How to Use Essential Oils on Plants
Before we dive into the best essential oils for plants, it’s essential (pun intended) to understand how to use them safely and effectively:

– Start with small amounts: Begin with a small amount (about 1-2%) and gradually increase as needed, monitoring your plants’ response.
– Choose the right method: You can use essential oils through foliar sprays, soil drenches, or potpourri-style blends. Experiment to find what works best for your plants.
– Be mindful of timing: Avoid using essential oils during extreme weather conditions, when plants are stressed, or during peak sun hours.
