How To Grow Watermelons In Mississippi

Growing watermelons in Mississippi is absolutely doable and actually one of the most rewarding things you can plant in your backyard garden here.

If you’ve ever wondered how to grow watermelons in Mississippi, you’re in the right place because this state is practically built for it.
 
In this post, we’ll walk through how to grow watermelons in Mississippi from seed to harvest, including the best planting times, soil prep, and tips to keep your melons sweet and juicy.
 
Let’s dig in.
 

How to Grow Watermelons in Mississippi

Learning how to grow watermelons in Mississippi starts with understanding the state’s climate.
 
Mississippi sits in USDA hardiness zones 7b through 9a, which means mild winters and long, hot summers.
 
That heat is exactly what watermelons crave, since they need soil temperatures of at least 70°F to germinate and thrive.
 
To grow watermelons in Mississippi successfully, you want to plant after the last frost date, usually between late March and mid-May depending on your zone.
 
Here’s how to grow watermelons in Mississippi step by step:
 

1. Pick the Right Variety for Mississippi

When growing watermelons in Mississippi, variety selection matters more than you’d think.
 
Look for heat-tolerant and disease-resistant types like Crimson Sweet, Jubilee, Charleston Gray, or Sugar Baby.
 
These varieties handle Mississippi’s humidity and common issues like anthracnose and fusarium wilt better than most.
 
If you’re growing watermelons in Mississippi for the first time, smaller icebox types like Sugar Baby are easier to manage.
 

2. Choose a Sunny Spot With Good Drainage

Watermelons need at least 8 to 10 hours of full sun daily.
 
Since Mississippi gets plenty of rain, planting on raised mounds or hills keeps the roots from sitting in soggy soil.
 
Good drainage is critical because watermelons rot fast in waterlogged ground.
 
Pick a spot where water doesn’t pool after a summer storm.
 

3. Prepare the Soil

Watermelons love loose, sandy loam with a pH between 6.0 and 6.8.
 
Before planting, mix in compost or aged manure to give the soil nutrients and improve drainage.
 
You can also add a balanced fertilizer like 10-10-10 at planting time.
 
Since Mississippi soil can be heavy clay in many areas, amending it well is a big part of how to grow watermelons in Mississippi successfully.
 

4. Plant Seeds or Transplants Correctly

Plant seeds about 1 inch deep in hills spaced 4 to 6 feet apart.
 
If you’re using transplants, wait until soil temps hit 70°F so the roots take off quickly.
 
Many Mississippi gardeners start seeds indoors 3 to 4 weeks before the last frost.
 
When learning how to grow watermelons in Mississippi, timing your planting around the frost date is one of the most important steps.
 

Care Tips for Growing Watermelons in Mississippi

Once your plants are in the ground, keeping them healthy is the real work.
 
Here’s how to grow watermelons in Mississippi through the whole season:
 

1. Water Deeply but Not Too Often

Watermelons need about 1 to 2 inches of water per week.
 
In Mississippi’s humid summers, you may not need to water as much, but during dry spells, give them a deep soak once or twice a week.
 
Avoid overhead watering since wet leaves invite disease.
 

2. Watch for Pests and Diseases

Mississippi’s humidity brings pests like aphids, cucumber beetles, and squash bugs.
 
Common diseases include powdery mildew and downy mildew.
 
Use row covers early on, and apply neem oil or fungicide when needed.
 
Growing watermelons in Mississippi means staying on top of these issues before they spread.
 

3. Pollination Matters

Watermelons need bees to pollinate their flowers.
 
If you notice few bees, you can hand-pollinate by transferring pollen from male to female flowers.
 
Good pollination is what leads to full, well-shaped melons.
 

4. Fertilize Wisely

After the vines start running, side-dress with nitrogen fertilizer.
 
Once fruit sets, switch to a fertilizer higher in phosphorus and potassium.
 
Too much nitrogen late in the season gives you big vines and small melons.
 

When to Harvest Watermelons in Mississippi

Harvest time usually arrives 80 to 100 days after planting, depending on the variety.
 
In Mississippi, that’s typically July through August.
 
Look for a dried tendril near the stem, a dull skin color, and that hollow thump sound.
 
The underside should turn from white to creamy yellow.
