A deep watering done less frequently is better than more frequent, shallow watering. The goal is to have the soil evenly moist, not soggy or overwatered. There’s no such thing as a foolproof watering schedule since the environment is constantly shifting, but you can check your soil in between waterings to ensure it’s not drying out. - Source: Internet
• This is one of the most common but hazardous pests for the Japanese maple species. They have a white armored crust on top, within which the pests hide for protection. Their white armors are easy to spot when present on the stems and dark bars. Since they suck plant sap from within the stems and bark, you can see the leaves wilting earlier than the expected time, drying barks, and death in case of extreme infestation. - Source: Internet
• This is one of the most concerning problems with Japanese Maple, where an entire branch can be affected. The initial symptom is discoloration of leaves and dying. Then, it will spread gradually to other healthy leaves on the same branch, affecting the branch itself. If not removed at the initial sighting of the symptom, the maple bonsai won’t last for a long time. - Source: Internet
• Your Japanese Maple has holes in its leaves because of pests, heat, and if a tree is still young. Bugs, scale, mites, aphids, caterpillars, vine weeds, and worms are some leaf-eating pests that attack maple trees. If these frequent leaf feeders are overlooked, they can also attack the stems and kill the plant. - Source: Internet
• The japanese maple ‘Crimson Queen’ does not have many specific requirements for soil. It is a forest native, so it prefers well-drained soil that is rich in humus and slightly acidic . Its main root will extend deep into the soil, but its tiny fibrous roots will be concentrated near the soil surface, so accumulated water in the soil tends to cause root rot. - Source: Internet
• . The japanese maple ‘Crimson Queen’ is native to the margins of forests in China, Japan, and North Korea, so these trees generally prefer a humid environment.

But given a choice water the roots and not the tops. - Source: Internet
• Japanese maple scale seems to be a growing problem, mostly on the east coast. This type of scale insect is known as an armored scale because the insects protect themselves underneath an armored cover that is usually white in color.

Several factors like water and fertilizer levels, pesticides, or other environmental factors can lead to or intensify leaf browning. This condition of browning leaves is called leaf scorch. Read on to take a closer look at this problem, including details about the causes, what to look for, and some possible remedies. - Source: Internet
• Powdery mildew is inhibited by extreme heat and extended periods of rain.

It is recommended that, that is, cut off any old, coarse, diseased, and weak roots. - Source: Internet
• White spots or patches is probably due to powdery mildew that results in a dusty growth all over the top of the leaves. Similar to the brown spots mentioned above, white spots may cause the leaves to fall off as well, known as defoliation. If, however, you find white fuzzy patches on the tree’s trunk, it is probably lichens, which are normally found on trees that grow slowly, like the Japanese Maple. These fuzzy white patches are not a concern for the tree’s growth or health. - Source: Internet

If you have kept the bonsai in a humid area or under direct sunlight, the chances of powdery mildew grow by ten times. The related fungus also thrives when the leaves of the maple bonsai don’t receive enough air. - Source: Internet
• Aphids are sucking pests, often found in the leaves of the Japanese maples. These insects are relatively small and hard to identify. They take nutrients from the leaves, causing them to dry and fall off. Besides, the infestation usually occurs at a large scale, and multiple leaves are affected simultaneously. This reduces the canopy volume and minimizes the brilliance of the leaves. - Source: Internet

• Powdery mildew is a fungal disease that leaves a superficial, white, dusty coating on leaves of a wide variety of plants. The cause is a group of related fungi that each attack a limited number of closely related plants. Powdery mildew tends to create a problem for gardeners in middle to late summer, reducing the strength and damaging the appearance of infected plants, but rarely killing them. Phyllactinia guttata is the fungus that afflicts maples, and it can pass the infection to other trees including birch, horse chestnut, hornbeam and dogwood. - Source: Internet
• Aphids can and have been known to feed on Japanese maples, but in most cases it’s not a big concern. Aphids feed by attaching themselves to the leaves of a plant and sucking nutrients out of the leaves. If there are a number of aphids or if they are there long enough, they can damage the leaves to the point that the leaves curl up and could drop from the plant. However, aphids have a number of natural predators including lady bugs so they usually don’t last long once they appear. You can treat for them with an insecticidal soap or rinse them off with a blast of water. - Source: Internet
• Anthracnose is a fungal disease usually caused due to high humidity during the rainy seasons. Here, the fungus attacks the leaves and stems, forming spots throughout. Even if you prune the affected leaves and stems, the fungus will remain attached to the pruned plant parts. As a result, they can thrive on them before releasing the spores. Hence, if one leaf of the Japanese Maple is affected, all other parts will suffer from the disease if proper care is not taken. - Source: Internet
• When you water your tree, avoid spraying water on the tree’s leaves. Instead, irrigate directly at the base of the tree. Be sure to water in the morning, rather than in the evening so that the tree can dry during the day. Watering at night, although usually is more convenient, means water may settle on the tree’s leaves or trunks, which makes the spots worse. - Source: Internet
• Brown spots usually are an indicator of a leaf fungus known as leaf spot, especially if the spots are in a circular form. Another type of leaf disease that attacks Japanese Maples is anthracnose, which presents itself more in a free-form style of spots. In the beginning, either of these spots may seem insignificant, only affecting the aesthetics of your tree. However, severe cases of leaf disease can cause the leaves to fall off prematurely. - Source: Internet
