Best Soil for Gardening in Wyoming

Wyoming

Wyoming has 43 USDA soil survey areas, and they vary considerably in how friendly the ground is for growing things. We ranked every survey area by the percentage of well-drained soil — the single most important soil property for most garden plants.

At the top, Campbell County, Wyoming, Northern Part has 99% well-drained soils — conditions where most vegetables, herbs, and flowers can thrive with basic soil preparation. At the other end, Goshen County, Wyoming, Northern Part comes in at 67%, meaning more of the landscape has drainage challenges that may require raised beds, soil amendments, or careful site selection for a productive garden.

Remember that these are area-wide averages. Even in a low-ranking survey area, individual properties can have excellent garden soil. Look up your specific address for exact conditions.
