Question: bonsai olive tree


They gave me a bonsai olive tree that after losing almost all the leaves starts to put on new ones. I placed it on the windowsill where the direct sun never beats but I don't know what else to do. How much to water it, when and how to fertilize it, when and how to prune it ... Thanks.

Answer: bonsai olive tree


Dear Cristina,
the olive tree is a tree to be grown in the garden, or in any case outdoors, even if it is a bonsai; if you live in an area of ‚Äč‚ÄčItaly characterized by very cold and / or wet winters you can still grow it outdoors, having the foresight to place it in an area well sheltered from the wind, and covering the pot and the plant with non-woven fabric, in so that it is not subject to frost. In fact, this cover can be positioned even for only a few weeks, just when the winter cold is more intense. When we buy a plant, be it bonsai, potted, or to be placed in the ground, and we do not know the cultivation method, we can simply consider where this tree lives in nature. The olive trees originate from the Mediterranean area, where they have been grown for millennia. So your bonsai will love similar conditions to Mediterranean ones, with hot summers, and mild winters.
Your plant has probably lost its foliage because you put it in the apartment, where the climate is definitely too dry for most plants; also in the nursery your bonsai enjoyed a cool and very humid climate, even if it was grown inside the greenhouses.
The fact that he is starting to produce leaves again, means that the moment of stress was only temporary, and did not cause serious damage to the plant; now to best cultivate your olive tree place it outdoors, in a place sheltered from the wind, with at least a few hours of direct sunlight. Since your bonsai has remained at home for some time, before placing it in the full sun, make some gradual movements, putting it first in an area where it has only a few hours of sunshine, during the coolest hours of the day. Olive trees are resistant and vigorous plants, with a very slow growth; they need watering to be provided only when the soil is dry, as they tolerate drought very well, but fear water stagnation; supply a fertilizer every 15-20 days, from March to September, mixed with the water of the watering, specific for bonsai.
Pruning is practiced all year round, shortening the shoots, leaving about 2-3 leaves; also the training prunings are practiced all year round, covering the wounds with mastic for pruning.
