How To Grow Cucumbers

Cucumbers are a tender heat loving plant that are part of the squash family along with melons, gherkins, courgettes and pumpkin. Unlike their butternut, winter squash, and pumpkin cousins they are not hardy, and need careful attention from the gardener to be successful.

How To Grow Cucumbers – Planting

Cucumbers are typically divided into indoor and outdoor types. Indoor types being typically longer and with thinner skins.

If there is a warm summer, and you purchase more hardy varieties, you may be able to successfully grow cucumbers outside. A sunny windowsill or a plastic greenhouse are cheaper options if you do not have access to a glass greenhouse.

When cucumbers are seedlings avoid over watering as this can kill the plants. I plant my cucumber seeds length ways on their ridges in already moist soil, cover with cling film, and then place on a warm windowsill to encourage germination.

Wait until the plant has several true leaves, and when the weather has warmed up during the day and night. Late June is the most likely time to transplant young cucumber plants outside. Prepare a hole with a good mixture of well rotten garden manure and compost.

How To Grow Cucumbers – Care

Cucumbers can be left to sprawl on the ground, or staked. The advantage of staking is that it means the fruit grow above the ground, and are therefore less likely to rot. If left to sprawl it is worth putting straw or cardboard under the fruit to keep them clean.

Cucumbers produce both male and female flowers. The key difference is that the male flowers do not have a baby fruit growing behind them.

It is recommended to:

  • Pinch out the male flowers if growing cucumbers indoors (this helps stop the fruit becoming bitter)
  • Leave the male flowers on outdoor growing cucumbers

It is possible to buy cucumber seeds cultivated to only produce female flowers. This is more expensive, but a good option for a busy gardener.

When cucumbers are in flower they should not be allowed to dry out. At this stage the plant is safe from the danger of over watering, providing their pot or soil has reasonable drainage.

The more cucumbers you pick the more active the plant will be. Therefore it is best to pick cucumbers when relatively small, 6″ or 15cm or so in length, to encourage more to come.
