Photinia, scientific name Photinia serrulata Lindl., English name Photinia, also known as Qiannianhong, Shanngumuwu (Fanbone Wood), and other names. An evergreen shrub or small tree of the Rosaceae family and the genus Photinia, native to China. The flowering period is April to May, and the fruiting period is October. It has a rounded crown and dense foliage; the young leaves are red, the flowers are white and densely borne, and the winter fruits are red and strikingly showy. It is a commonly cultivated tree species; its wood is hard and dense and can be used to make wheels and tool handles; its leaves and roots are used medicinally as a tonic and diuretic, with effects such as sedation and fever reduction; it can also be used as a botanical pesticide to control aphids and has an inhibitory effect on the germination of potato blight spores; the seeds are pressed for oil used to make paint, soap, or lubricating oil; it can serve as rootstock for loquat. Loquat grafted onto photinia has a long lifespan, tolerates poor soil, and grows vigorously.


How is photinia planted?

Photinia has low requirements for soil, but because its root system is relatively deep, it is better suited to loose, fertile sandy soil. Photinia is generally propagated by sowing, and cuttings and layering are also often used. Soil: Photinia is not strict about soil and is suitable for cultivation in fertile, well-drained sandy loam; note that it grows poorly in clay.

Light and temperature: Photinia likes light, tolerates slight shade, is relatively cold-hardy, and can withstand low temperatures of -15°C. Water and fertilizer: Photinia prefers moisture, so keep the soil moist regularly, but be careful to avoid overwatering, otherwise waterlogging can easily cause the plant's roots to rot. Follow the principle of light but frequent applications; in spring, fertilize about once every 15 days, and in summer and autumn apply a compound fertilizer about once every 15 days.

Cultivation and management

During the recovery period after planting, special attention must be paid to water management. If there are consecutive sunny days, water once 3-4 days after transplanting, and thereafter water about once every 10 days; if there are consecutive rainy days, drain promptly. After about 15 days, once the seedlings have passed the recovery period, they can be fertilized. In spring, apply urea once every half month at about 5 kg/mu; in summer and autumn, apply a compound fertilizer once every half month at 5 kg/mu; in winter, apply decomposed organic fertilizer once at 1500 kg/mu, preferably by trenching and burying. Fertilization should follow the principle of light but frequent applications, and the amount used at one time must not be too large, so as to avoid damaging the roots and burning the seedlings. Weed and loosen the soil promptly in normal times to prevent soil compaction.

Pest and disease control

Photinia has strong resistance, and no devastating pests or diseases have been found. However, if management is improper or the nursery environment is poor, gray mold, leaf spot, or damage by scale insects may occur. Gray mold can be prevented by spraying with a 50% carbendazim 1000-fold solution, and during the disease period it can be controlled by spraying with a 50% zineb 800-fold solution. Leaf spot can be controlled with a 50% carbendazim 300 to 400-fold solution or a thiophanate 300-400-fold solution. Scale insects can be sprayed with a dimethoate emulsion 200-fold solution or a 800 to 1000-fold spray.
