Use
In relation to climatic conditions, it is widely appreciated as a bonsai species in:
Outdoor ornamental environment Indoor ornamental environment
Hardiness
Of medium to high hardiness, it is an indoor plant in cold climates but does not require too high temperatures indoors, but rather excellent light. It adapts well to hot summer climates.
Soil
Use a specific bonsai soil or prepare a mixture of 25% good porous component (sand, pumice, etc.), 50% clay component (akadama) and 25% peat-based soil.
Difficulty
It is an easy plant in terms of cultivation management and maintenance but, like all bonsai, it must be cared for very regularly.
Growing tips
Some specific cultivation tips for better vegetative development:
Expose the plant to maximum light Prefers warm, dry climate Shelter the plant indoors at temperatures below 12°C in good light conditions Correct pruning
Combinations with other plants
Prune regularly in order to shape the plant and maintain it. Pruning the Olive tree is always possible, letting new shoots grow regularly throughout the growing season and cutting back when they reach 6 pairs of leaves. Constantly remove suckers and suckers when they form.

Propagation
Multiplication can take place from seed and cuttings.
Repotting
Repotting should be done every two or three years in August, reducing the root system.
Watering
Water the pot not excessively but continuously during the growing season to allow for constant growth. Allow the substrate to dry between two successive waterings. Carefully avoid stagnation. Raise the pot to allow excess water to drain away.
Fertilising
Use specific slow-release organic fertilisers, of Japanese origin, with titres designed for bonsai. In this way the plant will take up the available elements independently when it needs them. Spread on the pot, under the foliage, lightly inserting the granules into the soil.
Autumn-winter fertilisation should always be done with an organic fertiliser, but less rich in nitrogen (e.g. Biogold classic) in order to avoid over-fertilisation.
Expert advice
Tip
Carefully avoid stagnation and allow the substrate to dry out between watering. Raise the pot to facilitate water drainage. Leave the plant in as much light as possible Prune regularly to shape the plant and maintain it.
