First, the growth habit of maple: like scattering light, resistant to shade and cold. It is suitable to grow in a cool, moist, loose and fertile neutral soil environment with good drainage. The southern region can spend the winter outdoors, and the greenhouse or shed in the northern region is a better choice.
Second, the shape of maple bonsai: let's take a look at the common modeling styles: straight dry, oblique dry, curved dry, double dry, waterfront and temporary. The new branches of maple trees are long and soft, so we give priority to pruning, supplemented by binding. The maple leaf bonsai is a foliage bonsai, and it is perfect to trim the leaves into a natural style with high and low coordination and good density. After the first frost, the red leaves are bright and dazzling. The so-called red leaves are the most affectionate, and a word sends acacia!
Three, maple bonsai planting and pot soil selection:
The best planting season of maple is February-March every year. Prune the roots and branches before planting, then remove half of the old soil under the roots and replace it with new soil. A layer of decomposed bean cake base fertilizer can be placed at the bottom of the basin. Considering that maple likes fertile, loose and moist soil, it is suggested that two-thirds of humus soil and one-third of sand can be mixed when planting maple. When choosing a pot, we should consider the change of maple leaf color, and it is best not to use red and green purple sand or pottery pot.
Maintenance and management of maple bonsai: 1, placed in a cool and ventilated place with scattered light. Maple likes a cool and humid environment. If placed under strong light or balcony, dead leaves will appear. It is best not to leave it indoors for more than a week, otherwise it will slow down the growth due to poor ventilation. In addition, in wintering areas, the north can be placed in greenhouses or greenhouses. In the south, just put it in the leeward and sunny soil.
2, reasonable watering. Maple bonsai is famous for its branches and leaves. Considering its large leaves, it evaporates quickly. During the growing period, at least once a day. In hot summer, sprinkle water on or around the ground to keep the air moist and clean the dust on the leaves. Winter enters a dormant period, and the basin soil can be slightly wet.
3. Scientific fertilization. Follow? Thin and diligent application? In principle, in the spring germination and long leaf period, it should be a decomposed and thin organic liquid fertilizer. In addition, the same is true in August-September. Stop fertilizing in winter dormancy and rainy days. The rest of the time is once every half month according to the growth situation.
Step 4 trim the shape. Maple trees germinate vigorously, so sometimes we see many new buds growing on the trunk. In order to save nutrition and ventilation, unnecessary new shoots and too dense branches should be cut off in time. The best time to watch the maple leaf bonsai is when the leaves are just exposed. At the end of August (late summer and early autumn), you can pick the old leaves and apply a layer of decomposed thin liquid fertilizer, which will give you another chance to watch the leaves. Isn't it beautiful?
5, pest control. The main pests and diseases of maple bonsai are aphids, powdery mildew, stem borers and so on. We should find out in time and take preventive measures as soon as possible. If it happens, we can clean the leaves with a toothbrush and disinfect them. If the situation is very serious, take chemical precautions. For example, for heart moths, 40% omethoate can be injected into the damaged part of the trunk with a syringe.
