Save Water In Your
Yard
Despite our rainy winters, we
get less rainfall than Tucson, AZ during the summer months. That’s when
our reservoirs are lowest, and demand for irrigation water is highest.
Choosing drought-tolerant plants, building rich soil, watering wisely,
and following the other key steps below will help you…
-
Save money on water bills
-
Save time maintaining your garden
-
Protect your family’s health by reducing
the need for chemicals
-
Protect our environment
-
Grow a healthy, beautiful yard and
garden all year round!
Proper planning and preparation are necessary to achieve
water efficiency. Regionally, the Saving Water Partnership, in
conjunction with landscape professionals in our region developed The
Naturals, a series of brochures designed to assist customers in the
planning, preparation and maintenance of their landscapes. These
brochures are available for free in our office, as well as in our
brochure rack in our Waterwise Demonstration Garden. If you would like
to download them yourself, they are available online. We’ve described
each brochure below and provided a link to them for downloading ease.
There are also rebates available to help customers with existing or new
irrigation systems. Click on the link below to learn more about the
rebates. For more information call the Natural Lawn and Garden Hotline
professionals at 206-633-0224.
Landscape professionals tell us that
most people over-water their landscapes by as much as 200%. Learning
correct watering techniques not only reduces your water bill, but it
also conserves an important natural resource and improves the health of
your plant material. Check out our Smart Watering brochure to make
every drop count!
Growing
Healthy Soil
Did you know that by simply improving your soil, you can
beautify your garden, cut your water bill, improve water quality in our
streams, and even reduce your work? Growing healthy soil – and a
healthy garden – is as easy as adding compost and other organic
amendments to your soil. In fact, this is the single most important
thing you can do for your garden. Check out our Growing Healthy Soil
brochure to learn the steps you can take to improve your garden’s soil.
Choosing
The Right Plants
When you grow plants in the appropriate conditions, they
thrive with minimal care. By choosing plants well adapted to each
garden situation, you save time and money, reduce maintenance, help
prevent pests and diseases, and leave more clean water for salmon and
other wildlife. Plan now and enjoy the benefits for years to come. Our
guide will take you through simple steps you can take for choosing
plants that will flourish in your garden.
Natural
Lawn Care
Your lawn can be a great place to hang out, but depending
on how you care for it, your lawn can also be part of big environmental
problems. Healthy lawns grow on healthy soil. Using proper soil
preparation and lawn maintenance practices will help to build healthy
soil and vigorous, deep-rooted lawns. These lawns are more resistant to
disease, tolerate some insect and drought damage, and will out-compete
many weeds. The practices recommended in our Natural Lawn Care brochure
can help make lawns healthier for our families, protect beneficial soil
organisms, and protect our environment too.
Natural
Yard Care
Our yards are our outdoor homes: fun, beautiful, great
spaces for relaxing. But in taking care of them, we often use water
inefficiently, produce a lot of yard waste, and overuse chemicals that
are bad for the environment and our families’ health. The good news is,
by making some simple changes in how we care for our yards we can save
money, time and help the environment. Find out how in this introductory
brochure on Natural Yard Care. This brochure briefly explains the five
steps to Natural Yard Care and provides a seasonal task list to help you
get started.
Natural
Pest, Weed & Disease Control
Why manage your garden naturally? Insects, spiders, and
other crawling or flying creatures are a vital part of healthy gardens.
Most perform important jobs like pollinating flowers, recycling
nutrients and eating pests. In fact, less than 1% of garden insects
actually damage plants. Unfortunately, the pesticides often used to
control pests and weeds are also toxic to beneficial garden life – and
may harm people, pets, salmon, and other wildlife as well. This
brochure will walk you through the basic steps to create healthy plants
and soil that will not only resist pests and diseases, but also
encourage beneficial garden life.
Saving Water with Soaker Hoses
Soaker hoses are a great way to save water and keep
plants healthy. They slowly leak water directly into the soil, instead
of spraying it into the air and wasting water through evaporation.
Plus, they put the water in the root zone – right where your plants need
it – not on plant leaves where moisture can cause rust and other
diseases. Check out this fact sheet for information on buying soaker
hoses and installation tips.
