Do Black Diamond Watermelons Have Seeds

Black Diamond watermelons do have seeds, and those seeds are one of the things that make this old-time favorite so special.
 
If you’ve ever wondered, “do Black Diamond watermelons have seeds,” you’re not alone, because plenty of gardeners ask the same thing before planting them.
 
The short answer is yes, Black Diamond watermelons are a seeded variety, not a seedless one.
 
They produce those classic black (or dark brown) seeds you’ll find scattered throughout the sweet red flesh.
 
In this post, we’ll look at whether Black Diamond watermelons have seeds, why they have seeds, and what that means for growing and eating them.
 
Let’s dig in.
 

Do Black Diamond Watermelons Have Seeds?

Yes, Black Diamond watermelons have seeds, and they always will because they’re an heirloom variety that reproduces naturally through seed.
 
That’s a big part of their charm and also the reason so many gardeners keep coming back to them year after year.
 

1. They’re a Seeded Heirloom Variety

Black Diamond watermelons are an heirloom variety, which means they’ve been passed down for generations without any genetic tweaking to remove the seeds.
 
Heirloom watermelons like Black Diamond have seeds because that’s how they’ve always grown and reproduced.
 
So when you ask, “do Black Diamond watermelons have seeds,” the answer is baked right into their history.
 
Seedless watermelons, on the other hand, are a modern hybrid creation that requires special growing conditions.
 
Black Diamond watermelons don’t fall into that category at all.
 

2. The Seeds Are Large and Black

One of the most recognizable traits of Black Diamond watermelons is their seed color and size.
 
The seeds inside a Black Diamond watermelon are typically large, dark black or dark brown, and easy to spot.
 
That’s actually where the name “Black Diamond” partly comes from, since the seeds look like little black gems.
 
So when you slice one open, you’ll see plenty of seeds right there in the flesh.
 

3. Seeded Watermelons Are the Natural Norm

It’s worth remembering that seeded watermelons are the natural norm for the species.
 
Watermelons have been growing with seeds for thousands of years, and Black Diamond watermelons carry on that tradition.
 
When you ask if Black Diamond watermelons have seeds, you’re really asking if they’re a traditional watermelon.
 
And the answer is a big, juicy yes.
 

Why Black Diamond Watermelons Have Seeds

Black Diamond watermelons have seeds because they reproduce sexually, just like most fruiting plants.
 
Here’s what’s going on under the rind.
 

1. Pollination Creates the Seeds

When bees and other pollinators move pollen from the male flowers to the female flowers, fertilization happens.
 
That fertilization is what produces seeds inside the watermelon.
 
So if you want Black Diamond watermelons to have seeds (which you do, if you’re saving them for next year), you need good pollination.
 

2. Seeds Are How Heirlooms Survive

Heirloom varieties like Black Diamond depend on seeds to keep going.
 
You can’t grow a true Black Diamond watermelon from a cutting or clone, you grow it from seed.
 
That’s why the seeds inside are so valuable to gardeners who want to keep the variety alive.
 
When Black Diamond watermelons have seeds, they’re basically handing you the tools to grow them again.
 

3. Seedless Watermelons Need Special Setup

To grow a seedless watermelon, you need to plant a special hybrid and grow it near a pollinator variety.
 
Black Diamond watermelons don’t require any of that fuss.
 
They have seeds naturally, without any extra steps.
 
That makes them simpler and more reliable for home gardeners.
 

Growing Black Diamond Watermelons and What to Expect

If you decide to grow Black Diamond watermelons, here’s what you should know about the seeds.
 

1. You Can Save the Seeds

Because Black Diamond watermelons have seeds, you can save them and plant them next season.
 
Just rinse the seeds, let them dry completely, and store them in a cool, dry place.
 
Since they’re an heirloom, the seeds will grow true to type.
 

2. Seeds Don’t Affect the Flavor

Some people worry that seeds make a watermelon less enjoyable, but that’s not true.
 
Black Diamond watermelons have seeds, and those seeds sit right in one of the sweetest, most flavorful watermelons you can grow.
 
You just spit them out or pick them out as you eat.
 

3. Expect a Big, Heavy Melon

Black Diamond watermelons are known for growing large, often weighing 30 to 50 pounds or more.
 
With a melon that big, it’s no surprise that Black Diamond watermelons have seeds, since they need a healthy seed set to reach that size.
 
Give them plenty of sun, water, and space, and you’ll be rewarded with a monster melon full of seeds.
 
 

So, Do Black Diamond Watermelons Have Seeds?

Black Diamond watermelons do have seeds, and those seeds are a natural, expected part of the fruit.
 
They’re an heirloom variety, so they reproduce through seed rather than being engineered to be seedless.
 
If you were asking whether Black Diamond watermelons have seeds, now you know the answer is a clear yes.
 
So go ahead and plant them, save the seeds, and enjoy one of the sweetest, most old-fashioned watermelons around.
