First, trim the messy branches and leaves.
With the increase of temperature, many bonsai of winter jasmine raised at home have gradually ended their flowering period and started to grow branches and leaves. At this time, they can start trimming and shaping.
The branches of Yingchun have strong germination ability, and a large number of branches will grow every year. In order to maintain a good plant shape, it is generally necessary to prune it many times. Pruning after flowering is mainly to cut off dead branches, diseased branches and too messy and dense branches. Proper pruning of redundant branches can not only increase the permeability between branches and leaves, but also reduce nutrient consumption and keep the plant shape symmetrical and beautiful.
The cuttings of winter jasmine branches are easy to survive. Pruned branches can be simply pruned, cut into moist pot soil, and often watered to keep the soil moist, and they can take root and sprout after a while.
Second, replace the new basin soil.
Generally speaking, potted plants in spring need to be turned over to change the soil, otherwise the roots will be full of flowerpots, and the nutrients in the pots will become scarce, which is no longer suitable for the growth and development of plants. It is best to turn over the pots and change the soil after flowering in spring.
When changing pots, trim messy fibrous roots, old roots and dead roots. For rotten roots, use potassium permanganate and other solutions for disinfection before planting pots.
When preparing to cultivate soil during the Spring Festival, you can add more humus soil, organic fertilizer and cinder. Increase soil nutrients and drainage permeability, and reduce water accumulation caused by excessive watering.
Third, supplement nutrition regularly.
After pruning in spring, you can start supplementing nutrition in a week or so to make the plants grow vigorously. In spring, nitrogen fertilizer is the main fertilizer, and some decomposed bean cake fertilizer, sheep manure and chicken manure can be applied, or more fermented organic fertilizer water can be poured at ordinary times, which can also promote plant growth.
After entering summer, if the temperature is too high, fertilization should be temporarily stopped until it is cool in autumn, and then nutrition should be supplemented to facilitate the formation of flower buds.
Fourth, prevent and control diseases in advance.
After the weather gets warmer, the probability of pests and diseases in the Spring Festival is also increasing. Preventive measures should be taken in advance to increase the ventilation of the environment and avoid the basin soil from being too wet.
Brown spot and brown spot often occur in spring, and brown spots appear on the leaves of infected plants. Spraying 70% chlorothalonil wettable powder 1000 times solution and other fungicides at the initial stage of the disease.
Botrytis cinerea is also one of the common diseases of winter jasmine, which can infect tender stems and leaves, and seriously cause the whole plant to wither and die. After the onset of the disease, the leaves should be removed in time, and 50% prochloraz or 50% chlorpheniramine wettable powder 1500 times solution should be sprayed at the initial stage for control.
Spring is the vigorous growth period of the Spring Festival. At this time, you can prune branches and leaves, change pots and soil, supplement nutrition and promote the vigorous growth of plants. You can also use this time to cultivate new plants in flowerpots. These plants have a high survival rate.
