Gardeners' Notes:

regardles of what veriety your rhododendron is, the all need acidic, loose and light soil. they will not grow in clay, waterlogged soil that is not acidic. your best bet is to plant it in peat and fertilize it with an acidic fertilizer every few months. here in central ohio, i have tryed to grow rhododendrons without experience... most failed until i planted it in peat, and when i was forced to transplant it within a few months, the roots had extended twice the size of the original rootball. i also bought 3 more large rhododendrons to replace the old ugly burning bushes that i tore out, and replicated the process noted above, i cant wait to see what it looks like come spring, it might be extra work, but its well worth it:)

This is the most widely grown of all Rhododendron. Adaptable to a wide range of conditions, it is the one to try if attempts at growing other Rhododendrons have been less than successful.

It could be anything nanabest, like bugs, (Black Vine Weevil make lunch out of mine), winterburn, drying out, etc. Can you post a photo of the damage?
