Cucamelon Seeds

How to grow Cucamelon

Seed Sowing

Sow in pots under cover from March – May.

Transplanting

Cucamelons will benefit from being grown under cover in a polytunnel or greenhouse, but can be hardened off and grown outdoors in a well sheltered, south-facing spot.

Transplant your seedlings under cover into a polytunnel or greenhouse in April or May. Alternatively plant outside in their growing position in May when the risk of frost has passed.

Plant Care

Cucamelons will need to be grown up netting or a trellis and can reach up to 2m in height. Keep the area weed-free and consistently watered during hot spells. You can mulch around the plants to keep in moisture and prevent weeds.

Trim back any dead foliage to increase ventilation and prevent diseases.

Challenges

Cucamelons are generally pest and disease-free but can be prone to powdery mildew or aphids.

Harvest

Harvest the fruits when they are about the size of a grape but still firm to touch. They are best eaten straight away but will store in a fridge for up to a week.

Culinary Ideas

Cucamelons have a tart, citrusy flavour and are incredibly crunchy and refreshing when eaten raw in salads, as a garnish or as a pickle.

Seed Saving

A population of at least five plants is recommended, although it is possible to save seed from just one plant. Each fruit contains up to 50 seeds, so very minimal harvests are needed for a plentiful seed crop.

Cut the fruits across the equator, squeezing out the juice and seeds into a jar with a little water inside. The seeds will settle to the bottom of the container. Cover the jar with a breathable lid, like a kitchen towel or muslin and leave to ferment for up to 5 days. Remove any mould that may have formed and any seeds on the surface. Pour into a strainer and rinse with water, placing on a screen to dry in a well ventilated, cool area.

Store seeds in a cool dark place once fully dried.
