Propagating Cucamelons

As cucamelon plants are not very popular, finding their seeds at a local store or nursery may be difficult. If you do, however, seedlings are preferable to seed. Another way to get your hands on the seeds is online.

When the ripe fruit falls from the plant, keep it in a cool place. After two weeks, slice the fruit in half and collect the seeds. Keep these seeds in a jar filled with water for about a week. After that, dry them on a paper towel; that’s it! Your seeds are ready to use.

Note: It is always a good idea to sow seeds directly in the desired location or in 4 inches separate pots.

Growing Cucamelons in Pots

You can grow one or two plants in a 5 to 7-gallon pot (12-14 inches container). A 24 inches pot is good for growing 3-4 cucamelon vines. Make sure that the container has sufficient drainage holes. Amend the soil with plenty of organic matter.

Tip: If you are growing multiple plants, keep the containers 1-2 feet apart and provide support.

Requirements for Growing Cucamelons

Location

Cucamelons thrive in warmer conditions. You should plant them where they get at least 6 hours of sunlight daily. Planting them in the shade will result in lesser fruits.

Soil

Just like all fruiting plants, cucamelons also need nutrient-rich soil with good drainage. You can use organic matter and compost. For more details, check out our article on making DIY potting mix here.

Watering

Even in hot climatic conditions, cucamelons do not require watering daily, thanks to their water-storing ability in their roots in the form of tubers. In warm weather, you can water the plant once a week.

During cold days or when fog and clouds obstruct the sun for a prolonged period, water the plants only when the topsoil becomes dry.

Note: Overwatering can cause decaying of the roots, so avoid it.

Climatic Conditions

Cucamelon prefers warm growing conditions, but this does not mean that you can’t grow them in colder climates. Plant them after all the dangers of frost have passed.

Cucamelon Care

Use a Trellis or Wire Cage

Cucamelons can grow up to 7-10 feet in length and need a stable and robust structure to thrive. You can install a trellis or wire in the form of a mesh or cage.

This will not only act as a support structure but will also help you grow plants in any way you desire. Furthermore, the trellis is also going to help you in keeping the stem and fruits off the ground.

Fertilizer

The best time to fertilize the plant is when the flowers start to appear. Using fish emulsion in small amounts, once a week, is a good start. This is going to make sure the cucamelon production remains prolific. Alternatively, you can also use bonemeal.

Tip: Avoid using high nitrogen fertilizers as they might hamper the fruit production of the plant.

Pest and Diseases

Surprisingly, cucamelons are not prone to pests and diseases. As long as they’re off the ground. They do not require pest control measures. Yes! You heard it right! Due to some unknown reasons, pests leave cucamelons alone, and even birds steer clear of them!

Note: The plant is not susceptible to pests. However, it can be affected by root-knot nematodes.

Harvesting Cucamelons

Fruits start to appear just after 2 to 3 weeks of flowering. Pick them when they’re nice and firm, about one to one and a half-inch in length.

Harvesting cucamelons is no different than picking cucumbers. They are also very easy to store, thanks to their size! As long as you are going to keep them at room temperature, they’re going to do just fine.

However, over time, they’ll lose their crunchiness. Harvest some fruits a little earlier than their fruiting time, as it increases the production. Here are some of the ways you can use cucamelons:

• You can eat them fresh. You don’t even have to peel them off!
• Cucamelon pickle can be used in sandwiches and wraps.
• They can be used to garnish cocktails or lemonades.
• You can also add them to salads to have a citrusy and crunchy flavor!
