Flowers are mainly divided into cold and cold. Most of the flowers from the tropical and subtropical regions will stop growing below 10°C and enter a dormancy period, otherwise they will easily freeze the leaves or be frozen to death. Such as the Araucaria, Zhu banana, pocket coconut, Milan, Clivia, jasmine, pineapple and other plants and directly in the basin of the color of cactus, etc., the room temperature should be maintained at about 3 °C -5 °C; and banyan, palm, rubber tree, Aloe vera, Schefflera trees, linden flowers, and arrows, the minimum room temperature should be 1°C-3°C; Chinese rose, azalea, sweet-scented osmanthus, and eucalyptus belong to cold-tolerant plants, even outdoors or on balconies, but Milan and Chrysanthemum Frosty plants, such as Pachira, must be moved indoors. Therefore, different flowers must be treated differently. The winter maintenance techniques of some common flowers are introduced as follows:
1, Chlorophytum
Chlorophytum is a warm, hi moist and semi-shady environment. It has strong adaptability, is more tolerant to drought, but not tolerant to cold, and has strict requirements for soil. Generally, it grows better in sandy soil with good drainage and loose fertility. Strict requirements on light, generally suitable for growth in moderate light conditions, also resistant to low light. The optimal temperature for growth is 15-25°C and the wintering temperature is 10°C. In winter, it will be moved to indoor and watered once every four days. The water should be poured. The best choice is to water at noon. The water temperature should be the same as the temperature when watering so that the roots can be frozen. In winter, it is advisable to keep the basin soil slightly moist, and the leaves should be cleaned frequently when placed indoors. Keeping the temperature at 15-20°C at room temperature, the spider plants can grow normally.
2, green radish
In areas of tropical rainforests originating in Central America and South America, sexual warm and humid semi-shaded conditions are suitable. The suitable temperature is 18°C-21°C during the day and 20°C-23°C in the evening. In winter, as long as the indoor temperature is not lower than 15°C, green radish can safely overwinter. If the temperature is lower than 10 °C, it is easy to cause defoliation and affect growth.
3, ivy
Ivy is more cold-resistant, less demanding on the sun, and enjoys the shade, no problem in winter indoors. The hot and humid climate in summer is very unfavorable to the growth of ivy.
4, Aloe vera
Aloe vera likes bright sunlight and high temperatures, but avoid exposure to strong light. The minimum temperature in winter can't be lower than 2°C, and it must be moved to the room in time. Although aloe vera likes water, it cannot be watered every day, and you can wait until the soil is dry before you water it.
5. Kale
The ability to withstand heavy snowfall and a low temperature of minus 11 degrees Celsius add a hint of greenness to the cold winter and introduce it to the north, which is a good open field flower in the winter.
6, jasmine
Room temperature above 25 °C, plus more applied to potash-based flowering fertilizer, you can reduce the foliage and promote flowering.
7, Haishu
The most suitable growth temperature is 15-22 °C, hi warm, humid and semi-negative environment, avoid high temperature and water damage; under short days can be earlier flowering period, and short winter sunshine just to meet their needs.
8, anthurium
The optimum growth temperature for potted Anthurium was 20-30°C and the minimum temperature was 14°C. Air humidity is the key to the success of Anthurium cultivation. Therefore, leaf spray should be performed multiple times throughout the year so that flowering can continue.
9, Du Fu
Winter azaleas usually enter dormancy, but if the balcony or room temperature reaches a certain level, for example between 15-25°C. Even if it is summer, it will end its dormancy and continue to blossom. In winter, rhododendrons do not need much water, and they are usually watered once every 4 to 5 days.
Phalaenopsis
In the flowering period, the indoor temperature should be controlled at 15-18°C and relative humidity 60%-70%. Do not place flowers on the radiator or near the heater. Do not let in direct sunlight. The water temperature of the watering is preferably close to the room temperature, and the sprayer blade can be used to increase the humidity frequently. During the growing season, special fertilizer for orchids can be used for 2000 to 3000 times, and it is not necessary to fertilize at flowering stage.
11. Lilies
Most breeds prefer a cool, moist half-negative environment that is more tolerant of cold and will not die cold in winter even if the temperature drops to 3-5°C. Appropriate growth temperature of 12-18 °C, 12-25 °C can normal flowering.
12, Geranium
Geranium likes sunshine, good warmth, a little drought, and water. Day-to-day management should be pruned topping. After flowering, we must cut off residual flowers to promote the growth of new flower buds. Repeated topping can promote its increase in branches and pregnant buds. Room temperature at room temperature, as long as the temperature reaches 15 °C above, no less than 8 °C at night, see the dry water, you can be happy throughout the winter. About 10 °C can maintain the evergreen state.
13. Tie Lan
Blue-violet flowers can be from autumn until the following spring. Loose, well-drained leafless or peat soil is required to keep the basin wet and light, and the winter temperature is not lower than 10°C.
