Using Olive Oil in Garden

Olive oil could be helpful for your plants as it protects them from stubborn pests and provides essential vitamins like Vitamin E, which increases the plant’s survival in cold weather.

1. Clean Plant Leaves

Take 3-4 wee bit drops of olive oil on a damp cotton cloth and wipe the leaves—it will gently lift off the dirt and debris while leaving a layer of shine! Ensure you are not leaving the plants in the sun after doing this. Otherwise, it will burn the foliage. Also, you may need to wipe off the leaves again with just a clean cloth to remove the layer of oil (if it sticks).

Cleaning the leaves with olive oil also helps eliminate scale insects. You can do this once or twice a month.

2. Eliminates Leaf Miner

The leaf miner eats the tissue of the foliage and leaves ugly white marks behind. If unattended, it can cause severe damage to the leaves. Olive oil is a natural leaf miner killer.

Make your own leaf miner killer at home by mixing two teaspoons of olive oil and one teaspoon of mild dishwashing liquid in a liter of water. Transfer it into a spray bottle, shake well, and mist on the affected areas of the plant. Before spraying it on your plant, do a patch test on several leaves to see the reaction the next day, and also avoid spraying it when the sun is intense.

3. Pest Control
