The Basics of Foliar Watering

Foliar watering, also known as leaf watering, is the practice of spraying water directly onto a plant's leaves. This technique has been used for decades, and its benefits are still debated among plant experts. But before we dive into the pros and cons, let's explore how foliar watering works.

When you spray water on plant leaves, the water is absorbed through tiny openings called stomata. These openings are responsible for gas exchange, allowing plants to breathe in carbon dioxide and release oxygen. As the water is absorbed, it's distributed throughout the plant, providing hydration and potentially boosting growth.

Benefits of Spraying Water on Plant Leaves

So, does spraying water on plant leaves really help? The answer is yes, but with some caveats. Here are some benefits of foliar watering:
