|Two Rhododendrons I planted in July 96 have a large number of leaves which are turning yellow and dropping off. They are not the top leaves but toward the bottom. The plants have been fed (with fertilizer for acid loving plants) and watered regularly. This is not occuring as heavily on other Rhododendrons planted at the same time. Is there anything I can do to stop this?|
|Yellowing leaves is a pretty general description, so it will be hard to come up with a definitive reason for your problem. You didn't mention holes, mildew, or curling, wilting leaves; are any of these symptoms present?
Have you fed and watered these rhodies any more or less than their garden mates? Lack of water is probably the most common problem with newly-planted shrubs and trees. Also, I wonder if the soil they are planted in is not of the same quality as the others that are thriving.
You might want to have the soil from around your struggling plants tested. You can contact your local Extension Office (ph# 603/673-2510) for test kits. Explain the problem, and they may be able to suggest some amendments.
