    Hi everyone, this is my first posting and I hope it's not too long winded.

    My question is... I have a sick Rhododendron (White) which has lost most of it's leaves and the buds turned brown and did not bloom this spring. Those leaves still there are yellow or light green rather than the deep green of the other healthy plants that complete the hedge. These plants are well established and are about 12 ft high. It is also now noticeable that the adjacent plant on the left is starting to show yellow in the foliage, although it did flower this year. These sick plants are in the centre of the Rhododendron hedge which is otherwise healthy and bloomed abundantly this spring. In March, I did fertilize with Rodo fertilizer as recomended by the local garden centre. Since I am a recent transplant from Ontario, and have no knowladge of the care of these species I would love some help.

    Bob

    What page, Chris?

    If it were here in North Carolina, I'd bet it is root rot.

    Take a soil sample and plant sample to your local Agricultural Agent. They'll analyze it for you and identify diseases, assalents, and nutrient deficiencies.

    In NC, the soil sample analysis is free, but the plant analysis cost $10.
