Summer’s sweet treat: Watermelon

Watermelon is one of the most beloved summer treats in the U.S. Americans eat more of it than any other melon — more than 14 pounds per person per year! In fact, we eat so much watermelon that domestic production can’t keep up with demand. The U.S. imported about 1.7 billion pounds of watermelon in 2019, which is about one-third of all the watermelon consumed here. 

Yes, it’s safe to say that we love watermelon. But because it typically grows in very warm climates, you may not think of it as a Washington crop. In this blog, we’ll share everything you need to know about Washington-grown watermelon and why it might be a good addition to your community or backyard garden.

Watermelon: A sweet treat packed with good stuff

There’s some debate as to whether watermelon is a fruit or a vegetable. The National Watermelon Promotion Board says that it could be considered either — or both! But regardless of whether we call them a fruit or a vegetable, one thing is undeniable: they’re really good for you. In fact, watermelon is a good source of Vitamin A, which contributes to eye and skin health. It also has Vitamin B6 and Vitamin C, both of which help strengthen your immune system. Watermelon is also a good source of potassium. 

But beyond having plenty of vitamins, watermelon can also help you hydrate. In fact, watermelon are made up of over 90% water. This is probably one reason why it’s such a popular summer snack!

Washington-grown watermelons

While Washington is not one of the top producers of watermelons in the U.S., they do grow well here. In fact, two separate trials conducted by Washington State University’s Vegetable and Research Extension showed that over 130 varieties of watermelon can be grown in our state. And while you might assume the trials were conducted in hot, sunny Eastern Washington, they actually took place in Mt. Vernon and Vancouver.

Even though WSU's watermelon trials took place on the west side of the state, growing them there requires some extra special care  — and quite a bit of luck. Once your watermelons begin to grow, it’s a good idea to get them off the ground to keep the fruit from rotting. Even though they need a lot of water, watermelon don’t want to wallow in it. Once that’s done, you’ll need to hope for a string of hot, sunny days. Without them, your watermelons will probably not ripen. 

It’s a different story in central and south-eastern Washington, though, where summer holds on well into September. In this part of the state, gardeners and farmers will need to make sure their watermelons are getting plenty of water, but the sunshine probably won’t be in short supply. It’s thanks to this part of the state that Washington is able to produce some watermelon commercially. In fact, according to Oregon State University, Washington and Oregon cultivate nearly 2,000 acres of watermelon each year.

The end (of watermelon season) is near
