Watermelon is a refreshing and delicious fruit that many people enjoy during the summer months. However, sometimes when you cut into a watermelon, you may notice that the inside is white instead of the expected vibrant pink or red color. This can be a confusing and disappointing experience, especially if you were looking forward to enjoying a sweet and juicy watermelon.
There are several reasons why a watermelon may be white inside. One possible explanation is that the fruit was not allowed to fully ripen before it was harvested. Watermelons that are picked too early may not develop the full color and sweetness that is characteristic of a ripe watermelon. Another possibility is that the watermelon was grown in a cooler climate, which can affect the fruit’s color and flavor. Finally, some varieties of watermelon are naturally white or yellow inside, so it is possible that you simply purchased a different type of watermelon than you were expecting.

Understanding Watermelon Varieties
Watermelons come in a variety of types, each with its unique characteristics. The two primary types of watermelons are the red-fleshed and white-fleshed watermelons. The red-fleshed watermelon is the most common type and has a delicious red interior. The white-fleshed watermelon, on the other hand, has a white interior and is less common.
There are several varieties of watermelons, and each has its unique characteristics. Some of the most common watermelon varieties include:
- Crimson Sweet: This is a popular variety of red-fleshed watermelon with a sweet flavor and crisp texture.
- Charleston Gray: This variety has a large, oblong shape and a light green exterior. The flesh is red and has a sweet flavor.
- Sugar Baby: This is a small, round watermelon with a dark green exterior and a sweet red interior.
- Moon and Stars: This variety has a dark green exterior with yellow “stars” and “moons.” The flesh is red and has a sweet flavor.
White-fleshed watermelons also come in several varieties, including:
- Cream of Saskatchewan: This is a small, round watermelon with a creamy white interior and a sweet flavor.
- Ice Box: This variety has a small size and a white interior with a sweet flavor.
- Mountain Sweet Yellow: This variety has a yellow exterior and a white interior with a sweet flavor.
It is essential to note that not all white watermelons have white flesh. Some white-fleshed watermelons have a light green or yellow exterior and a white interior. Citrullus lanatus is the scientific name for watermelons, and it is the same for both red and white-fleshed varieties.
Indications of Ripeness
When it comes to determining whether a watermelon is ripe, there are a few key indicators to look out for. These include the color of the fruit, the condition of the vine, the sound it makes when tapped, and the appearance of the field spot.
Firstly, the color of a ripe watermelon is typically a deep, uniform shade of red or pink, depending on the variety. If the fruit is still green or has pale yellow patches, it may not be fully ripe yet. However, some watermelon varieties, such as the Cream of Saskatchewan, have a white or pale green interior even when fully ripe.
Another indication of ripeness is the condition of the vine. If the vine is still green and healthy-looking, this suggests that the watermelon is not yet ripe. On the other hand, if the vine is brown and withered, this may indicate that the fruit is overripe or has been left on the vine for too long.
When tapping a watermelon, a ripe fruit should produce a hollow sound. If the sound is dull or flat, this may indicate that the fruit is not yet ripe or has started to spoil. It’s important to note that tapping a watermelon is not always a reliable method of determining ripeness, as some varieties may produce different sounds depending on their size and thickness.
Finally, the appearance of the field spot can also be an indication of ripeness. The field spot is the area on the underside of the watermelon where it has rested on the ground. A ripe watermelon should have a creamy, yellowish-brown field spot. If the spot is white or green, this suggests that the fruit is not yet ripe.
In summary, there are several indicators of ripeness to look out for when selecting a watermelon. By paying attention to the color, condition of the vine, sound when tapped, and appearance of the field spot, you can increase your chances of selecting a ripe and delicious fruit.
Why Watermelon Turns White Inside
Watermelon is a refreshing and delicious fruit that is enjoyed by many people around the world. However, sometimes when you cut open a watermelon, you may notice that the flesh is white instead of the expected pink or red. This can be a bit confusing and concerning, especially if you are not sure what is causing the discoloration. In this section, we will explore why watermelon turns white inside and what it means for the fruit.
One of the main reasons why watermelon turns white inside is due to a lack of chlorophyll. Chlorophyll is a green pigment that is present in most fruits and vegetables and is responsible for the plant’s ability to convert sunlight into energy through photosynthesis. When a watermelon does not have enough chlorophyll, the flesh may appear white instead of the expected pink or red. This can happen if the watermelon was not exposed to enough sunlight during its growth or if it was harvested too early.
Another reason why watermelon may turn white inside is due to a lack of ripeness. Watermelons continue to ripen after they are harvested, and if they are not left to ripen fully, the flesh may not develop its characteristic color. In some cases, white streaks or patches may appear in an otherwise pink or red watermelon, which can be an indication of uneven ripening.
Finally, watermelon may turn white inside due to disease or other issues. For example, a fungal infection called Fusarium wilt can cause watermelon to develop white streaks or discoloration. Similarly, if a watermelon is stored in a damp or humid environment, it may develop mold or other types of fungal growth, which can cause it to turn white or discolored.
