How to Replace Your Lawn with California Native Plants

Replacing lawn with appropriately sited California native plants can substantially reduce irrigation and add habitat, but savings vary with the former turf, site, plant choices, and irrigation. The California Native Plant Society reports an average 83% reduction in water use for native plant gardens. Soquel Creek Water District currently offers qualifying customers up to $2 per square foot for turf replacement; review the current application before removing turf.

Why Replace Your Lawn with Natives?

A conventional lawn is the single thirstiest, highest-maintenance feature in most yards, and it gives very little back. In California, where summer rain essentially does not fall for months, keeping turf green means running sprinklers constantly through the dry season.

The water reduction can be significant, but a fixed gallons-per-square-foot estimate is not reliable for every Santa Cruz property. CNPS reports an average 83% reduction for native plant gardens; actual savings depend on prior lawn irrigation, climate, soil, plant selection, establishment needs, and the new irrigation schedule.

Beyond water, a native planting eliminates mowing, needs no fertilizer or chemical weed-and-feed, and turns a sterile green rectangle into habitat. According to the California Native Plant Society, native plants support the local bees, butterflies, and birds that lawns cannot, and they are adapted to our climate, so they thrive on rainfall alone once established.

There is a trade-off worth naming: a native garden is not a play surface the way a lawn is. If you have children or dogs who need open turf, consider converting only part of the lawn and keeping a smaller play area, or using a tough native like yarrow or a sedge as a low-traffic lawn alternative.

How Much Water and Money Can You Actually Save?

The savings depend on lawn size, but the numbers add up quickly and they are worth calculating before you start.

Water saved. Avoid projecting a universal gallons-per-square-foot total. CNPS reports an average 83% water-use reduction for native plant gardens, but your result will depend on prior turf watering and how the replacement landscape is designed and irrigated.

Rebate money. Soquel Creek Water District currently lists up to $2 per square foot for qualifying turf replacement, with a $2,000 per fiscal-year maximum for single-family residential customers. Funding, eligibility, and application requirements can change, so apply through the district and receive any required approval before removing turf.

Ongoing savings. Beyond the one-time rebate, you save every month on the water bill, plus the cost and time of mowing, fertilizer, and lawn care for years to come.

Even without a rebate, replacing some turf may reduce irrigation and maintenance, but the financial payback depends on project cost, prior water use, and ongoing care. Compare those factors for your own site instead of assuming a fixed payback period.

How Do You Remove a Lawn Without a Lot of Digging?

You do not need to rent a sod cutter or dig out the whole lawn, though you can. For most homeowners, the easiest and most soil-friendly method is sheet mulching, which smothers the grass in place.

Sheet mulching (the recommended method). Mow the lawn low, then lay overlapping sheets of plain cardboard (tape and labels removed) directly over the grass, overlapping the edges by six inches or more so no light gets through. Wet the cardboard thoroughly, then cover it with four to six inches of mulch or compost. The grass dies from lack of light, and over several months the cardboard and grass break down into the soil, feeding it. According to sustainable landscaping guidance, this method suppresses the lawn while improving the soil and requires no chemicals and little digging.

Timing. Start sheet mulching in late summer or early fall so the lawn smothers over the wet season and beds are ready for fall or winter native planting. In Santa Cruz County, a sheet mulch laid in September is usually ready to plant into by late fall.

Other methods. Solarization (covering the lawn with clear plastic to bake it in the sun) works in the hottest inland areas but is unreliable in the foggy coastal belt where summer heat is limited. Manual sod removal or a sod cutter is faster but harder work and strips off valuable topsoil. We compare all of these in detail in our guide to converting lawn to garden in Santa Cruz County.

One tip: for aggressive lawns like Bermuda grass, sheet mulching alone may not fully kill it, and you may need a thicker cardboard layer, a longer smothering period, or spot removal of survivors.

What Native Plants Should You Use to Replace a Lawn?

The best replacement depends on whether you want a low, walkable green surface that reads like a lawn, or a fuller mixed planting of shrubs and perennials. Most successful conversions use a mix.

For a lawn-like green surface:

• Native yarrow (Achillea millefolium) forms a low, soft, mowable mat that tolerates light foot traffic and needs little water.
• Native sedges (Carex pansa, Carex tumulicola) create a fine-textured green groundcover that can be left shaggy or mown a few times a year for a meadow look.
• Beach strawberry (Fragaria chiloensis) spreads into a glossy green mat and handles coastal fog well.

For a mixed native planting:

• Groundcover manzanita and ceanothus (such as 'Emerald Carpet' manzanita or a prostrate ceanothus) cover ground with evergreen foliage and seasonal flowers while suppressing weeds.
• California fuchsia, sticky monkeyflower, and buckwheat add color and feed hummingbirds and pollinators.
• Deer grass and other bunchgrasses give structure and movement.

