I picked up this bonsai in May and it’s been doing good in my house but recently (last two weeks) it’s been dropping a lot of leaves and the branches are dry and brittle, there is some new growth and even some fruiting. The soil drys out quickly so I’m worried it’s root-bound. I’m in south Alabama in zone 8b. The bonsai is either Tigerbark, Ficus retusa, or Microcarpa at least that’s what I’ve been told. Does it need to be repoted is it the wrong time to report?
