What Veg Can You Grow In Polytunnel In Winter?

What Veg Can You Grow In Polytunnel In Winter

When the weather is cold and wet, vegetables can be difficult to grow. Luckily, there are ways to grow these crops in a polytunnel or greenhouse to make sure they will survive the winter months. The best vegetables to grow in a polytunnel or greenhouse are potatoes, beans, lettuce, kale, and swede.

Growing round peas

Growing round peas in a polytunnel is an excellent way to enjoy a steady supply throughout the winter months. You should avoid watering them too much in the winter months, as this can cause rot and disease. For best results, you should also save your seeds for next year. You can do this from your garden peas and broad beans to ensure a better crop the following year.

The best time to sow round peas in your polytunnel is in autumn. In mild climates, you can sow them in early September. Then, they will produce early crops in the spring.

Growing kale

Growing kale indoors is one way to grow this nutritious vegetable in winter. However, you will need to take a couple of extra steps to make it as successful as possible. First, you must have enough light and water for the seedlings to grow. Secondly, you need to mulch the soil with hay or straw to stop the evaporation of moisture. Finally, you need to water the kale plants regularly. Kale needs about one inch of water per week. If this is not possible, you can use grow lights to provide additional illumination. Finally, remember that harvesting kale in winter should start with the outer leaves. This will allow the inner leaves to continue growing.

After planting kale, wait 50 to 60 days for the leaves to mature. Once the plants have reached this maturity stage, they can be harvested. They can be used in soups and as kale chips. Winter kale should be planted in a sunny spot with lots of sunlight. It should also be grown in soil that is rich in organic matter. This will help feed the plant during the warmer seasons.

Growing swede

You can grow swedes in a polytunnel during winter and they need a slightly warm climate to thrive. The seeds can be sown ten to twelve days after the last frost in your area. After the seedlings have been sown, they should be planted out with a 25cm spacing between each plant. This will allow the plants to set roots and produce more leaves.

Swedes need plenty of moisture to grow and should be watered regularly. They can become bitter if their roots are dried out. It is a good idea to keep watering deep, as the water needs to reach the roots. Swedes do not require heavy fertiliser, so a general-purpose organic fertiliser is the best option. You can also use fish, blood and bone to give them a little extra boost.

Growing radishes

Growing radishes in a polytunnel in winter is an easy and productive way of ensuring you’ll have a constant supply of nutritious and tasty salad leaves. Radishes grow fast and are an excellent choice for any vegetable garden. They grow in a variety of shapes, colours and sizes and are a great addition to any salad dish. While radishes are commonly eaten raw, they are also grown for their edible seeds. The unripe seed contains a delicious flavour reminiscent of mange tout and a slight radish bite.

Radishes can be harvested from three to ten days after sowing, so a little bit of preparation is required. When they sprout, thin the plants to about 1.5-2 inches apart. If you don’t thin your radishes, they’ll grow too large and develop stunted roots.

Growing kale in a polytunnel

Growing kale indoors in a polytunnel can be a great way to grow this popular vegetable. Kale doesn’t need much water during the winter and can grow well without fertilizers. Kale requires plenty of light, so it can be grown in a south-facing window or with grow lights. During the winter months, harvest the outer leaves first. This will give the inner leaves more time to grow.

Before you plant, prepare your polytunnel for the winter. Make sure it is clean and ready for sunlight. Once it is ready, start planting your winter vegetables. You can use a row cover to protect the plants from frost.
