If a fig tree shows brown leaves, this can have various causes. In addition to unfavorable site conditions, fungal diseases or incorrect watering are possible causes of leaf drop.
Why does my fig have brown leaves?
Brown leaves on a fig can be caused by waterlogging, too little watering, leaf burns, lack of nutrients or fungal diseases. Pay attention to optimal soil conditions, sufficient watering and avoid excessive sunlight or fungal infestation.
Waterlogging causes the leaves to dry up
Figs love dry, warm substrates and are very sensitive to too much water. Waterlogging causes the roots to rot, the plant can no longer absorb water, and the leaves dry out and turn brown. In this case, ensure that the fig has optimal soil conditions.
Water enough
If the soil is too dry, the plant cannot absorb water from the soil. It tries to protect itself from withering by shedding parts of the leaves prematurely. Figs planted on house walls with protruding canopies in particular often suffer from their dry location. Therefore, water fig trees that you have planted near your house sufficiently in the warm summer months.
Leaf burns
In addition to strong sunlight, the unbalanced supply of certain s alts or a lack of potassium and magnesium leads to leaf browning. Even if insecticides or fungicides are used incorrectly, the leaves can turn brown and fall off.
Fungal diseases
If the fig tree is attacked by rust fungi, the leaves also turn brown. What is characteristic of this plant disease is that small reddish-brown spots initially appear on the leaves, which gradually close until the leaf finally falls off.
