What to Look for in the Best Fertilizer for Olive Trees in Pots?

In standard cases, olive trees need a fertilizer containing high source nutrients, in particular nitrogen. Your tree will benefit from a nitrogen-rich fertilizer or source of Nitrogen or balanced N-P-K fertilizer.

You can find the information about the nutrient ratio of N-P-K fertilizer on its label. So you can look at this ratio and determine the percentage, by weight, of the nitrogen (N), phosphorus (P), and potassium (K) in the fertilizer.

The established olive tree requires a balanced fertilizer with a 20-10-10 formula. For example, a 1-pound bag of fertilizer would contain the following: 0.2 pounds of nitrogen, 0.1 pounds of phosphorus, and 0.1 pounds of potassium. As well, the balanced fertilizer has some micronutrients in it including magnesium, manganese, iron, copper, zinc, and boron.

If your olive tree in a pot has pest problems, you may want to try a popular Neem oil (link below). This organic oil is very good to protect your olive tree from pests or diseases and use it as a prevention.

Important to know, before choosing a fertilizer you should carry out a soil test and leaf analysis to know exactly what olive tree needs. By doing that, you learn what minerals your potted olive tree needs. Firstly let’s look at what benefits each macro or micronutrient brings to your olive tree in a pot.

Always the great option is a balanced fertilizer suitable for olive trees which contains nitrogen, phosphorus, and other nutrients

Why Nitrogen, Phosphorus, and Potassium is so important for Potted Olive Trees?

Nitrogen (N) is one of the main essential nutrients for olive trees. Its main responsibility in a potted olive tree is vegetative growth. Nitrogen constructs amino acids in the olive tree which are the building blocks for protein. As well, nitrogen is a major component of chlorophyll and helps to make the foliage green. And it is also necessary for the plant’s enzymatic reactions (i.e. active growth).

Another important nutrient for olive trees is phosphorus (P). It is a component in DNA and RNA (the genetic building blocks within plant cells) and is needed for root growth and flowering.

Last but not least is nutrient potassium (K). It works more indirectly than the other two nutrients. Potassium is not an element of any tree parts but activates many of the enzymatic reactions that occur within the plant, making it vital for overall plant health.

How Micronutrients Benefit Your Olive Tree?

Magnesium forces the movement of carbohydrates from leaves to other parts of the olive tree. It is a great help for the olive fruiting stage.

Another micronutrient manganese is involved with photosynthesis, efficient use of Nitrogen, protein metabolism, and enzyme activation. It will increase yields when applied on both soil application and foliar sprays.

If your tree has iron, manganese, and zinc deficiencies, usually it appears as lighter splotches between the veins of a leaf.

Boron is involved in many enzyme systems of your olive tree (in carbohydrate metabolism and translocation). It works like calcium and has a significant role in cell structure and cell wall integrity.

How to Use TreeHelp fertilizer?

For the potted olive tree, use only about 1/4 cup on a tree with it gently worked into the top inch of the soil. 
With potted trees, it is best to use less but replenish it more often due to the higher level of nutrient leaching via the pot. 
If you move the tree indoors in the fall, fertilize it after the move, to help it handle translation shock. Same as in the spring, moving the tree outdoors.
With the potted trees, as the fertilizer breaks down, replenish as needed, normally add a little every 2 to 3 months, as it is a slow-release fertilizer.

FAQs on Fertilizers for Olive Trees:

Why Do You Need to Feed Olive Trees in Pot?

Fertilizing olive trees follows the typical protocol growers use to keep olive trees and other plants healthy, strong, and pest free.

Indeed, strong and healthy olive trees are the product of good management practices. Particularly, proper fertilization for potted trees. As a result, strong healthy trees will produce more fruit.

How Often Should You Feed Olive Tree in Pot?

Olive trees in pots are heavy feeders comparing to wild olive trees due to their root restrictions in the pot. So it is best to fertilize them every 4-6 weeks during their active growing season (spring and summer). And every 1-3 months during the dormant period (fall and winter).

If you are using a liquid option you need to follow the recommended doses on the package. In most cases, it is once every 2 weeks. If possible, I do not recommend using a granular plant food for potted olive trees unless it is specialized for olives and you follow the brand instructions in terms of quantity and frequency. Because it can easily overfeed your olive tree since it grows in a limited area in the pot. However, there are no restrictions to use it for olive trees growing outdoors in the soil.


When to Apply Chosen Best Fertilizer for Olive Trees in Pots?

Apply fertilizer early in the spring to boost new growth and then repeat every few weeks. 

To know the best time frames of the fertilizing activities for your potted tree, observe the physical appearance and growth. If olive tree leaves look grey-green, the tree looks lush and is holding onto olive fruit, this means you do not need to fertilize the tree as often.

If your olive tree looks healthy, but you fertilize it too often, it can affect the flowering stage and production of fruits. However when olive tree flowers, it is the most nutrient-hungry stage and it’s good to feed your olive tree following fertilizer instructions. This will ensure the olive tree has enough nutrients to harvest well.

How to Fertilize Olive Tree in Pot?

