Melothria scabra
A tender climbing plant grown for its tiny cucumber-like fruits. In the UK, start seed indoors, move plants out only after the last frost, and give them warmth, a sunny sheltered spot, and steady moisture for a reliable crop.
Step-by-step instructions for growing Cucamelon
Sow seeds from 28th March to 4th April on their edge in small pots of moist seed compost. Keep them warm at and do not sow too early, as young cucamelons dislike sitting root-bound. Cover the seed to a depth of .
From 10th April to 24th April, keep seedlings bright and evenly moist, and prick them out or pot them on before they become cramped. A small pot-up early is better than leaving them crowded, because cucamelons make fine roots but resent checks in growth.
From 4th April to 18th April, move plants outside for short spells in a sheltered place, then bring them back in at night. Do this gradually over about 10 days so they adjust without stalling.
Set plants out from 2nd May to 9th May after frost risk has passed, planting into rich soil or a large container on a slight mound. Water in thoroughly at once, then give each plant support so the stems stay off damp soil and the fruits are easier to pick.
From 19th June to 29th September, tie growth loosely to a trellis or canes and keep the soil evenly moist. Water at the base rather than over the foliage, as wet leaves encourage mildew and a wet stem base can rot.
Pick fruits from 14th July to 29th September while they are still small and firm, before the skins toughen. Harvest often, every 7 days or so, because regular picking keeps the plant cropping for longer.

Companion planting can deter pests, improve pollination, and make better use of space. Some plants confuse pests or attract beneficial insects; others improve soil or offer shade to neighbours that need it.
