An olive tree (Olea europaea) is one of the most popular Mediterranean trees in the Netherlands and Belgium. With its characteristic trunk, silvery-green leaves, and Mediterranean appearance, it instantly brings atmosphere to any garden, patio, or balcony.
Olive tree care in brief
Do you want to care for your olive tree and keep it healthy? Then pay attention to these basic rules:
✅ Place the tree in a sunny spot
✅ Better to water less than too much
✅ Use Mediterranean plant food during the growing season
✅ Ensure good drainage in pots and the ground
✅ Protect the tree during severe frost
✅ Regularly check for leaf discoloration and growth problems
Why the right care is important
Olive trees are accustomed to dry, sunny conditions around the Mediterranean. However, in the Netherlands, we have to deal with a lot of rain, wet winters, and fewer hours of sunshine. As a result, most problems are not caused by drought, but rather by too much moisture.
You can recognize a healthy olive tree by:
- Firm, silvery-green leaves
- Compact growth
- Strong new shoots
- Good root development
- Little leaf loss
With the right care, an olive tree can live for decades.
Olive tree care: the ideal location
An olive tree loves warmth and light. The more hours of sunshine the tree receives, the better it grows.
The ideal location:
- At least 6 hours of direct sunlight per day
- Sheltered from harsh northern winds
- Good air circulation
- No prolonged wet soil
A spot in the south or southwest is usually ideal. Also check out our collection of Mediterranean plants for various sizes and types.
Olive tree in a pot or in the ground?
Both options are possible.
Advantages of an olive tree in a pot
- Flexible to move
- Easier to protect against frost
- Suitable for the patio and balcony
Advantages of planting in the ground
- Stronger root growth
- Dries out less quickly
- Better development in the long term
When planting an olive tree in a pot, always use a spacious pot with good drainage. This allows excess water to drain away easily and keeps the roots healthy.
Caring for an olive tree with the right amount of water
Many people think that an olive tree needs a lot of water regularly. In reality, an olive tree is quite drought-tolerant.
Too much water causes:
- Yellow leaves
- Root rot
- Leaf drop
- Poor growth
Therefore, always check the soil before watering.
Watering an olive tree in spring and summer
During warm periods, the tree grows actively.
Guideline:
| Situation | Watering |
|---|---|
| Olive tree in a pot | 1 to 3 times per week |
| Olive tree in the ground | Only during prolonged drought |
| Heatwave | Check extra |
The soil may dry out slightly between two waterings.
Watering in autumn and winter
In winter, an olive tree uses much less moisture.
Only water when:
- The soil is completely dry
- The tree is under a cover
- There has been no rainfall for a longer period
In wet winters, extra water is often not necessary at all. Want to know more about exactly how much water an olive tree needs? Then read our complete article on how much water does an olive tree need?
What food does an olive tree need?
An olive tree uses nutrients for:
- New shoots
- Healthy leaves
- Strong roots
- Resistance to diseases and frost
Especially olive trees in pots need regular food.
When to fertilize?
The best period runs from: March to September
Feed the tree approximately:
- 1 time per month with liquid food
- Or according to the dosage of a slow-release fertilizer
From October, stop fertilizing so that the tree can prepare itself for winter.
What food is suitable?
Preferably use special Mediterranean plant food.
Important are:
- Nitrogen for growth
- Potassium for firmness
- Magnesium for leaf color
- Trace elements for healthy development
A balanced food prevents common problems such as yellow leaves.
Yellow leaves on an olive tree
Yellow leaves occur regularly on olive trees and can have different causes. To solve the problem properly, it is important to first determine the cause.
Too much water
In the Dutch climate, too much moisture is one of the most common causes of yellow leaves. When the roots remain wet for a long time, they can absorb less oxygen.
Therefore, check:
- Drainage of the pot
- Drainage of the soil
- Whether excess water can drain away properly
Too little water
During warm summers or prolonged drought, an olive tree can also develop yellow leaves due to a lack of moisture. Especially olive trees in pots dry out faster than trees in the ground.
Check whether:
- The root ball is completely dried out
- The leaves hang limp
- The pot soil is pulling away from the pot edge
Nutrient deficiency
A deficiency of nutrients such as magnesium, nitrogen, or iron can lead to yellowing of the leaves. Especially olive trees in pots are dependent on regular fertilization because nutrients disappear from the pot soil over time.
