MOW NO MORE

tip of the month – august 2012

By Cynthia Ruzzi, President

My family has always been grateful for the ‘dog day afternoons’ of August.  Sure to be filled with hot, sunny skies its’ time to leave lawn chores behind and head to the beach.  For years, we made sure to lighten our burden by following prudent grass growing techniques to make our escape easier and less guilt ridden.

Long ago we stopped using synthetic fertilizers because they are a threat to the bay as they wash down storm drains. Of the 30 commonly used lawn pesticides, 24 are toxic to fish and other aquatic organisms vital to our ecosystem and others are toxic to birds, bees and humans, htttp://beyondpesticides.org/lawn/factsheets/30health.pdf .   Additionally, these chemicals are formulated to stimulate a lot of grass growth quickly, demanding more water and even more mowing! Using organic products and grass clippings that work with the soil and feed the lawn slowly over the season makes for less work.  Every spring until after Labor Day, we’d set our lawnmower blade higher to leave our grass at least 3 inches long after each ‘haircut’. The taller grass shaded the surface of the soil preventing crabgrass and other weed seeds from taking root, helped conserve water and thus, encouraged deep root growth to allow our lawn to become more drought-tolerant.

When my youngest son shared EPA statistics learned in his high school AP Environmental Science class about gas powered lawnmowers representing 5% of the US air pollution before 1997, we had our excuse to look for alternatives.  Unregulated for emissions until the late 1990’s, gas powered garden equipment emit high levels of carbon monoxide, volatile organic compounds and nitrogen oxide – in other words pollution in your backyard. In fact, the EPA states that a new gas powered lawn mower produces enough air pollution in one hour as 11 new cars each being driven for one hour. http://www.epa.gov/air/community/details/yardequip_addl_info.html

The solution seemed apparent after a trip to the local hardware store where my husband ‘oohed’ over the latest ‘push’ mowers that definitely are not your father’s lawnmower.  Touting high-grade plastics, lightweight metals, precision blades that rarely need sharpening and promising the cutting of grass cleanly and evenly, we were almost there.   And then, the water emergency of 2009 hit us.  EBMUD penalized any resident that didn’t cut their water usage by twenty percent.  Given that we were already using an on-demand water heater, a high efficiency washer and dryer and a foot peddle that controls the water faucet in the kitchen sink to turn off the water when not needed, it was up to our garden to give up ‘it’s drink’.  This only made sense since more than 30 percent of all urban fresh water is used for watering lawns.  Imagine how much is wasted because of inappropriate timing, dosage or misdirected sprinklers.  I went outside and explained the situation to the grass and plants, “Look guys it’s been lovely, but you either flourish on once a week watering or be composted”.  More than half the garden made it, including my favorite rose bush, now entering its 32th year of precious yellow blooms.  However, I needed replacement for the other half of plants and the ‘California Golden’ lawn.  Luckily that’s when I came across an EBMUD program to convert my garden grass to a native plant landscape.

The EBMUD rebate program (extended to December 31, 2012) provides up to $500 dollars to help transform your lawn into water permeable and drought-resistant landscape.  Converting our front and back lawns through the EBMUD program was very simple.  The first step is to measure the lawn area you want to convert than complete the application form which can be found online at https://www.ebmud.com/for-customers/water-conservation-rebates-and-services/watersmart-residential-lawn-conversion.

The best time to start the physical work of the project is mid-to-late September since new plants will benefit from the approaching winter dominancy and rains.  However, August is the perfect time to start the design process by familiarizing yourself with drought tolerant plants that will thrive in your microclimate.  A wonderful resource is EBMUD publication Plant and Landscapes for Summer-Dry Climates of the San Francisco Bay Region.  EBMUD also has a resource list of bay area nurseries, demonstration gardens, classes and books where you can learn about and view native plants.

As part of the lawn conversion program, an EBMUD representative will meet with you both pre and post-conversion.  The representative shared great resources and explained that using the process of sheet mulching would spare us the hard work of tearing out the lawn.  Sheet mulching is a layered mulching system that suppresses weeds and in the case of a lawn conversion, grass.  This process also made it possible to plant over 60 small plants in the front yard in one afternoon – alone.
