Pruning: crown formation pruning is generally done in autumn, or at the end of winter; throughout the vegetative period, from March to September, the shoots are pinched: after they have produced at least 4-5 leaves they are cut leaving one or two leaves. In the same period you can set the branches using the metal wire.
Display: the ash is an outdoor bonsai, which does not fear the cold, although it is advisable to repair the plants in the coldest months of the year, using non-woven fabric. Place the pot in a sunny place, or in partial shade, taking care to shade the plant from late spring to summer, to avoid excessive insolation. Watering: water regularly from March to September, allowing the soil to dry up almost completely between one watering and the other; in the hottest months of the year it is good to remember to water often, to prevent the earthen bread from drying out excessively.
