Although many bonsai artist stick with outdoor trees when not living in the tropics, most of them do have some trees indoors. A lot of the time it’s a ficus. I also have a couple of them. Ficus are easy bonsai to keep indoor because they are able to survive and even slightly adapt to the harsh conditions our living rooms have. Dry air with minimum humidity, drafts, temperature fluctuation and low light. I’ve seen ficus trees that barely get watered with almost no soil, dry and full of cracks and still they had some branches with leaves. Now that isn’t the reason I keep them it’s more about that ficus are the only trees I can keep alive in my house that comes close to bonsai as I know it. I’ve tried many species but they all wouldn’t last long except for my ficus. I defoliate them, repot them any time of year and prune them yet still keep growing happy and show new growth all the time. Today I cleaned up the tallest of them it’s a tiger bark ficus. It’s about 24inch that will be 60cm, it had grown free for a while and the silhouet wasn’t all that anymore and has decent ramification on every branch which is really nice.
But it needed some thinning and pruning. Also wired some of the branches into place. The good thing about a tiger bark is that you can actually wire and bend branches without breaking them. My experience with other ficus species is that with them it’s only possible to wire and bend the young new growth. I also like this one because it has arial roots. It also still growing new ones . The not so straight one on the left in the picture is a new root that hasn’t got the grey bark yet. Even on some branches there are new arial roots coming out. It’s said that tiger bark ficus trees grow arial roots very easy and eventually they will fuse with each other and the trunk. So now cleaned and wired a bit it’s ready to spent the winter in my living room. (Were even I struggle to survive myself 😉 )
