Existing Bonsai A To Z Entry for Azalea (Rhododendron)


Azalea (Rhododendron)

 - (Tree Type (Outdoors))
Azalea (Rhododendron) - Bonsai Tree Type (Outdoors) Bonsai Care

Azaleas and rhododendrons are the same plant, both ericaceous (lime-hating), with thousands of cultivars. They are noted for the wide variety and vibrancy of colours of flowers which bloom mostly on "garden" specimens in mid-spring.

Most popular for bonsai are the Satsuki Azalea (Rhododendron Indicum) which are distinguished by often having multiple different coloured blooms on the same tree.

Also popular although less well recognised is the Kurume Azalea which is a hybrid of R. obtusum and R. kiusianum both native to the island of Kyushu, the southernmost island of Japan.

STYLE : Best in all sizes and all styles, except broom.

WARNING : Some fertilizers can be slightly alkaline so ensure truly ericaceous fertilizer only is used.
