Can You Grow Potatoes In A Polytunnel

Whether you’re a beginner or a pro, there are a few things to keep in mind when planting potatoes in a polytunnel. In this article, we’ll take a look at harvesting, cleaning, and early and second earlies. You’ll also learn how to avoid common mistakes when growing potatoes in a polytunnel.

Early varieties

Getting an early start on the potato crop can give you a quick return. There are several different ways to grow potatoes, including in a polytunnel, greenhouse, grow bags, and containers. All these methods require the same basic requirements: a sunny, well-drained area, the right compost, and enough space.

The best time to plant early varieties is in the spring or early summer. This is when they will be ready to harvest. They are also less susceptible to diseases.

Early varieties are best planted in a polytunnel, although they can also be grown in a greenhouse or in large containers. These varieties should be planted at least 30cm apart. Watering is also important. Watering the potatoes regularly will help improve the quality of the tubers.

If you live in a colder climate, some varieties have been developed to tolerate the cold. These include the International Kidney potato, which is harvested in June. It has a white waxy flesh that makes it suitable for boiling or baking. It also has a good flavour.

Second earlies

During summer, polytunnels are a great place to grow a range of cool weather crops. They provide an excellent growing environment for perennials, cut and come again crops, as well as exotic crops. They can even be used for growing potatoes.

Polytunnels can also be used to grow a variety of winter crops. Many people grow potatoes in these tunnels. They can also produce a wide range of healthy vegetables and herbs.

Polytunnels are particularly useful for crops that require a longer growing season. Squash is one example. They are planted in early summer and then moved into a greenhouse before frost hits.

Another example is the tomato. It can be planted in a polytunnel and kept outside for a few weeks. This gives the seedlings a chance to get a little sun. They should be covered with a fleece at night. Watering the tomatoes from the top of the pot will help prevent them from drying out.


Depending on the variety of potato you are growing, there are various methods of harvesting potatoes. If you are harvesting a new variety, you may want to leave them in the ground for several days after harvesting, so the flesh remains firm. You can also harvest them as you need them.

There are three types of potatoes – the first early, second early, and main crop. These types differ in size and maturity.

For early varieties, it is important to plant your potatoes 6-8 weeks before the average last frost date. Depending on your location, you may be able to plant potatoes as early as late February. If you are able to plant them earlier, you can harvest them as early as three months after planting.

For late crop varieties, you may be able to plant them as early as August. You can also grow these varieties in polytunnels. It is important to use black polythene to warm the soil. This will make the soil more conducive to sprouting.


Having a clean polytunnel is one of the best ways to start off the growing season. It allows you to clean out any debris, weeds and dead plant material from the structure. It also makes the structure more attractive and easier to work with. It also keeps the polythene in good condition and helps prevent disease.

The process of cleaning a polytunnel isn’t complicated, but it is an important step. By removing dirt and dead plant material, you can prevent disease from taking hold. You can also increase the life span of the structure. By removing clutter, you also eliminate a place for insects and other pests to hide. You can also increase air circulation and improve the overall health of your garden.

Before starting the process of cleaning a polytunnel, you’ll need to prepare the area. This involves removing stubborn perennial weeds and adding organic matter to the soil. For early spring crops, you’ll need to fill the area with compost. This can be done using homemade compost or imported top soil.
