- Overwatering or underwatering: Olive trees should not be overwatered, although they do require regular irrigation. The roots will rot, and the foliage will turn yellow in wet soil. On the other hand, the leaves will also turn yellow if the soil is very dry.
- Nutrient deficiency: To thrive, olive trees require a variety of nutrients, such as nitrogen, phosphorus, potassium, magnesium, and iron. The leaves will turn yellow if the tree is not receiving enough of one or more of these nutrients.
- Pests or diseases: Olive trees can be susceptible to a number of pests and diseases, including olive scale, olive leaf spot, and olive knot. These pests and diseases can cause the leaves to turn yellow.
Yellow Leaves on Olive Trees. In the pursuit of nurturing vibrant and healthy olive trees, it’s not uncommon to encounter the frustrating sight of yellowing leaves. This phenomenon, although distressing, is a natural response to various factors that can impact the overall health of your olive trees.

However, we aim to provide an even more comprehensive understanding of the issue, coupled with effective remedies to help you maintain thriving olive trees that stand out in your landscape.
Why Olive Trees Commonly Develop Yellow Leaves
Yellowing leaves on olive trees can be attributed to a range of causes, each influencing the tree’s health differently.
- Watering Imbalance: Often, the roots of olive trees can be quite sensitive to overwatering or underwatering. If the top 1-2 inches of soil become excessively dry, the tree’s leaves may start to turn yellow.
- Nutrient Deficiency: Olive trees require a balanced blend of essential nutrients, including nitrogen, phosphorus, and potassium, for optimal growth. A deficiency in any of these nutrients can lead to leaf discoloration.
- Pests and Diseases: Insects like olive fruit flies and diseases such as olive leaf spots can weaken the tree’s ability to absorb nutrients, resulting in yellowing leaves.
- Improper Soil Drainage: Poor soil drainage can lead to root rot, preventing the tree from taking up nutrients effectively and causing yellow leaves.
Effective Steps to Counter Yellow Leaves
To address the concern of yellow leaves and ensure your olive trees flourish, consider implementing the following measures:
- Watering Regimen: Maintain a consistent watering schedule, ensuring that the top few inches of soil remain slightly moist. Use a drip irrigation system to provide water directly to the tree’s root zone, preventing oversaturation.
- Nutrient-Rich Soil: Test the soil to identify any nutrient deficiencies. Amend the soil with a balanced fertilizer designed for olive trees to provide the necessary nutrients for healthy growth.
- Pest Management: Regularly inspect your trees for signs of pests or diseases. If detected, employ organic pest control methods to protect your olive trees without harming the environment.
- Optimal Drainage: Improve soil drainage by adding organic matter to the soil, enhancing its structure. This promotes healthy root growth and prevents waterlogged conditions.
