How to Manage Pests

Pests in Gardens and Landscapes

Olive—Olea europaea*
Family Oleaceae (Olive family)

Plant identification

Olive trees are mostly evergreen trees that grow from 25 to 30 feet tall. Often multitrunked specimen trees can be found. Dwarf forms grow to 12 feet tall. Fruitless types are available. 'Swan Hill' is noted for little fruit and pollen. Fruiting types drop fruit, which will stain pavement and patios. The pollen is highly allergenic.

*Olives are sometimes considered to be invasive weeds.

Optimum conditions for growth

Olive trees can grow in several climatic zones. They do best in full sun. They prefer little water once established. They are not tolerant of saturated soils or lawn conditions.
