The olive tree is a versatile and hardy plant that can thrive both in the field and in pots. However, for a potted olive plant to grow strong and healthy, it is important to provide it with adequate nutrients through fertilization. Fertilization is essential for the growth of any plant, especially in pots where the amount of available nutrients is limited.
In this article, we’ll explore the most important aspects of fertilizer for olive trees in pots, including which nutrients are essential, when and how to apply them, and how to choose the right fertilizer for your olive tree. By following these tips, you will be able to provide your potted olive tree with the necessary nutrients to thrive and produce healthy olives.

Cultivating a large plant like the olive tree in a pot gives us some advantages, better use of space, greater control in the location of the plant, problems associated with large plants such as falling branches, clogging of gutters of our home. etc. But not all are advantages, growing an olive tree in a pot is not easy. To begin this post we will analyze the most common problems associated with growing olive trees in pots.

1. Problems with olive trees in pots
Growing an olive tree in a pot presents some problems, including:
- Lack of space: Olive trees are large trees and, as such, require a large amount of space to grow. In a pot, the amount of soil available is limited, which can limit the growth of the tree.
- Difficulties in maintaining a suitable environment: The quality of the soil and the level of humidity in a pot must be carefully controlled to guarantee a healthy environment for the olive tree. If they are not properly maintained, there can be a buildup of salts in the soil and a decrease in the amount of available water.
- Health problems: Growing in pots can expose the olive tree to a number of health problems, including soil diseases, pests and fungi. These problems can be especially serious if good pest control practice and proper fertilization are not followed.
- Risk of incorrect watering: Watering incorrectly, either with an excess or a lack of water, can be detrimental to the potted olive tree. Excessive watering can cause a buildup of salts in the soil and a decrease in the amount of oxygen available to the roots, while insufficient watering can cause a decrease in olive production and a decrease in the general health of the plant. Therefore, it is important to ensure that you water properly and regularly to ensure a healthy environment for the olive tree.
However, some of these problems can be solved with correct fertilization. By providing the necessary nutrients to the plant, its immune system can be strengthened and health problems prevented. Also, by choosing the right fertilizer, you can help maintain a healthy balance in the soil and prevent salt buildup.
2. NPK values in commercial fertilizers
NPK values in a fertilizer refer to the proportion of nutrients Nitrogen (N), Phosphorus (P) and Potassium (K) found in the product. These nutrients are essential for the growth and health of plants.
2.1 How to interpret NPK values
NPK values are displayed in a format like 10-5-5 or 20-10-10, for example. The first number represents the nitrogen content, the second number represents the phosphorous content, and the third number represents the potassium content.
2.2 What is it for and how will it help us to use a fertilizer correctly?
Each nutrient plays a specific role in the growth and health of plants. Nitrogen is important for leaf and branch growth, phosphorus is important for root development and flower and fruit production, and potassium is important for plant resistance to disease and adverse weather conditions.
When choosing a fertilizer, it is important to take into account the specific nutritional needs of the plant and choose a product with the appropriate NPK values. For example, if you want to stimulate leaf growth, you can choose a fertilizer with a higher nitrogen content, while if you want to stimulate fruit production, you can choose a fertilizer with a higher phosphorus and potassium content.

3. The best fertilizers for potted olive trees
There are several types of fertilizers that can be used to grow potted olive trees, and each has its own advantages and disadvantages. The three main types of fertilizers for potted olive trees are described below.
3.1 Commercial fertilizers
There is a wide variety of commercial fertilizers available on the market that can be used to grow potted olive trees. These fertilizers are available in different formats such as liquid, granular, slow release, and quick release.
For potted olive trees, it is recommended to use slow-release granular or liquid fertilizers, as these provide a constant supply of nutrients to the plant without the need to apply them frequently. When choosing a commercial fertilizer, it is important to ensure that it has the proper balance of nutrients, such as N-P-K, to meet the nutritional needs of the plant.
3.2 Organic fertilizers
Organic fertilizers are an excellent option for growing potted olive trees, as they provide nutrients gradually and naturally. Some of the best organic fertilizers for potted olive trees include compost, manure compost, worm compost and fish compost.
These fertilizers provide a large amount of nutrients, including nitrogen, phosphorous, and potassium, as well as other essential nutrients that are necessary for plant growth and development.
3.3 Homemade fertilizers
It is also possible to prepare homemade fertilizers for potted olive trees. One of the most common is tea leaf tea fertilizer, which can be made by soaking tea leaves in water for a few days and then spraying the resulting liquid on the roots of the plant.
Other homemade fertilizer includes rose water, which can be made by soaking rose petals in water for a few days. Both are excellent options for adding nutrients to the plant without the use of chemicals.
4. Fertilization of Olive Trees in Pots
Fertilization is an important aspect to maintain the health and growth of potted olive trees. So far, we have discussed the different types of fertilizers available and how to interpret their NPK values. In this section, we will delve into how, when and how often to fertilize potted olive trees.
4.1 When to Fertilize Potted Olive Trees
The appropriate time to fertilize potted olive trees is in spring and autumn. In the spring, the compost provides the necessary nutrients for growth and the production of flowers and fruits. In the fall, compost helps strengthen the roots and prepare the plant for winter.
It is important to keep in mind that fertilizing at inappropriate times can be detrimental to the plant. For example, fertilizing in the summer can encourage excessive leaf growth at a time when the plant needs to conserve energy to survive the heat. Also, fertilizing in winter can be inefficient due to the decrease in plant activity during this period.
4.2 How to Fertilize Olive Trees in Pots
The process of fertilizing potted olive trees is quite simple. The first thing you should do is choose the right fertilizer, following the recommendations that we have mentioned above. Next, you need basic tools like gloves, a basin, and a watering can.
To fertilize, simply add the fertilizer to the surface of the soil around the plant, followed by a layer of soil. Then, water sparingly so that the fertilizer works into the soil. It is important not to water too much to avoid waterlogging in the soil, which can cause an accumulation of salts in the roots of the plant.
After fertilizing, it is important to ensure that the soil is well drained and that there is no pooling of water around the roots. If necessary, you can place a layer of stone or gravel around the plant to improve drainage.
4.3 How Often to Fertilize Potted Olive Trees
The frequency of fertilization depends on several factors, such as the size of the plant, the age and the quality of the soil. In general, it is recommended to fertilize potted olive trees every 4 to 6 weeks during the growing season, which is usually spring through fall. It is important not to overdo the amount of fertilizer, as this can damage the roots and affect the growth of the plant.
However, it is advisable to carry out a soil analysis before fertilizing, since this can indicate if it is necessary to increase or decrease the frequency of fertilization. In addition, it is also important to monitor the health of the plant and observe if it shows signs of nutritional deficiencies, which would indicate the need to increase the frequency of fertilization.
In summary, the fertilization frequency of potted olive trees must be regulated according to the needs of the plant, but in general it is recommended to fertilize every 4 to 6 weeks during the growing season.
