FROM THE ARCHIVES: Successful Drought Tolerant Gardening, Let’s Talk Plants! February 2009, No. 173


View from above Cindy Spark's backyard which she re-did according to some of the principles presented in the Successful Drought Gardening series.

Edited by Cindy Sparks.


This kicks off a year-long series of articles on:


· Why water conservation is important.

· How a drought tolerant garden can be good for you, the birds and bees, your water bill and your property value.

· Setting a water use goal.

· Identifying your requirements to meet your goal, including cost, time, and labor limitations.

· Planning a drought tolerant landscape.

· Picking plants that will succeed in your growing conditions.

· Installing and establishing your new landscape.

Why Water Conservation is Important -

A gentle rain is falling as I write this kick-off article on gardens that conserve water and respect our environment. Most landscapes are not yet sustainable. As you read the articles, take a fresh look at your landscape and its impact on our planet.


In past years, plentiful, low cost water encouraged us to use too much. Most landscapes use several times more water than the native vegetation they replaced. They are sustained mostly with imported water and we can easily use less.


The Facts -


Of the past eleven years, eight have produced below-normal rainfall, including the driest year on record. Our accumulated deficit of 21.75 inches (Lindberg Field) dried out native vegetation, fueling two major wildfires. Our water sources are 10% local, 55% from the Colorado River, and 35% from northern California. Reservoirs in eight western states have been severely depleted by drought that could last another decade. Court rulings to protect endangered fish could reduce northern California water up to 50% for years to come. A long-term decline in rainfall could further reduce our future supply.


If not now, when?


In 2008 the demand for water exceeded our county supply. The allocation to some farmers was cut 30%. Everyone was asked to reduce water use by 10% - but we achieved only 5%. In 2009 water districts are poised to implement mandatory conservation measures.

Changing decades-long habits requires a commitment, yet provides rewards. Conserving water will keep more “green” in your wallet. Local water districts will pass along 2008 wholesale cost increases of 11.9%. San Diego increased its water rate 6.5% and its sewer fee 8.75% in 2008. Similar increases will occur in 2009 and 2010. Expected increases in energy costs and measures to reduce carbon emissions will also increase water rates. Nineteen percent of California’s total power is used to transport and process water. Conservation will reduce both power and water use. Conversely, being able to afford as much water as you want is not a good reason to waste our precious resources.


If not you, who?


So, this is our challenge: to significantly cut landscape water use and minimize water expense!
