Thank you Rainbow Gardener. This is so refreshing to hear !! and if you look closely at the picture, you can see many new buds appearing...
The bonsai sits at my desk indoors at the office, so I wasnt sure if it needed to be outdoors, as in the evenings there is no air con. ?
The soil always feels dry and that is way I water it every few days. Should I change the type of soil? I see little white balls within the soil. Is this a worry?
You haven't said where you are, what season you are in, what the temps are, etc. The fact that you mention air conditioning makes me think you are somewhere in the southern hemisphere. In the growing season, it would probably be better for it to be outside, but ficus are pretty adaptable. I have a full size (non-bonsai) ficus, that is indoors most of the time and on a shady screened porch the rest of the time. But the A/C is very drying, so it is better for it to be off. Ficus are native to the tropics and the heat does not bother them.
When I said before repotting, I meant changing the soil. " In spring you should repot it into a more free draining bonsai soil (which will be mostly inorganic and quite gritty" I said in spring, because I am in winter. I wasn't thinking about you being in summer. So probably once you get through the heat of summer would be a good time to get it in to better soil.
The little white balls are something like perlite or vermiculite. They are mineral and are added for better drainage, air and water circulation.
Do a little reading about ficus bonsai care.
