Grow Cucumbers Outdoors In The UK With Harvesting Tips

Last Updated on March 23, 2022 by Real Men Sow

Not got a greenhouse to grow proper long, smooth cues? How about trying growing cucumbers outdoors? I started growing outdoor cucumbers on my first allotment when I didn’t have a greenhouse.

Cucumbers were a roaring success, and they’ve been one of the first seeds down on my growing list ever since. I’ve just harvested my first outdoor cucumber for this season, having started the seed off back in April. In this post, I’ll share with you the best gardening tips to plant your cucumber seeds the right way.

How to Grow Cucumbers Outdoors

Pick The Cues Small

Essentially they’re big gherkins and share the same rough skins but the idea is not to let them grow to the same size as the cucumbers you’d find in the shops. I pick mine when they’re about 6 inches long, or half the length of a conventional cucumber.

Bush varieties are available, but I prefer the trailing vine types, such as the tremendously named Burpless Tasty Green. This variety can trail to almost 3 metres and makes for an attractive spectacle in a veg bed.

Grow Cucumbers Upwards or Let them Trail

You can grow the cucumbers upwards, training the vine against a net or structure, or let the plant take its natural course along the ground. I plant the cucumbers in the corners of my raised beds and then guide them to where I want them as the vines begin to sprawl. I sometimes use little sticks to help with this, especially if I’m trying to trail them around my pathways.

How To Grow Cucumber Plants from Seed

The seeds do need a temperature of above 20 degrees to germinate. I grew seedlings in pots in my greenhouse, but you could easily do this on a sunny windowsill or under a cold frame.

What temperature is best for growing cucumbers?

Once the seedlings are ready to go out, the cues will happily grow in temperatures around 15 degrees Celcius so make great alternatives if you don’t have a space under glass.

I plant out in a recess (like my squashes) so the water stays in and around the plant where it’s needed. This also helps me water underneath the leaves rather than on top of them.

Like squashes, it can be worth putting straw under the fruits to stop rotting and colouration. A small handful, just to keep the fruit off the surface is perfect. I’ve found the slugs stay away too – I’m guessing they don’t like the coarseness of the straw.

When to Harvest Cucumbers

Each plant should give you 10 or so fruits during the summer, especially if you water regularly. Once the season is over, try pickling any small fruits left on the plants as they’ll make a nice Winter gherkin treat.

Only one little word of warning though – don’t expect beautifully straight and smooth specimens. These cues are a little like proper cucumber’s ugly sister. Don’t be put off though; they taste every bit as good.

Hello, I’m Pete and I’m currently based in the west of Scotland, in a small place called Rosneath, where I’m exploring my garden adventures. I personally started gardening around 6 years ago and initially, I started out by growing my favorite fruits and berries, such as strawberries, Raspberries & Gooseberries. Since then I’ve added a lot of vegetables and working closely with my neighbor, it’s been a lot of fun.
