Recently I've began to notice some small white spots on the leaves of my bonsai. Is my bonsai getting sick?

And if so, how do I cure it? Thanks.
Alright, thanks for your help! Do you have any idea how scale is contracted?treeman wrote:Scale. Spray hort oil with a dash of malathion. The plant will change colour if you do this from blue green to bright green.
It will take a long time to get back to its normal colour again. If you don't want that you need to use a systemic at least three times over a month.
If you don't want to do that you can use soapy water and spray every week for ever.
