As the five-needled pine bonsai grows over the years, some branches will grow too long, the five-needle pine will be too dense, or the location will be inappropriate, so it needs to be reshaped every year. The best time for shaping is from November to March of the following year, because during this period, the five-needle pine is in the dormant period, the sap flows slowly, and there is less rosin leakage after pruning. Plastic surgery generally uses a combination of pruning and pruning. For branches that are too long, either cut them short or tie them into irregular "S" shapes with metal wires to shorten them. Branches that are too dense and that are not needed for their shape must be cut off. Some beginners feel that it is a pity to cut off only a few branches a year, and they are reluctant to cut them off. In fact, if they should not be cut off, they will be burdened by it. The branches are too dense and disorganized, which will seriously affect the shape and artistic conception of the bonsai.

Plucking buds is an important plastic surgery measure to maintain the beauty of the five-needle pine bonsai tree. When the five-needle pine sprouts every spring, in order to shorten the length of the branches and ensure proper density of branches and leaves, in addition to controlling fertilizer and water, the buds that are not needed for the shape must be removed in time. The remaining buds should also be removed by 1/2-1 depending on their length. 2/3. The time for picking buds should not be too early. Wait until the leaf buds and flower buds are clearly distinguished. There is a string of flower buds at the lower part of the flower bud. After the flowers fall, they form a long leafless branch. It is best to remove these buds, but they can also be retained if the shape requires it.

Five-needle pine is suitable for growing in loose, fertile, slightly acidic soil with good drainage. If the alkalinity is too high during potting, the needles will turn yellow and fall off, so natural mountain soil is the best potting soil. The proportion of potting soil is 3 parts of leaf mold soil, 5 parts of garden soil, 1 part of compost, and 1 part of sandy soil mixed into nutrient soil. Generally, the pot should be repotted every 2 to 3 years, and the repot time should be from February to March or September to October.

Five-needle pine is a positive tree species and should be maintained in a sunny place in spring, autumn and winter. The needles are short and strong, and the leaves are green. On the contrary, the needles are thin and easy to wither and turn yellow. However, in hot summer, avoid the scorching sun around noon to avoid scorching the needles. Spring and autumn are the growing seasons of five-needled pine. The pot soil should be kept moist to promote the growth of branches and leaves. In summer, five-needled pine grows slowly and enters the dormant period, but the water evaporates greatly. Water it once every morning and add water to the leaves in the evening. Spray water on face once. In winter, control watering and maintain the lowest temperature. After the five-needle pine takes shape, do not apply too much fertilizer, otherwise it will easily damage the roots.

The five-needle pine potted plant should choose a dry and ventilated environment. Too much humidity and too much shade will be detrimental to its growth. Watering should be done properly, generally once a day in spring and autumn, twice a day in summer, and once a few days in winter. At the same time, pay attention to weather changes and be flexible. It is better to water with natural water. If you use tap water, you can keep it in a tank for a few days and then water it.

Five-needled pine does not have high requirements for fertility. Fertilization should not be excessive or too concentrated. Excessive fertilization will make the branches and needles elongated, hindering the ornamental value. Generally, fertilization is only done twice during the growth period in spring and autumn. In spring, organic liquid fertilizer (cake fertilizer and water) is applied once before germination or after thickening leaves. Fertilization in autumn can be appropriately concentrated to promote healthy growth. Stop fertilizing after October.