In conclusion, there are several reasons why watermelon may turn white inside, including a lack of chlorophyll, under-ripeness, and disease. While white flesh may not be visually appealing, it does not necessarily mean that the watermelon is unsafe to eat. However, if you notice any signs of mold or other types of fungal growth, it is best to discard the fruit to avoid any potential health risks.
Growing Conditions and Their Impact
The growing conditions of watermelons can greatly impact the quality and color of the fruit. Melons that are grown in ideal conditions tend to have a vibrant red color, while those grown in less than ideal conditions may have a white or pale pink color on the inside.
Growing watermelons in the right conditions is essential to ensure that the fruit develops properly. Environmental conditions such as temperature, rainfall, and soil quality can all impact the growth and development of watermelons. For example, watermelons prefer warm temperatures between 75 and 85 degrees Fahrenheit, and require at least 6 hours of sunlight per day to develop properly.
Over-watering or over-feeding watermelon plants can lead to a lack of sugar production in the fruit, which can result in a white or pale pink color on the inside. It is important to ensure that the soil is well-drained and not waterlogged, and that the plants are not over-fertilized.
Additionally, the underside of the watermelon should be monitored to ensure that it is not resting on wet soil or damp vegetation, as this can lead to rotting and discoloration of the fruit.
In summary, growing watermelons in the right conditions is crucial to ensuring that the fruit develops properly and has a vibrant red color on the inside. Environmental conditions, sunlight, over-watering, over-feeding, and monitoring the underside of the fruit are all important factors to consider when growing watermelons.
Role of Cross-Pollination
Cross-pollination is a process in which the pollen from one plant is transferred to the stigma of another plant of the same species. This process is essential for the production of fruits and vegetables, including watermelons. In the case of watermelons, cross-pollination occurs when bees or other insects transfer pollen from the male flower to the female flower.
Bees play a crucial role in cross-pollination as they are the primary pollinators of watermelon plants. When bees collect nectar from the flowers, they transfer pollen from the male flower to the female flower, resulting in the fertilization of the ovules. Without bees, watermelon plants would have a reduced chance of cross-pollination, which could lead to the production of seedless or white-fleshed watermelons.
Genetics also play a role in the color of the watermelon flesh. Some watermelon varieties have genes that produce white or yellow flesh, while others produce red or pink flesh. However, cross-pollination can also affect the color of the watermelon flesh. If a watermelon plant with white or yellow flesh is cross-pollinated with a plant that produces red or pink flesh, the resulting fruit may have a different color than the parent plants.
In conclusion, cross-pollination is crucial for the production of watermelon fruits, and bees play a vital role in this process. Genetics also play a role in the color of the watermelon flesh, but cross-pollination can affect the color of the fruit as well.
Watermelon Diseases and Disorders
Watermelons are susceptible to various diseases and disorders that can affect their growth and development. Some of the common diseases and disorders that can cause white flesh in watermelons are:
Fusarium Wilt
Fusarium wilt is a fungal disease that affects the roots of watermelon plants. It can cause the leaves of the plant to wilt and turn yellow, and the fruit to develop white streaks or patches on the flesh. The fungus can survive in the soil for several years and can be spread by infected seeds, soil, or water.
Anthracnose
Anthracnose is a fungal disease that can affect all parts of the watermelon plant, including the fruit. It can cause the fruit to develop white, sunken lesions on the flesh, which can eventually turn brown and become covered in a pinkish mold. The fungus can be spread by rain, wind, and insects.
Gummy Stem Blight
Gummy stem blight is a fungal disease that affects the stems and leaves of watermelon plants. It can cause the stems to become gummy and the leaves to turn yellow and wilt. The fruit can develop white, sunken lesions on the flesh, which can eventually turn brown and become covered in a white, powdery mold. The fungus can be spread by infected seeds, soil, or water.
Blossom End Rot
Blossom end rot is a disorder that can affect the fruit of watermelon plants. It is caused by a calcium deficiency in the plant, which can result in the fruit developing white, sunken lesions on the blossom end. The disorder can be caused by irregular watering, high temperatures, or low soil pH.
Immature Watermelon
Sometimes, the white flesh in a watermelon is simply a result of the fruit being immature. If a watermelon is picked too early, it may not have had enough time to develop its full color and sweetness, resulting in white or pale flesh. It is important to wait until a watermelon is fully ripe before harvesting it to ensure the best flavor and texture.
Nutritional Value of White Watermelon
White watermelon, also known as icebox watermelon, may look different from the typical red-fleshed watermelon, but it still offers a variety of nutrients and health benefits. Here is a breakdown of the nutritional value of white watermelon:
Nutrients
White watermelon contains several essential vitamins and minerals, including vitamin C, vitamin A, potassium, and magnesium.
