strong shade tolerance. Suitable for all types of medium-fertile soil. It is resistant to poor soil and has certain tolerance to salt-alkali and drought. Not resistant to moisture. Photinia has a fast growth rate, strong budding resistance, pruning resistance and easy transplantation. Photinia with red leaves
d= After entering the winter dormancy period, the following four measures should be taken for the maintenance of Photinia with red leaves in garden engineering applications.
d=. Antifreeze soil damages roots. The frozen soil layer can easily cause physiological drought and death of plants. For Photinia that is planted in areas with frozen soil in winter, especially those planted in the current year, soil antifreeze should be used to protect the root system. Surface covering is usually carried out half a month before the frozen soil layer is produced to maintain soil temperature.
d=. Pest and disease control mainly involves cleaning up diseased branches, insect branches, dead branches and other overwintering hosts of diseases and insect pests to reduce pests and diseases in the coming year.
d= . Application of winter fertilizer In order to ensure the strong growth and ornamental effect of the spring shoots in the coming year, winter fertilizer should be applied once in the current year to the middle of the next year in combination with loosening the soil. The appropriate dosage of fertilizer is compound fertilizer with higher nitrogen content, which is about grams per square meter.
d=. The germination period of pruned red-leaf Photinia usually begins before the end of the month. In order to improve the consistency and tightness of new shoot germination in spring and achieve the best viewing effect, light pruning should be carried out in different months according to the use requirements of different products. Since Photinia is widely used in a wide geographical range, the corresponding winter maintenance time and measures should be carried out according to the actual local conditions in order to achieve the best results.
