Cucamelon Care

Cucamelon plants love warm weather, so summer in the South is an ideal environment for them. It’s best to plant them in the spring so they can germinate in plenty of time to enjoy the hot summer sun. You may want to grow them in pots to bring them indoors to keep warm when nighttime temperatures begin to drop. For daily care, cucamelon plants need full sun, regular watering, and well-drained soil to ensure they bear fruit. The cucamelon plant is a vine and will also need a trellis structure to climb as it grows. As a vine, it can spread and become invasive in areas when not correctly trained to climb a trellis or pruned.


Cucamelons need at least six to eight hours of direct sunlight daily to bear fruit. In some areas, cucamelons can tolerate partial shade, especially in the afternoon in hot climates.


Cucamelons grow in similar soil conditions as most vegetables, which means amending it with organic matter. If your soil quality does not contain rich, fertile nutrients, add compost and a layer of mulch to help enrich the planting area. The soil should be well-drained, slightly acidic, and humus-rich. Maintaining a consistently warm soil temperature will also help cucamelons to grow. As vines, cucamelons have shallow roots. Provide a trellis for them to have space to grow.
