Although pruning can promote branching and blossom more, it is also necessary to ensure the beautiful shape of the plant when pruning, which can be carried out in June ~ July after flowering. Cut off diseased branches, clustered branches and twigs, and the cut branches can be used as cuttings to cultivate new potted Rosa davurica fruit.
When the seedlings grow to 10 cm, the tops of branches can be cut off to promote the development of lateral branches; After that, when the lateral branches grow to a certain height, the top of the branches will be cut off, and the lateral branches will be lifted again to form a basic backbone branch frame. When you have 4-5 branches, you should design a long-term cultivation goal in advance, or tie it into a ball, a flower screen, or a flower basket, and then erect a pole bracket according to the set goal, and properly pull, bend and tie the branches to make them develop directionally.
Rosa davurica (Euphorbia. Desmoulins) belongs to Euphorbiaceae Euphorbia. It is a thorny erect or slightly climbing shrub. Strong sex, like warm and dry climate, suitable growth humidity is 18-25℃. If the indoor temperature can be kept above 15℃ in winter, flowers will bloom all winter. If the humidity is too low, all the leaves will fall off and go into a dormant state. Adequate sunshine is needed in flowering period, and topdressing, organic liquid fertilizer or compound fertilizer can be used once every half month. Suitable for the growth of loose sandy soil.
At the top of each branch, a slender stem grows next to the leaves. At first, two or four blue-yellow buds smaller than mung beans grew on each slender stem, and the buds gradually grew up and spread out into two petals.
