How to choose flowers according to indoor temperature?
Air temperature is an important
condition affecting the growth of flowers. The suitable air temperature for the growth of most flowers is between 10 and 25°C. Too high an air temperature will cause the proteins in the flowers to coagulate and denature, destroy the chloroplasts, and increase nutrient consumption. Too low an air temperature will reduce the vitality of the flower cells' protoplasm and weaken the roots' absorption capacity, mildly injuring the flowers and severely causing death.
To avoid these phenomena, we can choose suitable flowers and plants to grow according to the indoor temperature. Especially in winter, if you do not understand the overwintering temperature of flowers, casually bringing a certain kind of flower into the house may well make it unable to overwinter safely. Chrysanthemum, Japanese evergreen (Rohdea japonica), peony, plum blossom, pomegranate, crabapple and others belong to cold-tolerant flowers; their places of origin are in temperate and frigid zones, and they can generally withstand a short period of low temperature of -3 to 5°C, can grow at 5 to 10°C, and grow luxuriantly at 10 to 25°C. Broadleaf lady palm (Rhapis excelsa), sago palm (Cycas revoluta), Chinese fan palm (Livistona chinensis) and others are warmth-loving
flowers; they generally grow luxuriantly above 25°C, show slow growth below 10°C, and enter dormancy below 5°C. White orchid (Michelia alba), Chinese hibiscus (Hibiscus rosa-sinensis), jasmine and others need 6 to 10°C to overwinter safely. Cyclamen, fuchsia, geranium and others cannot go below 10°C, while for plumeria, poinsettia, Impatiens walleriana, and the succulent flowers such as candle plant (Senecio articulatus), epiphyllum, orchid cactus (Epiphyllum), and agave, the room temperature cannot be below 12°C.
Expert comment: Once you have chosen the right kind of flower, you will not need to waste too much time and energy on the temperature problem in daily life. But issues such as the environment, light, ventilation, and watering still need to be treated carefully. Grow flowers according to the different growth characteristics of the plants, as well as the orientation of the room and the duration of light.
Expert suggestion: Choose according to indoor temperature. Generally speaking, in areas where there is no heating facility indoors in winter, the indoor temperature can only be maintained at around 0 to 5°C. For such a room, you can choose some flowers that are slightly tolerant of low temperatures, such as: clematis, geranium, rubber tree (Ficus elastica), broadleaf lady palm, ivy, asparagus fern, giant taro (Alocasia), Schefflera arboricola, Norfolk Island pine (Araucaria heterophylla) and others; these flowers and plants are slightly cold-tolerant and can grow well at such temperatures.
If the indoor temperature can be maintained at around 8°C, then in addition to the above flowers, you can also grow foliage plants such as money tree (Pachira aquatica), clivia, pothos, bromeliad, and Dracaena fragrans. If the room temperature can be maintained above 10°C, the range of choices for a household is even greater. Anthurium, cyclamen, crabapple, bird's nest fern (Asplenium nidus), bougainvillea, Japanese evergreen (Rohdea japonica) and others can all be chosen for growing. A tip for you: you can place the flowers on a sunny windowsill or balcony to cultivate them, so as to ensure sufficient light. In addition, pay attention to watering; the potting soil must not be too dry or too wet. In a low-temperature environment, potted flowers grow slowly, and their demand for nutrients gradually decreases; at this time, apply a small amount of fertilizer, just enough to maintain nutrition, and by no means water with heavy fertilizer and heavy water, so as to avoid root rot and disease.
