bonsai, tips – Bonsai Questions and Answers

A short time ago I was given a bonsai but I was told little about it. I deduced that it is a ficus ginseng seeing various photos on the internet. They told me that it is preferable to leave it outdoors and so I only did that there were particularly windy days so I decided to put it in the house. This morning looking at it I noticed that in the center there are a couple of yellow leaves. What could it be due to? In the air currents?

I always move it because I don’t really understand where it can be better. The pot below does not have holes so I can not understand how often I should water it and the amount, also I would like to understand if I have to expose it directly to sunlight or not in the short term that temperatures will rise … the pot has a diameter and a height of fifteen centimeters and the plant including the leaves will be a 25 cm. Thank you in advance for your availability 🙂

Response : bonsai, advice

Dear Sabri,

ficus are tropical plants, which do not bear temperatures below the 10-12°C, therefore they are commonly cultivated indoors, when the external temperatures are lower than this minimum; therefore, from April-May, till autumn, we can easily cultivate our ficus in the open air, considering also the fact that the air in the house is often too dry, in winter due to the heating, ine state because of the air conditioning, whilst in the open air the climate and the humidity present in the air are more natural.

If it is possible for you, it would be advisable to cultivate your ficus outdoors, on the terrace or in the garden, avoiding areas that are too windy, and also direct sunlight, especially during the hottest hours of the day and in July and August. Therefore, find a fairly sheltered position, but well-lit, without the plant being affected by direct sunlight. Growing conditions with good light help you to keep the plant healthy.

The size of the pot you indicate seems a bit or odd for a bonsai, which usually have shallow pots, up to 5-6 cm high, with large drainage holes on the bottom. In the long run, your plant will suffer a lot from remaining in that pot, first of all because the absence of drainage holes causes water stagnation, and also because a bonsai placed in a very deep pot tends to have an excessively elongated root system, which also affects the plant and the leaves.

In my opinion, it would be the case to say to pot it in a much less deep container, and with some nice drainage holes, filled with a mixture formed by akadama and universal soil in equal parts. Watering is provided when the soil is dry, trying, however, to avoid drought.

In order to ensure that, at the moment of the watering, the soil is well watered, it is watered by immersion, placing the whole pot in a container, where the water is placed up to the outer edge of the pot, keeping then that the soil is all wetted up to the surface.
