Azaleas
The royalties of the garden
(xiangsi shu)



Due to their great variety and diversity brighten them in the spring to any garden with their striking colors and patterns. They rightly deserve the name "Royalty".
They are among the rhododendrons, but are still divided into a separate group.
Group A: evergreen azaleas (azalea japonica hybrids divided into several groups.)
Group B: the deciduous azaleas (. Which then further be divided into a number of groups) some species in a beautiful autumn leaf color, they lose all of their leaves in the fall.
Group C: Azalea indicum (not hardy type / room azalea)




Azaleas are generally easy plant as it met certain conditions.
As with Rhododendrons and Camellias require them humus rich and well drained soil with a low pH (4.5 - 6.5).
They are generally happy in a slightly damp / semi-shady spot.
Sufficient light and a few hours of sun is necessary for a good flowering.
In full sun they bloom richer, but shorter. Here particular attention to the humidity, never let dry out a azalea (this is pernicious)!
An at-fertilization in the spring after flowering, with compost or good azalea fertilizer, the plant will benefit a firm outgrowth.




Mulch after the frost in March, either in the fall (extra protection against frost). This is beneficial to the plant with regard to the water-management.
The root ball dries more quickly, and also draws additional power from the mulch layer. Please note, that the layer is not too thick, this causes nitrogen deficiency. (You can tell from the leaves becoming yellow).
The mulch layer removes nitrogen from the soil due. the digestion process. A little blue grain is to prevent, and preferably this June.
Deciduous azaleas are then happily consumed a good layer of compost on their feet.
If your azaleas manure, do it around the druiplijn of the leaves (see rhododendrons etc.) so as to prevent burning of the above-lying roots.
Water well to fertilize a dry spell.