Solution:
- Give Mediterranean food
- Fertilize regularly during the growing season
Natural leaf loss
An olive tree constantly renews its leaves. When a few older leaves turn yellow and fall off, that is normal. Only when many leaves discolor or fall off at the same time is further investigation needed. In our extensive guide on why an olive tree loses leaves you will read which causes occur most often and how you solve this problem.
The right potting soil for an olive tree
Good drainage is essential. Olive trees absolutely do not like wet feet.
A suitable mix consists of:
- Mediterranean potting soil
- Lava
- Pumice
- Coarse sand fraction
This keeps the root zone airy and allows excess water to drain away quickly.
For a pot, we always advise:
- Drainage holes at the bottom
- Bottom layer of hydro beads or lava
- Suitable Mediterranean potting soil
- Spacious pot size
For large olive trees, a large outdoor pot is important, so that the roots have enough space to develop and excess water can be properly drained away.

Pruning an olive tree
When to prune?
The best period is: March to May
Then the tree recovers quickly from the pruning.
How do you prune an olive tree?
Remove:
- Dead branches
- Damaged branches
- Crossing branches
- Water sprouts
Try to keep the crown airy so that sunlight can reach everywhere.
Tip from Olivera Garden
Better to prune lightly every year than extremely heavily every few years. This way, the tree retains its natural Mediterranean appearance. Do you have specific questions about the pruning of an olive tree? Then feel free to contact Olivera Garden.
Does your olive tree get brown, curled, or black leaves?
During the care of an olive tree, you may notice that the leaves discolor or start to curl. Brown, black, or curled leaves are often a reaction to drought, too much water, frost damage, or root problems. Fortunately, this does not automatically mean that the olive tree is dead. By recognizing the cause in time, you can prevent the damage from getting worse in many cases.
Do you want to know exactly what causes these leaf problems and how to get your olive tree healthy again? Then also read our extensive article Brown, curled, or black leaves on an olive tree. There we explain step by step how you recognize the different symptoms and which solution best suits your situation.
Caring for an olive tree during the winter
An adult olive tree can tolerate light frost.
Problems usually occur with:
- Prolonged frost
- Strong easterly wind
- Wet roots in the winter
For olive trees in pots

Frequently asked questions about caring for an olive tree
How often should I water an olive tree?
How often you need to water depends on the season, the temperature, and whether the olive tree is in a pot or in the ground. In summer, an olive tree in a pot often needs water one to three times per week. Always check the soil first. The top layer may dry out slightly before you water again. Too much water is more harmful than too little.
What is the best location for an olive tree?
An olive tree prefers to be in a sunny, warm spot with at least six hours of direct sunlight per day. A location in the south or southwest is ideal. In addition, ensure shelter from harsh wind and a well-draining soil so that excess water can drain away quickly.
What food does an olive tree need?
An olive tree grows best with special Mediterranean plant food. This contains the right ratio of nutrients for healthy roots, strong growth, and beautiful green leaves. Fertilize the tree from March to September according to the recommended dosage. In winter, an olive tree does not need extra food.
Why does my olive tree get yellow leaves?
Yellow leaves are usually caused by too much water, a lack of nutrients, or natural leaf renewal. First check whether the roots are not too wet and ensure good drainage. When especially older leaves turn yellow and fall off, this is often a normal process.
Is an olive tree winter hardy in the Netherlands?
Yes, an adult olive tree can tolerate light frost. During prolonged frost and temperatures below approximately -7°C, we advise to apply extra winter protection. Especially olive trees in pots are more sensitive to frost because the roots are less protected than in the ground.
Can I leave an olive tree outside all year round?
In most cases, yes. Olive trees are well suited for the Dutch climate, provided they are in a sunny location and do not remain with wet roots in the winter for a long time. During severe frost periods, it is wise to protect the pot, trunk, and root ball extra with winter fleece or insulation material.
How do I care for an olive tree in a pot?
An olive tree in a pot requires slightly more attention than a tree in the ground. Water regularly during warm periods, use Mediterranean food in the growing season, and ensure a spacious pot with good drainage. In addition, check annually whether the tree has enough root space and repot to a larger pot if necessary.
