Azalia

Did you use ericaceous compost to pot it? Does it look healthy apart from not flowering?

Azelia's love acid and one of the best souces is a concrete foundation (concrete emits acid into the soil) AND coffee grounds. Starbucks gives bags of espresso grounds away free just for the asking.

Try using chunks of concrete in your large well drained pot and feed it the normal approiate fertilizers AND a regular treat of coffee grounds.

Then if it still doens't bloom, talk very nicely to it and explain that you simply don't have time for a difficult child and you WILL replace it with a more amicable plant who wants to bloom its flool head off!!!! LOLOL

Hope this helps
