What are the causes of maple with brown leaves?
Brown leaves on maple trees can be caused by incorrect location or care, such as exposure to wind, drought stress, waterlogging or sunburn. In the rare case of verticillium wilt, clearing and soil replacement is necessary.
Errors in choosing a location and caring for them cause brown leaves
Tree diseases are usually not the source of problems when the leaves on the maple turn brown. With this damage, the tree or shrub signals dissatisfaction with the location or care. The following tips summarize common causes and solutions:
- Wind-exposed location: transplant maple to a place protected from the wind
- Drought stress: water regularly as soon as the surface of the soil has dried
- Waterlogging: Water maple in the bed less, repot in dry substrate in the bucket
- Sunburn: change location to a partially shaded spot or shade in the midday sun
If brown leaves only appear in places on the maple, verticillium wilt has struck. This disease is still incurable and highly contagious to neighboring trees. In this case, you cannot avoid clearing and extensive soil replacement.
