What is the Best Soil for Olive Trees in Pots?
A well-drained potting mix is the best soil for olive trees in pots. Such potting soil is a mix of equal parts of peat, sand, perlite or bark, and organic matter. These are the structures you need to allow water and air circulation, as well as the formation of adequate root systems for nutrient uptake.
For example, large size particles have a larger space between them and provide plenty of air to the roots of an olive tree. On another hand, plenty of small particles hold on required moisture. To be honest, the potting mix is better draining than the average garden soil.
The ideal potting mixture will also contain micronutrients like potassium, nitrogen, and phosphates, which are complemented by micronutrients.
When choosing the best commercial potting mixture it’s always worth checking the ingredients written on the package. Truth is, that potting mix with too much soil in it may be too moisture retentive to make an ideal potting medium.

When the olive tree outgrows its pot every three to four years, it is best to use a fresh batch of the potting mixture to replace the old medium.
You can either move the olive tree to a larger pot or prune the roots. Then re-pot it in the same pot with a new potting medium. In fact, ceramic or wooden pots are better for olive trees comparing plastic, metal, or glass pots which help to retain moisture. Indeed, ceramic and wood allow more evaporation.
Evaluating Soil for Olive Tree
So far, we have answered the fundamental question of what is the best soil for olive trees in pots. However, the soil’s ability to support healthy olive tree life is determined by its physical, chemical, and biological composition.
You can examine some soil properties like texture or color by your eye or moisture by touching with your hand. However, you cannot do the same for chemical properties in the soil. Therefore it is crucial to test your potting soil.
So why testing soil is so important? Testing is done to make recommendations as to whether the potting mixture needs pH adjustments or additional nutrients.
For example, testing informs you of the soil’s health and eliminates events of over- or under-fertilization, which could lead to olive tree death. as well, olive trees are completely intolerant of poor drainage, so it is important to test the moisture in a pot.
You can test your olive tree soil inexpensively at home. Studies showed that home testing kits post results comparable to laboratory tests.
Furthermore, technology has evolved a lot, and currently, home test kits are made safe and easy for you to use with most of them being plug and read gadgets. Therefore you must test your soil for the best experience in growing your olive tree in a pot.
After testing is done, if it informs your olive tree requires a refill of macronutrients like phosphorous, potassium, sulfur, and nitrogen, consider adding olive tree fertilizers. Again, there are many good fertilizers on a market, so my guidelines on what is the best fertilizer for olive trees in pots may help.
What is Soil pH for Olive Trees in Pots?
The ideal soil pH for olive trees is between 6 and 7. In case you have a potting mix that is too acidic or basic, you can add lime to raise soil pH. Otherwise, added sulfur will lower it.
If you just want to test potting soil pH, simple pH testing strips are available online and at many gardening supply stores.
Once the soil pH level is adjusted for the olive tree you are growing, do not put it out of your mind. Maintaining the correct pH level for your potting soil is an ongoing task, especially if the tree grows in a pot and indoors.
Even fertilizers can shift your olive tree soil pH over time. Hence, there’s a need for regular additions of limestone or sulfur-based on testing results.
Ensuring Soil Drainage When Planting
While you might be concerned about what is the best soil for olive trees in pots, it also vital for you to ensure the right soil drainage when planting a tree. Here are listed a few tips on how to ensure soil drainage:
- Choosing a pot with plenty of drainage holes in the bottom prevents excess water from smothering olive tree roots.
- Furthermore, to ensure proper drainage, you can put 1 – 1.5 inches (2.5 – 4 cm) of gravel or lava rock or small rocks in the pot beneath the potting mix.
- It is also a good idea to put a layer of gravel or lava rock in any tray the olive tree pot sits on to prevent the roots from sitting in water.
- A layer of the screen at the very bottom of the pot can help contain the potting mixture and gravel if the pot has large drainage holes.
Well, olive trees in pots will tolerate either acidic or alkaline conditions but good drainage is extremely important. In fact, good drainage is the most important thing to consider when growing olive trees in pots or containers!
