"This past February 2020 was the first time since 1864 - when the Civil War was raging and covered wagons roamed the American West - that San Francisco had no measurable rain in February, normally one of the wettest months of the year." (Source)
With 25% of the state already declared to be in a drought, it's time to think about reducing water consumption at your home! Water is too precious to spend keeping your thirsty lawn green.
Learn to convert your thirsty lawn to a beautiful water-smart garden!
Join us on Saturday, March 14 for our hands-on "Replace Your Lawn with a Water-Smart Garden" workshop at the beautiful Pittsburg Living Green Garden. We will teach you the low-cost, SIMPLE method of lawn conversion, without digging up your old lawn! Garden designer Kelly Marshall will teach you how to create a site analysis of your space, choose plants to create a picturesque drought-tolerant garden, and guide you through the step-by-step process of lawn conversion.
Additionally, you will learn techniques to keep your new garden happy and healthy, such as frost protection. We will also discuss creating your own year-round garden maintenance plan.

Want a little sneak-peak?
A Sustainable Contra Costa board member converted her lawn through sheet-mulching. Not familiar with that term? It's a layered mulch system that nurtures the soil and replaces existing lawns or weeds, eliminating the need to remove unwanted plant material (no harsh herbicides, no roto-tilling!).
1. Apply for a lawn conversion rebate BEFORE you start,
if you are removing a lawn and planning to replace it with drought-tolerant landscaping (such as low-water or native plants). The water district will come out to measure your lawn and confirm that you qualitfy. You may want to check if you qualify for both your local rebate and the State Rebate
; you could potentially get up to $2 per square foot that you convert! Then, stop watering your lawn and let it die. Before your sheet-mulching weekend, water the ground thoroughly.
3. Dig a trench around all edges of your lawn, including edges butting up against your driveway or other hardscapes. Dig at least 2 inches deep and up to a foot wide - this will create a low point along the pavement so the mulch will not spill out. You can put the dirt you dig up onto the other parts of your lawn, to incorporate the nutrients back into the earth.
2. Find and cap all of your sprinklers. Dig around each sprinkler head, going 3 - 5 inches deep until you are below the connection point. Unscrew the sprinkler head and screw on a cap - I used simple PVC caps from the hardware store. Some sprinkler heads required a special tool to remove pieces if they broke and got stuck. You may want to also put a flag by each sprinkler head so you can find it again after you mulch (ex. if you are converting to a drip irrigation system).
4. Apply a thin layer of compost (~1 inch) over the dead lawn or weeded area. You can order compost and mulch from many local facilities, and most offer delivery services.
5. Layer flat sheets of cardboard over the area, making sure to overlap the sheets by 2 inches to make sure no light can penetrate through to the grass or weeds below. I used large cardboard boxes from friends who had just moved, as well as flat pieces of cardboard I got from Costco (make sure you ask first!). Remove any tape that may be on the boxes (tape won't decompose). Helpful hint - you will need more cardboard than you think. I made 2 additional trips to get more cardboard even after I thought I had enough!
6. Water the cardboard. Wave to your neighbors as they pass by, wondering if you've gone crazy.
7. Spread ~3 inches of mulch on top of the wet cardboard.
8. Sit back, relax, and let the sheet mulch "cook" for a month (or more) before planting! This will allow everything to settle, and the cardboard (which acts as a weed-blocker) and dead grass/weeds will slowly decompose into the ground. If you plan soon after, you'll just need to cut holes in the cardboard where your plants will go in.
This particular front yard conversion project will be incorporating some pollinator-friendly and drougt-tolerant plants as well as two trees. Check if your water agency provides a landscape design assistance program so you can utilize a professional designer to help transform your yard from water-thirsty and boring, to drought-tolerant and beautiful.
