Bonsai ficus brown leaves: Answer: bonsai ficus

Dear Giancarlo,
from the symptoms you describe it is very likely that your ficus has received excessive watering, which has favored the development of root rot and stem; root rots are often caused by a fungus, called armillaria, which creeps around the roots and the stem, and subsequently attacks the tissues, like a parasite, and causes them to deteriorate first, often accompanied by the barking of the stems and a almost soft texture of the woody parts, and later death.
First of all it is essential to reduce the watering against this type of fungus, making sure that the soil dries up; so you can try repotting your ficus, so as to change all the soil, and in this way remove the underground part of the fungus. Prune the ruined and soft branches, and repot the plant with fresh soil, consisting of universal soil mixed with akadama. If you notice dark or black root parts, cut them, because they are damaged and will die.
Once repotted the bonsai, you can try to water it once with water added with a systemic fungicide, or a fungicide that instead of remaining in the ground it will be absorbed by the plant, and will enter the lymphatic circle, working from inside the plant and not by contact .
Later on you remember that ficus loves a warm and humid climate; this does not mean that they need daily watering or always wet ground; for humid climate we also mean the air, whose humidity will be increased by often vaporizing water on the crown of the bonsai.
Watering, on the other hand, should be provided only when you notice that the soil is drying; to check the best method is to insert a finger in the soil, if you feel the substrate is fresh and moist, it sends back the watering of at least one day.
Clearly the frequency of watering depends very much on the seasons, even when the plant is at home; this is because in winter even the evergreen plants have a sort of vegetative rest, caused by the fact that the hours of daily sunlight decrease.
So remember to water your plant only sporadically from September-October until March; spring and summer watering should certainly be intensified, but in any case avoid leaving the soil permanently wet, or soaking it with water; the strong humidity of the soil, and especially the water stagnation, favor the development of fungi and bacteria, which are very harmful for plants.
