Azalea

The wide genus Rhododendron includes hundreds of bloom shrub species, among the most spectacular, which have originated thousands of cultivars. Many species are native to Japan and, since 17th century, Japanese people have propagated and crossed them. The most common bonsai species are evergreen "Satsuki" Azaleas: some Japanese growers cultivate only these varieties. Contrary to most Azaleas, which flower in late spring, "Satsuki" ones bloom in summer. In second place among bonsai growers' favorite varieties there are "Kurume" specimens, originated from Rhododendron kiusianum.

Half light. Shelter it from frost and, when it is in flower, also from heavy rain.

At least once a day during the vegetative season, sprinkling the leaves. Use little calcareous water. Rain water would be ideal. Water it less frequently in winter, but keep the soil constantly wet: the thin fibrous roots dehydrate easily.

In spring fertilize it every two weeks until blossom time, then once a month until the beginning of autumn. Use fertilizers suitable just for specimens liking acid soils.

Every year just after the withering of flowers or according to the needs of the root-ball. Use mould without limestone; all Azaleas need no calcareous soils.

After the fall of the flowers remove all the new buds. Prune slightly the minor sprouts until mid-summer. Remove carefully every withered flower.

By semi-wooden cuttings or by layers at the beginning of summer.

Suitable for all styles, apart from Bloom style, and for all sizes. Varieties with small leaves and flowers are better for little bonsai specimens.
