I'm new here, I've got a Chinese Elm or Zelkova (I'm not sure which as I know there is a lot of confusion between the two). Its the one where it grows small little white flowers.
Leaves turning brown & dropping off
I've had it since February and not had any problems, it grew really well during the summer but now quite a few of the leaves have turned brown and dropped off. New ones have grown in place, I'm not really sure what's happening to it.
I read somewhere that they go dormant during the autumn/winter months but not sure if this is right and what I'd need to do?
I also don't know whether it needs re-potting. When I use a toothpick the roots seem to reaching the edge of the pot. When I bought it, the tree was quite unstable in its pot but its not now.
I water it with bottled water usually on average once a week but don't let it dry out and try not to overwater it. I've got it indoors and not moved its position or anything like that.
Please can someone advise what might be happening?
