Thanks guys, yeah, I had it inside last winter, took it outside a bit early (March, neighbour that gifted it just about died when he found that out upon returning from his winter away in May...but it made it-just purple leaves for a few months
.
Inside environment isn't tropical, cool room/reasonable humidity south facing with lots of windows (but lots of overcast/rain here in Vancouver). It grew a little last year thru winter but not much as I had it in a low light area and didn't feed it much either.
Can't be rootbound at all, early summer I exposed many roots just exploring nebari for pics higher up in this thread....I could repot without cutting any roots/just minor rearranging....neighbour had convinced me to buy a huge/oversize/pricey pot for this originally which creates indoor havoc as it's just too tall/too long etc to fit reasonably on any shelf and it's twice the weight it needs to be.
BTW, this ficus has huge leaves IMO, can't really see in my mind how this particular plant could be bonsai......it was in partial shade all spring/summer on my deck, in full sun will the leaves really be that much smaller? I like them the first 1-2 weeks......then too large. I've contemplated getting some indoor lights but haven't done any research on cost benefit etc of various methods. I don't have many indoor plants.
