① 70% waste soil and 30% river sand are mixed.
② 60% of dry river mud and 40% of honeycomb cinder are mixed.
③ 70% vegetable garden soil, 20% honeycomb cinder and 10% river sand are mixed.
Time of potting: after falling leaves in early winter or before sprouting in early spring.
Because the potted rose is controlled by the limited potted soil, the requirement of fertilizer and water is strict.
① generally, the first choice is convenient and sanitary compound fertilizer, because the compound fertilizer has various elements, and the nitrogen, phosphorus and potassium are well matched. Each plant is applied with about 20 grams (not too much), and the basin soil around the basin edge is turned over with an iron tool about 10 cm deep, and then the fertilizer is applied, and then the soil is covered.
② watering is one of the basic work of flower cultivation, but it is also the reason why the plants are easy to die. Watering depends on pot soil. Once it's dry, it's necessary to water it once. If it's too wet, it's easy to cause rotten roots. Every other year, we need to change the basin soil. When changing the basin, we need to cut off the surrounding roots at the bottom of the basin, so as to make the flowers more, bigger and more colorful.
Usually, pruning is not necessary. The old plant can be pruned to dense branches, withered branches and disease and insect branches. Rose flowers, with the opening and failure with the pick, after picking again, or only once flowers.
Scientific weeding, because the seedlings are small, weeds are easy to grow, so we should do a good job of weeding in real time, so as not to hurt the seedlings and grass. Keep the earth loose. The fertilizer is mainly organic fertilizer, which is applied four times a year. Before and after the Bright Festival, the first time is to pour livestock manure water, which is called germinating fertilizer, and water in real time. In late April, the second time is to apply human and livestock manure water before the buds are pregnant or flowers are picked, so as to make the flower buds more and full. In May, the biological organic fertilizer is applied, and the winter fertilizer is applied at the end of autumn and the beginning of winter, so as to ensure the seedlings to survive the winter peacefully. After flowering in June and dormancy period in winter, old branches, disease and insect branches and delicate branches were cut off to produce new branches. In each period of field management, the prevention and control of diseases and pests should be carried out carefully.
