What Can You Not Grow In A Polytunnel?

What Can You Not Grow In A Polytunnel

If you have a polytunnel, it is possible to grow a variety of crops that are hard to grow in the open air. These include annuals and perennial crops. Some of the most popular crops to grow in a polytunnel include asparagus and globe artichokes. They will grow faster and healthier inside the polytunnel than they would outdoors.

Growing vegetables

Vegetables that are best suited to growing in a polytunnel are winter-hardy plants like broad beans. These are easy to grow and can be sown directly into the ground in your polytunnel. Other good options include kale, which is weather hardy and is easy to grow. Carrots can also be grown in a polytunnel, and are a great late-season choice. To get the best out of carrots, plant them at 10cm apart and keep them moist.

If you want to grow vegetables all year round, you can start seedlings in the autumn. You can plant lettuces in grow bags, as well as parsley, French beans, and calabrese. As soon as the clay soil becomes more manageable, you can transplant your plants outdoors. Broad beans, pea shoots, and courgettes can be planted in the spring and summer.

Growing herbs

If you’ve got a polytunnel, you can grow just about any herb. You just have to know what each of them requires in order to grow well. For example, rosemary likes a free-draining soil and full sun. Parsley and basil need more moisture and prefer some shade in the summer.

Herbs grow best in a well-drained soil that allows them to develop a strong root system. You can give them a little fertilizer and water occasionally, but make sure that the soil doesn’t get too dry. In fact, herbs need a little moisture even if they’re indoors.

Herbs that are easy to grow include cilantro and parsley. They have various medicinal properties and are good for digestion. Psyllium is also good for the colon and helps regulate cholesterol levels and blood pressure. Psyllium can be planted with six-inch-spacing and full sun.

Growing onions

Onions are ideal for growing in a polytunnel, because they are easily grown from seed. They should be sown 2cm deep and one inch apart in moist soil. Sets should be sown in late March or early April. The soil should be moist but not wet. Planting sets of onions in mid to late March is recommended. The sets should be positioned 10cm apart with the neck upwards, and the soil surface should be just slightly damp.

If you live in a cold climate, growing onions in a polytunnel is a good option if you’d like to grow them in a protected environment. In addition to providing better protection, polytunnels can help you extend the growing season. In addition, a polytunnel is not permanently fixed and you can easily move it around and take it down in the winter. You can grow a small hobby tunnel for a kitchen garden or a larger one for a vegetable or plant nursery. Growing onions in a polytunnell can help you grow your crop in a protected environment and produce a high yield.

Growing turnips

If you’re planning to grow turnips in your polytunnel, you’ll need to ensure that your soil is rich in organic matter. This will help to give your turnips the vital nutrients they need. It’s also essential that your soil is well-drained and cool. Turnips will bolt if they get too hot, so planting them in the shade is essential. In addition, it’s important to avoid planting turnips in areas where they’ll be competing with other crops.

There are several varieties of turnips you can grow in your polytunnel. The globular types are suitable for growing in winter, while the longer ones are best for the summer. Both varieties are edible and are suitable for growing in a polytunnel.
