A short drive around Chico will reveal that lawn is a prominent landscape feature for the majority of homes. Yet we seldom see people outside using their front lawns. Maintaining a lawn just to view wastes time, energy, water and money. According to a 2011 study sponsored by the California Department of Water Resources (“California Single Family Water Use Efficiency Study”), the average household uses 360 gallons of water per day, around 50% of it outdoors. Replacing lawn with waterwise landscaping can reduce outdoor water use by 30-70%. In addition, lawns need mowing, fertilizing and weeding.
Start with hardscaping: walkways, gravel paths, small patios or decks, dry creek beds and retaining walls. These provide visual interest and reduce irrigated areas. Plan a pleasing and obvious walkway to your front door. You can edge it with intervals of plantings, in the ground or in urns. Meandering gravel paths provide a functional and low-cost way to move about the garden. A small patio invites you to relax. Dry creek beds and small retaining walls separate planting areas and provide elevation changes. You can also use an edging of stone or brick to separate planting areas.
The New Sunset Western Garden Book and Calscape (California Native Plant Society's database of native plants) provide information about waterwise plants. If your yard will include automatic irrigation, group together plants with similar water needs.
The UC Cooperative Extension WUCOLS database estimates the water needs of thousands of garden plants and is a valuable tool for grouping plants into hydrozones.
Consider adding focal points. A water feature attracts birds to the garden. It can be as elaborate as a fountain or as simple as a ceramic dish. Large boulders also provide visual interest. A bench flanked by large pots of colorful flowering plants invites you to sit and enjoy your garden.
Visit the Master Gardener Demonstration Garden at Patrick Ranch (10381 Midway in Durham) to see a variety of gardens that are waterwise, interesting and beautiful without relying on areas of lawn. Our gardens are free to visit and are open whenever Patrick Ranch is open to the public.
We have endured multiple years of drought, and are probably in store for more. For many of us, it makes sense to replace all or part of our lawn area with less water-intensive plantings.
Step One: observe and plan. What existing trees and plants do you want to keep or remove? What are the sun and shade patterns within your yard? What types of grass grow in your lawn? Do you want any additional amenities, such as paving or a shade structure? How will you irrigate your new plants?
Step Two: kill your lawn. Homeowners can use two eco-friendly methods to kill their lawns: Solarizing or Sheet Mulching. For detailed instructions on solarizing, click here. For instructions on sheet mulching, click here.
Sheet mulching kills weeds by starving them of light. It takes 6 to 10 months and can be started any time of the year as long as at least three months of growing season are included. Sheet mulching works in sun or shade, and is effective on all grasses, including Bermuda grass, and many annual and perennial weeds. It is left in place permanently; over time, the dead lawn, sheeting, and mulch will break down into soil-enriching compost. Sheet mulching should be placed before new plants are installed if being used alone to kill lawn or weeds. It can be placed after plants are installed if solarizing has been completed first. New hardscape and irrigation should be installed before commencing solarizing or sheet mulching.
Step Three: replant. Whichever method you choose to kill your lawn, time it so that you are ready to replant in the fall, winter, or early spring. The cool temperatures and moist soils of our wet season allow drought tolerant plants to develop the healthy roots they need to thrive with little water during the heat of summer. Taking time to thoroughly kill the grass and waiting until the climate conditions are suitable for new plants will ensure the long-term success of a lawn replacement project.

Does growing a vegetable garden sound like something you'd like to do, but you don't feel equipped? So, here's the deal. Find some dirt, and then plant. It's that simple. If you want to grow food, the first step is to find some dirt. Consider the usable ground you have. Take a look around. Maybe it's that patch of front lawn that you're tired of mowing, or haven't mowed at all. Could it be the bare spot in the back where the dog likes to poop? Step One is to find some dirt, and don't be judgy about the dirt you have. Your dirt is full of potential.
Your objective is to give your dirt some tender loving care, and your soil will return the favor by giving you healthier plants and better produce. Your soil's mineral composition is what it is, but one element we can be altered is organic material. No matter what kind of dirt you have, adding organic matter will make it better. Organic materials include grass clippings, fallen leaves, straw, wood chips and bark, hulls, plant clippings (chopped small) and everyone's favorite...manure. Now, here's an important point: it takes time for the organic materials to break down and start to enrich the soil, to become usable to plants. So, what's the best and quickest way to get those things into your soil? Compost. Compost is already mostly decomposed organic matter, so it mixes into the soil and continues to decompose slowly, releasing nutrients to plants and improving soil texture. Compost costs money, but you can also make your own in as little as 2 to 3 weeks at little or no cost. This article has a complete description of DIY compost: Compost in a Hurry (UC ANR Publication 8037).
