How Long Do Olive Trees Live?

Olive trees are among the longest-living cultivated plants in the world. Their resilience, ability to regenerate, and symbolic connection to longevity have made them a staple across Mediterranean landscapes for thousands of years. Australian growers often ask how long these trees can survive and remain productive — the answer may surprise you.

Most olive trees, when properly cared for, can live for several centuries. In fact, many ancient groves in Greece, Italy, and the Middle East still contain trees estimated to be over 1,000 years old. There are even heritage specimens believed to be 2,000–3,000 years old, still producing fruit today. In Australia, with good growing conditions and protection from pests and disease, olive trees can comfortably live for 300–500 years and continue bearing olives for oil and table use across multiple generations.

Even when the trunk becomes hollow with age, olive trees have a remarkable ability to regenerate from the base and produce new shoots. This regenerative quality ensures that, with proper pruning and nutrition, they remain functional in both backyard gardens and commercial groves.

Why Olive Trees Live So Long

Several unique biological traits give olive trees their legendary lifespan:

Regenerative Growth: Even after fire, drought, or severe pruning, new shoots emerge from the base and roots, keeping the tree alive.
Hardwood Durability: The dense, slow-growing wood resists decay, allowing trunks to survive for centuries even when hollowed.
Drought Resistance: Their deep roots and waxy leaves help them endure dry climates like those in Australia.
Longevity of Productivity: Unlike many fruit trees, olive trees can bear usable fruit for centuries, making them both ornamental and agricultural assets.

Nutrition plays an important role in extending a tree’s productive life. Consistent fertilisation with Complete Grow NPK 20-20-20 provides the nitrogen, phosphorus, and potassium required for balanced growth, fruiting, and resilience against environmental stress. Feeding in spring and late summer helps keep trees vigorous even as they age.

FAQs About Olive Tree Lifespan

How long do olive trees live in Australia? With the right care, Australian olive trees can live 300–500 years and continue fruiting throughout their life cycle.

Do olive trees stop producing fruit as they age? No — older olive trees often remain productive for centuries. With pruning and fertilisation, fruit quality and yield can be maintained even as the trunk becomes gnarled or hollow.

What’s the oldest olive tree in the world? Some of the world’s oldest living olive trees are in Crete and the Middle East, estimated to be over 2,000 years old and still bearing fruit.

How do I keep my olive tree healthy long-term? Use balanced fertilisers like Complete Grow 20-20-20, prune to maintain airflow, and water consistently during hot Australian summers. These practices help prolong life and maintain fruiting capacity.