We round up the best low options in our guide to native groundcovers for Santa Cruz gardens, and because a lawn conversion is also a chance to improve fire safety, see groundcovers that replace lawn and reduce fire risk. For choosing between a living groundcover and plain mulch in different areas, our comparison of mulch versus ground cover plants for weed control is useful.

Aim to space plants so they will grow together and cover the soil within a couple of years, which shades out weeds and reduces the mulch you need long term.

How Do You Design and Plant the New Native Garden?

A little planning turns a bare mulched area into a garden that looks intentional and thrives.

Plan for water zones. Group plants with similar water needs together (hydrozoning) so you can water the establishment-phase plants without overwatering drought-lovers. Our guide to native garden design in Santa Cruz County covers layout, layering, and plant combinations.

Match plants to your microclimate. Sunny, dry front yards suit Cleveland sage, buckwheat, California fuchsia, and manzanita; shadier or foggier spots favor Douglas iris, sedges, coffeeberry, and monkeyflower.

Convert irrigation to drip. Replace lawn spray heads with low-volume drip, which delivers water to plant roots efficiently and is usually required to qualify for a rebate. Drip lets you water deeply and infrequently, exactly what natives want.

Plant in fall. According to the California Native Plant Society, fall through early winter is the ideal planting window, so roots establish over the rainy season before the first dry summer. This is why the whole sheet-mulch-then-plant timeline is built around getting plants in the ground before winter rains.

Mulch the open areas. Cover any bare soil between plants with a few inches of coarse mulch to suppress weeds and hold moisture while plants fill in.

What Should You Expect the First Two Years?

Setting expectations honestly is the difference between a conversion that sticks and one that gets ripped out in frustration.

Year one looks sparse. Newly planted natives are small, and the garden will look thin with a lot of visible mulch. This is normal. Native plants put energy into roots first and top growth later. Resist the urge to overplant to fill the gaps, which leads to overcrowding as they mature.

Water during establishment. Newly planted natives still need careful irrigation. CNPS recommends keeping the root ball moist but not soggy during the first months, then watering less frequently and more deeply as the plant establishes. Follow species- and site-specific guidance rather than one schedule for every native.

Weeds will try to return. The disturbed, freshly mulched soil invites weeds. Pull them while small during the first year or two, and once your groundcovers knit together they will crowd most out.

Reduce water as plants establish. CNPS says many properly sited plants may be fairly established after the first year and can then receive much less irrigation. Establishment time and mature appearance vary by species, container size, site, weather, and care, so avoid promising one two-to-three-year outcome.

A lawn conversion is a project measured in seasons, not weekends, but few garden changes pay back as much in saved water, saved money, and added life. Start with a manageable section if the whole lawn feels daunting.

Frequently Asked Questions

How much water does replacing a lawn with natives save?

Replacing turf with a well-designed native garden can reduce irrigation substantially. CNPS reports an average 83% reduction for native plant gardens, but actual savings depend on the prior lawn, the site, plant choices, and irrigation management; do not use one gallons-per-square-foot estimate for every property.

Is there a rebate for removing my lawn in Santa Cruz County?

Yes, for qualifying district customers. Soquel Creek Water District currently lists up to $2 per square foot and a $2,000 per fiscal-year single-family maximum for turf replacement. Review the current application, eligibility, funding, and approval steps before removing turf.

What is the easiest way to remove a lawn?

Sheet mulching is the easiest, most soil-friendly method. Mow the grass low, cover it with overlapping wet cardboard, then add four to six inches of mulch or compost. The grass dies from lack of light and breaks down into the soil over several months, with no digging or chemicals required. Start in late summer or early fall so the lawn smothers over the wet season and beds are ready for fall native planting.

When should I plant natives after removing my lawn?

Plant in late fall through winter, once the rains have started, according to the California Native Plant Society. Fall planting lets roots establish through the cool, rainy season before the first dry summer, so plants need far less supplemental water. This is why the typical lawn conversion is timed to sheet-mulch in late summer, let the lawn smother over fall, and plant into the prepared beds as the winter rains begin.

Do native plants make a good lawn substitute for walking on?

Some do, but no native matches turf for heavy play or sports use. For a low, walkable green surface, native yarrow tolerates light foot traffic, and native sedges like Carex pansa form a soft, mowable meadow. For areas that need durable open space for children or dogs, consider keeping a smaller lawn or play area and converting the rest, since most native plantings are meant to be viewed and enjoyed rather than walked across regularly.

How long until a native garden looks established?

Native gardens often fill in gradually, but there is no universal year-one-to-year-three appearance schedule. CNPS advises careful establishment watering followed by progressively less irrigation as properly sited plants mature. Growth rate and summer-water needs vary by species, site, weather, and care.
