Therefore, western, northwestern or northern exposures are poor locations for these shrubs unless they are surrounded by other taller shrubs or trees. An eastern exposure is best. Southern exposure is adequate, but light shade may be needed in the summer. Deciduous azaleas can better tolerate the exposed locations, but even they benefit from at least some shelter. S oil requirements Generally, rhododendrons prefer an acidic soil rich in organic matter.
Most Newfoundland soils are naturally acidic.
Books may suggest you add sulphur to the ground to help increase acidity, but this is not needed or recommended in Newfoundland. The soil should retain moisture yet be well-drained. Rhododendrons and azaleas will not tolerate dry conditions. While rhododendrons do best in a peaty soil, peat is not required. Any moist loamy soil will do if it is acidic.
