Maintenance method of five-needle pine bonsai (cultivation method and matters needing attention of five-needle pine)
Five-needle pine is luxuriant in branches, beautiful in leaves and short in needles. It has always been one of the excellent tree species for making bonsai and is deeply loved by bonsai lovers. The following introduces the maintenance and management methods of five-needle pine bonsai. In this way, you can also cultivate beautiful five-needle pine bonsai.

A, basin soil requirements

Loose, fertile, slightly acidic soil, preferably natural native soil, should be selected for potted Pinus pentaphylla. You can also prepare nutrient soil for planting American ginseng, and mix 3 parts of humus soil, 5 parts of garden soil, 1 part of compost and 1 part of sandy soil evenly as nutrient soil. It is best to choose a purple sand basin with beautiful appearance and good ventilation for potted five-needle pine, which not only has good ventilation, but also has better ornamental effect with five-needle pine.

Second, the watering requirements

Five needles pine likes humid environment, as long as the soil in the basin is kept moist every day to avoid water accumulation in the basin. During the germination and vigorous growth period of spring, water control management should be properly carried out to avoid excessive watering, which will cause long branches and leaves and long pine needles and affect the ornamental effect. It is hot and the temperature is high in summer. To avoid watering at noon, it is best to water in the morning or after sunset, and often spray water on the leaves to humidify them. Water should be reduced after winter, as long as the soil in the basin is wet, it can be watered around noon when the temperature is high.

Third, fertilization management.

Potted pine needles should not be fertilized too much. Excessive nutrients can easily make its branches and leaves white and pine needles long, thus affecting the ornamental effect. Therefore, the principle of daily fertilization is "thin fertilizer and less application". Applying organic fertilizer twice in spring and autumn can meet the nutrients needed for growth, and the cake fertilizer that is fully decomposed in spring is suitable. Fertilization in spring is about 3 months before germination to promote the germination of new buds. September is the rapid growth stage of Pinus pentaphylla, so when fertilizing in autumn, the concentration of fertilizer and water can be increased to make the branches grow thicker and improve the ornamental value.

Fourth, sufficient light.

Pinus pentaphylla is a light-loving plant. When cultivating, it is best to put potted plants in a ventilated and well-lit place. Long-term lack of light will affect the normal growth of plants. In hot summer, shade the sun properly at noon to avoid sunburn and affect the viewing effect. Sufficient light can make the five-needle pine bonsai grow dense needles and be greener.

Fifth, trim the shape.

The common shapes of five-needle pine bonsai are straight-dry, inclined-dry, curved-dry and cliff-like. Go straight to the invasion, dignified and steady; Inclined stem is like birth, natural and elegant beauty; The curved dry type is vigorous and dynamic; There is also a sharp turn like a cliff, which is thrilling and graceful, and every different modeling feature is interesting and natural!

The pruning time of five-needle pine is from early winter to early spring, and it is appropriate before the juice begins to flow. It is best to seal the wound with wax and tape after pruning to avoid turpentine from flowing out. Plastic surgery generally adopts a combination of Pinza and pruning. Cut off the branches that are too long, and then use wire to shape the branches that need special shapes. Cut off the branches that are too dense to affect the shape in time.

The shape of the five-needle pine bonsai depends on the wood, and it should be shaped according to the situation, so as to keep the natural trend of the tree bonsai as much as possible. Such bonsai modeling will add natural harmony and be more ornamental.
