First post - and first question!
I have (I think) - a Chinese Elm Bonsai - it has a leaf structure like this:
Anyway - recently (over the last few weeks), it has started to develop a few yellow leaves.
I'm in the UK - the current climate is quite mild. The tree is in a house with central heating, lots of light etc.
It's been watered every few days - soaked the root ball etc.
Any ideas what could be causing it? Over / Under watering?
