24 Unexpected Facts About White Spots On Japanese Maple Tree | Japanese Maple Fungus Treatment
- 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
- 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
- Verticillium Wilt is a disease that can attack Japanese maples. Symptoms are pretty obvious. In some cases the leaves on a single branch will discolor and die, but do not fall from the tree. This often happens in late summer or early fall. In many cases the branch dies completely and should be completely removed from the tree at first sign of the disease. - Source: Internet
- Japanese maples are actually pretty tough trees and quite disease resistant. Usually, if a Japanese maple is failing, or doesn’t look good, it’s not from disease but other issues that are pretty easy to correct. First let’s look at the things that you can control. - Source: Internet
- This is one of the most common diseases that most Japanese maple bonsais are affected by. Here, the top surface of the leaves forms a white, powdery layer caused due to mildew fungus. 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
- As soon as somebody has a Japanese maple, or any plant for that matter, that doesn’t look good they immediately think it’s being attacked by some dreaded disease. In most cases that’s not the case at all. Contrary to what most people think, Japanese maples are pretty easy to raise and care for. For the most part they are usually care free plants that happily exist in just about any landscape. But there are a few things you should know about them. - 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
- They don’t like wet hair! Japanese maples don’t like to have their leaves sprayed with water when the sun is out. The water droplets act as mini magnifying glasses and can leave burnt spots on the leaves. This isn’t a serious problem and not one that I worry a lot about. But given a choice water the roots and not the tops. - 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
- Powdery Mildew is a fungal disease than can attack Japanese maples. I’ve never seen it on any of my Japanese maples, yet I’ve had bad cases of it on some of my dogwood trees. Powdery mildew is easy to detect because it covers the upper side of the leaf with a white powdery film. It thrives in hot, or hot and humid conditions, especially where a lot of plants are grouped together and air circulation is poor. - 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
- 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
- Getting rid of brown leaf spot, anthracnose, white spots or lichen is rather easy. The good news is that none of these discolorations are cause for major concern, although you may need to spend a little time and put forth some effort to get rid of them if you want your tree to look stunning again. While applying a fungicide may seem like the best idea, it isn’t always necessary. Here’s what to do instead. - Source: Internet
- While the presence of white, fuzzy colonies of wooly alder aphids on a maple tree may cause alarm, they don’t cause serious harm to infested maples. (Damage is usually limited to the loss of some leaves.) Large wooly alder aphid populations usually collapse from predation and parasitism. Control efforts are not necessary. - Source: Internet
- First, the wood on the ground has mold and fungi that are growing as the logs decay. This is normal and is not related to the issue on the live maples. Second, the black spots on the leaves in summer are likely tar spot. The amount of tar spot that develops usually depends on whether or not a summer is particularly wet or dry and rarely affects the health of the tree overall. - Source: Internet
- Good afternoon! I have a small japanese maple that I got as a seedling last summer. It’s in a pot, sunk into a garden. The leaves came out fine this spring, but now it’s developing these tan sort of bleached-out spots. Any idea what this is and what should be done about it? - Source: Internet
- Twice I’ve had fairly large branches on my Acer palmatum dissectum maples die back all the way to the trunk of the tree and I have to assume it was caused by Verticillium Wilt. But what’s really important to note is that even though these two trees lost large branches that had to be cut out, leaving a large hole in the tree, within a couple of years the trees filled back in and are once again nicely shaped and beautiful. And they’ve stayed healthy since. - Source: Internet
- Verticillium Wilt is caused by a soil borne fungi but usually attacks plants that have been stressed by other things. Drought, frost, or wet soil. There’s really nothing you can do to treat your Japanese maples to prevent this disease and there’s nothing you can apply once they have it. It’s something that just happens. - Source: Internet
- High soil alkalinity and nutrient deficiencies in the tree can be corrected by adjusting the soil pH and soil enrichment with organic material. The ideal soil pH range for maple trees is between 5.5 and 7.3. It can be lowered by using organic mulch, which coincidentally, will provide nutrients to your tree. - 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
- 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. They are easy to spot on the stems of trees with dark bark. Scale insects are a sucking insect that extract plant sap from the host plant. In plants with heavy infestations premature leaf drop, branch die back, or death of the plant can occur. - Source: Internet
- If mushrooms are growing on your maple tree’s trunk or roots, you may have a severe problem. The presence of mushrooms and mushroom conks is a sign that the pulp of your tree is rotting. The fungi that produce mushrooms (the fruiting body of the fungus) flourish when fed by decaying organic material. - Source: Internet
- The white spots that you see are in fact thousands of tiny white bugs. They are often mistakenly identified by homeowners as mold or parts of the bark. Scale insects can be flat, small 1/16” long flecks, while others can be larger bumps almost the size of a ladybug, covering smaller twigs. - Source: Internet
