Species selection is key when choosing trees for the city of St. George, as the species you choose will determine which trees flourish and which fall by the wayside. When it comes to trees that flourish, species better adapted to the region should be used. The majority of the city is located in Zone 8b, which means that temperature extremes with very hot summers and very cold winters are a given. Based on the climate, trees with a narrow temperature range will not do well in St. George. A good tree care service in St. George will select species better adapted to local conditions.
What Makes St. George Hard on Trees
St. George sits at the Colorado Plateau’s edge with the Mojave Desert, which places it in Hardiness Zone 8b. Many trees sold at local nurseries can’t handle winter lows of 15°F or summer highs that reach and surpass 100°F. A reputable tree care service starts by selecting species suited to local conditions.
Top Trees That Work for St. George Backyards
The following are five trees that will thrive and flourish in your southern Utah yard.
Desert Willow (Chilopsis linearis)
The native desert tree of southern Utah that deserves a place in every yard. These trees are hardy and can handle rocks and dry soil well. They even have the potential to add color to your yard with their trumpet-shaped blooms in the late spring through fall. With an average height of 15 to 25 feet, this tree is ideal for mid- to large-sized residential properties.
Desert Museum Palo Verde (Parkinsonia hybrid)
Desert Museum Palo Verde trees put on a stunning show in spring with bright yellow flowers against dark green foliage. They remain substantially green in summer, but only about half their leaves may be present. They are hardy and resistant to root rot, so their water is reserved during summer. The trees provide filtered shade due to their light foliage.
Arizona Ash (Fraxinus velutina)
These trees are a favorite in landscape design, especially in the hot summer months of the Southwest. They provide good shade and look brilliant as their leaves change to a bright gold in the fall. Deep watering in the first year helps them achieve a healthy root system. It’s best to hire a tree care service to adjust the watering timer.
Utah Juniper (Juniperus osteosperma)
These trees are perfect for someone looking for a low-maintenance option. They are highly resilient to soil and weather, with silvery-green foliage that is nicely structured and requires minimal upkeep.
Honey Mesquite (Prosopis glandulosa)
These trees actually help the ecosystem by fixing nitrogen. This is perfect for a landscape that values conserving water, and they actually help the soil over time.
Planting Practices That Pay Off
The best time to plant in St. George is during the Fall or Spring, because when the Summer and Winter extremes arrive, the trees will have a well-established root system. Mulch reduces moisture loss, and roots will grow deeper if watered at longer intervals. Due to St. George’s clay and sandy soils, compost will greatly improve the quality of plantings. A good tree care service in St. George will assess and advise on the best conditions for each tree species at your property.
Create a Yard That Lasts
Choosing species is only part of the process. The depth for each species, how you set up your irrigation, and how often you prune your trees will all factor into how well your trees establish and how long they will last. St. George is not the easiest to work with, but it’s not the worst either. With the right species, along with the assistance from a knowledgeable tree care service in St. George, and the right trees, you can have a thriving landscape for decades instead of just a few summers.
