An olive tree grows best in a spacious pot with plenty of root space and good drainage. But how big should an olive tree pot actually be? That is one of the most frequently asked questions we receive at Olivera Garden.
A pot that is too small can cause growth problems, an unstable tree, and roots that dry out more quickly. A pot that is too large is usually less harmful, but there are also points to consider. In this article, I explain which pot size is best suited to your olive tree and what to look for when choosing a suitable olive tree pot.

How big should an olive tree pot be? In short
When choosing an olive tree pot, the following applies:
✅ Choose a pot that is at least 20% larger than the root ball
✅ Ensure there are enough drainage holes
✅ It is better to choose slightly too large than too small
✅ Take future growth into account
✅ Use a sturdy and frost-resistant outdoor pot
✅ Match the pot size to the size of the tree
A good pot size ensures healthy root development and stable growth of the olive tree.
Why the right pot size is so important
Many people mainly look at the appearance of a pot. However, the size of the pot plays at least as important a role.
An olive tree develops an extensive root system underground. When the roots do not have enough space, this can lead to:
- Slower growth
- Faster drying out
- Reduced nutrient uptake
- Yellow leaves
- Reduced frost resistance
Also read our article about yellow leaves on an olive tree to recognize problems early.
How big should an olive tree pot be per tree height?
The guidelines below provide a good indication.
| Olive tree height | Recommended pot diameter |
|---|---|
| 80 – 120 cm | 40 – 50 cm |
| 120 – 180 cm | 50 – 60 cm |
| 180 – 250 cm | 60 – 80 cm |
| 250 cm+ | 80 cm or larger |
These dimensions are guidelines. For older olive trees with a heavy trunk, we often recommend an even larger pot. The exact pot size also depends on the age of the tree, the size of the root ball, and the growth rate.
How big should an olive tree pot be for a young olive tree?
Young olive trees grow relatively quickly and need enough space to form new roots.
Therefore, do not immediately choose the smallest pot available. A slightly larger pot ensures that the tree can grow better and dries out less quickly during warm summer days.
However, always check that excess water can drain away properly.
How big should an olive tree pot be for an old olive tree?
Old olive trees are often heavy and have a wide root base.
For these trees, we usually recommend:
- Large outdoor pots
- Wide pots for extra stability
- Frost-resistant materials
- Sufficient drainage
A large olive tree in a pot that is too small can even become unstable during strong winds.
Is a pot that is too large a problem?
Many people are afraid that a pot that is too large is bad for an olive tree.
In practice, this is usually not the case. A slightly larger pot actually offers advantages:
- More root space
- Longer moisture buffer
- More stability
- Less frequent repotting
However, make sure that the pot does not remain constantly wet. Good drainage remains essential.
Why drainage is at least as important as pot size
A large pot without drainage is often worse than a smaller pot with good drainage.
Always check that the pot has:
- Drainage holes
- A raised bottom
- Water-permeable material
- Sufficient drainage
In addition, use a layer of hydro beads at the bottom of the pot.

Which pot shape is most suitable?
Not only the size of the pot, but also the shape plays a role. Are you unsure not only about the size, but also about the type of pot? Then also read our article Which pot for an olive tree?
Tall pots
Advantages of a tall pot:
- Modern appearance
- Suitable for terraces
- Less floor space required
Wide pots
Advantages of a wide pot:
- More stability
- Suitable for large trees
- More space for root growth
For larger olive trees, we often recommend a wide pot. Are you also unsure about the material? Then also read our comprehensive article Terracotta or plastic pot for an olive tree? in which I explain the differences between terracotta, plastic, and modern composite pots in detail.
When should you repot an olive tree?
An olive tree does not need to be repotted every year.
Signs that repotting is necessary:
✅ Roots are growing out of the soil
✅ Water drains away immediately
✅ The tree is barely growing anymore
✅ The pot dries out quickly
✅ The tree is unstable
Usually, repotting once every three to five years is sufficient. Are you repotting an older or strongly grown olive tree? Then it may be wise to also look at the shape and growth of the tree. For this, also read our guide on pruning an olive tree.
Common mistakes when choosing an olive tree pot
❌ Choosing a pot that is too small
❌ Only looking at appearance
❌ Not taking drainage into account
❌ Using a pot that is too light for large trees
❌ Not taking future growth into account
❌ Forgetting that an olive tree continues to grow for years
Why a spacious pot pays off
Most problems arise because an olive tree remains in the same, too small pot for years. A spacious outdoor pot almost always ensures healthier growth, better moisture regulation, and a more stable tree.
Therefore, when choosing, pay attention to:
- The size of the tree
- The available space
- The desired appearance
- Future growth
- Ease of maintenance
Conclusion: how big should an olive tree pot be?
The ideal olive tree pot is large enough to enable healthy root growth and always has good drainage.
It is better to choose a pot that is slightly too large than a pot that is too small. This gives the tree more space to develop and keeps it healthy for longer.

Frequently asked questions about the size of an olive tree pot
How big should an olive tree pot be for healthy growth?
An olive tree pot must offer enough space for the roots to develop. Preferably choose a pot that is at least 20% larger than the current root ball. A larger pot ensures better root growth, more stability, and a healthier olive tree in the long term.
Can an olive tree be in a pot that is too small?
An olive tree can temporarily be in a smaller pot, but in the long term this can cause problems. The roots have less space, the pot dries out more quickly, and the growth of the tree can decrease. In addition, the chance of nutrient deficiencies and yellow leaves increases.
Is a larger olive tree pot always better?
A slightly larger pot is usually a good choice, because the roots get more space to grow. However, it is important that excess water can drain away properly. A large pot without good drainage can lead to overly wet roots and root rot.
How do I know when my olive tree needs a larger pot?
There are several signs that an olive tree is due for a larger pot. Roots growing out of the drainage holes, a pot that dries out quickly, reduced growth, or an unstable tree are clear indications that repotting is advisable.
Which pot size is suitable for an old olive tree?
Old olive trees often have a larger root mass and a heavy trunk. Therefore, wide and stable outdoor pots are usually the best choice. For large specimens, a pot with a diameter of at least 80 centimeters or larger is often recommended.
Why are drainage holes important for an olive tree pot?
Drainage holes ensure that excess rainwater and irrigation water can drain away. Olive trees do not like prolonged wet roots. Good drainage reduces the chance of root rot, leaf loss, and other growth problems and contributes to the healthy development of the tree.
