But challenging doesn’t mean impossible! Use our quick guide to make your search for Wyoming plants a breeze.
Where to Grow and Care for Wyoming Plants
Climate: Wyoming has a semi-arid and continental climate, making it drier and windier than much of the United States. When selecting a plant, ensure it is tough and can survive in USDA zones 3 through 6.
Soil: The state’s soil ranges from sandy to clay and is typically alkaline. Test your soil’s pH before planting, and then amend as needed. For instance, you will need to add an acidic fertilizer to grow blue Hydrangea.
Planting: You have one chance to plant your tree correctly, so do it right. Dig a hole that’s twice the width of the root ball. The depth should be no deeper than the height of the root ball.
Water: Your irrigation schedule depends on your area and the plant's needs. Generally, plants should be watered frequently until established. One tip to make watering easier is to group plants by water needs—for instance, plant low-water-use plants together and medium-water-use plants together.
