Lawn Substitutes…..

April  7, 2015

The whole great State of California has a mandate to reduce water use by 25%.  Although it is going to be diffuclt, we can easily achieve this–stop watering our lawns.   This will be a massive savings of water since about 9 out of 10 homeowners have lawn.

The design aspect of having a lawn, may seem simple, but that is because it is over used.   The real issue is complex.  First of all, lawns are a necesary evil, especially if you have children, pets or enjoy outdoor activities.  There is nothing like grass to take foot traffic.  So, not all lawns are objectable.   The issue is how we have all used grass as a ground cover, millions and millions of  Californians.   I say, if the only person who walks on your lawn is the gardener, then let that lawn go!  A lawn should be no more than 30% of your total gardening space.  As we are in a dought I would reduce that number by half.  We must sacrifice, there is no choice.  I also object to municipal medians and parkways that use grass as a ground cover.  Again, if the only person who walks on it is the gardener—-let it go!

At Indah Bulan, we tend to always remove lawns except where useful .  Here are some alternatives to having a lawn or lawn substitutes.

  1. Red Fescue (Festuca rubrum) This is a California native grass that grows well with little water.
  2. Mulch…. until you can figure out what to do, simply much the dead lawn.
  3. For areas to be used for entertaining, use pavers set in gravel.  This will allow the water to percolate back into the ground, create a pattern and most importantly define an area with style.
  4. Succulents, these can be planted year round and enjoy being dry.  Most tend to be more colorful with dry heat.
  5. Plant a Grove of Trees… fill your old lawn area with trees, turn it into a woodland.
  6. Create a path and planting areas.   This creates a garden that has visual interest and practicality if the paths are well thought out.
  7. Evergreen Ground Covers.  There are hundreds of choices.  If you want a look to replicate grass, choose a plant with small leaves.  A really good choice is Achillea milliafolium.  It is a low growning yarrow, that can take some foot traffic, being mowed, and has a flower.
  8. Create a riparian area with native rocks, trees, shrubs and design.
  9. Create a planting design that uses mass plantings of a single variety of low shrub(s).
  10. Do nothing until you have a plan.  Mow the grass down as low to the ground as possble, stop watering and take time to dream.  Use the drought to solve a problem thoughtfully.

There really are so many wonderful options.  When we design a garden for clients, we choose what is best for them, the architecture of their home and how they want to use it.  This is a great opportunity to create something that is special, practical, sustainable and gorgeous.

Water Conservation …. Lawns

As a landscape architect, I see potential everywhere!  Many times that comes from identifying the problem first. We are experiencing a major drought in California.  The biggest problem I see are all those unused grassy areas in front of most homes.  I want my first blog to be about those lawns and grassy areas that could still be green, just in a different more sustainable way.

Having a lawn is not bad or improper in and of itself.  But, in an arid climate using a lawn as a default planting for 95% of a front landscape requires a staggering amount of water and weekly maintenance. Another waste is seeing grass in a municipal median that is only walked on as it is mowed.   There is nothing like grass for areas that are to be used by families for outdoor activities since, if healthy, can take heavy use. What I want to address is a grassy lawn that is just a visual.

Here are a few suggestions to make your lawn more sustainable.

  •  If the only people who walk on your lawn are the “gardeners”….. let it go. Place a thick layer of mulch until you figure out how the area is to be used.  Stop watering the area.
  • If you use the lawn occasionally for activities or parties, make sure you have a grass that is appropriate for your climate.  For instance, St. Augustine Turf is a tropical grass.  It requires much more water than a typical fescue.   Overseed your lawn with a mixture of drought tolerant seeds.
  • If you have a grassy area that will be kept, then trim it to the proper height.  Ask your gardener to raise his lawn mower blade to 3″, 4″ is better.   This simple task will help your lawn to retain more water.  The longer blades will provide shade for the roots. It will also look more healthy.  It takes more water to regrow from being scalped than it does to maintain a longer blade.  Of course the big problem with this is most gardeners seem to only speak Spanish.  Here is a printable statement you can simply hand to your gardener.  …..Maybe give him an extra $5 tip.

In English:

To help conserve water, please raise mower blade to 3″.  Thank you!

In Spanish: 

Para ayudar a conservar el agua, por favor, levanten la cuchilla de corte a 3 pulgadas. Gracias!  


  • Water less for longer.  Instead of watering 3 times a week, water every two weeks for 20-30 minutes…. or better yet wait until your grass looks like it needs water.  You will be amazed that having the grass trimmed at a constant 3″ requires less water.  …….Water only when necessary.
  •   If water is running over the sidewalk, there are issues with the water percolating into the ground…. If grass is what you want, this may be the perfect time to aerate or till and add organic material to the soil so it can retain the precious moisture it receives.
  • Make sure the irrigation system is fine-tuned to eliminate over spray.  Water early in the morning (remember water fewer times).
  • Plant a tree or a grove of trees to reduce all that hot sun on your house and as the trees grow seed a shady grass mix.
  • Replace the lawn with a ground cover (lawn substitute).

Next time……lawn substitutes
