Differences Between 34-10-10 And 3-4-3 Fertilizer

Q: What is the difference between Azalea, Camellia, Rhododendron fertilizer
(34-10-10) and Azalea, Camellia, Rhododendron fertilizer (3-4-3)? 

A: As you know, fertilizer products are made by mixing different chemicals
together. These chemicals supply the nitrogen, phosphorus, and potassium that
plants need. Some chemicals dissolve in water quickly, so they are
immediately available for roots to suck up and feed the plant. Others dissolve
slowly and last longer in the soil. Generally speaking, any fertilizer product

with numbers above 6 is a fast-dissolving fertilizer, although some fast-
dissolving fertilizers are coated to slow down the process. A product with

numbers of 6 and below is typically made from organic materials that dissolve
slowly. Many gardeners note that the slow-release products contain lots of
micronutrients (calcium, iron, magnesium,etc) that fast-release products do
not have.
