The color performance of Jiaodong lance at sub zero temperatures can be described from the following aspects: 1. Leaf color
At extreme low temperatures, such as minus 20 degrees Celsius, the leaves of the Jiaodong Euonymus japonicus may suffer from freezing damage, resulting in yellowing or withering. However, in general sub zero low temperature environments, and if the Jiaodong lance is well maintained, its leaf color may not undergo significant changes and can still remain green. Under the condition of large temperature difference in autumn, the leaves of Jiaodong lance may also turn red or purple red, adding a bright color to winter. 2、 Flowers and Fruit Colors
The flowering period of Jiaodong Euonymus japonicus is from August to September, during which its flowers are white green and the inflorescence is dispersed. The fruiting period is in October, and the fruit is a pink capsule with a slightly spherical shape. At sub zero temperatures, as flowers and fruits have already withered or matured, their color will not undergo significant changes due to low temperatures. However, if the fruit is still on the tree and not damaged by freezing, its pink color may remain for some time. 3、 Overall color representation
Jiaodong Euonymus japonicus, as a semi evergreen shrub, has good cold resistance and soil adaptability. In sub zero temperature environments, the overall color performance may vary due to individual differences, maintenance conditions, and specific environmental temperatures. But generally speaking, as long as properly maintained, the Jiaodong Euonymus can still maintain its unique green or red leaf beauty (in autumn), adding vitality to winter. 4、 Maintenance suggestions
In order to maintain better color performance of Jiaodong lance in sub zero temperature environments, the following maintenance measures can be taken:
1. Choose a suitable growth environment: Choose a well lit, well ventilated, and temperature sensitive growth environment for the Jiaodong Euonymus japonicus, which is conducive to the synthesis and decomposition of pigments in its leaves, forming a beautiful red leaf landscape (in autumn). At the same time, it also helps to improve its cold resistance.
2. Reasonable watering and fertilization: During the vigorous growth period, the amount of watering and fertilization should be appropriately increased to meet its growth needs. But in low temperature seasons such as winter, watering and fertilization frequency should be reduced to avoid problems such as root rot.
3. Regular pruning: Regularly pruning the branches and leaves of Jiaodong lance helps maintain its beauty and promote the growth of new leaves. During the pruning process, attention should be paid to cutting off unhealthy parts such as diseased branches and dead leaves to maintain the healthy growth of the plant.
The color expression of Jiaodong lance at sub zero temperatures may vary due to various factors. However, as long as it is properly maintained, it can still showcase its unique charm and color.