Think of mulching as another method of composting that involves placing a thick layer of organic matter on top of the soil and letting it decompose very slowly. It's even better to put a layer of newspaper or cardboard on the ground first, wet it, and then spread out the organic material on top, about 4 inches thick. The organic matter and the paper or cardboard underneath will break down over the next 6 to 10 months. To add plants, push aside the mulch, expose the paper or cardboard, and cut an "X" large enough to accommodate your plant. Fold back the flaps, dig a hole, and add your plant. When done, lay the flaps back in place and re-cover with mulch. Remember that front lawn that you're thinking could be a vegetable garden? This method of sheet mulching is one way you get rid of the grass! Cover it, mulch it, forget about it. If you want to learn more about lawn removal, here's an article containing complete instructions: Lawn Removal: Do It Right.

A short drive around Chico's various neighborhoods will convince you that people love their front lawns. They must, because the lawn is the most prominent landscape feature for the vast majority of homes. And yet, we seldom see people outside actually using their front lawn spaces. Maintaining a lawn just to view through your front picture window wastes time, energy, water and money. According to a 2011 study sponsored by the California Department of Water Resources (the “California Single Family Water Use Efficiency Study”), the average household in the state uses 360 gallons of water per day, around 50% of which is used outdoors. Replacing the lawn with waterwise landscaping can reduce outdoor water use by 30-70%. In addition, lawns need to be frequently mowed, fertilized and weeded, thus racking up additional costs. So replacing or significantly reducing lawn can result in considerable savings.
Start your design with hardscaping. Hardscaping can include walkways, gravel paths, small patios or decks, dry creek beds and retaining walls. These provide visual interest and also reduce the area that needs to be irrigated. Plan a pleasing and obvious way to get to your front door. You can edge the walkway with plantings in the ground or in urns at intervals along the way. Meandering gravel paths provide a functional and low cost way to move about the garden to observe plantings more closely. A small patio allows you to relax and enjoy a cup of tea in the yard. Dry creek beds and small retaining walls are features that separate planting areas and provide elevation changes in the yard. You can also use an edging of stone or brick to separate planting areas.
The New Sunset Western Garden Book and Calscape (the California Native Plant Society's online database of native plants) are good sources of horticultural information about waterwise plants. If your yard will be irrigated with an automatic system, it makes sense to group together plants with similar water needs. The UC Cooperative Extension WUCOLS database allows you to estimate the water needs of thousands of garden plants grown in the Chico area. This database is a valuable tool for grouping plants into zones based on their water needs.
Mulching the bare spots will help to conserve moisture by reducing evaporation and controlling weeds. You can use organic mulch (like shredded bark) or inorganic mulch (like gravel or small rocks). Keep organic mulch a few inches away from the trunks of trees and plants. Excessive moisture that is trapped by mulch too close to the trunk can lead to fungal diseases in the plant. Inorganic mulch can itself become a design element, for example by using different sizes or colors of rocks in different areas.

California Water Service is currently offering rebates of up to $1000 for lawn removal and replacement with drought-tolerant plants in single-family residences. It's not difficult to realize landscape water savings of over 80% through careful plant selection and site preparation, and accurate application of irrigation according to the plants' actual needs.
If you plan to undertake a lawn replacement, make sure you do it properly; incompletely killed grass can regrow amid new plantings, ruining the appearance of your new landscape and creating a maintenance nightmare. The following three steps will lead to success.
Step One: observe and plan. What existing trees and plants do you want to keep or remove? What are the sun and shade patterns within your yard? What types of grass grow in your lawn? Do you want any additional amenities, such as paving or a shade structure? How will you irrigate your new plants?
Step Two: kill your lawn. Homeowners can use two eco-friendly methods to kill their lawns: Solarizing or Sheet Mulching (also below).
Solarizing uses the sun's radiation to kill lawn grasses as well as many common annual weeds, harmful soil microbes, and seeds down to a depth of 4 to 12 inches in six weeks. Most beneficial microbes survive, including earthworms. Solarizing requires six hours per day of full summer sun and takes 4 to 6 weeks to complete. It works best on fescue, ryegrass, and bluegrass, with partial success on Bermuda grass. Solarizing must be completed before new plants are installed.
