For the past several decades, xeriscaping— or creating an outdoor space that doesn’t require a lot of irrigation—has been a popular way to create a beautiful landscape without relying on an abundant water supply. Clean, safe water is a limited resource that animals, plants and humans alike need in order to grow and thrive, so it makes sense to limit its use in dryer areas like in large portions of Utah. Despite its many advantages, xeriscaping can be a hard sell to people and corporations who love the look of a lush, green lawn.
Xeriscaping is often thought of as a sparse landscape with few to zero plants— but xeriscaping is about so much more than sparse planting and an overabundance of rocks. There is no official water use threshold that defines when a landscape becomes a true xeriscape project. The spirit of this kind of landscape design is to limit the impact of an outdoor space on its surrounding environment.
Here are four things to consider when incorporating xeriscaping into a residence or corporate environment, each allowing for less water without sacrificing plant options:
- Water recycling
For some projects, large trees or lush vegetation are a necessity. Whether
for privacy, oxygenation, shade or for structures like treehouses, larger
plants can add a lot of value to the space they’re in. However, they often
use a lot of water. Recycling is one way to offset the high impact on the
environment. Rain can be collected and used in irrigation systems.
Innovative water features can even use pumps to recycle rainwater or
runoff. Additionally, features like rain gardens and permeable pavers help absorb water and return it to the soil.
- Local plants
A basic principle of xeriscaping is that plants should be acclimated
to the local climate. The reason local plants use less water is that
they’re already adapted to the soil and hydrology of the region. Native
plants have evolved to survive in the area without human intervention,
so they can continue to thrive with natural rainfall and weather
patterns. Not only do local plants generally require less water, they
usually need less maintenance and fertilizer as well, so planting
them can save money and reduce the amount of chemicals that seep
into the ground. Native plants are naturally great for native species like
birds and pollinators, too.
- Redefining turf
There’s no need to give up a manicured greenspace in pursuit
of an environmentally-friendly landscape design. Project managers
and clients just need to adjust their conception of what grass looks
and feels like. There are a variety of grasses available that will add that
soft, green feel to an outdoor design without draining the local water
reservoir. A promising specimen is the turf-type tall fescue. New
cultivations have a strong green color with deeper roots and a higher
drought tolerance. Turf-type tall fescue uses up to 30-percent less
water than traditional bluegrass, so it’s a great option for xeriscaping
when used in moderation.
- Unconventional choices
A well-balanced landscape is about more than just plants. Play spaces,
synthetic turf, lounge areas, fire pits, hammocks, sandboxes, paths,
swinging benches and large outdoor games are all alternatives to water-using plants. Creative solutions like these add usable, beautiful touches to a planned landscape project without using more water. By reframing the ideas and philosophy of what landscape design has to be, landscaping can both look green and be green at the same time. The EPA estimates
that 30-percent of the water the average American family uses is devoted to outdoor application. Utah is not only one of the driest states in the nation, it’s one of the fastest-growing. Wise water management is a key strategy to help keep the Utah economy strong.
