Stewartia

Stewartia

Native to Japan, Stewartia has aroused a growing interest as bonsai in recent years. The beautiful glittering copper bark and the delicate clear branches would be sufficient reasons for its cultivation, but we have to add the autumn show of the foliage verging on scarlet and purple nuances. Stewartia is a little plant genus, similar to Camellias, which do not bear calcareous soils. The dwarf form Stewartia monodelpha is, together with S. pseudocamellia, the favourite species for bonsai growing. Because of their trunk and bark quality, the bonsai specimens are at their best in winter, when they have no leaves.

Exposure
Exposure
 

In summer, half light. In autumn expose it to sunlight to improve leave colour. Shelter it in winter.

 

Watering
Watering
 

Everyday during the vegetative season. Use just sweet water (without limestone contents): rain water would be ideal. Water it less frequently in winter, keeping the soil uniformly wet: like other thin leave plants of the Heather family, it suffers dry soil and the leaves wither quickly.

 

Fertilizing
Fertilizing
 

Every two weeks, during the vegetative season; use just the proper fertilizer for this kind of plants.

 

Repotting
Repotting
 

In alternate years at the beginning of spring, in no calcareous soil.

 

Pruning

Pinch constantly the new shoots to 1-2 leaves, using your fingers, except when the growth is necessary to the whole shape development. If you use metallic wire, take into consideration that the tender wood can easily suffer damage.
