I was given this tree from old nursery stock a few months ago, it was heavily root bound and straight-up and down as you can see It had retained quite well over the winter (in comparison with some others I was given at the same time) but work needed to be done!

Now I know this isn't looking like the most appealing bonsai specimen but I need practice on other trees before I dive in and kill all the interesting ones!
Since it was covered with freshly opened buds, I thought this would be a good time to repot, so I got it out of it's pot, teased out the roots (where teased=ripped

The next day I pruned back some thick branches on the top to balance the amount of roots I chopped the day before, applying honey to the wounds and removed all of the old disfigured leaves, leaving the multitude of freshly opened buds and decent looking older leaves. BUT today I have noticed it isn't looking to healthy...I have kept the water up to it since the chop and out of extreme sun but the older leaves are turning slightly discoloured and now I'm worried...worried because I don't know enough about them to save it!
Maybe Pup or one of you excellent Melaleuca masters will have some ideas on where I've gone astray..too wet etc?
Or am I worried about nothing and it is simply the time for the old leaves to leave? (

Cheers for reading such a long post and bonus cheers from me if you can help me save this plant!
