Growing for the fruit might not be at the top of your list so if the silvery green foliage is what you are looking for, then Olive El Greco will be a perfect tree for you. The small section urban gardener will enjoy the compact mature size of this tidy variety. Best used as a specimen or hedging as it is not known to fruit in New Zealand, growing to a height and width of 3m x 3m.
Plant in full sun, olive trees show a marked preference for soils that are free draining soil with reasonable moisture retention. They tolerate drought well, thanks to their sturdy and extensive root system. Olive trees can be exceptionally long-lived, up to several centuries, and can remain productive for as long, provided they are pruned correctly and regularly. Spread the roots when planting as they are relatively shallow and would benefit from this.
Shelter is important so that trees can establish well and do not damage as they mature, they have a shallow root system. Some air movement is needed for pollination as well as to dissipate frost pockets during winter.