Rebates
Cash rebates are available for sprinkler system tune-ups
and upgrades. Find out all the details of the rebate program and tips
on finding an irrigation professional.
ET
helps save water! So what is ET?
ET is the abbreviation used for the word
Evapotranspiration. Evapotranspiration is a term used to describe water
that is lost from the soil surface by evaporation or through the leaves
of plants by transpiration. ET is driven by weather factors that
determine the drying power of the air. We can accurately predict ET
losses in a given area from the measurements of four local weather
variables: (wind, solar radiation, temperature and humidity)
In 1995, the District added an Evapo-Transpiration (ET)
Weather
Station to our waterwise demonstration garden. The weather station came
with a Maxicom Jr. Computer Control System that is used to automatically
adjust our irrigation system to water only what is needed based on how
much has evaporated and transpired out of the soil and plant material.
According to landscape professionals, many consumers
over-water their lawns by as much as 100 percent. This results in
wasted dollars and is detrimental to the health of the lawn. Throughout
the country many landscapers use ET data to enhance their ability to
manage outdoor water use for maximum efficiency.
You Can Water Your Lawn Using ET too!
Many customers do not adjust their irrigation controllers
during the lawn-watering season. However, watering needs can be
significantly different in each month. By adjusting your irrigation
controller weekly, you could see significant water and dollar savings.
If you are ready to upgrade your controller, there are rebates available
for controllers that automatically adjust according to the weather.
Check out the rebates at
http://www.savingwater.org/outside_sprinklers.htm.
You can also calculate
how much water your landscape needs and how much to adjust watering
schedules throughout the season by visiting the 'Seattle Area' pages of
the Irrigation Water Management Society webpage
at
www.iwms.org. At their website you can:
- Consult the current Watering Index to adjust your water schedule
using the "Percent Adjust" or "Water Budget" feature found on most
modern controllers.
- Use the Water Budget Calculator to determine your landscape's
watering requirements.
- Create a customized watering schedule based on your plantings
and watering system with the Sprinkler Calculators.
What about your soil –
does it play a part in how you irrigate?
In addition to estimating the amount of required
irrigation water, it's important to also consider the type of soil and
the amount of slope that is found in the landscape. Soil type and slope
have a significant effect on the amount of water that can be stored in
the soil and how quickly the water can be absorbed. In general, sandy
soils quickly absorb water but hold the least amount of water; clay
soils hold the most soil moisture but absorb water at a slow rate. If
you need help in determining the soil texture of your landscape, contact
your local Extension Office for information on performing a basic soil
test. You can reach Washington State University King County Extension
office by calling 206.205.3100. They will send you a packet of
information that tells you how to take your soil sample, approximately
how much it will cost and where to send the sample.
Our hotline is changed daily to inform callers how much
water should be replaced in their lawns if they water daily, every third
day or weekly based on their soil type.
More Watering Tips for
a Healthy, Waterwise Landscape
-
Water early in the morning, between 4
and 10 a.m. Doing so allows the plant foliage to dry, making it less
susceptible to foliar diseases. Early morning watering also ensures
less distortion of sprinkler patterns and reduces evaporation due to
lower winds and cooler temperatures.
-
Create water zones by putting plants
together that have similar water needs. Doing so minimizes the
potential of over watering and under watering neighboring plants.
Where woody plants must be included in turf grass areas, consider
using water-loving or water-tolerant plants, which can remain
healthy under relatively high amounts of irrigation.
-
Irrigation for established woody
landscape plants should be focused at and/or beyond the drip line to
promote extensive rooting, and should be applied deeply into the
soil (water delivered deeper than the 2- to 3-foot range, however,
will not be accessible by most of the plant roots).
-
In new landscapes with automatic
irrigation systems, newly installed plants may not receive the
thorough watering required to promote early vigorous root
establishment; supplemental hand watering, therefore, may be needed
to provide the watering necessary (this is especially true for small
plants which may dry out quickly or large plants with deep root
balls).
Other Efficient Outdoor Water Practices
-
Wash cars using a bucket, sponge and
shut-off nozzle on the hose.
-
Sweep sidewalks, driveways and patios
instead of hosing.
-
Consider a wading pool for children
instead of letting them go through the sprinkler.
-
Clean gutters and downspouts manually,
without using a hose.
