Learn to read what weeds, plants, and natural patterns reveal about soil health and ecosystem conditions.
Many people see weeds as problems to eliminate.
This is a growing educational series exploring how to interpret landscapes through the plants that grow there. Each article builds on the last, helping gardeners, farmers, and land stewards understand what nature is telling them.
This series explores a different perspective: weeds are indicators. They reveal information about soil compaction, drainage, fertility, disturbance, moisture, and ecological succession. By learning to recognize these patterns, you can better understand your land before making management decisions.
Whether you’re managing a backyard garden, farm, or restoration project, Reading the Landscape provides practical, research-based guidance for interpreting what plants are telling you.
