Spring pruning can be carried out in February in warm areas in the south, and it can be postponed to March in cold areas in central and northern China. At this time, the temperature gradually rises, and jasmine begins to grow again. We should change pots, soil, pruning and shaping in time to promote it to enter the peak season of the new season.
Pruning in southern spring can be a little lighter, because the temperature and light are suitable, and jasmine flowers can bloom early. Pruning in the northern region can be heavier, pruning the overwintering branches and weak side branches together to promote the germination of more new branches and make the plant shape fuller.
Jasmine with proper cultivation and management has four flowering periods every year, which can last from May to around 10. Jasmine flowers are all on the branches of new branches. The old branches that have blossomed not only affect the appreciation, but also consume nutrients and affect the flowering of new branches.
Therefore, after each flowering, the residual flowers and two pairs of leaves should be trimmed in time to promote the germination of more new branches and lateral branches, so that the whole plant type looks fuller.
Before entering the room in winter, jasmine will consume a lot of nutrients if it has too many branches and leaves. At this time, because of its weak root system, its growth is extremely slow. If the dead branches and too many weak branches are not cut off, it is easy to survive the winter because of insufficient nutrient supply.
Pruning before overwintering is determined by the cultivation environment. If the indoor culture temperature is high, it will be simpler and thicker. When the temperature is around 10℃, jasmine will enter the dormant period, and rely on the nutrients stored in the main branches to overwinter, and try to cut them lightly to prevent overwintering failure.
Matters needing attention in jasmine cultivation
1, pay attention to the light
The maintenance of jasmine should pay attention to the light. Jasmine likes to grow in a semi-cool environment. It is best to keep jasmine in an environment with sufficient scattered light every day, which is most conducive to its growth and flowering. Jasmine should not be kept in the shade for a long time, nor should it be exposed to the sun, otherwise it will dry up easily.
Step 2 pay attention to the temperature
Care should also be paid to the temperature of jasmine, because it likes warmth. In summer, it is necessary to maintain jasmine in a cool and ventilated environment. In winter, it is necessary to move jasmine to a warm place indoors for maintenance, and the temperature should not be lower than 3℃, otherwise the branches and leaves of jasmine will be easily frozen.
Step 3 pay attention to watering
Jasmine likes humidity and is not drought-tolerant, so it needs careful watering and maintenance. It needs to keep the soil slightly moist during growth. When the climate is dry, it is necessary to spray water around frequently to increase the air humidity, but it is not allowed to accumulate water in the soil, otherwise the jasmine will rot its roots.
4. Pay attention to fertilization
When maintaining jasmine, we should also pay attention to fertilization. In its flowering period, liquid fertilizer containing more phosphorus should be applied every 2-3 days, and some potassium dihydrogen phosphate foliar fertilizer can also be sprayed. Pay attention to the principle of applying thin fertilizer frequently, and don't apply thick fertilizer to jasmine.
