Best Vegetables to Grow in Exeter UK

Here are some of the best vegetables to grow in Exeter, UK:



It’s easy to grow broccoli in Exeter, UK. Broccolis thrive in more excellent areas, and it’s not a fan of excessive heat. You can grow it from transplants, starting from seedlings. However, broccolis need a lot of water. The soil should remain moist throughout the growing season. 

Broccolis attract harmful pests, including cabbage worms, root maggots, and aphids, so make sure to watch out for these critters. 



Just like broccoli, beets are a cool-season vegetable. They can even survive near-freezing temperatures! Beets grow quickly in well-prepared soil, and you can harvest them about two months after planting. Unlike other plants, you don’t have to deal with pests and disease problems when growing beets. 



If you think you can’t plant greens in Exeter’s cool climate, think again. Many green leafy vegetables grow well in Exeter, such as spinach, arugula, kale, and chard. Since you’re growing greens mainly for their leaves, you need to make sure that your soil contains plenty of nitrogen. Don’t forget to water them as well so they would grow fast. If your plant grows slowly, its leaves may turn out tough.

While greens can grow in Exeter, they can thrive better inside polytunnels. This allows your plants to stay clean and protected from rain and hail. 



Lettuce can easily grow in Exeter, UK. You can directly plant the seeds in your garden, but it’s easier if you plant them indoors. Lettuces don’t need direct sunlight to germinate. Additionally, you can easily transplant the seedlings. 

As with other types of greens, it’s essential to protect your lettuce from heavy rain and hail. Your soil should be consistently moist, and it should contain plenty of nitrogen to grow the best lettuce. Otherwise, it will taste not very pleasant. 



Cabbages also grow well in cool temperatures. Increasing them in humid areas may cause their heads to split before you get to harvest them. Since you need the cabbage for its leaves, the soil should also have a lot of nitrogen, and you should water it consistently. 



Potatoes are easy to grow, especially in light, sandy soil with minimal fertiliser and water. Plant your potato patch in sunny areas where they could (ideally) get at least six hours of sunlight per day for the best results. 



Carrots prefer to be planted in deep, loose soil during cool temperatures, preferably early spring and late autumn. If planted in heavy soil, your carrots will mature slowly, resulting in unattractive and rough roots.  Carrots should be seeded directly, and the soil should be kept moist so the surface never crusts over. You can place coconut fibres on top to retain moisture.



Tomatoes need at least eight hours of sun exposure. These plants have a long growing season, so it’s best to transplant them rather than seeding them directly into the garden. To grow sweet tomatoes, make sure to get the right balance of sun and heat. Since Exeter has a cooler climate, it’s best to grow your tomatoes in a polytunnel so you’ll be able to control the temperature. 

Growing Crops in a Polytunnel

Polytunnels enable you to control the climate inside the polytunnel, regardless of the current weather. This allows you to grow different types of plants that never would’ve survived in your area. You can even customise your polytunnel by adding a heating and cooling system, lights and shades, and ventilation. 

If you have larger polytunnels, you can divide them to create climate zones. In this way, you can grow different types of plants within the same structure. 

Many plants cannot survive in freezing temperatures, so be sure to pick your harvest immediately. You can protect immature fruits from mild frost using baskets, burlap, blankets, or canvas sacks. Since Exeter is prone to heavy rains, leafy plants are more vulnerable to pests and diseases. 

Heavy rainstorms can saturate the soil, attracting slugs and encouraging the spread of leaf diseases. Protect your garden from unwanted pests, rain, wind, and hail by using polytunnels. 

Other advantages of growing plants in a polytunnel include the following:


  • longer growing seasons
  • create an ideal growth environment
  • grow plants without dangerous pesticides
  • save energy
