During the winter months, it is essential to protect your plants. This can be done using mini polytunnels, horticultural fleece, bubble wrap and row covers. You can also cover individual plants with cloches made of plastic packaging. This will protect the plant from damaging frost.
When it’s cold outside, growing vegetables in a polytunnel is a fantastic way to extend your harvest. If you’re growing vegetables for winter consumption, kale is a great choice. You can start them indoors in a propagator or small pot before transferring them to your polytunnel. Once they’re two inches tall, you can transplant them to the polytunnel. Be sure to water well and label them with their names.
Using a polytunnel to grow perennials in winter is an easy way to extend your growing season and produce larger crops. These structures are easily installed and come with an integrated cover made from UV stable polythene. In addition, the construction is made from stainless steel and includes a pre-assembled frame that allows you to get up and running quickly.
Growing flowers in a polytunnel
If you live in an area that has a cold winter, it may be tempting to grow flowers inside your polytunnel in winter. These containers can provide warmth to the soil during winter and allow you to grow different plants that are not possible outside. If you plan to grow plants in a polytunnel during the winter, make sure you prepare it properly. Make sure it is clean to allow maximum sunlight.
Protecting your plants from frost
Protecting your plants from frost in a polytunnel is an important aspect of growing plants in your polytunnel. There are many options available to you. One of the cheapest solutions is to use straw mulch. This material is often available locally and acts as a thermal insulator. When laid on top of the soil, it keeps the area warmer on cold days and cooler on hot days. However, it is worth remembering that some crops are not suited to straw mulch and you may need to check what effect it will have on your crops.
Keeping the temperature above freezing
If the temperature inside your polytunnel is below freezing, you may want to consider installing a heating system. These systems can provide extra heating for your crops during cold nights and reduce heat loss in the day. If you have a large polytunnel, you can also use a ground-source heat pump to take advantage of the heat energy from below the ground.
During winter, ventilation in a polytunnel can be crucial. Ventilation is essential to reduce the risk of heat-related damage to plants. Proper ventilation also helps the polytunnel to cool down gradually at night.
Proper lighting for your polytunnel is essential for growing crops over the winter. You need to make sure that the structure is well-prepared and clean to get the most sunlight possible.
