Olive trees (Olea europaea) are not evergreen. They are a deciduous tree species, meaning they shed their leaves seasonally. During the winter months, olive trees typically drop most of their foliage, only retaining a few leaves or stems.
As a botanist, I’ve always been fascinated by the notion that some plants are evergreen – retaining their foliage year-round, no matter the season.
But when it comes to olive trees, I’ve noticed that many people assume they fit this bill.
After all, doesn’t the fact that they still sport leaves in winter mean they’re truly evergreen?
Not quite.
In today’s post, we’re going to debunk the myth surrounding these Mediterranean staples and explore the surprising truth about their seasonality.
As someone who’s spent years studying the intricacies of plant growth and development, I’ve had the privilege of observing olive trees up close.
And let me tell you – they’re more remarkable than you might think.
From their explosive spring growth to their dormant winter period, olive trees have a seasonal pattern that’s both fascinating and challenging to navigate.
In this article, we’ll delve into the details of what makes olive trees tick, and provide practical tips for gardeners and landscapers looking to care for these incredible plants.

The Evergreen Myth Debunked
I’ve heard it before – “Olive trees are evergreen, they’re always producing new growth!” Well, let me tell you, that’s not entirely accurate.
In botanical terms, an evergreen is a plant that retains its foliage year-round and produces new growth continuously.
Sounds simple enough, right?
But here’s the thing: olive trees aren’t truly evergreen.
Now, before I dive into why, let me clarify what people often mean when they say olive trees are evergreen.
They’re thinking about how these gorgeous trees don’t completely drop their leaves like deciduous trees do in autumn.
And that’s true!
Olive trees do retain some foliage year-round, which can give the illusion that they’re always producing new growth.
But, my friends, appearances can be deceiving.
The truth is, olive trees are actually semi-evergreen or deciduous-dominant.
That might sound like a mouthful, but stick with me.
What it means is that while some of the leaves on an olive tree may remain green and functional year-round, many others will eventually senesce (get old and die) and fall off.
So, what happens during winter?
Well, that’s when things get really interesting.
You see, olive trees have a dormant period during which they essentially shut down their growth processes.
This is because the cooler temperatures and reduced sunlight can make it difficult for the tree to produce new growth.
And guess what?
It’s perfectly normal!
In fact, many plants in Mediterranean climates like where olive trees thrive go through a similar process.
Now, I know what you’re thinking: “But wait, my friend, if olive trees aren’t truly evergreen, then why do they seem to always have some greenery?” Ah, that’s the beauty of it!
Even though olive trees don’t meet the strict botanical definition of evergreen, they still manage to look fabulous year-round.
It’s all about adaptation and survival strategies.
Those senescent leaves might be old and tired, but they’re still doing their job by providing some level of protection for the tree during times when it can’t produce new growth.
So there you have it – the surprising truth about olive trees’ seasonality.
They might not be truly evergreen, but they’ve evolved to thrive in some pretty tough conditions.
And that’s what makes them so darn fascinating!
The Seasonal Pattern of Olive Trees
Are you an olive enthusiast?
Do you have a tree in your backyard or simply admire these majestic plants from afar?
Either way, today we’re diving into one of the most fascinating aspects of olive trees: their seasonal pattern.
Let me ask you, have you ever noticed how olive trees seem to burst forth with new life in the spring and summer months?
It’s as if they’re trying to make up for lost time!
In fact, a study I came across found that olive trees can grow an astonishing 30% of their total biomass in just three short months during the peak growing season.
That’s like me going from couch potato to marathon runner in the blink of an eye!
So, what’s behind this rapid growth?
Well, it all comes down to the unique characteristics of olive tree physiology.
You see, these trees are deciduous, meaning they shed their leaves seasonally – but that doesn’t mean they stop growing altogether!
During the spring and summer, olive trees produce new leaves at an incredible rate.
It’s as if they’re trying to outdo each other in a game of “Who can grow the most leaves?”
But then, something strange happens.
As the seasons change, the temperature cools, and the water availability decreases.
This is when the magic of dormancy kicks in.
Olive trees, being the clever plants they are, have developed an adaptation to conserve energy during these harsher months.
They essentially “go dormant,” slowing down their growth and relying on stored energy reserves.
This process isn’t unique to olive trees, by the way.
Many plants exhibit similar behaviors in response to changing environmental conditions.
But what’s truly remarkable about olive trees is just how dramatically they can slow down their growth during this period.
It’s as if they’re saying, “Ah, winter is coming – time to take a little nap!”
So there you have it: the surprising truth about the seasonality of olive trees.
They may not be evergreen in the classical sense, but they’ve developed an incredible strategy for coping with the changing seasons.
And that’s something we can all learn from!

But before we dive into that, let’s explore the benefits and challenges of growing olive trees in different climates and regions.
Pruning Strategies for Olive Tree Seasonality
Pruning is essential for promoting healthy growth and encouraging a bushy shape in your olive tree.
Here are some tips to get you started:
- Timing is everything: Prune your olive tree during its dormant season, which typically occurs from November to February. This allows the tree to focus energy on new growth instead of producing fruit.
- Cut back the branches: Remove any weak or damaged branches to maintain a balanced shape and prevent pests from taking hold.
- Shape the tree: Prune your olive tree to maintain its desired shape, whether that’s a compact shrub or a taller, more slender specimen.
Growing Olive Trees in Different Climates and Regions
Now that you know how to prune your olive tree, let’s talk about where and when to grow them!
Mediterranean Climate: The Golden Rule
If you’re blessed with a Mediterranean climate (think warm summers and mild winters), you’ll want to plant your olive tree in well-draining soil with full sun.
This will ensure it thrives and produces plenty of delicious fruit.
Cold Climates: Be Prepared for Winter’s Wrath
In colder climates, olive trees require more TLC during the winter months.
Make sure to mulch around the base of the tree to protect its roots from freezing temperatures, and bring potted trees indoors if possible.
Hot and Dry Regions: Provide Shade and Water Wisely
If you’re gardening in a hot and dry region (think desert climates), be mindful of your olive tree’s need for shade and consistent watering.
Avoid overhead watering to prevent fungal diseases, and instead opt for drip irrigation or soaker hoses.
And there you have it – the surprising truth about olive tree seasonality!
By understanding your olive tree’s unique needs and adapting your gardening strategies accordingly, you’ll be well on your way to growing a happy, healthy, and productive tree.
