Tip of the Month – September 2015
By Cynthia Ruzzi, President Sustainable Danville
The California Department of Water Resources has announced new rebates to help replace old, inefficient toilets and lawns with water-saving alternatives.Besides the $100 rebate to replace one toilet per household, the bigger rebate is $2 per square foot for lawn replacement, up to $2,000 per household. www.SaveOurWaterRebates.com.
Now is an opportune time to replace your water-thirsty lawn because if the weather forecasts are right, we should soon receive El Nino soaking rains. My husband and I converted our front and backyard lawns in response to the 2008-09 EBMUD emergency requesting a 20% reduction in water use by residential customers. We stopped watering our lawns¾and plants¾with the idea that anything that couldn’t make it on once a month watering would be replaced.
There are many classes and free resources about drought tolerant plants including seasonal sales from The Garden at Heather Farm in Walnut Creek and the Horticulture Program at Diablo Valley College. I worked with Chris Finch, a drought tolerant plant expert that helped write the publication, Plants and Landscapes for Summer-Dry climates of the San Francisco Bay Region to identify plants that appealed to me and would work in our community’s climate. EBMUD also has a resource list of local nurseries, demonstration gardens, classes and events, and books where you can learn about and view native plants. Additionally, some local nurseries will design a lawn conversion planting plan for a fee and then rebate the fee as credit toward plants purchased.

After laying a new path of Kentucky Blue Stone pavers, we tapped off our sprinklers that would later be converted to drip irrigation. During the month, our neighbors and friends saved newspapers and cardboard to use for sheet mulching. This is an important step
in the conversion process because the sheet mulch kills the lawn and suppresses further weed growth while improving soil nutrients and structure and encouraging favorable microbial activity. Sheet mulching is a wonderful labor saver because it spares you the hard work of actually tearing out the lawn. However, if your lawn is full of tree roots you may have to do some additional digging or rototilling to rid the area of roots before you can lay down an effective mulch covering.

Once we had our plant layout, we knew exactly where we needed water, so we converted our sprinklers to drip irrigation. This weekend project was accomplished with a trip to the local hardware store that offers a screw-on octopus replacement to sprinkler heads that make it easy to connect tubing and drippers.
Once the sheet mulching was done, we covered it with 5 inches of compost. I was able to plant over 60 plants in one afternoon and because I used 4-inch sized pots and there was no need to dig into the cardboard/newspaper. While I was doubtful the plants would fill our yard, Chris assured me that they would be full-sized by spring. But she was right. I encourage you to visit lawn conversion page to see more pictures and learn more about the process.
