What is the Mexican Sour Cucumber?

Commonly called cucamelons, this cute cucumber is identified by its startlingly similar appearance to a tiny watermelon. While small in size, the cucamelon has a satisfying crunch paired with a fresh citrus flavor. Imagine that clean cucumber taste with a whisper of lime.

History of the Mouse Melon

Mexican sour cucumbers are from the Cucurbit family and originate from Mexico and Central America. They were cultivated by the Indigenous groups of these regions, such as the Aztecs and the Mayans. In Central America, they are known as “sanditas”- little watermelons.

These mini mouse melons have been passed down through centuries, right to today’s modern gardens!


Only a little larger than a grape, this cucumber resembles a pinwheel filled with small, soft seeds when cut in half. They grow spaced out along delicate crawling vines and are mottled with patches of light green.

They can also be called a mouse melon or sour gherkin.

Optimal Conditions for Growth – Keeping them Happy

Before you begin planting, know that a happy Mexican sour cucumber thrives in sunny weather and loose soil. Keeping the soil moist, but not drenched is key. I recommend soil that is loamy or sandy for best results.

These plants prefer weather similar to their climate of origin. The late spring and summer months are optimal. You want the nights to be warm as well — frost is harmful to growth.

These vines can grow pretty long, so it’s best to consider a trellis or some form of support for the plant to climb.

How to Plant and Grow Cucamelons

The more desired option is to grow these fruits outdoors rather than inside. Cucamelons are delicate and do not transplant easily.

When planting, you can space out your seeds however you desire. A few inches apart, the plants are likely to grow together in a tangle of vines. They do well planted separately, or alongside other greenery as well.

These are fast-growing plants that fertilize on their own. They’re also drought-tolerant, so they pretty much take care of themselves. Just be sure they are getting around an inch of water each week. You should see a mature plant within 60 to 70 days.

Growing Season Care Tips

  • Partial shade is recommended in hot regions with intense sunlight.
  • Growing your plants on a trellis will help avoid potential pests and diseases, plus provide sturdy support.
  • Mix the soil with compost for nutrient richness.
  • To protect the young plant during colder weather, try covering them with a frost cover or cloche.

Winter Care

While it is possible to harvest the cucamelon seed to plant for the following year, there is a second option. The fruit’s roots have tubers about a foot down in the earth. These are perennial, and in the right conditions, will grow in the next season.

You can collect tubers and store them over the winter in a dark and cool place. Just be sure they won’t freeze where you place them.

Cellars or garages are a great place to store a container of tubers. Add some moist soil to the container and you’re all set. To replant the tubers, place them in soil about an inch or two down.

In warmer climates with mild winters, all you need to do is trim back the vines and you will see new buds the following growing season.

Where to Buy Seeds
