What is causing my azalea to decline?
My azalea Molis has been in the same location for 25 years. It has done well with blossoms every year - some years more prolific than others. However, this spring it has several bare branches with few leaves and fewer blossoms. In these 25 years, I have never done anything to it - no pruning, no fertilizing. Does it need to be fertilized or transplanted?
It was most likely caused be or lack of snow cover last winter. We are getting many calls due to winter stress/kill. Prune out any dead branches and perhaps next year will be better. check http://www.gardeningknowhow.com/ornamental/shrubs/azalea/common-azalea-problems.htm for more information on azalea problems.
Good luck and have a great summer!
