"Regularly using a soil drench is an efficient way to keep both plants and soil healthy. It’s as easy as watering your plants, and you can use a soil drench to address pest infestations, maintain soil and plant health and prevent pests and diseases from overwintering and causing issues next season.

I highly recommend using neem oil because it is natural, defends against a wide variety of pests, bacteria, fungi, and all development stages of insects.

Reduce your use of chemicals with knock-down power by utilizing the sustained power of soil drenches. Give it a go. You might like it enough to form a habit."
