People often ask us this at Olive Grove Oundle, since we sell more olive trees than anyone else in the UK. We’re just as interested in the answer as you are, though: no one really knows how long olive trees can live. We have an idea of how old the oldest trees are, but we don’t know how much longer they’ll live. Olive trees are truly amazing things in nature!
With their gnarled trunks and silvery green foliage olive trees have an ancient, timeless quality about them. It’s not surprising that olive trees are one of the longest-living trees on Earth. The lifespans of these iconic trees are incredibly impressive.
Just how long can olive trees live? Some individual trees are estimated to be over 2,000 years old. Even the average lifespan is centuries longer than most other trees. Let’s explore why olive trees are such survivors and how they can thrive for millennia.
Maximum Lifespan – The Oldest Olive Trees
While it’s impossible to know exactly how long the oldest olive trees have lived, scientific estimates place some trees at over 4,000 years old. That’s older than the Parthenon! Here are two of the most ancient known olive trees:
-
The Al Badawi tree in Bethlehem is estimated to be between 4,000 – 5,000 years old. This would make it one of the oldest known living trees Local legend claims it has been producing fruit for over 5,700 years
-
On the Greek island of Crete the Vouves Olive Tree is thought to be at least 2,000 years old and possibly up to 4,000. Despite its great age, this tree still produces olives. Carbon dating verifies it is at least 2 millennia old.
Average Lifespan in Ideal Conditions
-
Under optimal growing conditions, olive trees typically live around 500 years on average.
-
Some research estimates place the average lifespan at closer to 700 years.
-
Olive trees grown for commercial fruit production are generally replaced after around 200 years for maximum yield. But the trees could continue living much longer.
-
Given ideal care and climate, olive trees seem capable of living indefinitely, like the ancient specimens above.
Why Do Olive Trees Live So Long?
Several key characteristics enable olive trees to survive for centuries:
-
Tolerate drought – Olive trees are adapted to drought and can withstand long periods with little rainfall due to their thick, waxy leaves that minimize moisture loss.
-
Resist fire – The olive tree’s gnarled trunk is covered with insulating, fire-resistant bark that protects it from heat damage.
-
Grow back when damaged – If the main trunk becomes damaged or diseased, new shoots sprout from the extensive root system. This essentially restarts the tree.
-
No natural defenses – Olive trees produce no toxins or substances that would limit their lifespan like other trees.
-
Coppice easily – Olive trees readily regenerate, sprouting new growth when pruned back close to the ground or the roots.
-
Genetic diversity – High genetic diversity provides resistance to diseases over centuries.
Thanks to these adaptations, olive trees handily outlive nearly every other tree species given the proper climate and care.
Growing Conditions for Maximum Olive Tree Longevity
To reach their maximal lifespan potential, olive trees require:
-
Mediterranean climate – Warm weather with hot, dry summers and mild, rainy winters is ideal. Olive trees thrive where temperatures reach over 100°F (38°C) in summer. They can survive light freezes in winter.
-
Full sun – Olive trees need a minimum of 6-8 hours of direct sunlight daily. More sun is better.
-
Well-drained soil – Excellent drainage is crucial to avoid root rot. Sandy or rocky soil is preferred.
-
Limited fertilization – Olive trees are adapted to poor soil and grow well without nutrient-rich soil amendments. Too much fertilizer can damage olive trees.
-
Pruning – Regular pruning of older wood rejuvenates olive trees and supports longevity.
With the right climate and care, olive trees seem capable of living indefinitely. The oldest trees provide ample proof of their potential for millennia-long life spans.
Why Olive Trees Have Been Cultivated for Thousands of Yearss have cultivated olive trees since ancient times, and for good reason. Olive trees offer several benefits that have sustained civilizations through the ages:
Fruit Production
-
The olive fruit is highly nutritious and rich in healthy fats and antioxidants. Olives can be eaten fresh or cured into edible olives.
-
Olive oil was historically vital for cooking, medicine, lamplight, and religious rituals. Today, olive oil is prized for its flavor and potential health benefits.
