Brown leaves can develop on Japanese maple at any stage. The factors that cause brown leaves on Japanese maple trees include low water levels, high temperature, pesticides, and soil nutrients.
As discussed in a previous post about the Japanese maple tree, we realized the maple tree grows well in the spring. The summer exposes the plant to unfavorable conditions. Here is a possible cause of brown leaves in the Japanese maple tree and how to solve them.
Why are my Japanese Maple Leaves Turning Brown?
1) Water levels
Japanese maple trees survive in cool and moist areas. So if you see your plant leaves turning brown, check the water level and the moist or dry environment, including its surroundings. In a much-dried area, you can use a garden hose to water it deeply for 1 or 2 days in a week.
2) Direct sunlight
The maple tree loves to grow under shade. Any direct sunlight source might cause the brown leaves you see on your Japanese maple tree. Make sure to relocate the plant away from direct sunlight.
3) Pesticides
Aphids are common on Japanese maple trees. When using pesticides to control Aphids on maple trees, it is highly recommended that you do not leave pesticide residues on the leaves, which results in turning the leaves brown after long usage.
4) Soil nutrients
The absence of soil nutrients can also result in your Japanese maple tree leaves turning brown. The tree does not need much fertilizer; however, fertilizer application may be necessary for critical situations.
How to treat brown leaves on Japanese maple trees?
- Relocate the tree if there is direct sunlight on the plant.
- Remove the dead leaves from each branch.
- Water the plant frequently to keep it moist but not wet.
- Apply fertilizer
Conclusion
Japanese maple tree leaves turning brown is a normal occurrence. The plant can re-leaf in the early spring. Also, when you decide to apply fertilizer to the Japanese maple tree, do it in the early mornings when atmospheric humidity is high. Let’s know in the comment what you think. Thank you for reading.
