Growing Rhododendrons and Azaleas in Ohio
The elegance and beauty of azaleas and rhododendrons in bloom at the
nursery have caused many an unsuspecting gardener to purchase these
plants on impulse without knowledge of their cultural requirements.
These plants are often planted in heavy Ohio clay soil, and the
gardener is puzzled as the plants languish, dying branch by branch
until they are only a shadow of their former beauty.
