The Japanese maple, often referred to as Japanese fan maple (Acer palmatum) because of the characteristic shape of its leaves, has been enjoying increasing popularity for several years. This is hardly surprising, since the exotic deciduous tree not only needs little space, but is also very attractive. However, he is quite demanding and quickly gets brown leaves.
Both too much moisture and too much dryness can be the reason for brown leaves on the Japanese maple
Various causes are possible
Brown leaves on Japanese maples often appear first as brown leaf tips or edges and only later spread to the whole leaf. There are many causes 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 cultivate it in a bucket - only when the top layer of soil has dried. There should also be no water in the coaster.
dryness
In hot summer periods in particular, the damage described can also be caused by excessive drought.
heat
In general, the Japanese maple is not a fan of excessive heat, and some species do not tolerate direct sun either. It is therefore best to place the tree in semi-shade.
tips
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 do not put them in the compost.
