How to Grow Cantaloupe: 9 Tips for Growing Cantaloupe

Cantaloupe thrives in warm weather and needs a long growing season; great news for desert dwellers. Learn how to grow cantaloupe, and add this tasty fruit to your garden and table.

Once cantaloupe is picked, it continues to ripen but does not get any sweeter. When you grow your own cantaloupe, you can pick it at the peak of sweetness. It is so good!

9 Tips for How to Grow Cantaloupe

How to Grow Cantaloupe: 9 Tips for Growing Cantaloupe

1. Choose the best location

Cantaloupe prefers a sunny location with well-draining soil that is rich in organic matter. Amend the soil with compost and a balanced organic fertilizer prior to planting.

2. Choose a cantaloupe type suited to your needs

3. Plant cantaloupe at the correct time

Cantaloupe prefers warm weather, so don’t plant it before temperatures have warmed in the spring. Cantaloupe does best when direct sown. Sow seeds outside about 2 weeks after the last frost date when soil temperatures are about 65℉. In the low desert of Arizona, the best time to plant cantaloupe is from February 15 through July

In cooler zones, start seeds indoors about 3 weeks before the last frost date, and transplant outside when the soil is at least 65℉ and nighttime temperatures are above 50℉. Be careful not to disturb roots when planting to avoid transplant shock.

4. Reduce chances for pests and disease

  • Rotate where you plant cantaloupe and members of the cucumber family (Cucurbitaceae), such as other melons, squash, or pumpkins.
  • Once fruits have formed, raise them up off the ground with melon cradles or pots; this increases air circulation and helps with rot and insects. 
  • Grow cantaloupe vertically; they love to climb. Use a melon hammock to support the hanging fruit if desired, but it often isn’t necessary. 
  • If powdery mildew is a problem, consider growing Ambrosia or other disease-resistant varieties. 
  • Inspect leaf undersides daily for aphids and other pests. Consider spraying with water or treating with insecticidal soap if problem persists. Read this post for more ideas for pest control. 

5. Give cantaloupe plenty of room to grow

  • Thin seedlings and keep only the strongest seedling in each group. 
  • Space plants 24-36 inches apart if left to sprawl on the ground. 
  • Space plants about 12 inches apart if growing up a trellis
  • If using square foot gardening methods, allow 2-3 square feet for each plant. 

6. Care for cantaloupe correctly throughout the growing season

  • Mulch cantaloupe plants to help retain moisture, regulate temperature, control weeds, and keep fruit clean.
  • Water in the morning and avoid getting water on leaves, which can encourage disease. 
  • Fertilize when vines begin growing. 
  • Be on the lookout for bees. Male flowers will appear first, followed by female flowers. If female fruit withers and dies, consider hand-pollinating future blooms.

7. Learn how to grow cantaloupe that is sweet and full of flavor

  • Don’t overwater while fruit is growing. Too much water (or rain) produces bland-tasting fruit.
  • Consider giving vines and fruit an extra magnesium boost with an epsom salt foliar spray. Use one tablespoon epsom salt in one gallon of water. Spray when leaves begin to vine and again when fruit is growing. 
  • Pick off additional fruit once several fruits have formed. Ripening only one fruit at a time maximizes sweetness. The more fruit ripening on a vine at the same time, the less sweet they will be.
  • Do not prune off leaves or shoots. The leaves produce the sugars which sweeten the fruits. 
  • About a week before melons are ripe, cut back watering as much as possible to concentrate the fruit’s sugars. 
  • Harvest cantaloupe at the right time (see chart below). 

8. Harvest cantaloupe at the right time

Cantaloupe will continue to soften once picked, but it won’t get any sweeter. Leaving it on the vine as long as possible gives you the sweetest flavor.

9. Don’t let cantaloupe harvests go to waste

Melons last 3-5 days if left at room temperature. Uncut cantaloupe stored at 45℉ to 50℉ lasts up to 2 weeks. Once fruit is cut, it will keep for about 3 days in the refrigerator.

I completely uprooted my cantaloupe plant...bad...later in the day, I saw all leaves hanging down. I have about 7 that were growing. I found what was left of the root. Not much at all. I re buried what was left .I pretty much killed it didn't I? Ideas? One is just starting to vein up... will it continue if I pick it I doomed???? Can't believe it. Besides the obvious, if anyone has any helpful info, let me know. Thank you so very much. I'm devastated.

So sorry to hear that. You could pick the fruit and it will continue to ripen indoors.

We plant Ambrosia cantaloupe around May 15 in hopes of not getting a frost thereafter. However, we almost always get a frost into this year on June 1. We plant a patch about 20' by 45' on thick black plastic (lifetime of 30+ years) in holes 4-5 feet apart, drilled into the plastic with a hole saw. A couple of seeds per hole, sometimes 3 seeds. Fifty holes give us 120 plants, give or take. Last year, we harvested over 400 melons which we gave away to friends and neighbors, plus our own family eating a ton of cantaloupe. Then we took off for a long trip and had a neighbor harvest 50+ more before the Fall frost while we were gone. We were told we couldn't raise cantaloupe in our high desert climate due to the short growing season. We've proved "them" wrong and are doing it again this year. People tell us our cantaloupe are the best they've ever had in their life! There is more to this story....composted manure, automatic watering system, low or no maintenance, etc. I'm going to spray an Epsom salt solution on the cantaloupe tonight when the sun goes down. It's our little secret for super sweet-tasting and fast-growing melons. Growing cantaloupe is our favorite hobby!

@Bart Merrill, Would you happen to have a picture you could share? I’m interested in seeing the black plastic situation. Your garden sounds dreamy!

Wow! Thanks for sharing all your wisdom and cantaloupe with so many. Inspiring!

Angela, your calendar says to plant cantaloupe in june and july but this article says to plant in February? Can we plant twice in arizona?

You can plant from mid-February through July here in the low desert.

Do cantaloupe do well in containers with other vegetables? I'm thinking of planting some with my beans and summer squash.

Sure, as long as it is a large enough container, and you give it something to climb or allow it to spill over the sides. Cantaloupe vines grow large and can quickly overtake a container.
