The Frantoio olive tree grows well in milder climates, but it is not as tolerant of heat and cold as Spanish olive cultivars. This olive tree grows with moderate speed and has an airy, even wispy, canopy.
As a commercial producer, Frantoio tends to be highly productive in the right conditions and has a tendency to grow more like a tree than a bush, which is different from most olive trees. Average oil yield is 23-28% of the fruit. It is self-pollinating and is excellent for pollinating other cultivars. Self-pollinating, it can be used as a stand-alone specimen.
Mature fruit is purple-black, but at the preferred picking time, it is green and purple. Attractively, its rich in oil (between 17 and 22% of fruit) is very fruity, notably aromatic and of high quality, with a stronger aftertaste than Leccino.
Inconspicuous, white flowers; prized for evergreen foliage and its fall fruit.
Glossy, Dark Green Color
Can reach 20 to 25 ft. tall if given opportunity, 25 ft. wide canopy
Coastal Exposure, Mass Planting (high density), Orchard, also Container, good for Urban Areas.
USDA 8 – 11, Sunset 24
Hardy down 10 to 30 °F, more sensitive to heat and cold than other olive cultivars. Good in the northwest.
Full sun, tolerant of fog
Once established, water occasionally.
Water more frequently in extreme heat or containers. Newly planted olive trees will require more water to establish.
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.
Thrives in most average, slightly alkaline, well-drained soils, but it is adaptable. More productive when planted near another olive variety (partly self-pollinating), most commonly Leccino. Water deeply, regularly during first few growing seasons to establish an extensive root system, or if developed in container. Once established, reduce frequency; tolerates drought. Shelter young plants from winter extremes.
