Common Name: Olive

Botanical name: Olea europaea

Summary

An extremely hardy and long lived evergreen tree that is generally kept small for ease of cultivation, but can be utilised as a shade tree, screen, hedge or even topiary.

 

Originally cultivated around 4000 BC in the Eastern Mediterranean with trade making it a staple food right across the Mediterranean by 2000 BC.

 

Large tired trees can be drastically cut back to promote rejuvenated growth, however care should be taken to reduce sun scald on exposed old wood.

Care

Planting

Free draining soil, avoiding the hot times of the year.

Pollination

Partially self-fertile but cross pollination with another tree is advised.

Pruning

Train to an open vase shape, removing over vigorous growth and keeping the centre open to sun shine. Fruiting on last season’s wood, regular clipping after harvest will promote new fruiting wood.

Disease and pest management

Olive scale, treat as per any other scale insect; white oil etc.

Moisture

Highly drought tolerant but will perform better with supplementary water during flowering, fruit set and as fruit ripen.

Feeding

High nitrogen NPK in autumn and spring.

Harvesting

Olives for oil are left until fully ripe and black. Table olives are picked a little earlier when still a little yellow/green.
