1. Choose Pot Size for Your Olive Tree Carefully
The first major problem with olive trees in pots has to do with the pot size: it is harmful to the expanding root system if the pot is too small. An olive tree will quickly grow roots that hit the sides of the container and turn. Within no time the pot is full of circling roots, and the olive tree becomes pot-bound.
When the pot is too small for your olive tree, the solution is re-potting described below.
Tips on How to Choose the Right Pot for Your Olive Tree
* It should suit the style of your home, garden, patio, and landscape
* Large enough to house the root ball of your olive tree
* Ensure that the pot has a sufficient amount of drainage holes
* Do not put a small olive tree in a very large container; instead, size up the pot in stages
* Pick a much larger pot or container if you prefer to grow suitable and best companion plants for olive trees
* If you need extra stability to prevent olive trees from blowing down in windy weather, choose heavy frost-proof terracotta pots with drainage holes. However, the sponginess of these pots means the compost dries out quickly and the weight makes them difficult to move around
* Clay pots are heavy and keep the tree stable in windy conditions, especially with larger trees
* A lighter-weight plastic garden pot is a good choice if your olive tree is small and up to a couple of years old and they are good at retaining moisture
* Metal, wood, and stone pots are also suitable, there is no hard rule while choosing a pot

2. Re-Pot Your Olive Tree Each Several Years
Several years after planting olive trees in pots, the trees circling roots will begin to strangle the trunk, ultimately causing the death of the olive tree. As to avoid it, the olive trees need repotting every three to five years.
One of the symptoms of a too crowded pot includes leaves that turn yellow and drop off. Or if you notice roots escaping from all drainage holes, re-pot the tree instantly. Otherwise, if only one root has escaped from a drainage hole accidentally, trim off it without the urgent need to repot.
In terms of olive tree transplanting, we have an in-depth guide on how and when is the best time to re-pot olive trees. After following these repotting steps, you can easily get rid of one of the most common problems with olive trees in pots.
Remember re-potting an olive tree once per few years not only boosts the tree growth but as well restores the nutrition of the potting soil.
Don’t Make This Mistake when Re-potting Your Olive Tree
The most common problem when the olive tree is re-potted involves the depth of the trunk and root system in the pot. Too often the olive trees are planted a little bit too deep in the pot, causing root defects. When planted an olive tree into the pot, make sure to set the tree in the pot so that the soil line on the root ball is about 5 cm (2 inches) in depth.
As well you can run into problems if the pot is too large for the current olive tree size. When soil present is abundant and not enough roots to take up the water, it can retain moisture for too long and cause root rots that can ultimately kill the plant.
3. Protect Your Olive Trees in Pots from Cold & Freezing Weather
While an olive tree planted in the ground can take mild frost and cold, an olive tree in a pot or in a container cannot. Olive trees in pots suffer serious damage at temperatures below 25 degrees F (-4 °C).
In exposed gardens, olive trees in pots winter care are necessary in order to protect roots growing near the edges which are vulnerable to freezing temperatures.
Best Ways to Protect Your Potted Olive Tree from Freezing Weather
Wrap it overnight
When freezing weather threatens, provide two layers of protection by covering the tree with a blanket and then a sheet of plastic or a bubble wrap. Remove the covering the following day.
Move Your Tree Inside
For protection from prolonged periods of freezing weather, you may start thinking about moving olive trees indoors for winter. Bringing a large potted olive tree is a job for 2 people at least – don’t try to do it alone because you may injure your muscles if you are not careful.
If you moving a tree alone, attach wheels to the bottom of the pot or use a hand truck to transfer the tree.
Check Overall Health
Prior to bringing any trees indoors, consider their health. Be sure to check your olive tree for any pest. If your olive tree does have pests, we recommend treating it two weeks prior to moving it indoors. Once the pests are under control, you can prep your plants for going inside.
Before moving your olive trees in pots indoors, be certain you have the right location for them. They will thrive best if placed near a southern-facing window with bright sunlight coming inside.
Use a spray bottle and mist the leaves daily in order to provide more humidity for your olive trees, especially when you have the heat running and your home feels dry. If there is not enough moisture in the area, the foliage on your trees will become dry, crispy, and may even turn brown. Water thoroughly when the soil doesn’t feel moist to the touch.
4. Olive Tree in Pot Pest Management
No matter that the olive trees are one of the most pest-resistance trees, there are still sometimes problems with pets of pot-grown olive trees. The most common pests are fruit flies, scale insects, and aphids.
Let’s go through some practical tips on how to get rid of scale insects – the unwelcome but popular “guests”. You can apply this technique to aphids and other pests as well.
* If the potted olive tree is indoors, move it outdoors to expose the pests to their natural enemies.
