we have a Ginseng Bonsai at home since the end of August, we put it in a sunny room but without direct light, and we avoided drafts, I noticed that it puts new leaves, but the old ones are all graying crumpling and falling , and many of the new ones have the tips burned ... what are we doing wrong? before it was in a mall can it be the change of environment? ...
ficus ginseng, or ficus retusa, are highly cultivated plants like bonsai, because they are resistant plants, which can also bear some cultivation errors; clearly moving from the store, in which he certainly received all the necessary care, at your home, can be a source of stress. Generally the symptoms of black leaves, crumpled or with spots are related to the development of rot in the ground, but since I have no other indications on the plant, or a photograph, it is good to consider all the options. Ficus ginseng tolerate drought quite well, but prefer a cool, damp climate; this means that they love to be watered regularly, in order to keep the soil slightly damp; wet does not mean soaked with water, and excessive watering, which results in a soil always soaked, quickly leads to the development of root rot, which can ruin 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 ruined roots and also the soil, to replace it with fresh soil. The correct watering with 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 hard and hard earth bread, on which the water flows, without wetting it; in these cases it is advisable to water by immersion: place the pot in a tray, and fill it with water up to the outer edge of the pot; when the soil is moist on the surface, the pot is drained and stored away. This method of watering is certainly the best for bonsai, because it guarantees that the soil is well moist 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 conditioner active; therefore it is good to periodically vaporize the foliage, or place the vase on a tray with at least 3-4 cm of gravel, which will be kept moist, in order to increase the environmental humidity. In the cold months, the watering will be sporadic, but try to keep the gravel under the pot seems wet, especially if the room where you keep the bonsai is very heated.
