How To Grow

Growing cucumbers from seed is a brilliant way to enjoy fresh, flavour-packed harvests straight from your garden or greenhouse. These productive plants are easy to grow, quick to establish, and a joy to pick once the season gets going.


Indoor Sowing
Start seeds indoors from April, sowing into small pots of quality seed compost mixed with about 25% vermiculite for moisture retention. Keep them warm and bright on a sunny windowsill or in a heated propagator. Once seedlings develop a few true leaves and the risk of frost has passed, harden them off before moving outdoors or into a greenhouse.


Planting Out
Harden seedlings gradually over 7–14 days, placing them outside for a few hours each day. Transplant into larger pots, growbags, or beds in fertile, well-drained soil in a sheltered sunny spot. Allow 45cm between plants and 45cm between rows.


Outdoor Sowing
Direct sow from late May to June, when soil is warm and frost-free. Cover seeds lightly and water well. This method suits warmer regions, though indoor sowing gives a more reliable start in cooler areas.


Harvesting
Cut cucumbers from the vine with a sharp knife or scissors to avoid damaging plants. Harvest regularly to encourage continuous cropping.


Companion Planting
Grow cucumbers alongside marigolds, nasturtiums or radishes to deter pests and support healthier growth.
