Azaleas, Camellias and Rhododendron are easy to grow when planted in the right USDA Zone, the right exposure to sunlight, the right soil, and proper fertilization. Though some varieties will tolerate full sun, for peak performance, most prefer afternoon shade, particularly in the hotter regions of the South. Moist, but well-drained soil is a must. Azaleas, camellias and rhododendrons will not tolerate wet feet. Humus-rich, fertile soil is preferred.
Fertilizing Azaleas, Camellias and Rhododendrons
At time of planting, make sure to mix an organic soil ammendment, such as Mushroom Compost or Composted Cow Manure, at a 50/50 ratio with the soil removed from the planting hole. This will help to get your plants off to a good start by stimulating root growth.
WHEN TO FERTILIZE: During the first Spring, fertilize your azaleas, camellias and rhododendrons just as the buds start to pop some color. Fertilize again, if needed, lightly in late Summer, but no later than 2 months prior to the first frost in your area.
NOTE: Fertilize Encore Azalea varieties after every bloom cycle to encourage a flush of new growth and flower buds...and then blooms!
WHAT TO FERTILIZE WITH: Fertilize with an Azalea, Camellia & Rhododendron fertilizer or a natural or organic fertilizer. These are acid-loving plants so make sure to use a fertilizer with a 'nutrient package' containing special extra-added nutrients such as iron. Avoid using fertilizers with high amounts of nitrogen (the first number in fertilizer) and phosphorous (the middle number). Always apply fertilizers at the rate suggested on product label.
Note: If the foliage on your plants turns yellowish-green to yellow, this could be an indicator of iron deficiency. Before applying iron, check to make sure that the yellowing foliage is not a result of oversaturated soil, or insect infestation. Certain insects, such as lacebugs, can suck the chlorophy out of leaves, causing a yellowing effect. If you are unsure as to what is causing the yellowing of leaves snip off a branch with some leaves attached and take it to your independent local nursery and garden center. An experienced professional there should be able to diagnose the problem and offer recommendations for a remedy.
