You probably know that olive trees like Mediterannean-like climates, right?! Well, that’s where most of the advice on the internet stops. There are not many specific details on what kinds of terrains, locations, etc. olive trees prefer. So, to give you the most detailed information on the best growing conditions for olive trees, I decided to write this ultimate guide, and show you all those tiny details that will allow your olive trees to grow as quickly and healthy as possible.
It’ll probably be a bit longer article, so prepare a few minutes of your time, but I assure you it’ll be worth it. Also, I’ll try to make it as simple as possible for you, so you can follow everything easily.
I’ll organize this article into a few sections, and I’ll thoroughly describe each section, and what’s good for olive trees, and what’s not. So, without further ado, let’s see what I’ve found out. Also, I won’t put an actual location, I’ll show you what should growing location be like instead.
Olive Trees Will Grow Best Under Following Conditions
Here I’ll thoroughly describe what should climate, terrain, and soil be like in order to maximize olive tree growth and yield.
Climate is the biggest factor that affects the growth, development, yield, and lifetime of olive trees, and their fruits properties. When it comes to climate, olive trees have a few specific conditions:
- Relative humidity
The temperature. Ideal temperature conditions for growing olive trees are the areas where day and night temperatures don’t differ a lot. Ideal average yearly temperatures for olive trees are anywhere between 12°C to 20°C (53°F to 86°F).
Temperatures above 32°C (89°F) in May and June, and temperatures above 36°C (43°F) are unfavorable for olive trees. Yet, the upper limit is around 40°C (104°F). There are some sorts of olives that can withstand temperatures up to 52°C (126°F).
When it comes to low temperatures, olive trees can withstand temperatures from -8°C to -12°C (17°F to 10°F), but for 7 to 10 days max. Olive trees will mostly freeze if the temperatures exceed -12°C (10°F).
Precipitation and Relative Humidity. Olive trees don’t like areas with high relative humidity and too many rains. Long periods of high relative humidity are extremely dangerous for olive trees.
Mostly, the climates shown on the map above will have enough rain for olive trees to grow properly. However, they’ll probably need additional watering during the summer season. Here you can check how often to water olive trees.
Insolation. Olive trees are halophytes, which means that they need plenty of sun in order to grow properly and bear plenty of fruits. On average, olive trees should be exposed to the sun for at least 6 hours a day. Ideally, that’ll be 8+ hours.
Winds. The wind is an extremely important factor for olive trees. Olive trees prefer light winds (breeze), which ensures enough airflow for them to grow properly. The right airflow is also important to keep the same temperature and humidity everywhere around olive trees.
During the fertilization process, winds are especially important, since they’ll improve the overall fertilization and later on, the olive yield.
When we talk about terrain conditions, some conditions should be met in order for olive trees to grow the best. Olive trees prefer areas with a slight slope, which increases the exposure to the sun and airflow. Slopes should be anywhere between 5% to 15%.
South and southwest positions of terrain are much better than the ones with northern exposition. South and southwest positions ensure that the trees will acquire enough sunlight during the day, which is extremely important in the winter period.
When it comes to the elevation, growing olive trees is possible up to 400m (1300ft). Everything above isn’t so suitable for growing olive trees.
When it comes to the soil quality, olive trees are very humble. Olive trees don’t need extremely fertile soils in order to grow properly. Yet, there are some conditions that should be met.
Olive trees don’t prefer soils that keep too much water (clay soils), but they also don’t like types of soils that drain all the water (sandy soils).
A mix of sandy-loamy soil is a good option for olives, especially limestone soils that are neutral and slightly acid such as terra rosa. Furthermore, the ideal soil pH value is about 6.5.
Also, soils that are acid and not rich in calcium aren’t suitable for growing olive trees, yet, you could do a calcification (a process of soil enrichment with calcium), to make the soil suitable.
