Olive trees are native to the Mediterranean, central Asia, tropical Asia, and Africa and have a rich history and cultural significance, symbolized by the olive branch as a peace offering.
Olive Trees grow best in environments with mild winters and warm, long, dry summers that allow for fruit production.
Ericaceous compost can be used for growing olive trees, as they can thrive in soils with a pH of 5.5 to 8.5.
Although ericaceous compost has a slightly lower pH (4.0 to 5.0) compared to what olive trees require, they can still grow in it.
It is important to ensure proper soil drainage, so the trees do not become waterlogged.
Optimal Compost for Growing Olive Trees
Olive trees growing outdoors perform well in soil with good drainage and do not require compost.
Instead, slow-release fertilizer is recommended to provide the necessary nutrients.
For olive trees grown in pots, a mixture of compost and John Innes No 3 can create a favourable environment for growth.
A well-draining potting mix is best for olive trees grown in pots and indoors, with a balanced sand, silt, and clay ratio and a pH between 6 and 8.
Growing olive trees in good drainage soil are critical for their survival.
They do not thrive in waterlogged soil, which can cause root rot and other problems.
It is recommended that you avoid using soil mixes known for retaining water to ensure that your olive trees have the best chance of success.

Suitable pH Range for Olive Tree Growth
Olive trees are relatively adaptable regarding soil pH and can tolerate a pH range from 5.5 to 8.5.
However, the ideal pH for olive trees is between 6.5 and 8.0, with a neutral preference for alkaline soils.
The most critical factor for olive tree growth is soil drainage.
Olive trees do not thrive in waterlogged soil, and it is important to ensure that the soil has good drainage to prevent water build-up around the roots.
It is important to test the soil first to determine its pH level to grow olive trees.
If the soil has a high pH or is alkaline, ericaceous compost can bring the pH to a more suitable level for olive trees.
This type of compost is made from acidic materials such as pine needles or oak leaves and has a pH range of 4 to 5.
Using ericaceous compost helps create ideal growing conditions for olive trees, as it lowers the pH of the soil to a more suitable range.
I think these olive trees are so great. Lots of them on @ASU campus all gnarled and grand, likely 60-80 years old. They originate from the Mediterranean but do well

Role of Ericaceous Compost in Reducing Soil pH
If the soil is alkaline, adding ericaceous compost can help lower the pH to a range suitable for olive trees.
Ericaceous compost is a type of soil amendment created from materials with an acidic nature, like pine needles or oak leaves.
It has a pH level of 4 to 5, which benefits plants that require low-pH soil for optimal growth.
Making ericaceous compost at home is a straightforward process that requires gathering the necessary materials and allowing them to decompose over time.
The result is a nutrient-rich soil amendment that helps lower the pH of the soil to a more acidic range, making it suitable for plants.

What Type of Soil Is Optimal for Olive Plant Growth?
For olive trees planted outdoors in the ground, a well-draining soil that contains a mix of chalk and clay and is rich in organic matter is ideal.
A pH level between 5 and 8.5 is preferred for the soil, with a moderate acidity or alkalinity acceptable.
Good drainage is essential to prevent waterlogging, which can negatively impact the growth and health of the trees.
Adding organic matter to the soil can also help support the growth of olive trees by improving the soil’s nutrient content and structure.
What Are the Requirements for An Olive Tree to Thrive?
Olive trees thrive in areas that have hot and dry summers followed by mild but cool winters.
Olive trees need a period of dormancy that lasts for two months and where the temperatures are ideally between 40°F to 50°F to produce fruit.
During this time, the trees are inactive, and the cool weather helps them to prepare for the next growing season.
However, extremely cold temperatures in winter, below 20°F, can cause damage or even death to unprotected olive trees.
Do Olive Trees Require Abundant Water For Growth?
Olive trees are known for their ability to survive with limited water, but they still need a sufficient amount of water to grow and thrive.
During the establishment stage, keeping the soil moist but not soaking wet is important.
It is recommended to water an olive tree once a week during the first year or whenever the top 2 inches of soil becomes dry.
This will help the tree grow strong roots and adapt to its new environment.
Do Olive Trees Require Direct Sunlight?
Olive trees require full sun exposure and at least six to eight hours of direct sunlight to thrive.
Olive trees require a lot of sunlight to thrive and should be placed in a location with plenty of bright, direct sunlight.
Ideally, this would be an area facing east or south, such as a well-lit room with a large window facing those directions, such as a living room.
This location provides the tree with six to eight hours of bright sunlight, which is essential for the tree’s survival.
Can Olive Trees Tolerate Rain?
Olive trees require well-drained soil to avoid waterlogging, especially during rainy weather.
Ground-planted trees are especially vulnerable to waterlogging, so it is important to ensure they are planted in soil that allows excess water to drain.
For potted olive trees, adding a layer of fleece around the pot is advisable to provide additional warmth in case you cannot move it indoors during rainy weather.
Conclusion
Olive trees can adapt to various conditions, making them suitable for growth in ericaceous compost.
They can thrive in soil with a pH range between 5.5 and 8.5 and are typically able to grow in soil with low nutrient levels and rocky sand if proper drainage is ensured.
Olive trees can tolerate both acidic and alkaline soil.
However, they prefer soil that is neutral to slightly acidic.
Ericaceous compost can adjust the soil pH if it falls outside this range.
It helps lower the soil’s pH and makes it suitable for plants that require acidic conditions, such as olive trees.
