What is the reason why the leaves of eucalyptus are black?

Reasons for the blackening of eucalyptus leaves and treatment methods:

1. The weather is too cold, and the freezing damage is serious

The biggest reason for the blackening of eucalyptus leaves is that the temperature is too low, and the frozen leaves cause blackening. In this case, the frozen leaves can be removed. Remember that the winter temperature of potted eucalyptus is 10-15 degrees. Good, proper watering, not too much. If the leaves are black, you can put the potted eucalyptus in a place with a higher temperature, so that you can come out with green leaves, but remember that if the temperature is too low, The frozen condition is more serious and the vitality is lost for a long time.

2. too much watering, root rot

If the eucalyptus is too much water, it will cause the roots to rot. In this case, the roots of the eucalyptus are damaged. The eucalyptus can be dug out, dried in a ventilated place, and the decayed roots are cut off, disinfected, and replaced. The branches and leaves can be trimmed, and after about 10 days, the eucalyptus will grow again.

3. Environmental pollution is more serious

The eucalyptus potted plants should be placed in a place with little clean and dust. If there is too much dust, it will be dirty and black. At this time, move the potted eucalyptus to a clean environment and clean the leaves.

Note: Eucalyptus should be placed in a well-ventilated place with no sunlight. Do not pour too much water during the growing season.
