Where is watermelon from?

The reddish-pink color of a watermelon is reminiscent of the heat of summer days and picnics with the family. But people are starting to replace the nostalgic red watermelon with a trendier and more unique watermelon bearing a similar green rind but with a bright yellow inside. So, what exactly is yellow watermelon, and how does it differ from the common red watermelon?

Red vs Yellow Watermelon

Caroline Ingalls

Yellow watermelons lack lycopene, which is the chemical that produces a reddish color in fruits and vegetables like tomatoes and red grapefruit. While the large amounts of lycopene in red watermelon give it a pinkish-red inside, the lack of lycopene in yellow watermelon yields a yellowish color.

Surprisingly, yellow watermelon was cultivated before red watermelon. Yellow watermelons were bred to have higher lycopene content once watermelon became more popular, which turned it redder over time. Originating in Africa, this yellowish kind of watermelon is said to have a somewhat sweeter flavor and a thicker rind than its red cousin.

Nutritional Benefits of Yellow Watermelon

In terms of nutritional value, yellow watermelon amounts to about 46 calories in a cup and makes for a wonderful snack. Similar to red watermelon, yellow watermelon is high in vitamins A and C, which can support the immune system and skin health. Unlike red watermelon, yellow watermelon contains more beta-carotene, which is an antioxidant that may protect against cancer and eye diseases.

With its many health benefits and low calorie count, yellow watermelon is a great choice for anyone who’s looking for a sweet, refreshing snack. This yellow fruit can also be used for desserts, such as fruit tarts or smoothies, or it can also be included as a topping on a creative salad. It can also be juiced for a refreshing drink that retains the yellow watermelon’s original flavor. Not only can yellow watermelon aid with detoxing and prevent bloating, but the high percentage of water can also keep you hydrated for the whole day.

How to Pick the Best Watermelon

Yellow watermelon is generally interchangeable with red watermelon, and I would personally choose whichever is cheaper at the grocery store. That said, for those who have not tried yellow watermelon before, I would highly recommend it.

If you’re at the grocery store looking for a nice, ripe yellow watermelon, check for melons that have a creamy yellowish spot on the rind. A ripe watermelon, yellow or red, should feel quite heavy and should also make a hollow sound if you lightly thump it. Watermelons are usually the tastiest during the summer, but that shouldn’t stop you from picking up a yellow watermelon any time of the year.

Summertime is the perfect season for sweet, crisp watermelon. There are few things sweeter than biting into watermelon wedges on the beach, in the backyard, or even on road trips. While you might know a few basic watermelon tricks, like sticking popsicle sticks in the wedge rinds or salting it to bring out the sweetness, you might not know everything about watermelon. Did you know that yellow watermelon exists? And not only does it exist, but it’s also delicious.

So what’s the difference between yellow flesh watermelon and your garden variety regular red watermelons? Traditional watermelons get the pinkish-red flesh from lycopene, a powerful antioxidant and the stuff that makes tomatoes red — and what scientists modified to create these pink pineapples. Watermelon varieties that don’t contain lycopene will often have a yellow fruit.

On the outside, yellow watermelons look just like any other watermelon, with a green rind. They can be seedless watermelons, with countless seedless varieties. With yellow watermelons, though, it’s what’s on the inside that counts.

Aside from the obvious color difference, yellow watermelons tend to be sweeter than their reddish relatives, described with notes of honey and apricot.

A happy accident lol #yellowwatermelon

The sweet taste makes it especially perfect for soaking in booze, like tequila or rum for a tasty, saucy treat. While it’s not an extremely sweet taste, it cuts through the edge of spirits nicely.

Yellow watermelons are available year-round from specialty produce suppliers — and maybe some select grocery stores — with a peak season in the summer months.

Yellow Flesh Black Diamond Watermelon, Desert King, Yellow Crimson, Yellow Doll, Buttercup and Tastigold are just a few of the varieties of yellow watermelon for sale and cultivation.

While many people think it’s the other way around, there’s a good amount of evidence indicating the yellow and white varieties of watermelons actually predate the pink and red melons we are familiar with today.

