The Japanese maple, often referred to as the Japanese maple (Acer palmatum) because of the characteristic shape of its leaves, has been enjoying growing popularity in recent years. This is hardly surprising, as the exotic deciduous tree not only requires little space, but is also very attractive. However, it is quite demanding and quickly turns brown leaves.
Why is my Japanese maple getting brown leaves?
Japanese maple often gets brown leaves due to waterlogging, drought or heat. To avoid this, water only when the soil layer has dried, ensure sufficient moisture and place the tree in partial shade. Fungal diseases can also cause brown leaves.
Various causes come into question
Brown leaves on the Japanese maple often first appear as brown leaf tips or edges and only later spread to the entire leaf. There are many reasons for this phenomenon.
Wetness
One of the most common reasons for brown leaves is excessive moisture, especially waterlogging. Therefore, only water your Japanese maple - especially if you are growing it in a bucket - when the top layer of soil has dried out. There should also be no water in the coaster.
drought
Especially in hot summer periods, the damage described can also be caused by excessive dryness.
Heat
In general, the Japanese Japanese maple is not a fan of excessive heat; some species cannot tolerate direct sun either. It is therefore best to place the tree in partial shade.
Tip
In addition to the causes described, various fungal diseases can also cause the brown leaves. In this case, cut away the affected areas and dispose of them - but please not in the compost.
