The leaves are beautiful in color and full of yellow flowers when they are in full bloom. They are usually planted and applied in hedges, walls, watersides, slopes and forest edges of gardens in southern cities. It can also be decorated with lawns and rockeries, planted as flower diameters and hedges, planted in clusters, or planted in rows with Spiraea and Jin Fenghua. Tang Di is a deciduous shrub with an altitude of1~ 3m. Branchlets are slender and green, glabrous, usually arched and angular. Simple leaves alternate, triangular, ovoid or ovoid, with serrated edges.
Flowers are solitary at the top of the lateral branches of the year, with a diameter of 2.5 ~ 6 cm and yellow. Sepals ovoid-elliptic, glabrous, fruit persistent. The flowering period is from April to June. Tang Di has strong adaptability, likes mild and warm climate, and has a little tolerance for damp. The requirements for soil are not strict, and sandy soil with good drainage is better. The cold tolerance is poor, and the cultivation in the open field in the north needs to be cultivated in winter to prevent the dead bamboo shoots. Tang Di's roots and tillers germinate vigorously, and green shoots are clustered from the surface of the earth, showing a shrub shape.
Generally, it doesn't need special shaping, let it grow naturally, but it should be updated in time. Because the flower buds are formed in the new shoots, after the new branches are born, it is only appropriate to prune the branches before flowering, and not to cut them short or pick the heart, otherwise the flower buds will be cut off. However, in order to promote more new branches and more flowers, old branches, over-dense branches and residual flower branches should be pruned after flowering or at the end of autumn. If dead branches are found, they can be cut off at any time to avoid spreading. stop
When sleeping, cut off dead branches, too dense branches, hard white old branches and other branches from the base. Tang Di is developing rapidly with dense clusters. Cut 1 time again every 2 ~ 3 years to promote more new branches and more flower buds. Plant regeneration is carried out every 5 ~ 10 years 1 time. Leave a section 10 ~ 15 cm above the ground after flowering, and cut off the rest. Tang Di is often used as a flower hedge in gardens, which can form a golden flower barrier during flowering. At this time, it is not necessary to prune every year, and then carry out thinning and updating when too many old branches hinder the development of new branches.
