Winter management of foliage plants

The foliage plants are prolific in the tropical and subtropical regions. In order to allow them to spend the cold winter in the north and maintain a certain foliage effect, attention must be paid to the following issues.

First, place. After the foliage plants enter the room, they should be placed in separate categories, and the plants in Xiyang should be placed on sunny windows; if they are plants with strong negative resistance, they should be placed in places without light, or receive a little scattered light. For those hanging pots and hanging pots, the foliage plants should also be frequently repositioned to allow them to receive some light properly. Some plants with colored markings, such as Golden Dragonstreet, Leafhoppers, etc., are cultivated under scattered light, which is conducive to the full expression of color. Too shading will make the color disappear or not bright, while the light is too strong, the leaves will turn yellow and lose their color. Pattern. Therefore, certain light should be given in winter and spring to facilitate plant growth and enhance stress resistance.

Second, regulate temperature. Most of the foliage plants are poor in cold resistance and high temperature resistance. After the arrival of winter, the temperature difference between day and night in the room should be as small as possible. The minimum indoor temperature at dawn should not be less than 5°C to 8°C and should reach about 20°C during the day. In addition, temperature differences occur in the same room, so plants with weak cold resistance can be placed high. The foliage plants placed on the windowsill are vulnerable to cold winds and should be blocked by thick curtains. For a small number of species that are extremely cold-tolerant, they can be kept warm for the winter by means of partial separation or small spaces and re-filming.

Third, adjust the humidity. In the winter, when houseplants have leaves withering and defoliation, the main reason is the humidity of the air. It is necessary to create a relatively moist environment. Every day, the leaves should be sprayed with water at a temperature of about 20°C to the leaves once or twice a day. It is advisable that the leaves do not drip. If conditions permit, it is best to sprinkle water around the pots to increase the air humidity in a small area. If the indoor air is particularly dry (heated indoors or heated by fire) and the blade is yellowed, it is necessary to adopt the full-bag plastic bag method as soon as possible to protect the severely damaged potted flowers and isolate them in a relatively humid and humid environment. Gradually restored to prevent further damage.

Fourth, suitable for water and fertilizer. The foliage plants generally have more leaves and are larger, and the water in the body volatilizes faster. However, due to the low temperature in winter, the growth basically stopped, the absorption function of the roots weakened, and the amount of water needed was also small. Therefore, as long as the leaves do not lose water, hairpins, basin soil is still dry as well, must not be too much water, too much easy to make the root rot, resulting in dead leaves. With the exception of a few flowers and trees that continue to grow in the winter and a lighter fertilizer and water application every month, most of the foliage plants and flowers should be completely stopped in order to prevent the normally dormant plants from germinating when the temporary temperature rises due to fertility, and the temperature will fall back. At the same time, it cannot normalize and consume the nutrients stored in the body, which in turn makes it unable to sleep normally, which reduces the ability to resist cold.
