Answer: bonsai

Dear Silvia,

ficus ginseng, or ficus retusa, are very cultivated plants as bonsai, because they are resistant plants, which can also bear some cultivation errors; clearly, moving from the shop, where she certainly received all the necessary care, to your home, can be a source of stress. Usually the symptoms of black, crumpled or spotted leaves are related to the development of rot in the soil, but since I have no other indications on the plant, or a photograph, it is good to consider all the options. Ficus ginseng tolerates drought quite well, but they prefer a cool and humid climate; this means that they like to be watered regularly, in order to keep the soil slightly moist; wet does not mean soaked in water, and excess watering, which results in a soil that is always soaked, quickly leads to the development of root rot, which can damage the plant even heavily. If the soil of your bonsai is always soaked, and the plant shows symptoms of suffering, it is the case to repot it, to remove the parts of damaged roots and also the soil, to replace it with fresh soil. The correct watering of the ficus is provided when the soil begins to dry: with your finger, check that it is dry, and water abundantly. Often poor quality bonsai have a rigid and hard earthen bread, on which the water flows, without wetting it; in these cases it is advisable to water by immersion: place the pot in a basin, and fill with water up to the outer edge of the pot; when the soil is moist on the surface, the pot is drained and placed in the home. This watering method is certainly the best for bonsai, because it ensures that the soil is well moistened in its entirety. Another problem related to bonsai concerns environmental humidity; the air in the apartment is constantly dry, especially when we have the heating system or air conditioning on; therefore it is good to periodically vaporize the foliage, or place the pot on a tray with at least 3-4 cm of gravel, which must be kept moist, in order to increase the ambient humidity. In the cold months, watering will be sporadic, but try to keep the gravel under the pot looking wet, especially if the room where you keep the bonsai is very heated.