* Handpick scale insects to control light infestations.
* Olive tree treatment with insecticidal soap or neem oil is often effective and kills these insects. Spray the undersides of the leaves of scale with a ready-to-use Safer brand insecticidal soap or organic neem seed oil available on Amazon. Repeat weekly, if necessary.
* If soap spray doesn’t resolve the pest problem, try light agricultural (horticultural) oil (Amazon link attached). Carefully read instructions and make sure you spray the entire tree, including the undersides of the leaves. Wear long sleeves, long pants, and gloves when spraying horticultural oil to prevent skin irritation.
* Also, if you can not get a spray from the shop, then try to use substitutes found at home, for instance: lemony soapy water or cotton soaked in alcohol. Just wash away pests from all parts of the olive tree.
5. Common Problems with Olive Trees in Pots is Watering Issue
Another problem with olive trees in pots is watering issues because the tree will dry out far more quickly than those growing in the ground and will need regular watering. If tree roots are not kept moist, potted olive trees quickly struggle to survive.
The real problem with olive trees in pots is sitting in the wet soil. You can leave your tree outside but out of the constant rain. If you live in a rainy area, you should bring the potted tree inside and keep it on the south side of your house in the sunniest place.
For instance, the self-watering pot puts soil inside hollow legs that reach down into the water. As a result, it draws moisture naturally without wicks. Simultaneously it lifts your plant above standing water. As well, it keeps the plant’s delicate root system from being constantly flooded. Basically, such a great invention eliminates common problems associated with olive tree overwatering symptoms and mold and fungus.
To simplify regular olive tree care for you, we have prepared a complete guide on water requirements for olive trees in pots in order to learn how to avoid overwatering or underwatering issues.
How often to water Olive Trees in Pots?
Once re-potted in well-draining soil make sure to water your olive tree every day to establish roots. Afterward, water your olive tree in the pot 1-2 times per week depending on overall environmental conditions. In the winter, you can stretch this once every 2 weeks.
Simple keep the soil moist, but not wet, at all times, even during winter when soil can dry out quickly in the wind if kept outdoors.
Drainage is Essential
Even if you have the correct size of the pot for your olive tree, you can run into root rot and other problems if there are not enough drainage holes.
Always check the bottoms of your pot, ensure the holes are not obstructed. Use a drill to create more holes as needed for controlling water excess. Fill the bottom of the pot with a layer of gravel, Styrofoam, lava rock, crushed cans or stones which helps to drain the water faster.
Just do it once prior to potting your tree, and you will have fewer problems with olive trees in pots.
6. Regular Fertilization for Your Olive Tree
Choose the balanced fertilizer for olive trees and use it at least twice a year during the growing season in spring and for fruit maturing in mid-summer.
Avoid compost and mulches, these are often too heavy and moisture-retaining for olive trees. Use a small amount of any normal store-bought nitrogen-based fertilizer, following the package’s instructions. You fertilize the tree to give back nutrients that have been depleted over time.
As well, you can give a new soil while re-potted to basically restore olive tree growth. Give trees in pots a boost, by refreshing the top layer of soil annually in spring. Carefully scrape away about 2.5 cm (1 inch) of soil from the surface and replace it with fresh soil – mix in some controlled-release fertilizer granules.
7. Save Olive Trees Losing Leaves
Another most common problems with olive trees in pots are olive tree dropping leaves. Mainly it happens due to water issues:
Olive trees love water, however, they hate to be too wet and in constant moisture. Particularly, olive trees in pots since they have limited space in a pot.
So if your olive tree is overwatered, it starts losing leaves. Normally, leaves get yellow and start dropping. Read more on olive tree overwatering symptoms.
Therefore, sometimes olive trees losing leaves in summer. And the reason is that the tree gets too dry too often. So the olive tree leaves dry out and starts dropping.
How to water your olive tree correctly, review our detailed article on water requirements for olive trees in pots.
8. Other Problems with Olive Leaves
In general, olive leaves can tell us about many problems with olive trees in pots. For instance, you notice that your olive tree leaves turn yellow or brown. If it happens only to a few leaves, I wouldn’t worry about that – it may be a natural seasonal change.
However, if you observe them closely and you notice that olive leaves turn yellow with brown blotches moving in from the edges to tips. This may be leaf necrosis – a sign of drought stress – and if no action is taken, the leaves will fall off and the tree could die too.
On a whole, olive tree leaves can tell us so much about tree health and growing conditions. In addition, to signaling drought stress, they can show us if the tree is experiencing nutritional deficiencies, water issues, or even if it is fighting with pest and disease problems. So our job as gardeners is to recognize the symptoms and to satisfy olive trees’ needs before it’s too late.
