Here's an article that appeared October 4 in the Ventura County Star. Good information on drought-tolerant landscaping.

"Mow, blow and go" is still the
order of business for most lawn-maintenance companies, but as more grass is
being replaced with drought-tolerant plants, the landscape and the tasks needed
to maintain them are changing.
Shrubs need pruning and ever-present
weeds need pulling. More of these types of duties could actually increase the
time a gardener is on site, while new designs that effectively catch rainwater
runoff could reduce the need for sprinkler irrigation.
"Re-educating homeowners and landscape
companies about bioswales, rain gardens and gray-water irrigation is what we
are trying to do," said Laura Maher, 40, co-founder of Eco Restoration Partners
in Camarillo. "We take a watershed-wise approach to the topography and grading
of the house. Normally homes are graded to push the water away, so the water
doesn't damage the home. However the concept of slowing, sinking and spreading
of rain water is what we are trying to achieve, so you don't need outside
irrigation if you design and plant right."

It's not exclusively about planting
cactus, a living symbol of drought tolerance. Shrubs such as devil's trumpet
(botanical name: datura) and Brazilian sky flower (botanical name: duranta) are
popular and drought tolerant.
"People think drought tolerant and
imagine the Arizona desert, but that is not the case," said Michelle Solties,
53, owner of Premier Tree and Landscape in Simi Valley. "We use flowering
shrubs like kangaroo paw and feather cassia, and cover like blonde ambition
grass. To learn even more, BeWaterWise.com offers information on
drought-tolerant landscaping and using less water."
According to a report from the State
Water Resources Control Board released in late August, California cities are
cutting their water use. Cities cut water use by a combined 31 percent in July,
exceeding the governor's statewide mandate of 25 percent.
Knowing how and when to water is
crucial. For example, a drip line that outputs one-gallon of water per hour is
often used for shrubs. "But if the shrub requires 15 gallons of water, and you
run the drip line for 15 minutes, you are only giving the shrub a quart of
water," said Carl Brodock, 52, nursery manager for Elegant Gardens Nursery, a
wholesale grower founded in 1999 that utilizes 25 acres in Moorpark. "You need
to run that drip line for 15 hours. Then you might not need to water again for
Lawns can greatly benefit from a
similar watering pattern. Fescue grass lawns, which many people in Ventura
County have, can set roots 3 feet deep. Saturating the soil to a depth of 3
feet means the lawn can go 10 days or more without watering.
Products such as Turf Rescue made by
Agromin in Oxnard can also help homeowners use less water on their lawns. Turf
Rescue is a blend of Cool Planet's CoolTerra biochar and Agromin's Compost 100
organic soil that keeps lawns green while using a reported 35 percent less
water. Biochar is a highly porous charcoal-like material that improves moisture
and nutrient retention in soil.
"Turf Rescue helps your lawn retain
water and nutrients," said Mike Zwerner, in sales and marketing for Agromin. "Whatever type of grass you have — fescue or St. Augustine crab grass — will
stay greener with less water. Your lawn service can help you put down Turf
Rescue, because first you need to aerate your lawn and then spread out Turf

Explaining how roots work and how to
irrigate effectively is important to the success of Maher's and Solties'
services. Because there are ways to help your lawn thrive with less water,
hastily ripping out plants and starting fresh may be a mistake, because
drought-tolerant plants may already been on your property.
"We work with the plants already
thriving, and also find native plants that coexist, and then use wood chips and
gravel to create pathways to nowhere," Solties said. "In order to break up the
yard we put in a pathway that ends at the side of the house or at a wall. We
may design the yard into quadrants and use the paths to make it more
Taking rainwater off roofs,
driveways and streets and channeling it into bioswales and rain gardens not
only helps use rain more efficiently and keep it from simply draining into the
ocean, but it also filters out pollutants that could cause harm to living
"A 1,000-square-foot roof can
capture 600 gallons from one inch of rain," Maher said. "So the home rain
gutter is a key component to passive or active water capture. Bioswales, earth
gutters and rain gardens filter the silt and pollutants from surface runoff,
and then vegetation is planted on the side. Those roots tie into the swale and
live off the water."
Maher said 2015 is the International
Year of Soils, and that soil is the most undervalued resource on the planet.
"Our air has too much carbon and our
ocean acidification is related to too much carbon," Maher said. "Yet our soil
is carbon starved, so connecting the dots with these three elements and using
that bioswale to filter pollution means the answer to climate change is under
