Compost tea is an effective and environmentally friendly solution for pest control in gardens and farms. By enhancing plant health and resilience, it naturally reduces pest populations without the need for harmful chemicals. This makes it a popular choice for gardeners looking to maintain a healthy ecosystem.
What Is Compost Tea and How Does It Work?
Compost tea is a liquid solution made by steeping compost in water, which extracts beneficial microorganisms and nutrients. These microorganisms, including bacteria, fungi, and protozoa, help improve soil health and plant vigor. By applying compost tea to plants, you can enhance their natural defenses against pests.
