Pruning

Beginning in the spring, until the beginning of autumn, the shoots are trimmed, leaving them to grow several centimeters before cutting them, leaving 2-3 pairs of leaves. Usually the metal wire is not applied, except in cases where it is strictly necessary, but the crown tends to form with appropriate pruning.

Watering and soil


Watering: it likes a constant humidity, it must therefore be watered moderately but often, leaving the soil to dry a little between one watering and another. It tolerates short periods of drought well enough, it fears water stagnation. During the vegetative season, add fertilizer for bonsai every 15 days to the water used for watering.
Soil: the elm prefers clayey but well-drained soils, prepare a compost by mixing a part of peat, a part of sand and three parts of clay. If it does not present particular growth problems, it is repotted every 2-3 years, in late winter, just before the beginning of the vegetative season.