If you’re ready to give this watermelon a go, you can pick up yellow watermelon seeds online or at your local plant store. If you want to stick to traditional reddish tint watermelons, we don’t blame you, but branching out won’t hurt.

The science behind this strange looking watermelon may surprise you.
At first glance, it looks like someone has taken a lot of time to carve a strangely intricate pattern on the inside of this watermelon. In reality, what’s happened to this watermelon is a natural condition called “hollow heart.” That’s right. This piece of fruit literally looked exactly like that when it was cut open.

Reddit

“Hollow heart” develops when there is poor pollination during the growth process that creates cracks inside of the watermelon.

University of Delaware researcher Gordon Johnson explains the science behind “hollow heart” in detail:

“In the past, the cause for hollow heart was thought to be related to rapid growth of the fruit where the rind expanded faster than the internal flesh leading to separation of the three internal fruit compartments and an open area between. Excess nitrogen and over-watering along with favorable growing conditions were implicated in higher incidence of hollow heart.

There is growing evidence that hollow heart is not directly tied to nitrogen and water management but is related to pollination and weather conditions during pollination. Plant hormones are thought to be important in this effect. Several researchers have found no increase in hollow heart with increases in nitrogen; even in varieties know to have hollow heart problems. It is thought that with inadequate pollination, there is reduced release of the plant hormone that controls the development of storage tissue leading to hollow heart.”

Although the sight might be alarming when the melon is first cut open, the affected fruit is still entirely safe to eat.

University of Delaware Reddit

So next time you’re carving a watermelon for your summer picnic, don’t be afraid if you see this crazy pattern on the inside. It’s just science working its natural magic.

How To Pick A Good Watermelon

June 27, 2018

Here are six tips for How to Pick a Good Watermelon that’s ripe and sweet, gathered from lots of conversations with produce people, farmers, and personal experience. If you know how to check for things like the field spot, it makes the selection process much easier!

Picking out a watermelon at the grocery store was always a semi-anxiety plagued experience for me when I didn’t know what I was looking for.

If you pick a bad one, you’re stuck with 15-20 whopping pounds of watermelon terribleness. And then your options are to either force yourself to eat this yucky watermelon or throw it away…and both are less than desirable options.

There have been a few times where I ended up throwing it out because it tasted like a crunchy watermelon rind cucumber, and no one in my family would eat it.

My goal today is to help you pick sweet, ripe watermelons because I know how disappointing it is to get home, take your first bite of some sort of produce you buy, only to find out it isn’t good.

All the tips here are tidbits I have gathered from personal experience and lots of conversations with produce people and farmers.

How to Pick a Good Watermelon:

Tip #1: Find the Field Spot

If you don’t even read the other tips, I find this is the biggest indicator of a good watermelon.

The field spot is a creamy spot on the outside, and it’s where the watermelon was resting on the ground. The field spot should be a yellowish creamy color, like shown with my watermelon:

What’s interesting is you’ll notice that the other side of the same watermelon looks completely different:

Much prettier and more typical of what I picture when I think of a watermelon, and that’s okay. I find that the best watermelons I buy can sometimes look really gnarly on one side where it was resting on the ground, and then unblemished on the other.

The more dark yellow the field spot is, the longer it was on the vine sweetening up. If the field spot is white (or not even there), this indicates an underripe melon.

Tip #2: Pick a Dull Looking Watermelon

A shiny appearance indicates an underripe melon. This applies to honeydew melons too.

Tip #3: Knock on It with Your Knuckles

Your knuckles should bounce off the melon, and the surface should be pretty hard/firm. You will get a dull thud if the flesh is soft, which indicates it’s starting to spoil.

Tip #4: Get the Heaviest One for Its Size

This applies to pretty much all produce, but you want to pick the watermelon that is the heaviest one for its size. That means there’s more water in it.

The watermelon pictured above here in my post was a whopping 18 pounds! It was heavier than the other comparably sized melons around it.

