History and Origin

Let’s take a little trip back to 1979, a year that marked a sweet revolution in the world of watermelons. That’s when the Crimson Sweet first made its grand entrance, thanks to the hard work of the USDA. They were on a mission to create a watermelon that wasn’t just deliciously sweet but also tough against the common foes of melons – diseases like fusarium wilt and anthracnose.

The result? A watermelon that quickly became a hit in gardens and farms far and wide. The Crimson Sweet wasn’t just any melon. It was a standout with its deep green stripes and vibrant red, juicy interior, packed with that perfect sweetness we all crave on a hot summer day. But its appeal wasn’t just skin deep. This melon was robust, offering peace of mind to those growing it with its resistance to pesky diseases.

Description and Characteristics

The Crimson Sweet Watermelon is a large, round melon that averages about 20-25 pounds and measures approximately 10 to 12 inches in diameter.

Flavor Profile

The Crimson Sweet Watermelon is characterized by its sweet and juicy taste. Its flesh is a deep red, almost crimson color that can be seen from the outside of the melon. This variety of watermelon has a crisp texture, and when ripe, it will have an intense sweetness that is incomparable to any other type. It has a mild, slightly tart flavor, making it the perfect ingredient for various dishes.

Growing Conditions

Crimson Sweet watermelon can be grown in full sun, although it requires well-drained soil with a pH range of 6.0 to 6.5. The plant needs at least an inch of water every week during the growing season, although rainfall frequently meets this amount. The soil can retain moisture by receiving organic matter by adding compost or old manure. Plan for the vines to occupy a sizable portion of your garden because they grow swiftly and require a lot of room to spread out.

Nutritional Benefits

Crimson sweet watermelon is a nutritious fruit that offers many health benefits. It’s low in calories and rich in vitamins, minerals, and antioxidants. A cup of cubed watermelon contains only 48 calories while providing important nutrients like vitamin C, magnesium, potassium, copper, and manganese.

Planting Instructions

Planting Crimson Sweet Watermelon is a fun garden project that brings sweet rewards. Here’s how to do it, step by step.

  • Find the Perfect Spot: Watermelons love the sun, so choose a sunny part of your garden. They need about 6 to 8 hours of sunlight daily to thrive.
  • Soil Matters: These melons prefer well-drained, fertile soil. Add some compost or manure to enrich your soil before planting. A pH between 6 and 6.8 is just right.
  • Sowing Seeds: Wait until the threat of frost is gone and the soil is warm. Plant seeds about an inch deep in the ground. Space them out about 2 feet apart in rows, with rows about 4 to 6 feet apart. This gives them room to spread.
  • Water Wisely: Keep the soil moist, especially during the early stages of growth and when the fruits start to form. But be careful not to overwater.
  • Transplanting Seedlings: If you started your seeds indoors, move them outside after the last frost. Make sure to harden them off first to get them used to outdoor conditions.

With a little patience and care, you’ll see your Crimson Sweet Watermelons start to grow, promising delicious fruits for later in the summer.

Growth Stages and Days to Maturity

Watching a Crimson Sweet Watermelon grow is like following a slow, rewarding journey. Let’s break it down into stages, so you know what to expect from seed to harvest.

  • Germination: This is where it all begins. After planting your seeds, they’ll need about 7-10 days to sprout, given the soil is warm enough. You’ll see little green shoots pushing through the soil, a sure sign your watermelon journey is underway.
  • Seedling Stage: Those shoots will grow into small plants with a couple of true leaves. This stage is crucial for establishing a strong foundation for future growth. It lasts about 3-4 weeks.
  • Vining Stage: Next comes the fun part. Your plants will start to vine, spreading out across the ground. This is when they’re getting ready to flower and eventually bear fruit. This stage can last a good while, as the vines get bigger and start to flower.
  • Flowering and Fruit Set: After about 35-45 days from planting, you’ll notice flowers. These will turn into tiny watermelons before you know it.
  • Fruit Growth to Maturity: Now, patience is key. It takes about 80-85 days from planting for Crimson Sweet Watermelons to reach maturity. You’ll know they’re ready when they sound hollow when tapped and have a creamy yellow spot where they rest on the ground.

From tiny seeds to juicy watermelons, each stage brings its own excitement and challenges. Just give them love, water, and sunshine, and they’ll do the rest.

Care and Maintenance

Caring for Crimson Sweet Watermelon plants is pretty straightforward, but there are a few tips to keep in mind to help them thrive.

Watering: These plants love water, especially when they’re young and when the fruits are growing. Aim to keep the soil consistently moist but not soggy. A deep watering once a week should do the trick, but feel free to adjust based on the weather. Hotter days might call for a bit more water.