The first way of fertilizing a potted olive tree is done through its leaves. Another way of fertilizing olive trees in pots is through the soil. The way of fertilizing depends on the type of product. It can be sprayed with fertilizers, granules, and spikes.

When you purchase an olive tree fertilizer, read and follow the product instruction on how to use the product. The directions will be to either spray the fertilizer onto the leaves of your olive tree or spread it out around the soil in the pot.

For olive trees in pots, I do not recommend spikes. No matter it is easy to apply but it can overfeed the tree because its roots have limited space in the pot and it can burn.

Organic vs Synthetic Fertilizers for Olive Trees in Pots

Synthetic fertilizers usually have higher amounts of the primary nutrients. And as they are easily water-soluble, they are fast-acting, producing impressive results in a short period of time. A great thing that most of them are blended and formulated for specific tree needs. However, incorrect or over-application may burn olive trees due to high concentrations of chemical nutrients, which are salts.

Organic fertilizers derived from organic sources provide benefits to both olive trees and soil over time to have better composition, texture, structure, drainage, and aeration. Organically derived fertilizers typically have a lower NPK analysis (nitrogen, phosphorus, potassium) than synthetics fertilizers, but they feed olive trees for a much longer period of time. As a result, the impact of organic fertilizers on olive trees may take a little longer but the reward is a tree and soil that stays balanced longer.

Final Takeaway: 

For fast, problem-solving, and impressive results at an economical price synthetic fertilizers are hard to beat.

But if you’re trying to build your soil for the long term, or you’re into organic gardening, then organic fertilizer is the way to go.

Placing crushed eggshells inside the pot of your olive tree is a great way to give natural organic nutrients. Even with a small quantity, it will help to boost the growth of your olive tree.

  1. June Perkins

    My sweet olive tree is in the ground. I live in Louisiana, notice there is moss on all of the branches and not many leaves. Do you know what the problem might be?

  2. Hi June, sorry to hear your tree has some problems. Let’s try to help to revive it.
    First, prune out the dead branches and all the leaves and twigs in the center of the tree, because they’re going to die anyway (lack of light,) and pruning them out allows more light to reach the outer areas of the tree.
    Secondly, check the soil moisture with a moisture meter. If the soil is too dry, many of the falling leaves will be yellow and start drop. If most of the leaves are green, but dropping, the soil may be too wet. Check the soil moisture by testing it and then follow other steps in my guide on how to revive the olive tree.

  3. Can I use natural fertilizer on my potted olive eg worm tea , liquid horse manure ?

  4. Can I use natural fertiliser on my potted olive, eg.worm tea, liquid horse manure.

  5. Hi George, yes, you can apply natural fertilizers, i.e. liquid horse manure which is a great source of slow-release nitrogen. Please read instructions carefully prior to using it for your tree as not to over-fertilize and damage a tree. However, do not use fresh natural fertilizers such as fresh horse manure – it can damage or kill your olive tree especially if it is a young tree due to high nitrogen concentration. Hope it helps. Happy olive tree growing!

  6. Can I use citrus tone fertilizer for my potted olive tree? I use it for my lemon tree and it says avocado and citrus fertilizer? But I’m not finding a list of other plants that it works for?. Other suggestions would be great if that’s not an option. Thank you

  7. Hi Maria, usually standard citrus tone fertilizers are high in nitrogen and suits for not only lemon trees, but nut trees, olive trees, and other plants. If on the label of your fertilizer is written that it works for citrus and avocado trees, then it should be absolutely fine with olive trees as well. For example, Espoma organic citrus tone works for all subtropical trees that like acidic soil: lemon, olive, fig, avocado, mango and others. Most important not to overfertilize. Happy growing! If you are interested in an olive tree growing and would like to ask questions or share pictures, recently I have created a Facebook community group you can join!

  8. Hi, I have an olive grove, but my seedlings rot and dry out. What fungicide should I use for this?

  9. Hi Hossein, sorry to hear your seedlings rot and dried out. It can be many reasons why it has happened. Poor drainage, overfertilization, root exposure to harsh temperatures, and so on. Any ideas in your case? First, you need to identify the root cause and then manage the treatment. Initially, the soil test would do a job. If it is root fungi, then you should diagnose the type of fungi or disease and apply a proper fungicide. Without a diagnosis, some fungicide may cause more damage to the roots than do good. If it is a fungal rot, then leave treating fungal infections to the local professionals. Only with further analysis it is difficult to apply the treatment and remove the cause.

  10. I bought TreeHelp Complete Fertilizer for my little potted indoor olive tree (cannot plant it outdoors due to Canadian winters). The instructions that came with it are for large outdoor olive trees. The package included the fertilizer, mycorrhizal treatment, and biostimulant. I just need to know measurements…how much should I be using and how often.

  11. Hi Patricia, you can always use granular fertilizer for potted plants even if the instructions point to trees planted in the ground only. As for this granular fertilizer, use 1 teaspoon per gallon (4 liters) of the soil. Sprinkle it around the tree trunk and deep water afterward. Fertilize every 3 months excluding the winter season. Hope it helps!
