Allsweet Watermelon: A Sweet Choice

Allsweet watermelon is a popular variety known for its exceptional sweetness and vibrant red flesh. It’s also relatively easy to grow, making it a great choice for both beginner and experienced gardeners alike.

Choosing the Right Spot and Soil

Watermelon thrives in warm, sunny conditions. Choose a spot in your garden that receives at least six hours of direct sunlight daily. The ideal soil should be well-drained, loose, and rich in organic matter.

Soil Preparation:

  • Test your soil: Before planting, it’s a good idea to test your soil’s pH. Watermelons prefer a slightly acidic to neutral pH (6.0-6.5). If your soil is too acidic, you can amend it with lime.
  • Amend your soil: To improve drainage and add nutrients, work in a generous amount of compost or well-rotted manure before planting.

Planting Your Allsweet Watermelon Seeds

Timing:

  • Direct Sowing: Watermelon seeds can be directly sown outdoors after the last frost has passed and the soil temperature has warmed to at least 70°F (21°C). This is typically around late spring or early summer, depending on your region.
  • Starting Seeds Indoors: You can also start your watermelon seeds indoors 3-4 weeks before the last frost date. This gives them a head start and ensures faster germination.

Planting Process:

1. Spacing: Space your seeds 2-3 feet apart in rows that are 4-5 feet apart.
2. Depth: Plant seeds 1 inch deep.
3. Watering: Water thoroughly after planting. Keep the soil consistently moist, but not soggy, until germination occurs.

Caring for Your Watermelon Vines

Watering:

  • Consistent Moisture: Watermelons require consistent moisture, especially during the first few weeks after planting. Water deeply and infrequently, rather than shallowly and frequently.
  • Mulch: Apply a layer of mulch around your watermelon plants to help retain moisture and suppress weeds.

Fertilizing:

  • Balanced Fertilizer: Watermelons are heavy feeders, so a balanced fertilizer like 10-10-10 can be applied every 4-6 weeks.
  • Side Dressing: You can also side dress your plants with compost or manure throughout the growing season.

Weeding:

  • Regular Weeding: Keep your watermelon patch free of weeds, as they compete with your plants for nutrients and water.

Trellising:

  • Support: If you’re growing your watermelons in a small space or have limited ground space, consider using a trellis to support the vines. This will help keep the fruit off the ground and prevent rot.

Harvesting Your Sweet Treats

Signs of Ripeness:

  • Color: The watermelon rind will turn from dark green to a dull, lighter green, sometimes with a slight yellowing.
  • Sound: When you tap the watermelon, it will produce a dull, hollow sound.
  • Stem: The stem will dry up and detach easily from the fruit.

Harvesting:

  • Cut Carefully: Use a sharp knife to cut the watermelon from the vine. Avoid pulling or twisting the fruit.

Enjoying Your Homegrown Watermelon

Once you’ve harvested your Allsweet watermelon, it’s time to enjoy the fruits of your labor! Cut it open and savor the juicy, sweet flavor. You can also use it in salads, smoothies, or other recipes.

Beyond the Harvest: Tips for Next Year

  • Save Seeds: If you want to grow Allsweet watermelon again next year, you can save seeds from your harvested fruit. Choose the best-looking melons and let them dry completely before extracting the seeds.
  • Rotate Crops: To prevent soilborne diseases, rotate your watermelon crops with other plants each year.
  • Prepare for Next Season: After harvesting, clean up any plant debris and prepare your garden bed for the next planting season.
