olive trees

If you are someone with an interest in how nature works, then it would make sense to pay attention to trees. As one of our most beautiful and important natural companions, trees are vital to our society. They provide us with a means of improving oxygen, and trees have long been used as gorgeous natural décor. Whether planted intentionally or built around due to their prominent location, trees are a very common part of our world. Trees come in all shapes, sizes, and purposes – many trees allow for natural items to grow in their presence.

For that reason, many people today realise that things like olive trees are very important. They give us a way to collect olives, which can then be used in cooking, sold on as a food product, or used for various other essential uses. The taste of olive oil has made it one of the most popular options to use when it comes to the creation of cooking oils, too. However, if you ever wish to properly grow an olive tree, then you must make sure that you do so in the right conditions that are suitable.

One common question is whether or not olive trees can grow in a colder climate. Most assume that olives are warm-weather suitable produce because they are so commonly grown in Mediterranean countries such as Italy. However, olive trees actually produce their best work when you are in the cold!

Why do olives need cold weather?

Since olives are so commonly used as produce in Italy, most assume their olives appear during their rich and long-lasting summers. However, this is simply not the case. Olive trees are hardy, durable trees that need the winter weather to help naturally grow their olives. While we mostly associate olive trees with warmer nations such as Greece and the Middle East, olive trees actually need the cold to make sure they can produce as intended.

Cold is required for the proper blooming and the olive to begin to appear. Indeed, many olive trees within more temperate climates actually need cold weather to thrive. If they are planted in a location with a weather pattern that is too mild, the tree itself will never enter a period of dormancy. This has an impact on the flower buds, meaning that they never truly mature.

This is a major issue, as olive trees which are planted in a rich and tropical climate are less likely to ever bear fruit. However, the actual amount of the cold needed – and the duration of cold required – will change depending on where you are in the world.

For example, Italian olive trees such as the Frantoio olive tree will need as much as 600 hours at a temperature of around 7 degrees Celsius. The Italian regions that tend to grow all of the olives tend to be the colder parts of Italy where the winters are longer and colder.

Olive trees need the cold to create flowers

The challenge is that many olive trees need hundreds of consecutive hours of specific temperatures to start springing some olives in the first place. If a tree is not given enough of the chilling effect above, then you could notice that your olive tree simply produces a collection of branches and leaves but no actual flowers. When a tree begins to find the right kind of temperature balance, though, the flowers can begin to appear.

Once the cold period is set in stone, though, the tree actually needs a warmer temperature to allow for the growth to begin and for the tree to begin heating up. This means that you want to make sure that your olive trees are put through the needed cold period and then you make the adjustment to allow for extra heat.

However, excess heat before the process is ready could mean that the flowers bloom and wilt before they have pollinated. Naturally, that is going to have a negative impact on the quality and quantity of the olives being grown.

If you are going to go through the process of growing an olive tree, then you must research a few things. First, focus on the coldness of where you live versus the level of coldness your tree will need. Also, factor in how you can improve the heating conditions without getting too warm too quickly. Research the olive tree type you are intending to grow, and make sure you create the conditions needed to allow for growth.

As far as growing olives in a cold country go, though, you need the coldness to get the show on the road. Keep that in mind!