For this reason, I have gathered lots of useful information for olive tree growers and created separate articles depending on olive tree leave issues:
- Olive Tree Leaves Turning Brown
- Olive Tree Leaves Turning Yellow
- Olive Tree Leaves Curling
- Olive Tree Leaves Dropping Off
- White Stuff on Olive Leaves
9. Sucker Branches Weaken Your Olive Tree
Regardless of how well you take care of your potted olive tree, growing in a container or pot will be more stressful on the plant itself. You will need to keep an eye out for unique problems that potted olive trees can have.
For example, olive trees growing in pots or containers are more susceptible to sucker branches. These are branches that grow from the scion or rootstock of the tree and consume your tree’s nutrition. As a result, weakens the olive tree.
Many times, in order to grow a hardier olive tree, nurseries will grow the desired tree on a hardy root. However, under stress, the rootstock will try to take over the olive tree. If you see a sucker branch grow from the bottom of the olive tree, prune it immediately and your olive tree will regain its position.
10. Bark Split or Holes in Olive Trunk
Olive tree bark split is very common for olive trees, the older olive tree gets the more twisted and split trunk is. Also, deep holes may appear on a trunk.
If you see them, don’t worry, it doesn’t affect olive tree longevity. It is caused by changes in growth conditions, e.g. dry weather following by wet weather conditions, sunscald, age, and other reasons.
11. Transition Shock
When you do move your potted olive trees outside do be aware that a sudden change in light levels can cause ‘sunburn’.
To avoid this, place your olive tree in a partially shaded spot for a few days before moving into full sun or move it outside for a few hours a day until it has adjusted to its new position.
Because too dramatic a change in light levels can lead to blanching of the olive leaves and some leaf loss but over time your olive tree will recover and put on new growth.
12. Worries About Moss on Your Olive Tree
Moss is often growing on the stems, branches, and trunks of olive trees and is often a worry to gardeners. Indeed, it indicates a lack of vigor in the affected olive tree. However, moss on olive trees is harmful and is not considered one of the “deadly” problems with olive trees in pots.
|Areas affected||Trunks and branches of olive trees|
|Main causes||Humidity, damp, no air circulation, still conditions and poor olive tree vigor|
|Appearance||Form large green or yellowish-green tufts, densely matted tufts, or compacted green cushions|
|Timing||Moss appears year-round, but are more noticeable in winter|
Moss Growth on Olive Tree Reasons
Basically, moss is found in damp humid places, because it needs moisture for growth but as well for reproduction. These are the reasons and conditions preferable for moss to grow on branches and twigs of olive tress:
- Your olive tree has been neglected. For instance, if the branches of your olive tree have become overcrowded and not os much sunlight reaches it.
- Humidity issue. Moss can also appear on a vigorous new olive tree in humid areas.
- Bad conditions. The side of olive tree trunks facing the prevailing wind and rain may be colonized by moisture-loving mosses.
- Poor vigor. Olive trees in pots that are lacking in vigor, especially those which are already beginning to die.
How to Control Moss on Olive Trees in Pots?
Even so, we have just learned that moss is not causing “deadly” harm to your tree, it still shows the tree is lacking vigor and needs some attention. For this reason, I have put together the solutions that help to control moss on your olive trees in pots and outside:
- Improve air circulation. it will help to avoid dump and humidity.
- Prune out overcrowded branches. In this case, you let the sunlight get into the trunk of the tree and reduce moisture. As well, cut back overhanging vegetation.
- Remove moss. Simply remove moss from trunk and branches as stop its reproduction.
- Stimulate new growth. Fertilize, water, and mulch your olive tree correctly.
13. Detected Fungus on Olive Tree
Tree fungus is a common problem on olive trees. Not all fungus growing on your olive tree is harmful; some do not affect your olive tree at all, while others can be even beneficial. However, in most cases being infected with a tree fungus will result in loss of vigor and discoloration or wilting of leaves.
|Common name||Tree Fungus or Fungal Disease|
|Areas affected||Trunks and branches of olive trees|
|Main causes||Humidity, damp soil, overwatering, no air circulation, still conditions, too many fallen leaves|
|Appearance||Mushroom, shelf or jelly fungus; other shapes, colors, and texture fungus growing around your olive tree; sometimes cant be seen above the ground|
|Timing||Moss appears year-round, but are more noticeable in winter|
If your potted olive tree has a fungal disease, you mays see mushroom fungus, shelf fungus or other shapes, colors and textures of fungus growing on your olive tree. Unfortunately, sometimes the tree fungus may not appear above the ground or may have a different appearance than you expect.
For the best advice, is better to speak with the arborist and he/she will be able to identify if the fungus is harmful and what treatment is required.