Tip #5: Check for a Uniform Shape

Some watermelons are round, some are oval, and either is fine. But if there are irregular bumps, this indicates the melon may have gotten inconsistent amounts of sun or water.

Tip #6: Look for the Sugar Spots and Pollination Points

This tip was emailed to me many months ago by Tom, a produce manager for a major grocery chain. If you see black spots on the melon (as pictured above), this is where sugar is seeping out and indicates a sweet melon. Also, if you see dots in a line (not a scratch), these are pollination points, and the more of them the better. I’ve been looking for these every time I pick up a melon and have had great luck with it in addition to the other tips. Thank you, Tom!

Once you’ve picked out your watermelon, take a look at my quick guide for How to Cut a Watermelon:

It is SO much easier than cutting the typical triangles that include the rind, and you can either cut it into sticks or cubes:

Yellow Meated Watermelon

Light requirements: Full sun.

Planting: Space 36 to 60 inches apart. (Read the stick tag that comes with the plant for specific spacing recommendations.)

Soil requirements: Provide well-drained, nutrient-rich soil that’s high in organic matter. Work at least 3 inches of organic matter into planting beds—more is better. Soil should be at least 70ºF at planting.

Water requirements: Keep soil consistently moist until fruits are about the size of a tennis ball. After that, water only when soil is dry. Avoid overhead watering to beat foliar diseases; use soaker hoses instead. About a week before fruits are ripe, water only if leaves wilt. Withholding water at this stage concentrates sugars in fruit.

Frost-fighting plan: Even a very light frost (31 to 33ºF) can kill watermelon vines. Use frost blankets or cold frames to protect vines and prolong the harvest season. To ensure fruits ripen before frost, remove any blossoms that start to develop within 50 days of your area’s average first frost date.

Common issues: Pests to watch out for include melon aphids, along with spotted and striped cucumber beetles. Fungal diseases such as alternaria leaf spot, gummy stem blight, anthracnose, downy mildew, and powdery mildew can attack plants.

Harvesting: Harvest when rind changes from bright to dull green, and the part that touches soil shifts from greenish white or straw yellow to rich, creamy yellow. Rap on the skin and listen for a low-pitched thud; tune your ear to the incorrect sound by rapping on a few fruits that aren’t ripe. Underripe fruits resonate with a high-pitched, tinny sound. Cut melons from the vine, leaving about an inch of stem attached to prevent rotting if they’ll sit before use.

Storage: Watermelons keeps 2 to 3 weeks unrefrigerated. Place in a cool area, such as a basement, to increase holding time. After cutting, refrigerate unused portions. If you have extra melon on hand, dice or cut the flesh into balls and freeze.

Best Season for Growing Yellow Watermelons

True Lovers of Heat

Regardless of the variety you are growing, all yellow watermelons are heat-lovers that perform best when outdoor conditions are consistently warm. Depending on where you live, your season of prolonged warm temperatures might start as early as March or in late May to early June.

The more north you reside, the later you can expect to safely plant your yellow watermelon seeds or transplants. These are warm-season annuals very sensitive to frosty, cold temperatures. In fact, Florida is the only state where the year-round warm climate makes it possible to grow watermelons all year.

Prime Temperatures for Germination & Planting

Since outdoor conditions that are too cold impede the watermelon plant’s growth and seeds can fail to germinate, it’s important to plant when temperatures are at their prime.

  • The best temperatures for germination are between 70°F to 95°F (21.1°C to 35°C). Germination occurs in a couple of days, when seeds are planted in 95°F (35°C) and can take a week, when planted in 70°F (21.1°C).
  • Watermelons thrive when planted and grown with temperatures ranging between 70°F and 85°F (21.1°C and 29.4°C), but still handle temperatures of 90°F (32.2°C).

How to Get a Jump on the Season

If you live in a cooler region where the growing season is shorter, or you just want to get a head start on growing your yellow watermelon plants, there are steps you can take to get things off to a good start.

