Sagerezia - Sageretia


GeneralitŠ°


small evergreen shrub from China, with small light green oval leaves, white or pinkish flowers in summer and purple fruits in autumn; the bark is brown and shows reddish spots where it is peeled. Always very used as bonsai in China, even in Europe it is much appreciated, especially for its rapid growth and very small leaves; it is not a bonsai very suitable for beginners, because bad climatic or humidity conditions cause a rapid desiccation of the leaves, moreover it is often attacked by pests and diseases.

Pruning


it is pruned throughout the year, given its great production of new branches; it thickens top, leaving two shoots of leaves to the shoots. This plant does not fear even drastic pruning, however it is advisable to cover the most extensive wounds with healing mastic.
It is possible to carry out bindings with wire throughout the year; both the sprouts and the already lignified branches lend themselves to being bound.

Exposure


like very bright places, but not direct sunlight. In spring and summer it is advisable to put it outside, taking care to shade it on particularly hot days, to avoid burning the leaves. Do not expose it to places that are too windy. In winter it should be sheltered in a cold greenhouse or at home, because it does not tolerate temperatures below 10 ° C.

Watering and soil


Watering: it requires large quantities of water, but without leaving the soil too wet. In the hottest periods, and even in winter if we keep it in a warm place, it is good to vaporize the leaves with water, to increase humidity. From March to October it is advisable to supply fertilizer for bonsai every 15-20 days.
Soil: it can be potted in a common bonsai soil; we can prepare an ideal soil by mixing two parts of peat, two parts of sand and a part of clay. Repotting takes place every two years or so, pruning the roots for about a third of their length.

Sagerezia - Sageretia: Multiplication and diseases


Multiplication: by seed. It is also possible to propagate by cuttings, taking 6-7 cm cuttings from the plant in spring; they are buried in a mixture of peat and sand in equal parts, after having sprinkled them with rooting hormone and kept in a sheltered and moist place, at a mild temperature (15-20 ° C). The following spring can be transferred to jars.
Pests and diseases: it fears root rot if the soil is kept too wet. Sometimes the scale insects nest under the bark, and the whiteflies under the younger leaves.
