How to protect plants in winter With the arrival of the cold we start to worry about how to protect plants in winter. Wind, frosts and of course snow can cause some of them to die, so it doesn’t hurt to be prepared to help them if necessary.
What to do in case of a frost warning
First, don’t be alarmed. Check which plants are most sensitive to low temperatures and prioritize their protection ahead of others. If, due to their size, it is easy to protect them at home during the night, place them in the kitchen or bathroom, where they will not notice an excessive temperature rise. Avoid placing them in the dining room or living room, where the thermal shock could be worse than leaving them on the balcony or terrace.
How to protect our plants in winter
Fortunately, they often invent new materials that facilitate the task of heating and protecting our plants.
The greenhouses are a perfect solution if you have enough space in the garden. They exist in the form of a small house, of various sizes, and also with structures that can be easily dismantled to be able to store them during the summer.
Place it in the place where it receives more hours of direct sunlight so that the plants can continue to grow without problems.
If you are a DIY enthusiast, you could even build one yourself, using wood, aluminum profiles and plastic sheeting for the greenhouse.
A very convenient option for those who grow on balconies and terraces are protective sheets. It is a very fine material which, spread on plants, increases its temperature by a few degrees. Furthermore, it allows its perspiration, irrigation, and reception of UV rays, which would not be possible with simple plastic. Once the cold is over, you can recover it, wash it and store it, waiting for the next year.
There are also bags in the same fabric, ideal for trees and shrubs in your garden or garden.
Beware of potted plants: they are the ones that suffer the most
The lesser amount of soil that the pots contain is much more sensitive to low temperatures than those planted in the soil. Also, the vessels ceramic or earthenware may break if the temperature change occurs abruptly.
To protect the jars, we recommend a very simple trick, which consists of covering them with cardboard or bubble wrap. Always leave drainage holes in case the situation lasts for many days.
We also advise you to move the pots and group them, as the plants suffer much less when they are close.
Start with the highest ones, placing them against a wall that receives direct sunlight, if possible. Then continue climbing, so that they all get enough light.
This distribution will also help you to place a protective sheet if necessary. You will be able to create a kind of tent (with the help of canes or braces planted in the largest pots) to protect them from the cold.
In winter, water in the morning
It is worth remembering that during the winter months it is advisable to water in the morning. During the day, temperatures tend to rise, so we minimize the risk of root freezing if the water freezes (which could happen if we water at night).
Two more tips: mulch and fertilizer
The mulch made of straw or pine bark helps to protect from the cold better our plants. Spread it over the substrate and forget about it, as it will still allow irrigation water to filter. During the winter it acts as a protective layer, while in the summer it prevents evaporation. It is very useful to get used to using it, especially in areas with extreme temperatures.
We conclude by suggesting the use of fertilizer rich in potassium and magnesium during the colder months. Although these two macronutrients are recommended to encourage the flowering of our plants, they will also serve them for greater resistance to cold.
