Black Pine Hi Fat:
Black pine prefers fat. Planting the flower soil of black pine can add a part of the humus soil when mixing the flower soil. Use red brick debris to pad the bottom of the pot, and then use (weathered rock + humus + pastoral soil) to take one-third each and mix. The new flower soil is loose and breathable, not easy to accumulate water, suitable for the growth of black pine. Large stump bonsai, you can add a small amount of cooked "sheep dung balls" at the bottom. As a bottom fertilizer.
General pine trees like "skinny soil" and "skinny". However, black pine prefers fertilizer, and when it comes to daily maintenance, it should be used every month to cook soybean cake fertilizer, animal manure water, supplement various nutrients based on "nitrogen" to promote the growth of branches and leaves. The way of burying is to supplement "phosphorus and potassium" in spring and autumn, at least once a month. More nutrients, promote the enlargement of the main branch, promote the multiplication of lateral buds.
Black pine likes to be wet:
The biggest difference between black pine and ordinary pine trees is that black pine prefers to be wet, but other pines need to be "dry-fed". Black pine is the only pine tree that can be grown using semi-hydroponics. The seedlings of black pine are held in the moss at the root, and the center of the moss is placed with flower soil suitable for the growth of black pine. Fill a shallow basin with water and soak 1/5 of the moss balls. The roots grow outside the moss and are mostly white roots. This feature is not found in other pine trees.
Black pine bonsai is timely for daily maintenance and is often misunderstood as "dry farming". Many people think that the surface of the black pine soil is wet, and the drying time should be extended until the flower soil is completely dry before watering. This is fatal. Such maintenance can only maintain the survival of the black pine at the lowest bottom line to maintain moisture. Black pine cannot be allowed to grow. When the black pine is replenished, except for spring, the surface of the flower soil is dry, and it can be watered immediately. This is also the difference between watering under daily maintenance.
Black pine likes light and ventilation:
The maintenance site of black pine must meet the iron conditions of sufficient light and good ventilation. No matter how to manage and how to maintain in the later stage, the environmental impact has many growth problems, the maintenance location is not ventilated, the light is insufficient, then what follows is that the flower soil is wet for a long time and the roots are rotten. Diseases and insect pests will be the first to invade the poor environment of the black pine.
The maintenance of the place of black pine needs to be raised in the pot, the need for a well-ventilated, well-lit environment, even if the summer high temperature, as long as it does not exceed 40 degrees, it does not need shade. At high temperatures, it is best to use a spray to wet pine needles and wet the area around the pot to cool the environment and increase humidity.
Black pine is more resistant to pruning and easier to bud:
In May and July, prune the branches of the black pine, leave the pine needles that need the position, cut off one-third of the bud head, and leave 5 pine needles on the bud head, all of which can form new bud points in the later stage. The pruning of black pine, as well as the budding, the effect is more ideal. The success rate is also high.
The pine needles of black pine are thicker, and the pine needles are longer in the stocking state, even if the daily maintenance is not done in a timely manner, but the needle picking needs to be carried out all year round. Sometimes, picking needles will have unexpected effects, that is, long and direct, and be forced out of new shoot points. In terms of germination, black pine is better than native pine trees.
The above is the difference between the daily management of black pine and ordinary pine trees, and the method of maintenance. If there are different methods, please leave a message, comment area, communicate with each other, and learn from each other. Thank you.
