Koroneiki Olive Tree

Olea europaea ‘Koroneiki’ aka ‘Psilolia,’ ‘Lianolia,’ ‘Vacikior’ or ‘Korani’

After the Arbequina and Arbosana, Koroneiki olive trees are the most widely grown throughout Greece. With an open canopy and medium vigor, it is ideal for dense planting.

Koroneiki olive trees are the one of the primary varieties of Greece (nearly 50% of the country’s olive production) with well-recognized quality characteristics, very heavy fruit set, but very small fruit. Its oil is generally quite green in color, very fruity with an emphasis on herbal-green fruitiness. It has medium bitterness and pungency. But it is graced with a long shelf life of two or more years. From an economical point of view, it really can only be considered for planting if picked with some type of mechanical harvester.

Zones

USDA 8 – 11

Hardiness

Hardy down 20 to 30 °F, less tolerant of cold than other cultivars

Light

Full sun

Water

Once established, water occasionally.

Water more frequently in extreme heat. Newly planted olive trees will require more water to establish. This cultivar is resistant to water stress and wind.

Soil

Well-drained, nutrient poor soil

Light (sandy), medium (loamy) and heavy (clay) soils all acceptable. Olive trees prefer well-drained soil and even grow well in nutritionally poor soil. Hot, rocky locations. Suitable pH: acid, neutral and basic (alkaline) soils.

Care

Thrives in most average, slightly alkaline, well-drained soils, but it is highly adaptable. More productive when planted near another olive variety. Koroneikis are commonly planted in high density layout near other olive trees. Formation will depend upon mechanical harvester needs and specifications. Water deeply, regularly during first few growing seasons to establish an extensive root system. Once established, reduce frequency; tolerates drought. Shelter young plants from winter extremes.
