Fertilizer and nutrient for azalea planting.

Fertilizer and nutrient for azalea planting.

    Textbook said Azalea often did not have problems if grow on the soil full with nutrient planting soil (Soil with lot of humus, many people use of the fertile top soil for planting Azalea or Rhododendron).

From my experience good way to planting azalea  is soluble fertilizer Osmocote 3-6 month slow the case may be. There's the use fertilizers such as 16-16-16 or 24-24-24 formula for azalea in sometimes, but about 2-3 years ago they tried to use microbial fermentation with compost and manure with azalea they work great as well.

      Azalea is often a problem of iron deficiency. This will cause problems with yellow leaves around the vein vein, but still green  in azalea  (Interveinal Chlorosis).

This will affect the growth of the Azalea and may cause death (From the experience this problem often die in the end.)

       This issue is resolved by using ferrous sulfate spray or watering azalea.

Problems of the chloro cis and never will solve the problem by using ferrous sulfate so can not say that due to iron deficiency or not. Or from other causes.

However, azalea textbooks have said that this condition may occur for several reasons. May be caused by flooding azalea. Soil too tightly. Or absence of other metals, etc.

      The textbooks say that Aluminium is a toxic chemical for Azalea So any chemicals that contains Aluminium should be avoided in the Azalea adoption is strictly prohibited.