Wood
-
Olive wood is dense, carvable, and beautifully grained. It has been used for sculpture, tools, and construction since antiquity.
-
The wood burns slowly and gives off pleasant scents, making it ideal for heating and cooking fires.
Landscape Uses
-
Olive groves and orchards help prevent soil erosion on hillsides. The extensive root systems stabilize terrain.
-
The trees provide pleasant shade in hot climates. Their reflective foliage helps cool landscapes.
-
The attractive appearance and symbolic history of olive trees make them valued landscape elements.
Olive trees have sustained and enhanced human civilization in the Mediterranean region since the beginnings of recorded history.
Notable Ancient Olive Trees
Some individual ancient olive trees have special historical and cultural significance:
-
The Olive Tree of Vouves in Crete is thought to have been producing olives when the ancient Minoan civilization thrived on the island.
-
Tunisia is home to the Olive Tree of Sfax, estimated to be over 2,000 years old. It still bears fruit.
-
Bethlehem’s ancient Al Badawi olive tree is a revered religious site where the Bible records Jesus praying before his crucifixion.
-
The 1,600 year old Sarandë Olive in Albania is considered a national monument.
-
In France, the Olive Tree of Roquebrune is said to be the oldest tree in the country, around 1,500 years old.
These living legacies give just a glimpse into the extraordinary longevity of olive trees.
Caring for Olive Trees to Maximize Lifespan
To help your olive trees reach their maximum potential lifespan:
-
Select disease-resistant cultivars suitable for your climate.
-
Plant in well-drained, slightly alkaline soil in full sun.
-
Water deeply but infrequently, allowing the soil to dry between waterings.
-
Fertilize lightly in spring with an organic fertilizer. Avoid excessive nutrients.
-
Prune annually to stimulate new growth. Remove any dead or diseased wood.
-
Protect trees from severe cold and frost with coverings or plantings on south sides.
-
Harvest olives carefully by hand, not beating branches with sticks which can damage trees.
With attentive care, even relatively young olive trees may continue thriving through generations to come.
The impressive longevity of olive trees is a testament to their resilience and adaptability. Given the proper climate and care, olive trees can live and bear fruit for thousands of years, earning them a cherished place in many cultures. Their great age only adds to their mystique and appeal. With attention to their basic needs, olive trees planted today may still be producing olives hundreds or even thousands of years in the future.
How old are the oldest olive trees?
What’s believed to be the world’s oldest olive is located in Bethlehem. Nicknamed Al Badawi (meaning ‘the big one’), researchers who’ve analysed it reckon it’s somewhere between 4 and 5,000 years old – yes, really. How much longer it will live for is unknown, but it’s still going strong as you read this.
It’s not the only ancient example of the species, either. There’s another remarkable tree located on the Greek island of Crete. Based on a ring analysis, the Vouves olive tree is at least 2,000 years old and is still making olives. However, people in the area think the tree is much older; they think it may have been there for 4,000 years!
What is the average lifespan of an olive tree?
These aren’t your average olive trees – but even more ‘regular’ examples often live for hundreds of years. It’s estimated that the average lifespan of an olive tree is approximately 500 years.

How long do olive trees live?
The complete life cycle of an olive tree includes germination, seedling growth, maturity, and a long period of fruit-bearing before eventual decline. While olive trees can live for hundreds, even thousands of years, their productivity peaks between 35 and 150 years. Beyond this, they may still bear fruit, but the yield gradually decreases.
How long do olive trees take to grow?
Olive trees have been cultivated for over 6,000 years across the Mediterranean region. Depending on the variety and growing conditions, these trees can begin producing fruit within 3 to 12 years of planting. In this article, we will explore the fascinating life cycle of olive trees, delving into the stages from seed germination to ancient maturity.
How much fruit does an olive tree produce a year?
Generally, a smaller olive tree might produce around 30 to 40 pounds of fruit per year. While that same tree after it has matured can produce up to 100 pounds of fruit per year! There are high-yielding varieties, however, that can produce a far larger harvest.
