Choosing Watermelons by Looking at the Color of the Field Spot

Observing the color at the bottom of a watermelon can tell you a lot about whether the fruit is sweet and ripe. This simple yet effective trick is widely used by farmers and fruit vendors to determine quality before cutting the fruit open.

Health Benefits of Watermelon

The bright red color of watermelon flesh comes from lycopene, a powerful antioxidant known for its impressive health benefits. According to WebMD, numerous studies have shown that lycopene may help reduce the risk of cancer, type 2 diabetes, and other chronic conditions. Lycopene also has anti-inflammatory properties that support overall cellular health.

Interestingly, watermelon contains more lycopene than tomatoes, making it one of the best natural sources of this nutrient. If you want to increase your lycopene intake, choose watermelons with deep red flesh rather than those with orange or pale hues. Seedless watermelons also tend to have higher lycopene levels than seeded varieties.

In addition to lycopene, watermelon provides a natural form of sun protection. While it cannot replace sunscreen, consuming watermelon regularly may help reduce skin damage caused by UV rays and slow down the skin-aging process.

Watermelon is also rich in citrulline, an amino acid that promotes better blood flow, supports heart health, and may help lower blood pressure. The fruit is packed with vitamin A, which is essential for maintaining healthy vision, supporting immunity, and keeping the skin moisturized. It also contains vitamins C and B6, making watermelon a refreshing and nutritious choice on hot days.

Beyond hydration, the high water content in watermelon helps flush toxins out of the body, supports kidney function, and aids digestion. All these benefits make watermelon not only delicious but also a valuable addition to a healthy diet.

Tips for Choosing a Sweet, Ripe Watermelon

1. Check the Field Spot (the Bottom of the Watermelon)

The field spot is the area where the watermelon rested on the ground while growing. A high-quality watermelon typically has a creamy yellow or deep yellow-orange field spot. In some cases, it may even appear slightly brownish—this is a strong sign that the fruit is ripe and sweet.

If the field spot is white or very pale, the watermelon was harvested too early and will likely be less flavorful.

2. Look at the Stem, Top, and Navel of the Watermelon

After examining the bottom, flip the watermelon over to check the stem (or where the stem used to be). A good watermelon usually has a small, dry, curled stem that remains firmly attached. This indicates the fruit ripened naturally on the vine.

If the stem is still large, green, or stiff, the watermelon was picked too early and will need more time to ripen.

If the watermelon no longer has a stem, observe the top (blossom end) or navel.

• For round watermelons: the deeper the indentation, the sweeter and more flavorful the fruit.

• For oblong watermelons: the indentation should be moderate. A very deep one may indicate that the fruit is overripe, with mushy flesh inside.

3. Examine the Shape

The shape of a watermelon often depends on its variety. Generally:

• Oblong (long) watermelons tend to be juicier and sweeter.

• Round ones are usually crisp and firm.

However, some varieties naturally grow in only one shape, so this method is not always absolute. Still, perfectly symmetrical fruits—regardless of shape—are usually of better quality than those with unusual bumps or dents.

4. Inspect the Rind

Finally, look at the overall appearance of the rind. A ripe watermelon typically has:

• A smooth, glossy surface

• Bold and clearly defined stripes

• A uniform pattern

If the rind is dark with shiny blackish tones, that is also a good indicator of ripeness. Check for brown webbing or sugar scars on the surface. These marks are caused by bees pollinating the flower; more pollination usually means the fruit developed more sweetness.

Avoid watermelons with soft spots, cracks, or dull, lifeless skin, as these may indicate internal damage or overripeness.
