Frosts cause dehydration in plants as the roots are unable to absorb the necessary water. On the other hand, the formation of ice crystals in plant tissue can also cause significant damage. As winter has already arrived, we explain how to protect your plants from the upcoming frosts.
Low winter temperatures can damage plants, especially those that remain outside the home. In fact, when the temperatures drop too low, the main danger is not the branches or the leaves, since these tend to grow again with the arrival of spring, but the roots, which is the most sensitive part of the plant and, once damaged, it is difficult to recover.
Five tips to care for your plants in winter
- A decrease in irrigation. When temperatures drop too low, the water freezes, which affects the roots of the plant. In fact, did you know that seepage and freezing of water below the surface affect plants more than night frosts? Therefore, it is advisable that during the winter you waterless. In addition, you must make sure that the pots and planters have good drainage so that the water does not get trapped in the soil.
- Cover the plants. The bubble wrap normally used to protect fragile objects is also ideal for protecting plants. In fact, this material not only protects but is also insulating. Normal plastic is another alternative, although it must be transparent since this continues to bring light to the plant. In any case, during the day you must remove the plastic to prevent the plant from suffocating. You should also be careful that the plastic does not damage the leaves and stems, so it is preferable to place it on high stakes that support it.
- Group the plants. If the temperatures drop too low or the plants are very delicate, it is advisable to group them in one place, in order to cover them more easily. You can place them next to a wall, forming two or three rows and placing the highest plants at the end. Then you can install two stakes or stakes and cover the plants with a plastic film.
- Protect the earth with padding. When plants are in the garden you should protect them from frost, especially when it comes to very weak species. In that case, it is recommended to place a padded floor, which can be straw, dry leaves or pine bark. There are also artificial compounds on the market specially prepared to protect the roots of plants. This mulched soil also has an insulating action and helps to conserve the heat of the soil, preventing the roots from cooling and being able to continue absorbing the water and nutrients it needs from the soil.
- Avoid falling out of the pots. In winter the only risk to the plants is not the cold but also the wind. In addition to the damage that wind can do to the most fragile plants, it can also throw away the pots and break them. Therefore, it is recommended that in winter you place the pots next to a wall. You can also place stones, to make the pot more stable.
