It is best to choose the thick trunk for the stump of Jasminum nudiflorum, but most of them are not thick, and the upper and lower diameters are roughly the same, which lacks impression and can be adjusted by pinching branches. For the selected main branch, pinch the head several times to promote the growth of lateral buds, and then only the top lateral buds are left at a time. Over time, the main branch naturally twists and turns. The branches are soft, and if the flowers sway in the later stage, they can be made into bonsai with stones. Replacing stems with roots is to raise roots year by year, and we should not rush into it, otherwise too many capillary roots will lead to plant death.
After talking about cadre modeling, let's talk about branch modeling. There are two main forms. The first is to leave long branches, and the soft branches will droop naturally, just like the spring breeze blowing willows. When pruning, cut off the extra branches, otherwise the tertiary branches will be malnourished, and the length and density should be scattered and appropriate. The second is to leave short branches and imitate plum blossom pile type. Cut off the drooping parts of the branches, and all the branches are radial, which gives people another feeling compared with the drooping branches. Short branches are suitable for autumn and winter, which can protect the buds and prepare for the next spring.
The bonsai of winter jasmine is warm, and it should be placed in a sunny place, which is more drought-tolerant. Don't water it too much, causing excessive growth or "rotten roots". Apply thin fertilizer once a month, preferably liquid fertilizer, which is more uniform. Go to bed after winter and reduce the amount of watering. Applying phosphate fertilizer and potassium fertilizer before flowering can promote development and prolong flowering period. After flowering, cut and promote new branches, and at the same time turn over pots and prune roots.
Generally speaking, it is not difficult to make bonsai of winter jasmine, and the shape of the trunk is a little more complicated. If you want to raise roots, you should pay attention to the growth of roots. Before flowering, you should be watered enough, fertilized to promote flowers, more patience and more attention, which will give you a surprise.
