Essential Oils in the Garden
When we use essential oils on our bodies, we use them 3 ways- aromatically, topically, and internally. We can use them in similar ways on our plants.
Sprays: Add drops of essential oil to water in a spray bottle. Add a few drops of natural liquid soap such as castile soap to act as a surfactant, which will ensure uniform coverage on leaves and insect bodies. Spray directly onto fruits, vegetables, flowers, etc.
String: Soak a string in a mixture of water and essential oils. Hang the string between crops in the garden. This will deter flying insects.
Cloth Strips: Use a drop of essential oil on strips of fabric and hang throughout the garden. Add more drops as needed.
Cotton Ball: Use for animals or pests that like to burrow. Place directly on top of nests, burrows, etc.
Cartons & Containers: Bury the carton into the ground up to the top of the container. Add drops of essential oil to deter slugs, snails, mice, ground insects, etc.
Here are a few recipes to try. Remember that essential oils are powerful. Apply sparingly. Several applications, every few days may be necessary:

8 oz. Water
Couple Drops of Pure Liquid Castile Soap
Combine ingredients in a spray bottle. Spray the leaves, including underneath. Apply with a brush if you want to be more specific in application.
General Plant Protection
5 Drops Lavender
5 Drops Thyme
8 oz. Water
Combine ingredients. Use a spray bottle to mist the plants.
Mildew & Fungus Spray
1 Teaspoon High Proof Alcohol (alternatively, leave this out and add 1/2 tsp. of Baking Soda dissolved in the water.)
6 Drops each Melaleuca, Oregano, Thyme
8 oz. Water
Combine the first two ingredients. Shake to incorporate. Add water to oil mixture and place into a spray bottle. Spray in the evening when the sun cannot burn the leaves.
