I trim my azalea bushes waaaay back just after they finish blooming. I hack them down and by next year they will have grown another 10"! I feed feed feed all summer long. I think the deadline here in Texas for trimming is August. After that you will cut off forming flower buds.
Life is short, Break the rules, Forgive quickly, Kiss slowly, Love Truly, Laugh
uncontrollably, And never regret anything that made you Smile.
