Companion Planting Cucumbers

Companion Planting Cucumbers

There are not many plants that don’t benefit from companion planting, which is another way of saying inter cropping. By companion planting cucumbers you will get less plant damage, healthier plants, and heavier crops.

How Does Companion Planting Cucumbers Work?

In some cases companion planting works by saving space, growing two or more plants that have the same requirements allows them all to grow successfully. Some plants will deter pests away from your cucumber plants, and some will attract beneficial pollinators. Whilst others will actually improve the health of your plants.

Companion Planting Cucumbers

Let’s get started with the good companion plants for cucumbers. In most cases the following will bring something of benefit to cucumber plants specifically. Some just make great companions that enjoy similar conditions.

Sweetcorn and Cucumbers

Cucumbers and sweetcorn enjoy the same growing conditions, that’s warmth, rich soil, and plenty of moisture. Try training your cucumber plants to grow up the sweetcorn thus saving space and ensuring similar conditions.

Beans and Cucumbers

Growing beans in companion with cucumbers works because all the nitrogen in the soil will be available for the cucumbers. This is because beans fix nitrogen in the air, and don’t need soil bound nitrogen. You can also try your own version of the 3 sisters method, using sweetcorn, beans, and cucumbers.

Sunflowers and Cucumbers

As sunflowers grow strong, tall stems, they make excellent companion plants for cucumbers. Train the cucumber plants to grow up the sunflowers using them as supports. Sunflowers attract many beneficial pollinating insects so you’re sure to get a good crop of cucumbers.

Carrots and Cucumbers

Cucumbers are fairly shallow rooted, whereas carrots have deep roots, making them ideal companion plants. Carrots also spend a considerable time in the soil, so you won’t disturb the cucumber roots when pulling your carrots.

Tomatoes and Cucumbers

Radishes and Cucumbers

Radishes deter cucumber beetles

These fast growing little beauties not only help to suppress weeds, they’re much more beneficial than that. Radishes deter cucumber beetles, however, radishes don’t do too well in high temperatures. So get them in and out before it hots up, just let a few go to seed for repellent duties.

Lettuce and Cucumbers

Broccoli and Cucumbers

Cucumbers and broccoli will grow well as companion plants. The shade provided by the cucumber plant as it grows, will help the broccoli in the hot sunshine. Grow dill alongside to attract many useful insects.

Cauliflowers and Cucumbers

Peas and Cucumbers

As peas are a member of the legume family, like beans, they will work in the same way as beans in companion to cucumbers. Allow the pea vines to twine up the same supports as the cucumbers.

Dill and Cucumbers

dill also known as the cucumber herb

Dill is also known as the cucumber herb. Once dill is in bloom it will attract beneficial insects, pollinators like bees and hoverflies, and predators like hoverfly larvae, ladybirds(bugs) and parasitic wasps.

Marjoram and Cucumbers

Marigolds and Cucumbers

Petunias and Cucumbers

petunias are very versatile companion plants

These can be used to repel leafhoppers, aphids, and general garden pests. Petunias can be grown with just about anything, but work well with cucumbers.

Sage and Cucumbers

Due to it’s strong aroma, sage should not be grown anywhere near cucumbers. The cucumbers flavour can be affected by the sage.

Mint and Cucumbers

Another combination that doesn’t work is cucumbers and mint. Again this is due to the strong scent exuded from mint.

Melons and Cucumbers

There are many theories as to why these shouldn’t be grown together, and many of them are false! The truth is, they are both hungry crops and if grown too close they would be vying for the same nutrients. This would mean one or both plants will suffer and ultimately fail.

Squash and Cucumbers

Another combination that doesn’t work and for exactly the same reason as above.

Rue and Cucumbers

don't grow rue with cucumbers

Rue is a very effective pest repellent, but unfortunately, if planted near cucumbers it will slow the cucumbers growth. Meaning less fruit and possibly disformed plants and fruit.

Potatoes and Cucumbers

Again there is a lot of speculation concerning the reason why these 2 shouldn’t be grown together. They are both hungry crops, so that’s one reason, but the main problem, is blight. Potato blight can be devastating to your potato crop and cucumbers can encourage potato blight.
