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 16-16-16 formula. For example, a 10-pound bag of fertilizer would contain the following: 1.6 pounds of nitrogen, 1.6 pounds of phosphorus, and 1.6 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.  

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.

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. 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?

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 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 Fertilizers for Olive Trees in Pots

Olive trees love organic fertilizers due to high nitrogen consistency. There are many different organic fertilizers such as blood meal, soybean meal, chicken or horse manure, cottonseed meals, and others. They are all excellent organic nitrogen sources, but you need to be careful applying it onto your potted olive tree.

For instance, fresh organic fertilizers such as chicken or horse manure for your potted olive tree is a risky option. Because fresh manure can damage your olive trees and even kill young trees due to dangerously high nitrogen concentration at this growth phase. To avoid any problems related to over-fertilization, you can prepare manure suitable for your trees by waiting a month before use in order to get rid of undesirable elements. Then, mix it with compost or potting soil for the best results.  As well, don’t forget that fresh manure has an unpleasant strong smell, so normally tree growers do not use it for indoor trees.

Are Coffee Grounds Good Fertilizer For Olive Trees in Pots?

Yes, coffee grounds are good for potted olive trees. If you have not heard yet, olive trees love acidic soil. So apply a coffee ground mulch or pine needles in your olive tree pot can help to acidify soil that has a low pH level.

Keep in mind the optimum pH level is 6.5 for olive trees. Always test your soil so that you are not adding too much acid.

Are Eggshells Good Nutrition for Potted Olive Trees?

Yes, eggshells are great for olive trees and other indoor plants. They are high in calcium and are easy to slowly feed it to your potted trees.

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.




Conclusion

Growing olive trees in pots at your home or in your yard has become so popular.  No doubt, olive trees themselves make a gorgeous addition to any landscape. They are beautiful ornamental with grey-green, shiny leaves and lovely olive fruits. Indeed, it can be an easy, productive venture when potted olive trees are properly fertilized.
