This Rhododendron is not looking so good - gradual leaf death happening from the bottom up. Doesn't really look like normal annual leaf loss to me, although the buds look promising. And when I cut off a few scraggly stems, they were green inside so don't seem to be dead. I haven't done anything to this plant except bring it home last fall from the nursery, so my legendary plant "care" is not to blame. But although the plant is a good size for its two gal container, the roots did not extend beyond the top half when I pulled it out of the pot yesterday. I'm wondering whether these symptoms are suggestive enough of phytophthora that I should isolate the plant and sterilize my tools! By the way it is a purple-leaved variety that is just greening up after being purple in winter, so the top-most leaves do look healthy, not browning.
