Autumn Maintenance of Chinese Roses
The editor will tell you about the knowledge of roses, the autumn maintenance of Chinese roses, and the detailed answers for you next.
Among the four seasons, spring, summer, and autumn are the main growing seasons for Chinese roses, followed by the fastest growth rate in early autumn, and the early autumn season is the key season for strengthening maintenance and pest and disease control.
After enduring the torments of high temperatures and exposure to the sun, entering the cool and pleasant autumn provides a good climatic environment for the growth of Chinese roses; however, it is also necessary to strengthen the maintenance of Chinese roses during this period. Pay attention to the residual pests and diseases brought to the roses by the later stage of summer. If prevention and control are not taken, combined with the short high-temperature hot weather in early autumn, pests and diseases will recur. The main disease is black spot. Black spot is a major enemy to the growth of Chinese roses, causing the flowers and leaves of the roses to fall off. We can take the following measures to prevent the recurrence of the disease:
One, control the frequency of watering or sprinkling, and timely loosen the soil to remove some soil moisture.
Two, mix and use decomposed manure and chemical fertilizers such as urea and compound fertilizers. Strengthening maintenance at the right time is an important part of autumn maintenance for Chinese roses. This maintenance creates conditions for the timely flowering of roses and the safe overwintering of annual and perennial plants.
In addition, the prevention and control of pest insects in autumn is also very important. The main pests of Chinese roses in autumn are aphids, which have a short breeding cycle, strong reproductive capacity, large numbers, and strong attachment to the plants. There are many drugs currently available, such as mesotrione, brochlorophenol, and pyrethroid emulsions, that can effectively control pests.
After the early autumn, the main stem of the Chinese rose accumulates enough nutrients to overwinter. By late autumn, the Chinese rose can be pruned heavily, that is, most of the branches of the Chinese rose are cut off, leaving only the parts within 20 centimeters above the ground. This not only helps the Chinese rose to overwinter but also appropriately prevents the Chinese rose from being affected by pests and diseases the following year.
