Central Oregon’s Water-Wise Gardening
It’s called the high desert for a reason. In Central Oregon, an average year of precipitation is between 12 inches and 20 inches, the majority of it in snow. It’s dry, it’s cool at night, and frankly, it’s not a place that’s particularly suited to a lush, green lawn.
That’s why so many people are getting on the xeriscaping bandwagon. Xeriscaping is growing in popularity in the dry climates of the American West, and the City of Bend is part of the movement. Earlier this year, Bend landowners were offered a Turf and Removal Rebate, consisting of $3 per square foot up to $3,000 for projects that replaced lawns with water-conserving xeriscaping. About 60 percent–4.5 billion gallons—of Bend’s water goes to landscape irrigation, most of which is residential.
According to Dan Denning, the city’s water conservation program manager, the funds for the rebate program were allocated within three weeks. “With more frequency of extreme drought and the variability of how we’re getting our precipitation–like these summer deluges where we’re getting a few inches an hour–and in the growth we’re experiencing, we’re seeing a shift in how much water we use and when we’re receiving the water,” he said. “So for us, it’s a strategy for trying to keep up with population growth.” Whether incentivized by a city rebate, or with water conservation in mind, xeriscaping can be accomplished with simple steps.
Where to Start
Homeowners may not know where to start a xeriscaping project or worry that their new landscaping will be a big pile of rocks. One of the biggest misconceptions, Denning said, is the idea that Bend will end up looking like a rockscape. He said plant material and mulch is vital to a good-looking xeriscape project. The lushness created by selecting the correct plants also has a cooling effect. A landscape of many rocks actually radiates heat, and the plants will require more water, he explained.
It doesn’t have to be all sagebrush, either. There are plenty of pretty, green native plants that bloom.
Denning understands the temptation of a lawn. “We continue to put grass down because it’s cheap, and it’s what we know,” he said. “We know how to mow a lawn and what it should look like. Xeriscaping is uncharted territory for some people.”
A Seven-Step Process
Xeriscaping just a small area of your yard can make a difference. Pick an underused area or a spot where your lawn is already looking a little shabby. Then, consider potential areas for use, maintenance goals and how much sun the area gets each day: does water already flow to that area of the yard? How will you irrigate it? Consider irrigation controllers that use sensors and adjust the amount of water used depending on the weather. Ensure your soil is healthy and rich in nutrients. Then it’s time for the fun stuff–deciding how much turf to keep and picking out the right plants for the new xeriscaped space.
Plants in the Xeriscape
The Oregon State University Extension Service offers an excellent guide to selecting plants for xeriscaping. Its recommendations include grouping plants that require similar amounts of water and sunlight together, and incorporating plants that provide different functions to create a diverse landscape. From ornamental chokecherry trees to fescues and phlox, there are plenty of plants that require little water but make a big impression. Bonus: The more diverse the plants in your landscape, the more varied the animals and insects attracted to them, making the environment even healthier.
And don’t forget the mulch. It prevents water from evaporating, counters erosion and cools the soil. An added bonus? Mulch will also cut down on your weeding time.
Start small. “You can do more than you think,” Denning said. Whatever you do will make a difference. Need more ideas on how to conserve water while creating a beautiful landscape? See waterwisetips.org.