  • In late winter or early spring, cover the garden area with black plastic, being sure to secure the ends in place. This not only organically kills any unwanted vegetation, but the black plastic helps the soil retain warmth.
  • You can also mulch around the watermelon plants with black, plastic mulch, which helps retain heat in the soil.
  • Placing fabric row covers over young plants also retains warmth in the soil. However, once the plants start blooming you have to remove the covers for proper pollination of the flowers. Keeping the row covers in place can impede pollination, which reduces the watermelon crop.
  • Start seeds indoors in peat pots two to four weeks before the last frost in your area, and plant out in the garden two weeks after the last frost. Like all melons, watermelons have sensitive roots and you can plant the entire peat pot in the garden without disturbing the root system.

Expert Tip: Plant your yellow watermelon seeds ½ inch deep.

Selecting the Right Yellow Watermelon Variety

When selecting a yellow watermelon variety to grow, you’ll want to pay attention to the seed packet and how many days from planting until harvesting. If you live in an area with a shorter season, you’ll want to select a cultivar that doesn’t take as long to ripen.

However, if you live in a location with a prolonged season on warmth, you can grow any yellow watermelon variety because it will have time to ripen before cold weather arrives. Some yellow watermelon varieties, including those with yellowish outer skin and their characteristics include:

  • ‘Yellow Doll’ is a hybrid producing 3- to 7-pound, yellow-fleshed melons green striped skin. Semi-compact vines mature in 68 to 80 days.
  • ‘Yellow Alice’ is a Korean hybrid producing small, round fruits with yellow-flesh. Matures in 55 to 60 days.
  • ‘Golden Midget’ produces 3-pound fruits, with golden yellow skin and pink inner flesh. Matures in around 70 days.
  • ‘Golden Crown’ produces 5- to 7-pound, red-fleshed fruits with golden yellow skin and is disease-resistant. Matures in 78 days.
  • ‘Desert King’ produces 20- to 30-pound, yellow-fleshed fruit and takes 85 to 100 days to mature.
  • ‘Sweet Siberian’ produces 8- to 10-pound, yellow-fleshed fruit, with light green skin. Matures in around 80 to 85 days.

Expert Tip: Yellow watermelon varieties producing smaller fruits are suitable for growing up a trellis. Just make sure the trellis is sturdy enough to hold the developing fruits. You can support the melons with pantyhose, placing them around the watermelons and creating a sling while they are still small.

What Is a Yellow Watermelon?

When the dog days of summer set in and you are facing an afternoon filled with haze, humidity, and languid breezes (if there is even a breeze at all), the one thing that will coax you out onto the back porch is the promise of a sweet, juicy, and crisp watermelon. There are few things more refreshing than biting into a watermelon wedge, letting the juice trickle down your arms, and seeing how far you can spit the seeds. While the most popular way to eat a watermelon is to just dive in, they are also delicious blended into cocktails, paired with tomatoes in salads, and even turned into a creamy, frozen pie. You may be lucky enough to grow your own watermelons in your garden or you might visit a farmers’ market for your favorite varieties, such as the Sugar Baby or Crimson Sweet. The traditional varieties all have red or pink flesh, but have you run across the yellow watermelon? With over 1,200 varieties of watermelon on the market today, from seedless to pink to melons with a black rind, you shouldn’t be surprised to find a yellow fleshed melon. Read on and see what makes it so different.

What Makes Them Yellow

Some fruits and vegetables, such as cherries, blueberries, grapes, and purple sweet potatoes, contain anthocyanins, a flavonoid which provides their rich color. Traditional watermelons get their pinkish to red hues from lycopene, the same powerful antioxidant that makes tomatoes red. Obviously, watermelon varieties that do not contain lycopene will often have a yellow flesh.

They Look the Same on the Outside

You can’t judge a book by its cover, and you can’t judge a watermelon by its rind, because a yellow watermelon has a green rind, just like every other watermelon. So, unless the produce is labeled correctly at the market, you will have to cut into a melon to determine if it is yellow or red. There are as many varieties of yellow watermelons as there are red ones, both with seeds and seedless.

