Azalea Overview

Azaleas make a beautiful addition to any garden, with bushes covered in blooms, that come in various colours, from late winter until early summer. In autumn, the leaves become vibrantly multicoloured. While fairly low maintenance, they should be pruned after blooming to shape the plants. Remove dead or diseased branches any time. They love to growin acid soil!

Common problems with Azalea

Azaleas can be attacked by scale insects. Spray a dormant oil spray on branches in late winter before the flowers emerge to kill overwintering insect eggs. Powdery mildew may need to be controlled in years with hot, humid summers.

How to harvest Azalea

The flowers can be harvested and used as cut flowers.

How to propagate Azalea

Azalea semi-hardwood cuttings are taken with a heel and wounded to encourage rooting.

Layering

Seed

Sow into pots in spring, leave seed uncovered on the surface of the compost or top off the pots with a 2cm layer of damp perlite, scatter the seed over the perlite and ‘plough’ in using a pencil.
