Outdoors in containers - 2.5cm/1" deep on its side in large  containers at least 30cm/12" wide  or 2 per growbag 

Outdoors in open ground - 3 seeds per station, 5cm/1" deep on their sides at least 45cm/18 inches apart on all sides.

After Germination

Keep well watered but not too wet

Growing on -  in Containers

Harden off indoor sown plants then transplant to large containers  at least 30cm/12" wide for each plant  or 2 per growbag

Growing on -  in Greenhouses

Transplant to large containers at least 30cm/12" wide for each plant or 2 per growbag

Growing on -  in Open ground Remove the 2 weakest seedlings at each station to leave 1 strong seedling.

Aftercare

Outdoor Varieties - Pinch out growing tips after 6 or 7 leaves have developed. This will produce side shoots. These can be left to trail on the ground or trained up netting. Keep very well watered but only water around the plants and feed with liquid fertiliser when the fruits begin to form. 

 

Greenhouse Varieties - Train the stem up up vertical wires or canes and pinch out the tip once it has reached the roof. Pinch out the tips of any side shoots 2 leaves after a female flower (these have very small cucumbers behind them whereas male flowers are just on stalks). Remove all male flowers as they appear.

 

Keep very well watered but only water around the plants and feed with liquid fertiliser when the fruits begin to form.

 

Keep the atmosphere as humid and ventilated as possible. Spraying down the floor helps.

Harvesting

Cut normal cucumbers at 15-20cm/6-8" and gherkin types at  5-7.5cm/2-3". Continual cropping is essential to encourage new more cucumbers to develop. Cropping continues over many weeks.

If you know aphids are a problem in your area, grow flowers such as nasturtiums, calendula asters,  dahlias, and zinnias nearby as  they act as a lure.

 

 

Create a bio-diverse environment by planting flowers nearby to attract bees, ladybirds and other "friendlies". To learn more about companion planting click here.

In the Kitchen

Storage:  Refrigerate for up to 5 days
