Unlike a lot of other types of trees, olive trees do not need a special form of fertilizer to be able to grow and thrive. Instead, results will be significantly better simply by following a good nutrition regimen.
If the trees are planted after mid-August and before March 1, it’s better to wait until spring to fertilize (though because our groves are located in warmer areas, we can be the exception to this rule). Otherwise, fertilization begins immediately after planting and occurs regularly throughout the growing season. How regularly depends on the type of fertilizer being used. For best results, fertilizers with a nitrogen analysis of 10 percent or more are recommended.
Types of fertilizers commonly used for olive tree growth include:
• Fast-release fertilizers. These fertilizers often contain minor elements and are generally the most widely available forms of fertilizer. When using this fertilizer, you should water the plants liberally. This type of fertilizer is not meant to be used for trees that are still in their pots.
• Liquid fertilizers. While liquid fertilizers can be used and produce decent results for olive trees, they’re generally not recommended because of the fleeting nature of liquid feeding. It must be repeated quite often, which would eat up a lot of time growers could spend on other aspects of plant care.
• Organically derived fertilizers. While these types of fertilizers are more expensive and might not contain the percentage of nitrogen often preferred by olive trees, they are widely available and still produce decent results.
Whatever type of fertilizer the grower uses, it is generally a good idea to feed lightly but often throughout the growing season. Heavy applications of fast-release fertilizer could actually damage the plant or run off into groundwater. If you follow the instructions on the label of the fertilizer you should be fine.
This is just a quick overview of the surprisingly complex topic of fertilization for olive trees. For more information about the processes we use to grow our trees and harvest our fruits, contact us today at My Olive Tree.
Our mission is to create a partnership between the Evangelical community and the nation of Israel; this partnership will produce employment, income, and revenue for humanitarian aid projects in Israel. We envision the planting of one-million olive trees over the next seven years. This relationship was prophesied in the Bible centuries ago, that the foreigners and strangers (those not of Jewish descent) would help rebuild the walls of Israel and cause the desert to bloom (Isa 35:1). Among other things, this reforestation is an environmental blessing for the entire region. May all who participate in this project be blessed body, soul and spirit; it is time for you to take root in Israel!
