Azaleas with yellow leaves

Asked December 1, 2018, 1:02 PM EST

Hi, Could you please help me diagnose why are these azaleas getting yellow leaves? Is this something adversely affecting the health of the plant? If so, what to do about it? Many thanks in advance!

WE do not see disease or insect evidence.

The leaves of some azalea varieties often turn purple, red or yellow in the winter. Another possibility would be a lack of iron. You can apply a liquid fertilizer, such as Miracid.

The soil may also be too alkaline. You may want to have a soil test done for that shrub bed. (Search 'soil testing' on our website.)
