For richer flowering and growth dead-head where possible. Rhododendrons are low-maintenance shrubs that will perform superbly provided you plant them well. They mostly prefer bright to dappled shade or partial shade (partial sun). Morning sunlight is their killer, same as deep shade. The roots are shallow, spreading to sides in search for nutrients. Never plant them too deep. The soil has to be acidic (pH 4.5-5.5), rich in humus, cool and always moist. Adult plants withstand direct mid-day and afternoon sun if their roots are always moist, they can even handle temporary water-logging. Ideal soil mixture is peat with lime-free, light garden soil topped with leaf-mould. Fertilizing is not recommended, however, you can always use a special flower encourager.
