I have two azaleas, one white and other pink, and they are very green! New leaf every day. I give them plant food - Miracle Gro every 7 days, but no flowers! What is wrong?

They may be getting too much nitrogen and not enough phosphorus. Nitrogen makes healthy green plants and leaves, but too much blocks blooming. Use a fertilizer higher in phosphorus or even a phosphorus only amendment, like bone meal, to get them to bloom.
