It’s the time of year of high water bills – and perhaps time to think about replacing plants that need too much water, or maybe even taking out some of your thirsty grass.
I recently came back from the Midwest where drought conditions have prompted many folks to let their lawns go dormant. When I came back I was struck by the irony of how we here in SoCA keep watering our grass during the many months of no rain while our friends in other places let theirs go dormant.
We’ve removed nearly all of our lawn (helped by the fact it was dead when we moved in four years ago.) I’ll share our method but wanted to share other ways. Rancho Santa Ana Botanic Garden (RSABG), a botanic garden in Claremont CA which features California native plants provided much of the info below:
Why remove lawn?
In addition to lower water bills and lawn care savings, other plants, especially California native plants offer better habitat value – numerous bees, butterflies, lizards, bees & other insects make our yard their home now. Also, check your city for lawn removal rebates.
Ways to remove lawn?
- Digging out the grass
- Cutting off the water supply (it’s good to let your neighbors know what you’re doing…)
- lasagna-method—laying cardboard sheets on the grass, covering it with mulch, wetting it down and allowing the whole thing to decompose over time.
- Herbicides or pre-emergents – However, I discourage this because they side effects and the above non-chemical methods work
According to Rancho Santa Ana Botanic Garden in Claremont, “the best method depends on the type of grass, whether it is in sun or shade and what will be planted in the new garden.: For example, Bermuda grass in the shade can be killed easier by taking the water supply off. In the sun Bermuda can survive on virtually nothing. If you expect to plant a groundcover, you will pay special care to removing weeds because they will be very difficult to control when you have to pick them out of the new plantings. However, the grass and other weeds will likely require some ongoing removal. Here is an article for more info.
Our lawn was already dead so we hired help to dig it out. We ended up having to pull up remnant grass for a couple years but it really wasn’t difficult, especially since the grass blades were obvious between our growing native and drought tolerant plants.
Keep in mind your existing trees,: Trees in your grassy areas are important and will need the water they are used to. For example, our magnolia tree needs more water than our new landscaping gives it, so our rain barrel system provides extra water in the rainy season, and we water it extra other times of the year.
What to replace it with?
Lawn or groundcover: Although California native plants do not behave quite like turf, there are several native plants that make nice, low groundcovers.
- A mix of blue grama grass (Bouteloua gracilis) and buffalograss (Buchloe dactyloides) makes a nice native turf (Western, not California native). Although some say buffalo grass grown from plugs does better, we did a mix of both, which did well. See article about our process here. According to Emily Neiman of Native American Seed, planting with enough seed will help prevent weeds that sometimes comes up with lighter seeding rates.
- Yarrow, (Achillea millefolium‘Rosea’) can also be used as a turf substitute (see Lummis House in Los Angeles) . Can be mowed. Is more for looks – will take some foot traffic but is not a play surface
- Clustered field sedge (Carex praegracilus) is another native turf substitute that has a dense, dark lawn look. It requires water, though probably less than traditional turf grasses. Leave it be and create a meadow garden. or you can mow it occasionally.
Hardscape/stones: Recycled concrete, flagstone, decomposed granite or other inorganic surfaces can also be used for a low maintenance garden area that will take foot traffic. These permeable surfaces reduce urban runoff that is responsible for much of our coastal pollution.
Native plants/drought-tolerant plants: This was our choice and we’re very happy with it. We planted a variety of plants (sages, ceanothus, manzanita, buckwheat plus others) See write-up http://www.ci.redlands.ca.us/utilities/water_conservation2.htm
To decide, figure out what you need for play areas and for pets. We kept a small area for our dog. Reduce your own lawn to the minimum to meet your needs, Make sure to reduce the water on that area as obviously you won’t save water if everything gets the amount of water required by turf, and many low-water use plants will fail in these conditions.
