How to Use Essential Oils for Gardening
Take 4-6 drops of essential oil in a spray bottle. Fill it 3/4th with water, and your mixture is ready! Remember to shake the bottle before every use. For best results, spray the plants early morning or evening, as the cool atmosphere helps in quick absorption.
Insect Deterrent Spray
Use a large spray bottle and add 1-2 drops peppermint, rosemary, and thyme essential oil. Fill it half with water. Mix well and use it early morning or evening.
Fungus Spray (Powdery mildew, blight, etc.)
Take 3 liters (1 gallon) spray bottle and add one drop oregano oil, five drops tea tree essential oil, one squirt Castile liquid soap, three tablespoons baking soda, and fill the bottle with water. Spray the solution on plants once a week, in the morning or evening.
Essential Oil Weed Killing Spray
Take a spray bottle and fill it with distilled white vinegar (below the fill line), one squirt of Castile soap, 15 drops of clove essential oil, and ten drops of cinnamon essential oil. Shake well and spray this solution on weeds.
Note: Use it only on weeds and not on plants as it can kill them.
You can use cotton balls to prevent pests at the ground level. Soak cotton balls in any of the essential oils from the list and put near burrows or rodent nests. They can be used in the garden to attract pollinators as well.
Strings or Strips
If you don’t want to use spray, then strings or strips are a good option. Soak cotton strips in essential oils and hang from a tree branch and near plants. The smell of these oils can confuse insects and repel pests.
