Egyptian Thorn Bonsai should be kept in a very bright position with as much direct sunlight as possible. In the UK climate it is best grown as an indoor bonsai, ideally placed near a south-facing window where it can receive strong natural light throughout the day. During warm summer months it may be placed outdoors in a sheltered sunny spot, but it should be brought back indoors before temperatures fall below around 12 °C.

Water regularly during the growing season, keeping the soil slightly moist but never waterlogged. Allow the surface of the soil to begin drying between waterings. Egyptian Thorn tolerates short dry periods better than constantly wet soil, so good drainage is important.

Feed every two weeks during spring and summer using a balanced liquid bonsai fertiliser. Reduce feeding during autumn and winter when growth naturally slows. We would recommend the Naruko Slow Release Feed.

This species grows quickly in warm conditions and responds well to regular trimming. Pinch back new shoots to maintain shape and encourage dense branching. Branches can be wired when young and flexible, though care should be taken due to the plant’s sharp thorns.

We recommend using wires with a thickness that matches the thickness of the branch: if the wire you choose is too thick, you will damage the bark. If it is too thin, it won’t be effective.

Repot every two to three years in spring using a free-draining bonsai soil mix. Trim the roots moderately during repotting to maintain a compact root system and encourage healthy new growth.

Trees that are ready for repotting will require root pruning, a suitable new pot and appropriate soil mix.

When repotting, do not cut back the root mass by a large amount, and choose a well-draining soil mix that has a neutral or slightly higher PH value of 5-6 but not over 7. We tend to use a mixture of different speciality bonsai soils on our trees. Every species is different so please contact us for free soil-mix advice or to take advantage of our repotting service.
