Answer: ficus without leaves

Dear Mercedes,
ficus trees, especially bonsai ones, tend to lose their foliage for various reasons, even simply because they have been subjected to an air blow or because they are moved from inside the house to the terrace. To understand what the problem is, it would be useful to know how this ficus is cultivated, because a plant that is cultivated in the best possible way usually does not show symptoms similar to the loss of leaves. So, to have a healthy and always in shape ficus bonsai, you have to place it in an area sheltered from direct sunlight, but with a good brightness; at home it is good to find a position where it does not undergo sudden changes in temperature, and therefore away from drafts on doors and windows. Watering is provided only when the soil is dry, and therefore more often in summer, only sporadically during the autumn and winter months; the fertilizations are to be added to the water from March until September, while in the remaining months it would be appropriate to avoid fertilizing, as the plant is in vegetative rest, and therefore does not require fertilizer of any kind. The air in the room where we keep the ficus should be fairly humid, and not excessively heated, so we often vaporize the foliage or move the plant outdoors as soon as the nighttime minimum temperatures are above 15-18 ° C, given that outdoors the air is naturally more humid than in the home. If our house is very hot and dry, the vaporizations on the foliage should also be done every single day. We avoid the excesses of watering, and above all the water stagnation, which causes the development of rotting in the ground, which quickly cause the fall of the foliage. Ficus bonsai, especially in the first years of life, should be repotted every year, or every other year; the best period is the end of winter or autumn, but if you have not repotted your bonsai for a long time, it is advisable to repot it now, trying not to ruin the roots, since the plant should be in full vegetative growth. The total loss of the leaves could also be painful to several causes that occur simultaneously, or even to the presence of parasites in the soil or on the vegetation.
