Andromeda Have Healthy Foliage But No Flowers

Question From: L. Riley - Mendham, New Jersey, United States
Q: I have three Andromeda in one garden about 6' apart. one bloomed last year and this year and the other 2 did not. when they were purchased in 2013 all were in bloom. the foliage is very healthy but no flowers. I have not fertilized them.

A: Could be a combination of winter kill and lack of sun. The two that didn't flower may not be getting the sun the other one does. Pruning at the wrong time can also do it. Those are my best guesses. Best And Happy Yardening, Nancy
