What are the best tomato varieties for a 3x2 polytunnel?
Jul 22, 2026
Hey there, fellow gardening enthusiasts! If you've got a 3x2 polytunnel, you're in for a treat. Polytunnels are amazing for growing all sorts of plants, especially tomatoes. They create a micro - climate that protects your plants from harsh weather and pests, giving you a better chance of a bountiful harvest. As a 3x2 polytunnel supplier, I've seen firsthand how different tomato varieties perform in these setups. So, let's dive into the best tomato varieties for your 3x2 polytunnel.
1. 'Gardener's Delight'
This one's a classic, and for good reason. 'Gardener's Delight' is a cherry tomato variety that's super sweet and juicy. It's a real favorite among home gardeners. The plants are indeterminate, which means they'll keep growing and producing fruit throughout the growing season. In a 3x2 polytunnel, they'll need a bit of support, like a trellis or stakes, but it's totally worth it.
The fruits are small, about the size of a cherry, and they come in clusters. You'll be able to pick them straight off the vine and pop them into your mouth. They're perfect for salads, snacking, or even whipping up a quick tomato sauce. 'Gardener's Delight' is also quite disease - resistant, which is a huge plus in a polytunnel environment. You won't have to worry too much about common tomato diseases like blight.
2. 'Tumbling Tom'
If you're short on space in your 3x2 polytunnel, 'Tumbling Tom' is an excellent choice. These are determinate plants, which means they have a more compact growth habit. They're perfect for growing in hanging baskets or containers within the polytunnel.
The tomatoes are red and round, with a lovely sweet flavor. The plants are really productive, and they'll spill over the edges of the containers, creating a beautiful cascading effect. You can place them near the edges of the polytunnel to make the most of the available space. And since they don't grow too tall, you won't have to worry about them taking up too much vertical space.


3. 'Moneymaker'
Another well - known variety, 'Moneymaker' is an indeterminate tomato. It's been around for ages and is a reliable producer. The fruits are medium - sized, with a good balance of sweetness and acidity. They're great for slicing and using in sandwiches or making tomato juice.
In a 3x2 polytunnel, 'Moneymaker' plants will need proper support as they can grow quite tall. But once you've got them set up, they'll reward you with a steady supply of tomatoes throughout the season. This variety is also relatively easy to grow, making it suitable for beginners and experienced gardeners alike.
4. 'Sungold'
'Sungold' is a cherry tomato variety that's a real showstopper. The fruits are a beautiful orange color and have an incredibly sweet flavor. They're often described as having a tropical taste, which is quite unique for a tomato.
The plants are indeterminate, so they'll need some support. They're also very productive, and you'll find yourself with a lot of these delicious tomatoes. In a 3x2 polytunnel, they'll thrive in the warm and protected environment. You can use them in all sorts of dishes, or just eat them straight from the plant.
5. 'San Marzano'
If you're into making your own tomato sauce or paste, 'San Marzano' is the variety for you. These are plum tomatoes, which are known for their meaty texture and low water content. They're perfect for cooking down into a rich, thick sauce.
The plants are determinate, so they have a more compact growth. In a 3x2 polytunnel, you can grow a few of these plants to get a good supply for your cooking needs. The fruits are long and oval - shaped, and they have a wonderful flavor that's perfect for Italian - style dishes.
Tips for Growing Tomatoes in a 3x2 Polytunnel
- Temperature Control: Make sure to monitor the temperature inside the polytunnel. Tomatoes like it warm, but not too hot. You can use ventilation to keep the temperature in the right range.
- Watering: Tomatoes need consistent watering. Don't let the soil dry out completely, but also don't over - water. You can use a drip irrigation system to make watering easier and more efficient.
- Fertilizing: Use a balanced fertilizer to keep your tomato plants healthy. You can also add some compost to the soil before planting to give them a good start.
