Five-needle pine bonsai maintenance skills: I am afraid of more fat. The requirement for the five-needle pine fertilizer is thin fertilizer and less application. Only a thin liquid fertilizer can be applied every year from August to October. If the spring grows vigorously, you can apply less, and you can't apply fertilizer at ordinary times. It is often suspected that it is slow to grow up and wants to apply more fertilizer to make it grow faster. The result is counterproductive. Second, afraid of water in the basin. If too much water is poured, the air circulation in the basin will be blocked, causing the roots to rot and the branches to wither. As the saying goes: "Dry pine wet cypress" is the reason. Three are afraid to change the basin. It takes only 3 to 4 years for the pot to be changed, and the time should be from late September to early October, or from February to March. However, some pine-growing people chose pots for the styling, but they changed the basins when they were uncomfortable. As a result, they died because they changed the basin too hard. When you want to see more sunshine, it is best to put it in a sunny place. When the air is dry, you can spray water twice on the leaf surface in the morning and evening. Second, pruning should be carried out during the dormant period to prevent excessive sap loss and damage its vitality. Third, winter should be maintained in a ventilated, sunny, warm, humid, smoke-free room. Fourth, we must constantly observe and timely control pests and diseases.
