  • The leaves of the Comfrey plant can be used to make a nutrient rich liquid fertilizer ideal for giving a nutrient boost for cucumber plants.

Sowing Guide

Early Sowing/Module Sowing

Sow 1 seed on its side per 5 - 7 cm plastic or biodegradable pot at the depth suggested above. Ensure enough heat is introduced for good germination. Once the seedlings have germinated move to a warm area with good daylight exposure. Keep the compost moist but do not overwater. The seedlings should be ready to plant out into their final growing position 3 - 4 weeks after sowing.
Plant 1 cucumber plant per large container or 2 plants per large growbag. Carefully firm the compost or soil around each plant and water well. If growing direct in the ground plant 45 cm apart.
Greenhouse cucumbers like Pepinex must be grown in a warm humid greenhouse or polytunnel with a minimum temperature of 15°c.

Direct Sowing

This variety in not suitable for growing outdoors in the UK.

Growing On

Keep the soil moist. When watering, water around the base of the plants rather than over its leaves. Greenhouse varieties do not need pollinating. To prevent pollination happening (as this will produce fruit with a bitter flavour) all the male flowers should be removed. However as Pepinex is an all female variety no male flowers are produced (so identifying and removing male flowers is not necessary in this case :)
The main shoots of the cucumber plants will need to be trained onto a 1.8m cane or string (attached to the roof of the greenhouse). Loosely tie the stem to the support. When they reach the top of their supports, to stop them growing any taller, pinch out the growing points at the top of each plant.
Once the cucumbers begin to develop, the end of each side shoot will need to be pinched out leaving only two leaves after each fruit. Doing this will help to encourage more side-shoots to grow (which will encourage more cucumbers to grow)
Cucumbers like humid conditions. During the peak of summer wet the floor of the greenhouse with water on a regular basis to keep the conditions humid.


The first cucumbers can be ready to harvest around 10 - 12 weeks after sowing.
Cucumbers are best harvested when young and tender.
To harvest, cut with a sharp knife, secateurs or scissors. Do not pull the fruit off the plant as this can easily damage the brittle stems. Greenhouse cucumber varieties can produce fruit well into October (depending on the temperature).
Harvesting regularly will encourage more cucumbers to grow.


Cucumber plants are heavy feeders. When the fruits start to swell they will benefit from a liquid feed every 2 - 3 weeks. The leaves of the comfrey plant when steeped in water for a few weeks produces an excellent nutrient rich organic fertiliser especially suitable for fruiting plants.
