Rosa chinensis is a plant that likes light very much. It needs a lot of light. We suggest full-time light, but some varieties. The demand for light is not very strong, but it can't be without light. At least rosa chinensis can grow well in more than half a day. Better light can be conducive to plant photosynthesis, promote root growth, flowering and plant opening, and promote plant sprouting.
For the roses of small seedlings, medium seedlings and large seedlings, we suggest that they should be taken all day. Some varieties need proper shade in summer, and try to give better light. Roses are not afraid of sun exposure, so you don't need shade if you don't need to see flowers in hot weather in summer. Of course, for some Rosa chinensis varieties, because the flowers are not sun resistant, we can provide an appropriate amount of shade, which can increase the viewing cycle of flowers.
Rosa Chinensis likes moist soil and is afraid of drought or ponding. Therefore, it must be ensured that the soil is loose, the drainage is good, and there is a certain role of water and fertilizer conservation. The selection of Rosa chinensis flowerpot does not need to be very fancy. It can be a permeable and breathable ordinary mud basin. Our new mud basin can be soaked with water before use.
Rosa chinesis repotting is divided into two situations. One is to buy seedlings from yellow soil, which should be paid attention to when changing pots, and the other is to plant them in nutritious soil. Rosa chinesis repotting is much simpler. For roses planted in yellow soil, remember to wash roots and change pots without mud bumps, After planting, the drying speed of mud pimples is very slow, and after the yellow mud is completely dry, you go to the side and fill it with nutrient soil. If you water, the yellow mud pimples can't absorb water. The nutrient soil has been completely wet, which will cause the internal dry and external wet situation, which is absolutely bad. Therefore, you must thoroughly wash the roots and change the basin. We can soak the yellow mud in water. After soaking the yellow mud, we can plant it with new nutrient soil. After planting, we must water it, and we must pour some rooting liquid and carbendazim into it. If the branches are too long, trim them properly, and then put them in a place with good ventilation and a little scattered light. Spray water on them every morning and evening to moisturize them, so that the leaves can absorb some water. In this way, Rosa chinensis can recover completely after last week.
If before growing potted Rosa chinensis Jacq, you first need to prepare a clay pot of appropriate size, with drainage holes at the bottom, and usually use garden soil, garbage soil, and hull ash according to 5:3:2. Mix the soil with the ratio of, and change the pot every two years, and the potting container needs to be gradually enlarged.
Generally, when we grow and care for Rosa chinensis Jacq, it is best to maintain the temperature at 18-20℃. Usually, it needs to be placed in the sun for curing, but in summer, it needs to be watered and cooled. In winter, rosa chinensis jacq not only needs enough light, and the temperature must be controlled above 5°C to make more flowers bloom during the flowering period.
Generally, Rosa chinensis Jacq grows vigorously in spring and autumn. When we grow and care for Rosa chinensis Jacq, we need to water it every 2 to 4 days. We need to irrigate the soil every time. When the climate gradually warms up, we can also increase the watering amount. To do a good job of drainage, generally apply organic fertilizer every half a month during the seedling period, and apply nitrogen fertilizer and a small amount of phosphorus and potassium fertilizer every 10 days during the growth period.
When we grow and care for Rosa chinensis Jacq, Rosa chinensis Jacq needs to be properly pruned every year. When new branches of Rosa chinensis Jacq grow to 15-20cm each spring, they need to be pruned to 3～5cm, and then useless branches are cut off. This can resist the growth of Rosa chinensis Jacq, promotes the germination of side buds and makes them bloom beautiful flowers, which increases the ornamental value of Rosa chinensis Jacq.
Rosa chinensis Jacq needs to be pruned and shaped in spring and autumn every year. When we grow and care for Rosa chinensis, after pruning, it must be sprayed with medicine. You can select strong branches from the branches left after pruning, and then dispose of the upper leaves of the branches, and then insert them into suitable ones. In the growing soil, it can be carefully maintained under astigmatism.
After the cold winter, the temperature began to rise gradually. At this time, Rosa chinensis can be cultivated. When cultivating Rosa chinensis, we must give it fluffy and well-drained soil for growth, and we should also put it in a place with plenty of light for maintenance.
Rosa Chinensis will continue to open from April to November every year. Its flowers are rich in color, including red, white and yellow, which has high ornamental value. When breeding Rosa chinensis at the flowering stage, it is necessary to place it in a bright place to promote the light cooperation of plants. After the flowering stage of Rosa chinensis, We will cut off the withered flowers and yellow branches and leaves.
Rosa chinensis is an ornamental flower with the characteristics of fragrant color and long flowering period. It is not only widely used in landscaping, but also very common in the layout of Flower beds and courtyards in gardens. It can also be appreciated as a bonsai in families. In addition, the production of cut flowers, flower baskets and bouquets is also a common use of Rosa chinensis. Rosa chinensis has the function of a greening environment. The characteristics of shrubs enable it to form a unique shape such as a continuous flower hedge, flower wall and flower screen.
Rosa chinensis is not only for people to enjoy in gardens and in various places, but also plays a dual role in greening the environment. The characteristics of shrubs enable them to form unique shapes such as continuous flower hedgerows, flower walls and flower screens. Growing in organs, schools, urban squares and residential areas, they can effectively purify the surrounding air and greatly reduce the noise pollution in nearby areas. They also have a good mitigation effect on the greenhouse effect in the City in summer.
