White flowers bloom in summer, dense and elegant, with a long flowering period. They should be planted on lawns, forest edges, roadsides and rock gardens, and can also be used as flower hedges.
Deutzia is a deciduous shrub with many branches and a height of 2.5 meters.

The leaves are opposite, ovate to ovate-lanceolate, with inconspicuous teeth on the leaf margin.
Erect panicle, tower-shaped, 5 ~ 12 cm long, with white flowers.
Capsule subglobose.
The flowering period is May-June.
Common varieties and cultivated varieties are narrow leaves, and the leaves are oval, oval or ovoid-lanceolate; Macular leaves are sparse with yellow and white spots; The white spot leaves are sparse and the leaves have white spots; The colorful leaves are sparse, the flowers are white, and there are reddish spots on the surface; Purple flowers are sparse, with rose-purple flowers on the surface, double; The bent petals are sparse, the flowers are small, and the petals are bent; White flowers, big shrubs, double flowers, pure white.
I like light, but I'm a little tolerant of shadows.
I like the warm climate, and I also have some cold and drought tolerance.
I like slightly acidic and neutral soil rich in humus.
Strong drainage, strong resistance to germination and pruning, but short life of branchlets.
Buds germinate in March-April, flower buds differentiate and flower in May-June. After flowering, it entered the secondary branching growth period, stopped growing before the fruit matured in June at 5438+1October, and fell leaves in late June at165438+1October.
Dredging takes the shape of a clump of shrubs.
Seedling growth is slow, the branches are cut off in the winter of the year of planting, and a few branches with good uprightness are kept after germination in the spring of the following year. In the winter of the following year, select lateral branches within 20-30 cm from the ground to expand the crown, remove too low lateral branches or budding branches, and core for many times to accelerate branching. After 3-4 years of cultivation, more than 5 skeleton branches can be applied to landscaping.
The maintenance and pruning of dredging are relatively extensive, and miscellaneous branches are combined with plastic surgery in winter, including thinning some old branches and growing new branches.
Long branches should adopt light, medium and short cuttings to grow in a balanced way, and at the same time use cuttings to control the growth direction of branches.
Because of the short life span of branchlets, the whole plant can be cut again for plant regeneration after 7-8 years, which can promote vigorous growth and more flowering.
