Utahns are facing a challenging year ahead due to the ongoing drought, but there are practical steps they can take to help their yards survive. The key is to embrace water-wise landscaping, which can significantly reduce water usage without compromising the beauty and functionality of their outdoor spaces. This approach is particularly crucial as Utah water managers urge residents to delay turning on sprinklers and drip systems this spring, anticipating another hot and dry summer along the Great Salt Lake and Colorado River.
Katie Wagner, a horticulture expert with the Utah State University Extension, emphasizes the importance of moving beyond the concept of 'zero-scape' and embracing 'xeriscape' or 'dry landscaping'. This involves more than just covering the ground with rocks; it's about creating a sustainable and visually appealing outdoor environment. By adopting water-wise practices, Utahns can contribute to water conservation efforts while maintaining their yards' health and aesthetics.
One significant development in recent years is the state's requirement for community associations to develop water-wise landscaping regulations. This change has empowered residents in homeowners associations (HOAs) to make more sustainable choices for their yards. Trever Midgley of HOA Solutions highlights that HOAs can no longer ban xeric landscaping, require turf in narrow areas, or mandate excessive water usage during droughts. This shift has resolved past disputes between homeowners and HOAs over artificial turf and lawn removal, allowing residents more freedom in their landscaping decisions.
Despite the benefits of water-wise landscaping, some may wonder why vegetation is essential during droughts. Wagner clarifies that maintaining plants provides environmental advantages, even in extremely dry and hot conditions. Turf, for instance, plays a vital role in protecting soils, retaining moisture, and mitigating urban heat-island effects. She dispels the myth that overwatering and fertilizing are the only ways to keep turf green, explaining that temperatures above 80 degrees trigger dormancy, and as little as a quarter inch of water per month is sufficient for turf survival.
For those considering a complete lawn removal, Wagner suggests exploring alternative groundcovers like low-growing oregano and creeping Oregon grape. She also recommends mixing turf with low-water groundcovers such as clover and yarrow, which have gained popularity for their aesthetic appeal and water efficiency. However, she cautions against neglecting the water needs of existing shrubs and trees, as mature plants provide shade, habitat, and essential ecosystem services.
Given the challenging water outlook, Wagner advises Utahns to hold off on adding new perennials or lawns until the fall. This decision ensures that new plants won't require excessive water during the hottest months. Additionally, attending the monthly online webinar 'Urban Conserver' hosted by USU Extension and the Jordan Valley Conservation Garden Park can provide valuable insights into maintaining a low-water landscape.
In conclusion, embracing water-wise landscaping is a practical and responsible approach for Utahns to help their yards survive the drought. By adopting sustainable practices and making informed choices, residents can contribute to water conservation while enjoying the beauty and functionality of their outdoor spaces.
