With olive branches the Olympians were crowned – the ivory statue of Zeus at Olympia, the work of Pheidias, one of the seven wonders of the ancient world, was also crowned with olive branches. The olive was the symbol of Greece in antiquity and olive oil was used not only for its nutritional values but also for medical purposes.

For humans, the most important and familiar species is by far the olive (Olea europaea).

Greek olive tree: Soil & Altitude

Olea can be grown in any soil type, even in stony, barren or saline soils, as long as they have sufficient drainage. However, higher yields are observed in fertile, medium sandy loam soils that retain moisture and have a depth of 1 – 1.5m.
The olive can be planted in lowland, coastal, semi-mountainous and mountainous (up to 1000m altitude for some varieties) areas of Southern areas, while in Northern areas its cultivation is limited to coastal areas.

Greek oil tree: planting season

Potted or bagged olive trees and saplings are planted all year round for amateur crops but avoiding periods of extreme climatic conditions. Potted olive saplings or trees intended for professional olive groves are planted all year round, also avoiding periods of extreme climatic conditions and provided the olive grove is irrigated.

Greek olive tree planting

For the creation of professional olive groves from olive seedlings in a bag, the planting takes place from November to the end of May, taking into account the special climatic conditions of each region and period. If the area is not affected by frost, the olives are planted in autumn. Otherwise they are planted in the spring.

The olive when planted in a pot in the yard or on the balcony requires a bright place, better semi-shaded protected from wind and frost. If we want to place it indoors, we must provide it with a bright place, with good ventilation, away from radiators, from cold and hot currents, as well as from windows.

Watering of young olive trees takes place every 3-7 days throughout the growing season. The water needs of young trees amount to 5-10lt / day and tree in the first year, 7-20 lt / day and tree in the second year and 15-40lt / day and tree in the third year. The water needs of a productive olive grove with 10-30 trees per acre amount to 300-400 m3 per year and acre, a quantity that depends on and varies depending on the variety, evaporation, location, soil and microclimate of the area where it has the olive grove is installed.
