Winter Care for foliage plants
Do you know these? Common knowledge about flower care, winter care for foliage plants, the following is a detailed introduction.
To keep foliage plants from tropical and subtropical regions green and vigorous in winter, the following points should be followed:
I. Keep warm and prevent freezing
Different foliage plants have different minimum temperatures for overwintering, and there is a large difference. The cold resistance of the same type of different varieties is also significantly different. Therefore, it is necessary to carry out separate and classified overwintering in the room according to the region, plant type, and variety. Keeping warm and preventing freezing is an important part of the care work for foliage plants to survive the winter safely. According to the different temperature requirements of foliage plants for overwintering, the author believes that they can be divided into four categories, each taking different measures for keeping warm and preventing freezing.
Category 1: Foliage plants that cannot be below 5 degrees Celsius in winter, such as Asparagus, Aspidistra elatior, Cyperus alternifolius, Fatsia japonica, Soleirolia soleirolii, Alocasia, Pilea, and Phoenix roebelenii. These plants have certain cold resistance and can safely overwinter under general cold-proof facilities, or can be placed in a single-layer plastic greenhouse or general greenhouse.

Category 2: Foliage plants that cannot be below 8 degrees Celsius, such as Crassula, Saxifraga stolonifera, Dracaena, Caryota mitis, Bambusa ventricosa, and Nephrolepis exaltata. They have certain cold resistance but should have an additional layer of plastic film in the greenhouse or room during the coldest periods.
Category 3: Foliage plants that cannot be below 10 degrees Celsius, such as Asparagus setaceus, Chlorophytum comosum, Peperomia, Caladium, Thalia dealbata, Epipremnum aureum, Dracaena fragrans, Araucaria heterophylla, and Dracaena sanderiana. They should be placed in a double-layer plastic greenhouse or a greenhouse with an additional layer of plastic film as soon as winter begins.
Category 4: Foliage plants that cannot be below 15 degrees Celsius, such as Chrysalidocarpus lutescens, Codiaeum variegatum, Fittonia, Pachira aquatica, and Nephrolepis exaltata 'Bostoniensis'. They have higher requirements for overwintering temperature and are best placed in a greenhouse with heating equipment. If there are no heating conditions, they can be placed in a double-layer plastic greenhouse. In southern areas, an additional layer of plastic film should be placed on top of the foliage plants from 3 pm to 9 am the next day.
II. Appropriate watering
After entering winter, the growth of foliage plants basically stops, some plants enter a dormant stage, and their water absorption capacity is greatly reduced. Watering should not be excessive. Water should be fully watered before entering the greenhouse or room, and during the greenhouse period, the pot soil should be kept slightly dry to help the foliage plants overwinter. When the pot soil is too dry, water should be added at 11 am on sunny and warm days, and be careful not to add too much water or water in the morning or evening. The water temperature should be similar to the room temperature, and the temperature difference should not be too large. Foliage plants generally water once every half a month in winter, and too much water can easily cause root rot. In the dry air of northern winters, plants like Calathea need to be sprayed with cold water on the leaves during the day to increase indoor humidity and maintain their beautiful leaf color; during the overwintering period of Alocasia, spraying warm water every 3-5 days can keep the leaves dark green; Aglaonema, in winter, needs to be sprayed 2-3 times with warm water to clean the leaf surface dust, increase indoor air humidity, and make the patch colors bright and strong.
III. Ventilation and breathing
Foliage plants need a certain amount of air humidity in the greenhouse or room during the winter, but it should not be too high. Therefore, it is necessary to open the doors and windows on sunny and warm days to adjust the humidity of the air, especially the higher humidity in plastic greenhouses, and more attention should be paid to ventilation. Ventilation is generally suitable from 9 am to 3 pm. Light is also very important for the cultivation of foliage plants in winter. Winter sunlight is oblique, and the light intensity is half of that in summer. For some large-sized sun-loving woody foliage plants, they should be placed on the outskirts of the greenhouse, such as Dracaena fragrans, Caryota mitis, Ficus elastica, and Codiaeum variegatum. Under sufficient light, foliage plants can also become thin and yellow in winter. For some small-sized herbaceous foliage plants, they should be placed at a high place, such as Asparagus, Coleus, and shade-tolerant and semi-shade foliage plants can be placed in the middle, such as Epipremnum aureum, Rhapis excelsa, Chrysalidocarpus lutescens, Monstera deliciosa, Asparagus setaceus, Pilea, Alocasia, and Cordyline terminalis. These plants also need a certain amount of light in winter. Due to the high humidity in the greenhouse, if they often lack light, they will get diseases and pests, so during the overwintering period, it is necessary to "turn the greenhouse" to change the location to ensure the safe wintering of the foliage plants.
