RHODODENDRON
To assure good bud set, longer flower life and healthy, appealing foliage; grow in full morning sun with filtered sun or shade in the afternoon. A few varieties are considered sun tolerant and can be used in more exposed situations, but rhododendrons should generally be protected from hot mid-day sun. Grow in well-drained, humus-rich, acidic soil. Rhododendrons are surface rooting so do not plant too deep. The top of the root ball should be level with firmed soil. Water generously when first planted to establish firm roots. Avoid root-rot with thorough less frequent watering and by planting and by planting in raised beds or mounds especially where poorly drained soils are a problem - mulch roots when soil is exposed to direct sun. Feed with a commercial Rhododendron / Azalea fertilizer four times a year: 1st immediately after flowering, 2nd in six weeks, 3rd mid-summer, and 4th early autumn. Water thoroughly after feeding. Remove dead blossoms to encourage new growth.Â
CAMELLIA
Grown in well drained well-drained humus-rich, acidic soil, mulch in the summer and avoid over watering. Do not plant too deep, the top of the root ball should be level with firmed soil. Plant in sheltered area with partial or dappled sun. Use a balanced fertilizer in mid-spring again in early summer if necessary; do not overfeed. Camellias handle pruning well.
AZALEA
Growing conditions for azaleas are very similar to rhododendrons. Azaleas are best planted in groups or as a hedge. Refer to 'RHODODENDRON' for fertilizer, watering and sun tolerance suggestions.
