The maintenance of Chinese rose looks simple, but when it is really done, it is always light yellow. In severe cases, the roots will not bloom, especially when it is maintained on the balcony. Rose is prone to pests and diseases. Different regions and climates have different disease resistance. Common pests are stem bees, sawflies, leaf-cutting bees, moths, red spiders, scale insects, thrips and aphids, and common diseases are powdery mildew and gray mold.
Everyone asked by netizens said that roses are easy to raise. Why do my roses always have weak branches, fewer flowers and more pests and diseases? On this issue, about the maintenance of Chinese rose: how to raise Chinese rose so that it can flourish? Bian Xiao shared five aspects that should be paid attention to, namely potting soil, pruning, pests and diseases, water and fertilizer, and balcony.
1, basin soil
I think Chinese rose flowers don't have high requirements for pot soil, but it's better to use fertile, loose, breathable and permeable pot soil. I like to mix humus soil and pine needle soil with yellow sand, and the effect is good. Of course, there is now a special nutrient soil for Chinese rose. It is emphasized here that no matter how the soil is mixed, it is forbidden to use large pot seedlings, which has strong water retention and the roots are easy to suffocate and rot.
2. Water and fertilizer
Chinese rose likes to be fat and wet, so it is beneficial to keep the basin soil moist during the growing period when maintaining Chinese rose. There are flower buds in the rose until the flowering period. During this period, you can't water it too often, otherwise it will drop buds. Keeping the basin soil dry in winter is conducive to the smooth overwintering. As far as fertilizer nutrition is concerned, Chinese rose likes to supply fertilizer in large quantities.
When the rose is maintained, the base fertilizer should be supplemented in the early stage, and the thin fertilizer should be watered once every half month, and no fertilizer should be applied at flowering stage. After flowering, it is necessary to supplement fertilizer in time, plus foliar spraying at ordinary times, so that it is easy for Chinese rose to extract thick bamboo shoots and sprout new branches, with large flowers and bright colors. Of course, organic fertilizer is better, and excessive use of compound fertilizer can easily lead to hardening of basin soil, which is not conducive to the growth of rose. Of course, it would be much better to raise Chinese roses if they were planted in the ground.
prune
The flowering characteristics of Chinese rose flowers are flowering on new branches or new bamboo shoots, which should be pruned in time to promote new bamboo shoots, and pruned in winter to ensure the shape. Usually, when pruning, dead branches, tangzhi, branches with serious pests and diseases, weak branches and blind buds can be used for cutting. Rose has shrubs and vines, vines should be pulled, and shrubs should be piled.
4, pest control
Roses are vulnerable to pests and diseases. In the environment of high temperature and humidity, poor air permeability, stuffy and airtight, partial application of nitrogen fertilizer, too dense branches and insufficient space, pests and diseases are prone to occur. The plant protection policy of integrated pest management is prevention first. After spring every year, thiophanate methyl spray can be used to prevent diseases. When a big outbreak occurs, some good pesticides such as azoxystrobin and difenoconazole should be used for spray control, and the effect is very good.
5, balcony maintenance
If roses are planted in the ground, there will be fewer pests and diseases because of good ventilation, but most of them will be maintained on the indoor balcony. When roses are maintained on the balcony, we should pay attention to ventilation and reasonable illumination. When the temperature is high, we should reasonably wet spray to cool down, prune frequently, control bamboo shoots, apply fertilizer for a few times, and reasonably sparse flowers and buds according to the strength of branches, so as to achieve the effect of fertilizer on flowers and big leaves.
