Chaenomeles japonica likes full sunlight and is tolerant to semi-shade. It does not grow well in saline-alkaline soil and clay soil.
Chaenomeles japonica likes to be wet but is afraid of waterlogging and rot.
The propagation of Chaenomeles japonica was mainly carried out by cutting in spring and autumn. The strong branches with a length of about 10 cm were cut and inserted in plain sand soil, watered to keep wet, placed in the shade, rooting in about 30 days, and then transplanted in the next spring. Grafting is also commonly used for reproduction, with cutting occurring in the spring and dependency occurring between April and July. Chaenomeles japonica can also be propagated by dividing plants, which can be carried out in spring and autumn and is easy to survive.
Chaenomeles japonica is easy to grow aphids. It can be sprayed by soaking tobacco leaves in water (available overnight) and avoided by dioate, otherwise it will cause fallen leaves. It can be destroyed by hand when domestic cultivation is small.

Flowers double, 3.5 -- 4.5cm in diameter; Petals 20 to 25, circular spoon-shaped; Flowers pale green at first, greenish-white or slightly yellowish at full bloom (RHS-CC 2D ~ 4D). According to the study, 'emerald stone' (Wang Jiaxiang,1998) and 'Yinshengshou' (Zhao Hongxia,2003) are the same variety. The former was published in 1998 and the latter in 2003. According to I.C.N.C.P., the earlier 'emerald stone' is chosen as the correct name.
Flowers double, 3 -- 5cm in diam. Petals 15 to 20, circular, spoon-shaped, curled upward, with short claws; Corolla red with orange (RHS-CC 34A -- 34B).
(' Hong Baoshi ') -- Different name: 'Longevity Crown'

The former was published in 1998 and the latter in 2003. According to I.C.N.C.P., the earlier 'Ruby' is chosen as the correct name.
Flowers double, 5 -- 7cm in diam.Petals 28 to 35;Corolla red or orange-tinged (RHS-CC 41C).When the author published the variety, he proposed two names' Dafui Fugui 'and' World One '(Wang Jiaxiang, 1998), of which' Dafui Fugui 'has been widely used, according to the I.C.N.C.P.Stipulates that 'World One' is used as a synonym.
