Olea europea sylvestris - ULLASTRE - B4989

Sunlight: Prefers full sun. Direct sunlight promotes trunk development, foliage compactness, and more abundant flowering.

Watering: Tolerates dry periods, but in bonsai it should be watered regularly during the growing season, allowing the soil to dry slightly between waterings. Reduce watering considerably in winter.

Humidity: Adapts to various humidity levels, ideally moderate. Occasional misting can be done during hot months.

Pruning: Pruning is essential to control growth, encourage fine branching, and maintain aesthetic shape. Can be performed during the growing season, with structural pruning in late winter or early spring.

Fertilization: Feed from spring to autumn with a balanced fertiliser or one specific for olive trees. Suspend fertilisation in winter.

Repotting: Repot every 3–4 years, preferably in early spring, using a well-draining substrate (akadama, pumice, and sand mix).

Flowering and Fruiting: Produces small fragrant white flowers in spring, followed by small green fruits that ripen into dark olives. The main ornamental value lies in the twisted trunk and compact foliage.
