What Can You Not Grow In A Polytunnel?

What Can You Not Grow In A Polytunnel

If you’re looking for a solution to the problem of not being able to grow certain things, you should consider using a polytunnel. It can be very effective if you use the right containers, which are a great way to grow plants in large polytunnels. Containers are great because they have head space and are less likely to attract insects and slugs. Containers can also be treated organically.

Plants that don’t grow well in a polytunnel

Some plants do not grow well in a polytunnels, while others will thrive there. For example, courgettes grow big and require a lot of space. It is not advisable to grow too many courgettes in a polytunnel, as they can become crowded. Bush tomatoes also require more space than vertically-trained varieties. They will also grow faster.

Another good reason to invest in a polytunnel is the extension of the growing season. Many plants will grow faster and mature quicker than they would in the open. French beans, for example, can be grown in a polytunnel before they would grow in a garden. This also means you can sow them later than normal and enjoy the fruits of their labour earlier.

One downside to polytunnels is that they don’t let in as much light as greenhouses do. A polytunnel’s green or opaque covering will allow in less light, so some plants may not thrive in a polytunnel. If you want your plants to grow well in a polytunnels, however, you’ll need to keep the climate controlled. The right kind of humidity will help your plants grow better.

Plants that attract insects

Many crops rely on pollinators to produce a good harvest. It’s important to provide plants that attract these creatures with suitable growing conditions. Some insects, such as bees and hoverflies, are particularly attracted to specific types of flowers.

Ants can be a nuisance, but they won’t hurt your crops if left alone. Just be careful not to disturb ants nests, as disturbed colonies can produce new queens. If you’re worried about ants, consider growing trap crops like sunflower. These plants attract ants and herd aphids onto them.