Use a Yellow Watermelon the Same Way

Aside from the obvious color difference, the fruit of the yellow watermelon is sweeter than its red-fleshed counterpart, described as having notes of honey and apricot. Yellow watermelon fruit is now widely available and can be used in the same recipes as you would use a red watermelon, you may want to even mix red and yellow melons in a recipe for added visual appeal.

How do I know when a watermelon on the vine is ripe

This post is primarily for those who are wondering if their homegrown watermelon is ripe and ready to pick, but most of the same tips apply for those rooting through the produce bins at the supermarket or scouting out the farmers market. Watermelons are a little sneakier than muskmelons, which slip right off the vine (i.e. come loose on their own) when ripe. Uncut watermelons are also less fragrant than muskmelons, because they don’t have that open end where the vine was formerly attached. You will never find me sniffing watermelons in the grocery store, but you may find me sniffing cantaloupes. (I do my own stunts. )

4 Clues to Tell if Your Watermelon is Ripe

Back in my late teens and early 20’s, my jobs at the family catering business included picking out the watermelons and carving the watermelon boats for parties. I was known as the resident watermelon expert, almost guaranteed to be able to pick out the perfect melon, if there was a perfect melon to be found.

Ripe Melon Tip #1 – Make Sure Your Watermelon is at Full Growth

If you’re watching the patch, you can tell when a particular melon is large, well filled out, and hasn’t changed significantly in size for some time. For first time growers, you can check the expected size on the package and weigh them if you want, but the best way to tell is to observe the growth habits of the melon.

Ripe Melon Tip #2 – Check the Little Curling Tendril Located Where the Watermelon Stem Joins the Main Vine

Right where the stem to your melon joins the main vine, there should be a little curling tendril or curly cue of vine. If this little tendril is brown and dried, odds are your melon is as ripe as it’s going to get. If the tendril is still green and springy, the melon is still growing. Sometimes all your vines may start dying back before you’ve harvested, not just a tendril. Ready or not, this is as ripe as your watermelons are going to get. Unlike some fruits, watermelons do not ripen further once they are off the vine.

Ripe Melon Tip #3 – Look at the Under Side of the Melon

The under side of the watermelon where it hits the ground should be buttery to dark yellow. If it’s as pasty white as a bald guy’s head in the middle of a Wisconsin winter, it probably hasn’t reach peak ripeness. This is a good thing to look for on purchased melons, too. Different growing conditions and different types of melons will produce a range of colors (inside and out). Much of our summer was cool and dry, less than optimal melon weather. When rain finally came, it came as a deluge, which sent the slug population skyrocketing. When I flipped over our first ripe melon, I was frustrated to find slug damage underneath. Thankfully the rind was thick and the damage didn’t go all the way though. You can see this one only has a light yellow tint. Warmer weather usually yields a darker yellow bottom.

Ripe Melon Tip #4 – Listen to the Sound

This is a classic, and the internet is filled with descriptions of what the sound should be when you thump a watermelon. Most say “flat” or “dull”. I think that’s a poor description. For my part, “flat and dull” is the sound you get when you rap on something like a giant zucchini – or an underripe watermelon. A ripe melon should have a nice, deep sound, more like a drum or knocking on a door. I did a quick video (below). My Powershot D10 doesn’t quite do it justice, but you get the general idea.

Here’s the end result. Given our uncooperative gardening season, even with the landscape fabric and other tactics to create a warmer microclimate for the melons, they didn’t get as deep red out far to the rind as I would prefer, but the flavor was still very good and they were very juicy because of recent rains. You can tell the melon is mature by the dark seeds and the cavities around the seeds.

Quick Tip for Melon Storage – Don’t stick your uncut melons in the refrigerator!

Before our melons were ready, I picked one up at the grocery store that I really shouldn’t have bought. It was during our brief hot spell this summer, and the melons had obviously been stored too cold because they were chilled and sweating in the bins. Sure enough, I got it home and the flavor was bland and the texture was mushy. Melons like it warm! Room temperature storage also makes them more nutritious.
