If you have developed an interest in growing watermelons, you may have discovered that they grow differently from most fruits and vegetables. They require a long duration of warm weather, and they are grown in a particular form of soil. Through your research, you may come across an interesting method of growing watermelons and are curious about whether or not it’s true. Can watermelons grow in sand?

Yes, watermelons grow best in sandy soil. There are specific types of watermelon that can grow in pure desert sand, but the most common watermelons need a good mixture of sand and clay to survive and grow to their full potential.

What Type Of Soil Is Best For Watermelons?

Watermelons grow best in a sandy mixture of soil. It should also contain an adequate amount of clay and silt. Too much clay and silt, however, can cause clogging. The most important thing to know when preparing soil for watermelon plants is that it must drain correctly.

Sand and other organic matter will allow the soil to do so. Without proper drainage, a heavy rain or an abundance of water will puddle towards the roots of the watermelon plants and can cause root rot. You must also have a large amount of well composed soil for watermelon vines to develop and sprawl out. It is recommended that each plant has at least 20 square feet to grow.

When it comes to the nutrients in the soil, watermelons are heavy feeders, meaning they require a large number of nutrients to grow and thrive. Most gardeners recommend a slow release fertilizer that is well balanced with various nutrients. Lastly, the soil temperature must be warmed to 70 degrees Fahrenheit to be truly ready to grow watermelon plants

How To Adjust Soil To Be More Suited To Watermelon Growth

How To Adjust Soil To Be More Suited To Watermelon Growth

  • Purchase a pH test kit at your local home and gardening store or online and test the soil you are planting your watermelons in. The pH of your soil should be between 6.0 and 6.5 to be adequate for producing watermelons. If your soil’s pH is off, purchase a fertilizer to supply it with more nutrients.
  • Your soil must properly drain water to prevent root rotting, which easily occurs in watermelon plants. Your soil should be easily clumped into a ball. If it is, then it’s not draining enough. Try adding different types of earthly matter into your soil. This could include leaves, grass clippings, wood chips, more sand, or small rocks. 
  • Pack your soil full of nutrients by adding well aged and rotted compost or manure to it. The best time to prepare your soil with aged matter is in the fall and spring.