Sheet mulching kills weeds by starving them of light. It takes 6 to 10 months and can be started any time of the year as long as at least three months of growing season are included. Sheet mulching works in sun or shade, and is effective on all grasses, including Bermuda grass, and many annual and perennial weeds. It is left in place permanently; over time, the dead lawn, sheeting, and mulch will break down into soil-enriching compost. Sheet mulching should be placed before new plants are installed if being used alone to kill lawn or weeds. It can be placed after plants are installed if solarizing has been completed first. New hardscape and irrigation should be installed before commencing solarizing or sheet mulching.
A third option for lawn removal is to dig or scrape out the lawn. Be warned, however, that this method will not kill Bermuda grass and most perennial weeds, which have deep roots that will re-sprout. If you choose to dig out your Bermuda grass lawn, be sure to follow up with sheet mulching to prevent aggressive regrowth of the grass.
Step Three: replant. Whichever method you choose to kill your lawn, time implementation so that you are ready to replant in the fall, winter, or early spring. The cool temperatures and moist soils of our wet season allow drought tolerant plants to develop the healthy roots they need to thrive with little water during the heat of summer. Taking time to thoroughly kill the grass and waiting until the climate conditions are suitable for new plants will ensure the long-term success of a lawn replacement project.

Sheet Mulching, By Eve Werner, Butte County Master Gardener
Sheet mulching, also known as sheet composting, kills weeds by starving them of light. Dead plant material will break down into compost to enrich the soil. New weeds are reduced because it is difficult for them to anchor their roots in deep mulch. The sheeting and the mulch will break down over time, forming compost. Sheet mulching should be placed before new plants are installed if being used to kill lawn or weeds. It can be placed after plants are installed if other weed removal techniques such as solarizing have been completed first.
Materials:
- Newspaper or plain cardboard. Don't use glossy colored pages as they may contain metal pigments.
- Water from a hose with a spray attachment.
- Compost or worm castings in a 1-2” layer. Quantity calculation for mulch is: (Area in square feet) x .08 to .15 ÷ 27 = cubic yards of compost required. Note, if you are replanting with native CA plants, you can omit this step.
- Wood chip mulch in a 4”-6” layer. ‘Walk-on' bark, has longish strips of wood and barks that knit together to help it stay in place. Shredded wood/barkmayalsobeavailablethrougharborists for much less cost; verify with the supplier that it is disease free.
- Quantity calculation for mulch is: (Area in square feet x .33 to .5) ÷ 27 = cubic yards of mulch required.
Process
- Scalp your lawn or weedy area with mower set at lowest setting. Remove grass/weed clippings.
- Water the soil thoroughly. To prevent runoff, you may have to apply water for a short period, wait for it to soak in, and then repeat as needed.
- To reduce spillage of mulch onto adjacent paving, dig a shallow beveled trench along any edges that are bordered by paving. See drawing, below.
- Spread 1-2” depth of compost or worm castings over entire area.
- On a windless day, place newspaper (about 5-8 sheets thickness) or cardboard over grass to be killed, overlapping like shingles. Make sure there or no gaps or holes. Lightly sprinkle newspaper with water as you go to prevent it from blowing away. Once wet, the paper will easily tear; be careful when walking on it. If it tears, place additional newspaper over the hole.
- If you are laying the sheeting around existing plants, keep the paper a foot from the plant stem, further for plants that spread by underground stems.
- As you are laying the paper, place wood mulch over the top of the paper to a 4”-6” depth. Place the mulch as you lay the paper so you don't have to walk on/tear the wet paper. If you are placing the mulch when the plants are already in the ground, keep the mulch a foot from the plant stem.
- Sheet mulching requires 6-10 months to kill a lawn. It can be left in place permanently.
- To plant with sheet mulching in place, push back the mulch and cut away paper sheeting in a circle wide enough to dig your hole. Dig the planting hole 2x the width and 1x the depth of the plant root ball. Loosen coiled roots and place the plant in the soil so that the top of the root ball is slightly above the adjacent soil. Back fill with soil from hole, forming a slight rim at the edge of the planting hole. Replace mulch, keeping it 8” from the plant stems.
Sheet Mulching in Progress
Beveled trench along the sidewalk, newspaper layered 5-8 sheets thick, and an initial layer of wood chip mulch.
