The only way to keep them in pots is to use bonsai techniques, and it's a bit late for these, I'm afraid. I'm also not seeing the white growth that you are talking about, Zara. Can you set your camera on Macro, and show us a close-up?

The trouble is, these trees don't do well in pots for very long - they want to get up to about 15m high, so become stunted and rather sick if kept in pots ongoing. They really need to go into the ground I'm afraid.
