Repotting bonsai out of season
I am new to bonsai and have a problem with my Zelkova. I think that it needs repotting as there are lots of little fine thread-like roots coming up from the soil. It only has about 10% leaves on it at the moment but new ones are still appearing. I suspect my poor watering technique is to blame - I must do better. It is late summer here so not really the time to repot but it looks in such poor condition that i'm not sure which will be the worst option; repotting out of season or leaving it for another few months. I'd be grateful for some advice.
