Most of us are familiar with the popular fruit, watermelon. The bright red flesh and black seeds make for some sweet, juicy eating and fun seed spitting. But are yellow watermelons natural? With over 1,200 varieties of watermelon on the market today, from seedless to pink to black rinded, it should be no surprise that, yes, even yellow fleshed types are available.
Yellow flesh on your watermelon might come as quite a surprise since the exterior doesn’t look any different than the red variety. The flesh of watermelons turning yellow is a natural mutation. In fact, the originator of our commercial variety, which comes from Africa, is a yellow- to white-fleshed fruit. The fruit has a sweeter, honey-like flavor as compared to red-fleshed melons, but many of the same nutritional benefits. Yellow watermelon fruit is now widely available and a fun alternative to traditional watermelons.
Produce shopping is more fun than ever when purple kale, orange cauliflower and blue potatoes frequent the produce aisle. Many of these foods have been manipulated and bred to produce their outrageous colors but yellow watermelon fruit is different. There are many naturally occurring hues of melons.
These plants hybridize easily with each other and produce some unique forms and colors, with a wide range of flavors and sizes. A large field of melons may find that some watermelon is yellow inside, while other plants are producing red fruits. Once discovered, someone is going to maximize on the difference, collect seed and, voila, a new hued melon is born.
So you are now sold and want to try a crop of your own? Yellow watermelon seeds are available from reputable seed merchants. Their growing conditions are the same as a red melon and there are several varieties from which to choose. Some varieties to opt for might be:
The original fruits, Citrullus lanatus, have become a botanist’s playground, with the flavor and flesh the primary characteristics, while size and rind color may be manipulated. If your watermelon is yellow inside, chances are it is a derivative of the parent and has been carefully bred to enhance certain other traits.
Watermelon is a hot season fruit that requires well-drained soil with plenty of organic matter in full sun. Yellow watermelons need consistent moisture until fruit is the size of a tennis ball. Thereafter, water when soil is dry several inches down. A week before the fruit is ripe, withhold water to intensify the sugar in the flesh.
These plants need plenty of room to spread. Space 60 inches (152 cm.) apart and avoid overhead watering, which can cause foliar diseases. Harvest your yellow melons when the rind becomes dull green and a good rap on the fruit results in a dull thud. Store melons for up to 3 weeks in a cool area.
Now that you know how to grow yellow watermelons, enjoy their golden fruits as a fun surprise to spring on friends and family.

When ripe, the color of the rind should be a creamy yellow rather than green, and the rind will become smooth and waxy rather than dusky. If you press on the bottom of a ripe honeydew (the opposite end from where it’s attached to the vine ), it should feel slightly soft or at least a little springy.
Planting a few watermelon (Citrullus lanatus) vines in your garden lets you grow your own desserts or sweet snacks. This member of the Cucurbitaceae family is related to squash and pumpkins. As a tender annual, watermelon vines will not last through winter conditions and will require re-planting each spring.
Yellow watermelons contain many of the same nutritional properties as normal red watermelon, with some notable differences. Recent research suggests that these watermelons contain high levels of vitamin A and vitamin C – 18 percent and 21 percent of your daily requirements, respectively, in each cup of this fruit. There are less than 50 calories in a one-cup serving, as well as moderate amounts of potassium and sodium. While red watermelon is high in lycopene, yellow-colored watermelons are high in beta- carotene , another very powerful antioxidant often found in sweet potatoes and carrots.

Trying something new spices up life. You may have gardened for just a few years or all your life. If you’ve gotten in a rut by growing the same fruits and vegetables every year, try planting yellow watermelon, which isn't usually found in grocery stores. Most people have never even tried it. You will be delighted with the sweet honey-like flavor. Yellow watermelon is planted and cared for in the same manner as red-fleshed watermelon. It is, however, a hybrid (genetically altered). If you save the seeds to plant next year, you most likely will not get the same shape or flavor of fruit. In fact, many times the seed will not germinate, or if it does, will not produce.
Start your yellow watermelon seeds indoors. Watermelons are long-growing-season crops, harvested from 70 to 100 days from seeding. By starting your seeds indoors, you shave off as much as three weeks off the outdoor growing time.
Fill peat pots with commercial potting soil up to ¼ inch from the top. Mist the soil and stir it around to moisten.
Make three holes, with your finger, ½ to ¾ inch deep. Drop a yellow watermelon seed in each and cover, gently, with soil. If your seed packet directions suggest planting at an alternate depth, follow those directions. Every seed variety is different.
Place your peat pots into a metal or plastic tray. Add 1 qt. water to the bottom. The peat pots will draw the water up into the soil. Spray top of soil with a water mister, just to moisten. Place a sheet of clear plastic wrap over the pots on the tray to keep in the warmth. Place in a sunny window.
Remove the sheet of plastic wrap after the seeds germinate (when green sprouts pop out of the soil). Continue to mist the tops, keeping the soil moist. When you pick up a peat pot and it feels light, add 1 qt. water to the bottom of the tray.
Transplant the yellow watermelon seedlings when they are 2 to 3 inches tall and the last frost has passed in your location. Add compost to your garden soil for nutrients. Work the soil into mounds, 2 feet wide and spaced 6 feet apart. Use your hoe to create a mote around the mound for watering.
Dig a hole at the top of the mound, with a trowel, at the depth of the peat pot in a full-sun location. Drop the peat pot in the hole and gently move the soil around the sides, making sure the entire pot is covered. Peat pots are biodegradable, so you don't need to remove the seedling from the pot.
Fertilize your yellow watermelon plants every two weeks with a high-nitrogen fertilizer. When the blooms appear, switch to a high-phosphorus and potassium fertilizer. Add the fertilizer to the motes when you water. Water through the season about once a week.
Harvest your yellow watermelons. Use a combination of indications for ripeness: The green curly tendrils, close to the melon, turn brown, the rind color turns dull and hard and the bottom (touching the ground) turns light green or yellow. Use a hand clipper to cut the melon off at the stem.
Popular yellow watermelons include baby yellow, yellow doll and honey heart.
