A sustainable landscape needs less water and is more tolerant of heat and drought than a traditional lawn and landscape. It also needs less maintenance than a lawn.
Water Saving Ideas
The best approach to a sustainable landscape is to think gardening, not yardwork, and to think of your garden as an extension of your living space — because here in San Diego you can enjoy an indoor-outdoor lifestyle year-round. Jot down a wish list of what you would like to have in your garden and you might just find that you no longer have room for a big lawn.
Citrus and avocado trees, most vegetables, and Mediterranean and California native plants all use less water than cool season turf. And your new front porch and backyard dining area won’t need any water.
Create a place to drink coffee in the morning and have friends over in the evening — under or next to a shade tree. You don’t need a deck, just gravel, or make some concrete pavers.
Grow organic vegetables in raised garden beds, have your own little orchard and grow a kiwi vine on the back fence.
Save the Bees
Plants native to California are home, sweet home for bees. Bee populations are dwindling and they need new habitat.
Meet Your Neighbors
Create a front porch where you can sit and read the mail and you’ll end up making new friends. Gravel or bark and a couple of chairs is all you need.
Reduce Water Pollution
Create a 3-foot wide, 6-inch high berm with plants between lawn and hardscape to prevent runoff from rain and sprinklers.
Shade trees make a garden comfortable, raise property values and reduce irrigation costs.
Sustainable and Beautiful
There is endless variety of plants that thrive in San Diego’s Mediterranean climate with less water than a lawn needs. We describe how much water these plants use as a percentage of how much water a healthy lawn of cool season turf uses, and group them in three categories: moderate water use, low water use and very low water use.
High Water Use
These plants use as much water as cool season turf
Moderate Water Use
These plants use 50% of the water cool season turf uses
Low Water Use
These plants use 30% of the water cool season turf uses
Very Low Water Use
These plants use 10% of the water cool season turf uses
Moderate Water Use Plants
You can reduce your water use by 30 percent wherever you replace cool season turf with moderate water use plants. These are just a few of the hundreds of plants available.
Low Water Use Plants
You can reduce your water use by 50 percent wherever you replace cool season turf with moderate water use plants. There are many more to choose from than what we have here.
Very Low Water Use Plants
You can reduce your water use by 70 percent wherever you replace cool season turf with moderate water use plants, and these are just a few of the plants in this category.
The Key to Saving Water
The key to saving water is to group plants together in your landscape based on how much water they use.
When you irrigate high, medium and low water use plants with the same sprinkler, you overwater or underwater or both. When you group plants together that need the same amount of water, you can give them just the right amount — and that’s efficient. Each group of plants is called a hydrozone.
How to Create Hydrozones
After you create the layout of your new landscape design, decide where plants will go, and select plants that need the same amount of water for each location. If you want to keep your current irrigation system, transform each of your irrigation zones into a hydrozone.
It’s a Big Project, With Big Rewards
A smaller water bill might be the incentive that gets you started, but less maintenance and no more mowing and blowing feels really good, too. And there’s a good chance that talking with neighbors on the front porch will become a new favorite thing.
