Know Your Soils Booklet cover

The foundation of a healthy garden is healthy soil. 

Healthy and productive soil has a balance of nutrients and good structure that allows for ample microbial and plant growth. Building healthy soil takes time, even a few growing seasons, but there are ways to improve your soil and grow edibles and other plants at the same time. This booklet is your introduction to soil testing and using amendments to build healthy soil. We’ll start with a brief introduction to soil structure, and dive into soil testing, and choosing and using amendments and fertilizers to create productive, healthy soil. 

Remember, every garden is different. This booklet is your introduction to soil testing and using amendments to build healthy soil. Experiment with your garden, keep a journal, and observe over time which practices work and which ones do not. Good luck and happy experimenting!
