Growing guide

Step-by-step instructions for growing Cucamelon

  1. 01

    Sow Seeds Indoors

    26 Apr to 3 May

    Sow seeds from 26th April to 3rd May 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 .

  2. 02

    Grow On Seedlings

    9 May to 23 May

    From 9th May to 23rd May, 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.

  3. 03

    Harden Off

    3 May to 17 May every 10 days

    From 3rd May to 17th May, 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.

  4. 04

    Plant Out

    31 May to 7 Jun

    Set plants out from 31st May to 7th June 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.

  5. 05

    Train and Water

    18 Jul to 9 Oct every 2 weeks

    From 18th July to 9th October, 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.

  6. 06

    Harvest Fruit

    12 Aug to 9 Oct every week

    Pick fruits from 12th August to 9th October 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.

Why companion planting matters

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.
