Can a 2m poly tunnel be used for growing potatoes?

Sep 11, 2026

Hey there, gardening enthusiasts! As a supplier of 2m poly tunnels, I often get asked if these bad boys can be used for growing potatoes. Well, you bet they can! In this blog, I'm gonna dive deep into the nitty - gritty of using a 2m poly tunnel for potato cultivation.

Why Consider a 2m Poly Tunnel?

First off, let me tell you a bit about 2m poly tunnels. They're a great option for both small - scale and medium - scale gardeners. They're not too big to manage, but they're also spacious enough to grow a decent amount of crops. And when it comes to potatoes, they offer some real advantages.

One of the main perks is the ability to control the environment. Potatoes are a bit finicky when it comes to temperature and moisture. With a 2m poly tunnel, you can keep the temperature just right, especially during those early spring months when the outside weather can be unpredictable. You can also protect your potato plants from heavy rain, strong winds, and even pests.

Preparing the Poly Tunnel

Before you start planting your potatoes in the 2m poly tunnel, you've got to get it ready. The first step is to choose the right location. Make sure the area gets plenty of sunlight, at least 6 hours a day. You also want to ensure good drainage. Potatoes don't like to sit in waterlogged soil, so if the ground is a bit soggy, consider raising the beds.

Next up, it's time to prep the soil. Potatoes thrive in loose, well - drained soil that's rich in organic matter. You can add some compost or well - rotted manure to the soil before planting. This will give your potatoes the nutrients they need to grow strong and healthy.

Planting Potatoes in a 2m Poly Tunnel

When it comes to planting potatoes in a 2m poly tunnel, timing is crucial. You can usually start planting earlier than you would in an open field. Aim to plant your seed potatoes in early spring, once the soil has warmed up a bit. You can even give them a head start by "chitting" them a few weeks before planting. This involves placing the seed potatoes in a cool, bright place until they start to sprout small buds.

When it's time to plant, dig a trench about 4 - 6 inches deep in your prepared soil. Place the seed potatoes in the trench, about 12 - 15 inches apart, with the sprouts facing up. Then, cover them with a few inches of soil. As the potato plants grow, you'll need to "earth up" the soil around the base of the plants. This helps protect the tubers from sunlight, which can turn them green and make them toxic.

Managing the Environment Inside the Tunnel

One of the keys to successful potato growing in a 2m poly tunnel is managing the environment. Temperature control is super important. Potatoes prefer a temperature range of around 60 - 70°F (15 - 21°C) during the day and a slightly cooler temperature at night. You can use ventilation systems, like vents and fans, to regulate the temperature inside the tunnel.

Moisture is another factor to keep an eye on. You want to keep the soil evenly moist, but not waterlogged. Over - watering can lead to diseases like potato blight, which can quickly wipe out your crop. You can use a drip irrigation system to ensure that your potatoes get the right amount of water.

Dealing with Pests and Diseases

Just like any other crop, potatoes in a 2m poly tunnel can be susceptible to pests and diseases. Some common pests include aphids, potato beetles, and wireworms. You can use natural pest control methods, like introducing beneficial insects or using insecticidal soaps, to keep these pests at bay.

Diseases like potato blight and scab can also be a problem. To prevent these diseases, make sure to keep the foliage dry, provide good ventilation, and rotate your crops every year. If you do notice signs of disease, remove the affected plants immediately to prevent the spread.

Harvesting Your Potatoes

After a few months of care and attention, it's finally time to harvest your potatoes. You'll know they're ready when the foliage starts to turn yellow and die back. Use a garden fork to gently dig up the potatoes, being careful not to damage them.

Once you've harvested your potatoes, you can store them in a cool, dark place. They'll keep for several months if stored properly.