Fertilizing: A little food goes a long way. Start with a balanced fertilizer when you plant them, and then give them a boost with a high-potassium fertilizer once they start flowering and setting fruit. This helps develop those big, juicy watermelons we all love.

Pest Management: Keep an eye out for common pests like aphids and cucumber beetles. They’re not just annoying; they can harm your plants. A good spray of water can knock aphids off, and floating row covers can help keep beetles away. Also, be on the lookout for diseases like powdery mildew. Keeping the leaves dry and ensuring good air circulation can help prevent it.

When to Pick and Harvest

Picking the perfect Crimson Sweet Watermelon is all about timing. You want that sweet, juicy taste to be just right. So, how do you know when it’s time to harvest? Here are a few signs to look out for.

First, check the color on the bottom. When a watermelon is ripe, the spot where it rests on the ground turns from white to a creamy yellow. It’s like the melon’s way of saying, “I’m ready!”

Next, give it a knock. A ripe Crimson Sweet will have a deep, hollow sound, kind of like thumping a drum. If it sounds more like a thud, it might need a bit more time.

Also, take a look at the tendril closest to the fruit. When it’s brown and dried up, that’s a good indicator your watermelon is ripe. If it’s still green, your melon is probably not quite ready yet.

Lastly, the skin of the watermelon becomes tougher when it’s ripe, resisting a bit when you try to scratch it.

Spacing and Yield Per Plant

When it comes to growing Crimson Sweet Watermelons, giving them enough room to sprawl out is key. These plants are not shy; they like their space. For healthy growth, you’ll want to plant them about 3 to 4 feet apart in rows. And those rows? Keep them a good 6 to 8 feet apart. This might seem like a lot, but trust me, those vines will thank you by spreading out and soaking up the sun, leading to more and bigger watermelons.

Now, let’s talk about what you can expect to harvest from each plant. On average, a well-cared-for Crimson Sweet Watermelon plant can yield about 2 to 3 large melons. These aren’t just any melons, though. We’re talking about watermelons that can weigh anywhere from 20 to 25 pounds each when they’re ripe and ready.

So, with the right spacing and a little TLC, each of your Crimson Sweet plants can become a mini watermelon factory. Just imagine the delicious, juicy watermelons you’ll have, perfect for summer picnics or a refreshing snack. Give them room to grow, and they’ll reward you generously.

Where are Crimson Sweet Watermelon Grown in the US?

Crimson Sweet Watermelon is typically grown in the warmer climates of the United States, such as California, Arizona, and Florida. It is also commonly grown in parts of Mexico and South America. The melons are usually harvested by hand when they reach full size and maturity.

During harvest time, workers will go through fields, pick out the ripe watermelons, and place them into baskets. Once collected, the melons are washed and shipped to stores or markets for sale. Farmers may sometimes use a mechanical harvesting machine that can pick up multiple watermelons at once. This method is faster, but it can also bruise the skin of the melon, resulting in less-than-perfect fruit.

Where can the Best Quality Crimson Sweet Watermelon be found?

The best quality Crimson Sweet Watermelon can be found at farmer’s markets, grocery stores, and specialty produce shops. It is important to look for melons free from bruises or cuts in the skin as these defects could compromise When purchasing, make sure to pick a melon with a smooth rind that has no cracks, cuts, spots, or discoloration on the surface. Additionally, look for melons that feel heavy for their size and have a bright yellow spot where they rest on the ground. 

Comparison with Other Varieties

When you’re picking out watermelon seeds, you might find yourself wondering about the differences between varieties like Crimson Sweet and Sugar Baby. Both are fantastic, but they’ve got their own unique perks.

Crimson Sweet is the big guy on the block. These watermelons are known for their size, often weighing in at 20 to 25 pounds. They’ve got beautiful dark green stripes and a sweet, juicy red flesh that’s hard to beat. They need a bit of room to grow, thanks to their sprawling vines, and they thrive in warm, sunny spots with well-drained soil.

On the flip side, Sugar Baby is the more compact cousin. These melons are smaller, usually weighing around 8 to 10 pounds, making them a great choice if you’re tight on space. They have a dark green, almost black rind, and their flesh is just as sweet and delicious as the Crimson Sweet. Sugar Babies can fit into smaller gardens or even large containers, making them versatile for different growing conditions.

Both varieties bring the sweet, refreshing taste we love in watermelons, but your choice might come down to how much space you have and whether you’re up for wrestling with a 25-pounder or prefer something a bit more manageable.
