How to grow Acer palmatum

1. Maintenance methods

1. Temperature: The Japanese maple prefers a warm growing environment and can withstand certain low temperatures. In winter, as long as the temperature is kept between zero and five degrees, it can survive the winter normally without being affected. However, if planted in the north, it is necessary to keep warm. It is best not to choose to spend the winter outdoors, otherwise frostbite will occur.

2. Watering: During the growth period of the Japanese maple, just keep the soil moist. Water it thoroughly and do not allow water to accumulate. The demand for water is not very large during the seedling period, but it will increase as the plant grows, so watering needs to be decided by observing the growth conditions of the plant.

3. Light: The Japanese maple is a semi-shade plant and cannot be directly exposed to strong light. The branches and leaves of the plant will appear scorched after being exposed to strong light. So in summer you can transplant it to a cool place or provide shade for it. It only needs warm, oblique light during the growing period.

4. Fertilization: Be careful not to apply nitrogen fertilizer exclusively. You can apply a thin layer of fertilizer water once in the spring, and focus on applying phosphorus and potassium fertilizers during the growth period. Such reasonable fertilization will make the branches and leaves more colorful and the ornamental value will be higher.

2. Breeding techniques

1. Reproduction: Cutting and sowing are two important methods of reproduction. When cutting, cut the tender branches into small sections of about ten centimeters, and then replant them. The most suitable temperature is around 27 degrees. The seeds of the Japanese maple are harvested in autumn, and the best time to sow is in spring. The seeds should be buried about two centimeters deep in the soil, then covered with some straw and wait for germination.

2. Pruning: As an ornamental plant, the Japanese maple needs to be pruned reasonably to ensure normal viewing. Pay attention to the sense of layering, pay attention to its growth on a daily basis, and cut off some poorly growing side branches.

3. Problem diagnosis and treatment

1. Disease: Leaf blight will occur, which will seriously affect the appearance. The edges of the branches and leaves will begin to dry up, and eventually the branches and leaves of the plant will wither. You can cut off the diseased branches and leaves in advance, or use pesticides to prevent it.

2. Pests: Scarab beetles will occur, mostly in summer, and can be controlled by spraying dichlorvos solution.
