Will rhododendrons and azaleas grow in clay soil?


Not happily, they won't. Have you ever walked through the kind of forest
where your feet sink 6" into the amazing leaf mold that lies on top of soil
that's moist & fluffy? That's their favorite environment. Both things
contribute to this - the leaf mold *and* the soil underneath, so just piling
leaves on top of clay soil won't do the trick, at least not in the short
term. If you want to grow these things, you'll need to improve the clay
soil, which can take 2-3 years if you really work at it, or forever if you
make a half-hearted effort.
