You can grow cantaloupe and watermelon in a garden bed, a raised bed, or even large containers.
These two melons share similar growing requirements, so you can plant them side by side.
You can grow cantaloupe and watermelon successfully by giving them rich soil, consistent watering, and lots of room to sprawl.
In this post, we’ll walk through how to grow cantaloupe and watermelon from seed to harvest.
Let’s dig in.
How to Grow Cantaloupe and Watermelon: The Basics
When you grow cantaloupe and watermelon, the fundamentals are almost identical.
Both need full sun, warm soil, and a long growing season.
Here’s what to keep in mind if you want to grow cantaloupe and watermelon the right way.
1. Choose the Right Spot
To grow cantaloupe and watermelon, pick a spot that gets at least 6 to 8 hours of direct sunlight daily.
Melons love heat, so the sunnier the better.
Make sure the area has good drainage because soggy roots will kill your plants fast.
When you grow cantaloupe and watermelon, a south-facing spot is ideal.
2. Prepare the Soil
If you want to grow cantaloupe and watermelon that taste sweet, start with rich soil.
Both melons prefer loose, well-draining soil with a pH between 6.0 and 6.8.
Mix in plenty of compost or aged manure before planting.
You can grow cantaloupe and watermelon in sandy loam or even clay soil, as long as you amend it well.
Raised beds work great if your native soil is heavy or poor.
3. Plant at the Right Time
You should only grow cantaloupe and watermelon once the soil has warmed to at least 65°F.
Cold soil will stunt or rot the seeds.
In most regions, that means planting two to three weeks after the last frost date.
If you want to grow cantaloupe and watermelon earlier, start seeds indoors three to four weeks before transplanting.
Just be careful not to disturb the roots when you move them outside.
4. Give Them Space
When you grow cantaloupe and watermelon, space is non-negotiable.
These vines sprawl and can take over a garden if you let them.
Watermelon vines need about 6 to 8 feet between plants, while cantaloupe needs 4 to 6 feet.
If you’re short on space, you can grow cantaloupe and watermelon vertically on a sturdy trellis.
Just support the heavy fruit with slings made from old cloth or pantyhose.
5. Water Wisely
To grow cantaloupe and watermelon that stay healthy, water deeply but infrequently.
Melons need about 1 to 2 inches of water per week.
Water at the base of the plant to keep the leaves dry and prevent mildew.
When you grow cantaloupe and watermelon, drip irrigation is your best friend.
Reduce watering as the fruit ripens to boost sweetness.
How to Grow Cantaloupe and Watermelon: Care Tips
Once your plants are up and running, a little care goes a long way.
If you want to grow cantaloupe and watermelon that produce a big harvest, follow these tips.
1. Fertilize at the Right Stages
When you grow cantaloupe and watermelon, feed them lightly at first.
Use a balanced fertilizer when vines start running.
Switch to a low-nitrogen blend once flowers appear.
Too much nitrogen gives you leaves instead of fruit.
2. Watch for Pests and Diseases
To grow cantaloupe and watermelon without losses, keep an eye out for aphids, squash bugs, and cucumber beetles.
Powdery mildew is the most common disease.
Plant resistant varieties and space plants well for airflow.
You can grow cantaloupe and watermelon organically by using neem oil and row covers early in the season.
3. Pollinate if Needed
When you grow cantaloupe and watermelon, bees usually handle pollination.
But if you notice few bees, you can hand-pollinate.
Pick a male flower, remove the petals, and dab it onto a female flower.
Do this in the morning for the best results.
Harvesting Cantaloupe and Watermelon
Knowing when to pick is half the battle when you grow cantaloupe and watermelon.
Here’s how to tell they’re ready.
1. Cantaloupe
Cantaloupe is ripe when the skin turns tan and the netting gets thick.
The fruit should slip easily off the vine with a gentle tug.
It should also smell sweet at the blossom end.
If you grow cantaloupe and watermelon together, mark your calendar so you don’t miss the window.
2. Watermelon
Watermelon is ready when the tendril closest to the fruit turns brown and dry.
The underside should be creamy yellow, not white or green.
Thump it and listen for a deep, hollow sound.
When you grow cantaloupe and watermelon, taste-testing is the final judge.
So, How Do You Grow Cantaloupe and Watermelon?
You grow cantaloupe and watermelon by giving them sun, space, and steady care.
Both melons reward you with sweet, juicy fruit when you plant them in warm soil and water them wisely.
Whether you grow cantaloupe and watermelon in a backyard patch or a container on your patio, the process is the same.
Pick a sunny spot, feed the soil, and let those vines run.
Before you know it, you’ll be slicing into homegrown melons that beat anything from the store.
Happy growing.
