To make oil spray for citrus trees, you create a concentrate of olive oil and detergent, which you then dilute with water before spraying. This solution helps deter pests by making the leaves less attractive for egg-laying.
Steps to Make Citrus Tree Oil Spray:
Here's a breakdown of how to prepare and use citrus tree oil spray:
-
Prepare the Concentrate:
- Combine 2 cups of olive oil with ½ cup of liquid dish detergent (avoid detergents with bleach). Mix well. This is your concentrated solution.
-
Dilute the Concentrate:
- For application, use 1 teaspoon of the concentrate per 1 liter of water. Mix thoroughly.
-
Application:
- Pour the diluted solution into a spray bottle.
- Spray all parts of the citrus tree, especially the leaves, ensuring good coverage. Aim for both the tops and undersides of the leaves.
- Apply in the cool of the day (early morning or late evening) to avoid burning the leaves in direct sunlight.
-
Frequency:
- Repeat the application every two weeks during the summer months, or as needed, if you notice pest activity returning. This is a preventative measure and won't harm the tree.
Important Considerations:
- Type of Oil: While olive oil is commonly used, other plant-based oils may work.
- Type of Detergent: Use a mild, liquid dish soap. Avoid using detergents that contain bleach, as these can damage your citrus tree.
- Test a Small Area First: Before spraying the entire tree, test the solution on a small area to ensure it doesn't cause any adverse reactions. Observe the area for 24-48 hours before proceeding with a full application.
- Coverage is Key: Thorough coverage is essential for the spray to be effective. Make sure to coat all leaf surfaces.
- Environmental Conditions: Avoid spraying on rainy days, as the rain will wash away the solution. Also, avoid spraying during extremely hot weather.
By following these steps, you can create an effective and safe oil spray to protect your citrus trees from pests.
