Maple loses leaves - tips on causes and countermeasures
The hand-shaped or slotted leaves are the maple's most beautiful jewelry. If the tree or shrub prematurely drops its leaves, it signals a disturbance of well-being along the way. The common causes of premature leaf loss with tips for effective countermeasures summarizes this guide.
Cause # 1: Drought stress
The water requirement of maple trees is sometimes underestimated. Especially during hot summer days the Flachwurzler are threatened by drought stress. The woody sees itself threatened in its existence and throws the leaves off for self-protection. How to act correctly:

Cause # 2: Diseases and pests
Most maple species are susceptible to fungal attack and lice. If you can rule out drought stress, please check the maple for the following diseases and pests:
If you can identify aphids as culprits, combat the pests with a solution of 1 liter of water and 50 grams of soft soap and 1 teaspoon of spirit. Please note that leaf loss continues until all pathogens or pests have been destroyed. Ecological control agents should therefore be used repeatedly.
Cause # 3: Sunburn
Maples love a sunny to half shady spot. However, the trees are not among the unconditional sun worshipers. Under the influence of blazing summer sun at lunchtime, the leaves suffer a sunburn, wither and fall off. Classic symptoms include yellow to light brown spots with a dark border, brown leaf tips and edges.
For maple in the pot, an immediate change of location can stop leaf loss. Maple in the bed temporarily receives shade and should be transplanted in autumn.
