Sow and Plant

Start seeds indoors and expect seeds to germinate after 7 to 10 days. Set plants out after the soil warms when they are 3 to 4 weeks old. Cucamelons are tropical plants that grow best under warm conditions. Use horticultural fleece to protect plants from chilly spring weather in colder areas. Where summers are hot, cucamelons can be planted in late summer for harvesting in the autumn. The seeds germinate quickly in warm soil.
Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area.


Use a sturdy trellis to save space, and to make the little cucamelons easier or to harvest. Cucamelon vines resemble cucumber vines, but with smaller leaves on vines that can run to 3m (10 feet).


Cucamelons have a mild lemony zing when harvested young, when they are the size of large grapes. Larger, older fruits can be used for pickles. Pick cucamelons at least every other day, and refrigerate fruits after harvesting. Fruits with hard seeds inside are overripe.


Cucamelons are of little interest to insect pests, but old plants can develop powdery mildew late in the season.
