Cucamelons are native to Mexico and Central America and are open-pollinated, grape-sized cucumber cousins. They are known as Mexican sour gherkins or mouse melons. They look like tiny watermelons (on the outside) and have a cucumber-lime flavour. Their lush vines will need support (trellis or fence) and can grow as high as 1.2-1.5 m (40 to 50”) tall with a spread around 10-15 cm (4-6”) wide. They are ready to use when they are grape-size and still firm to the touch. They are easy to grow and a vigorous climber/trailer.
Cucamelons, also known as Mexican Sour Gherkins, are small, cucumber-like fruits that are easy to grow from seed. They prefer full sun and well-drained soil. Start seeds indoors 4-6 weeks before your last expected frost date, or direct sow seeds in the garden after all danger of frost has passed. Plant seeds 1.5-2.5cm (0.5-1”) deep, spaced 60-90cm (24-36”) apart in rows spaced 90-120cm (36-48”) apart. Cucamelon vines can grow up to 2m (6.5ft) long, so provide support for the vines to climb, such as trellises or fences. Water regularly and deeply, keeping the soil consistently moist but not waterlogged. Fertilize with a balanced fertilizer every 3-4 weeks during the growing season. Cucamelons are ready to harvest when they are about the size of a grape and have a slightly yellow or brown tint. Pick cucamelons frequently to encourage more fruit production.
