and sweet, yellow flesh.
Congo	200-300 lbs	Produces massive, elongated fruits with a tough rind.

Before making your selection, it’s crucial to understand watermelon growth habits. Some varieties have longer vines that require more space, while others produce more compact plants. Additionally, consider the size of the mature fruit, as larger varieties may need extra support or trellising.

When choosing your watermelon variety, also factor in your growing zone and climate. Certain varieties thrive better in specific regions, so research which ones are best suited for your area to optimize your chances of success.

Prepare the Soil for Maximum Growth

Proper soil preparation is essential for promoting robust plant growth and supporting the development of massive watermelons. Start by conducting a soil test to determine the pH level, nutrient content, and any necessary amendments.

Watermelons thrive in well-draining, nutrient-rich soil with a pH range of 6.0 to 6.8. If your soil test reveals deficiencies or imbalances, amend the soil accordingly with lime, sulfur, or fertilizers to achieve the desired pH and nutrient levels.

Building raised beds or hills can significantly improve drainage and soil warmth, both of which are crucial for watermelon growth. Raised beds also make it easier to manage weeds and provide better air circulation around the plants.

Incorporating organic matter, such as compost or aged manure, is highly recommended. These materials not only enrich the soil with essential nutrients but also improve water retention and soil structure, creating an ideal environment for your watermelon plants to flourish.

Planting and Care for Giant Watermelons

Once you’ve prepared the soil, it’s time to plant your watermelon seeds or seedlings. You can either direct sow seeds or transplant seedlings, depending on your preference and growing season.

• Direct Sowing: Plant seeds directly into the ground after the last frost date, spacing them 6-12 inches apart and 1-2 inches deep. This method allows the roots to establish themselves without disturbance.
• Transplanting: Start seeds indoors 4-6 weeks before the last frost date, and transplant the seedlings into the prepared beds once the soil has warmed up and the risk of frost has passed.

Proper spacing and support are vital for giant watermelon cultivation. Space plants 6-8 feet apart in rows, or create hills spaced 8-10 feet apart in all directions. As the vines grow, provide support with trellises, stakes, or a sturdy cage to prevent damage and promote air circulation.

Water your watermelon plants consistently, ensuring the soil remains moist but not waterlogged. Overwatering can lead to root rot, while underwatering can stunt growth and affect fruit size. Aim to provide 1-2 inches of water per week, adjusting as needed based on weather conditions.

Fertilize your watermelon plants regularly, following a balanced fertilizer program. A typical fertilizer ratio for watermelons is 10-10-10 (nitrogen-phosphorus-potassium). Here’s a recommended fertilizer application schedule:

Growth StageFertilizer Application

Seedling Stage	Apply a balanced, water-soluble fertilizer every 2 weeks.
Vine Growth Stage	Switch to a high-phosphorus fertilizer every 4 weeks.
Fruit Development Stage	Use a high-potassium fertilizer every 2-3 weeks.

Pollination and Fruit Set

Proper pollination is crucial for successful fruit set and the development of giant watermelons. While watermelons rely on bees for natural pollination, you can also employ hand pollination techniques to ensure optimal fruit production.

Hand pollination involves transferring pollen from the male (staminate) flowers to the female (pistillate) flowers using a small brush or cotton swab. This process should be done in the morning when the flowers are fully open.

Additionally, thinning and pruning your watermelon vines can help direct the plant’s energy towards the remaining fruits, promoting larger sizes. Once the fruits have formed, remove any underdeveloped or misshapen fruits, leaving only the healthiest and most promising ones to mature.

Troubleshooting Common Issues

Even with the best efforts, growing giant watermelons can present some challenges. Being proactive and addressing common issues promptly is essential for a successful harvest.

• Pests and Diseases: Monitor your plants regularly for signs of pests like aphids, cucumber beetles, or diseases such as powdery mildew or fusarium wilt. Implement integrated pest management strategies, including cultural controls, biological controls, and targeted pesticide applications as a last resort.
• Environmental Challenges:
  • Excessive Heat: Provide shade for your watermelon plants during the hottest parts of the day, and maintain consistent soil moisture to prevent heat stress.
  • Drought: Mulch your plants heavily to retain soil moisture, and consider installing a drip irrigation system for efficient watering.
  • Heavy Rainfall: Ensure proper drainage to prevent waterlogged conditions, which can lead to root rot and other issues.

By proactively addressing these challenges, you can minimize their impact on your watermelon crop and increase your chances of growing record-breaking fruits.

Harvesting and Storing Giant Watermelons

As your watermelons approach maturity, keep a close eye on them and watch for signs of ripeness. These include:

• A dull, creamy underside where the fruit rests on the ground
• A hollow sound when tapped
• A slight browning of the tendril closest to the fruit
• Resistance when trying to insert your thumbnail into the rind

When harvesting your giant watermelons, exercise caution and employ proper techniques to avoid injury or damage to the fruits. Use a sharp knife or pruners to cut the stem, leaving a few inches attached to the fruit. Gently roll or lift the watermelon onto a tarp or wheelbarrow for transportation.

To extend the shelf life of your giant watermelons, store them in a cool, dry place, ideally between 55-60°F (12-15°C). Avoid exposing them to direct sunlight or extreme temperatures, which can accelerate spoilage. With proper storage, your watermelons can remain fresh for several weeks.

Conclusion

Growing the biggest watermelon is an exciting and rewarding endeavor that requires patience, dedication, and attention to detail. By following the steps outlined in this guide, from selecting the right variety to proper soil preparation, planting, care, pollination, and harvesting techniques, you’ll be well on your way to cultivating a record-breaking watermelon in your own backyard. Embrace the challenge, enjoy the process, and revel in the satisfaction of producing a truly colossal fruit that will be the envy of your neighborhood.
