The best time to pick a Jubilee watermelon is when it reaches full maturity, usually around 80 to 90 days after planting.
That’s when the sugars are at their peak and the flesh is deep red, juicy, and sweet.
If you pick a Jubilee watermelon too early, the flesh will be pale, bland, and sometimes even crunchy in a bad way.
If you wait too long, it can turn mealy and lose that refreshing crispness.
So if you’ve been asking when to pick a Jubilee watermelon, the short answer is: when it’s fully ripe on the vine, and there are several clear signs to look for.
In this post, we’ll walk through exactly when to pick a Jubilee watermelon, the signs that tell you it’s ready, and a few tricks to make sure you never harvest too soon or too late.
Let’s dive in.
When to Pick a Jubilee Watermelon: The Key Signs
Knowing when to pick a Jubilee watermelon comes down to reading a few reliable signals.
Jubilee watermelons are a large, oblong variety known for their light green skin with dark green stripes.
They typically mature later than many other watermelons, so patience is key.
Here are the signs that tell you when to pick a Jubilee watermelon:
1. The Tendril Nearest the Fruit Turns Brown
One of the most reliable signs of when to pick a Jubilee watermelon is the tendril.
Look for the small, curly tendril growing on the vine right next to where the watermelon attaches.
When that tendril dries up and turns brown, the watermelon is ripe and ready.
If it’s still green and pliable, the Jubilee watermelon needs more time on the vine.
2. The Ground Spot Turns Creamy Yellow
Flip your Jubilee watermelon over and check the spot where it rested on the ground.
A ripe Jubilee watermelon will have a creamy yellow or pale orange spot there.
If that spot is still white or greenish, it’s a clear sign the fruit isn’t ready yet.
This ground spot is one of the easiest ways to tell when to pick a Jubilee watermelon without cutting it open.
3. The Skin Loses Its Shine
A mature Jubilee watermelon has a dull, slightly matte surface instead of a glossy one.
When the skin looks shiny and reflective, the fruit is still developing.
Once that shine fades and the rind feels a bit tougher, it’s a good indicator that the time to pick a Jubilee watermelon has arrived.
4. The Thump Test Gives a Deep, Hollow Sound
Give your Jubilee watermelon a firm thump with your knuckles.
A ripe Jubilee watermelon produces a deep, hollow sound, almost like a drum.
A dull thud usually means it’s underripe, while a sharp ping can mean it’s overripe.
This old-school trick still works wonders when you’re trying to figure out when to pick a Jubilee watermelon.
How to Pick a Jubilee Watermelon at the Right Stage
Even if you know the signs, timing your harvest can still feel tricky.
Here’s how to pick a Jubilee watermelon with confidence:
1. Track the Days From Planting
Jubilee watermelons usually take 80 to 90 days to reach full maturity.
Mark your calendar from the day you planted or transplanted them.
When you’re close to that window, start checking the physical signs daily.
This gives you a solid baseline for when to pick a Jubilee watermelon.
2. Check in the Morning
The best time of day to pick a Jubilee watermelon is in the morning before the heat sets in.
That’s when the fruit is cool and hydrated, which means it’ll be crisp and refreshing.
Avoid picking during the hottest part of the afternoon, as the melon can be warm and less flavorful.
3. Use a Sharp Knife and Leave a Stem
When you finally pick a Jubilee watermelon, use a sharp, clean knife or pruners.
Cut the stem about one to two inches from the fruit instead of yanking it off the vine.
This small stem helps the watermelon store longer and keeps it from spoiling quickly.
Common Mistakes When Picking a Jubilee Watermelon
A lot of gardeners struggle with when to pick a Jubilee watermelon because of a few common mistakes.
Here’s what to avoid:
1. Relying Only on Size
Big doesn’t always mean ripe.
Jubilee watermelons can vary in size, and some will keep growing even after they’ve matured.
Always combine size with the tendril, ground spot, and thump test before you pick a Jubilee watermelon.
2. Picking Too Early Out of Excitement
It’s tempting to grab that first big Jubilee watermelon as soon as it looks good.
But picking too early leads to disappointing flavor and wasted effort.
Waiting just a few extra days can make a huge difference in sweetness when you pick a Jubilee watermelon.
3. Ignoring the Weather
Heavy rain right before harvest can water down the flavor of a Jubilee watermelon.
If a big storm is coming and your melon is already ripe, it’s often better to pick a Jubilee watermelon before the rain hits.
That way, you preserve the sugars instead of letting them get diluted.
So, When to Pick a Jubilee Watermelon?
The best time to pick a Jubilee watermelon is when the tendril near the fruit turns brown, the ground spot is creamy yellow, the skin loses its shine, and a thump gives a deep hollow sound.
You should aim to pick a Jubilee watermelon around 80 to 90 days after planting, ideally in the cool morning hours.
And while it’s tempting to harvest early, patience is what gives you that sweet, juicy flesh Jubilee watermelons are known for.
Hope this post has helped you understand exactly when to pick a Jubilee watermelon so you can enjoy a perfect harvest every single time.
