Match Your Climate Zone to Your Landscaping Plan

/in , /by

Making smart decisions about your landscape design and your plant choices relies in large part on your climate zone. San Diego County’s six different climate zones vary in their average conditions. By choosing wisely, you can minimize the need for artificial irrigation and still create a beautiful, sustainable landscape.

The California Irrigation Management Information System (CIMIS) divides San Diego County into these six climate zones: Coastal, Coastal Inland, Upland Central, Transition, Mountain, and Desert.

This climate system provides you factors to help you understand which plants will thrive in your landscaping under its native conditions. Gardening in harmony with your local climate zone and your microclimate helps you use resources, including water, most efficiently.

Descriptions of San Diego’s six climate zones

Zone 1: Coastal Prairie

The Coastal Prairie zone hugs our county’s coastline. It is the zone most strongly influenced by the ocean, with a mild marine climate resulting from the warm Pacific Ocean. Winters are mild, summers are cool, and there is almost always moisture in the air.

Zone 4: South Coast Inland

South Coastal Inland areas are just inland from the beach, or on high bluffs above the coastline. You can feel the ocean breeze, but you can’t taste the salt in the air. There is less fog and humidity than the immediate coastal area, and higher temperatures.

Zone 6: Upland Central

The higher elevation Upland Central areas are influenced both by moist coastal air and dry interior air. Humidity, morning fog, and wind are moderate, with low annual rainfall.

Zone 9: Transition

This marine-to-desert transition climate is farther inland. It features a combination of warmer thermal belts and cold-air basins and hilltops, with an occasional marine influence. The climate can vary from heavy fog to dry Santa Ana winds.

Zone 16: Mountain

Steep slopes, variation in sun and wind exposure, shallow soils and heavier rainfall affect plants in the Mountain regions. Average annual rainfall is 30 inches, and wet years can bring 45 inches or more.

Zone 18: Desert

Dry and hot daytime conditions combine with cold nighttime temperatures in the Desert zone. Humidity is very low, and water is scarce. Average annual rainfall can be as low as 2.5 inches, with an average of just 6 inches.

Learn more about the specifics of your climate and microclimate on the California Irrigation Management Information System website.

Opinion: Water Partnerships Between Cities and Farms Would Help Prepare for a Changing Climate

/in , , /by /CalMattersby Alvar Escriva-Bou

San Joaquin Valley farms and Southern California cities are facing different but equally daunting water challenges. For Valley farmers, the requirement to achieve groundwater sustainability in coming years has heightened interest in expanding water supplies to reduce the need to fallow irrigated farmland. For Southern California, falling demands since the early 2000s have reduced water stress during normal and wet years, but a warming climate makes future droughts a major concern.

AJ Carrillo farms 18 acres outside of Hotchkiss, Colo., in the high desert of the Western Slope about an hour southeast of Grand Junction.  When he irrigates his peach orchard, water gushes from big white plastic pipes at the top of the plot and takes half a day to trickle down to the other end of his five-acre orchard. Carrillo is planning to convert his Deer Tree Farm from flood irrigation, which is commonly used in Western Colorado, to a new and much more efficient style of irrigation – microsprinklers.

On a Saturday in late October, Carolyn Phinney stands hip-deep in a half acre of vegetables, at the nucleus of what will one day be 15 acres of productive farmland. “You can’t even see the pathways,” she says, surrounded by the literal fruits of her labors. The patch is a wealth of herbs, tomatoes, eggplants, peppers, kale, winter squash, and zucchini. So much zucchini — fruits the size of bowling pins hidden under leaves as big as umbrellas.

Imagine that you had a bunch of Colorado River water.

Water with some of the most senior rights in the state. The river would have to be virtually dry before your supply was cut.

Now imagine that by fallowing some land and installing more efficient irrigation, you think you can free up a decent chunk of this highly coveted water to lease to others who are in desperate need of more renewable supplies.

Lawn Rebates for Fall Planting Season

/in , /by

Fall planting season is underway and a great time to take advantage of rebates for replacing your lawn.

“Fall is like a second spring for planting in our region and it’s also a great opportunity for residents to take advantage of some outdoor incentives as they replace grass with climate appropriate plants,” said Joni German, water resources specialist at the San Diego County Water Authority.

Lawn replacement rebates

Turf replacement rebates of $3 per square foot are available for residents in the Water Authority service area, she said. The rebates include $2 per square foot from the Metropolitan Water District of Southern California, with an additional $1 per square foot from the Water Authority, for up to 5,000 square feet of lawn converted in front or back yard.

German suggests residential customers use the rebate estimator to determine the amount they would receive for removing their turf.

“For example, if San Diego residents are removing 1,000 square feet of turf, their rebate will be $3,000 – $2,000 from MWD and $1,000 from the Water Authority,” said German.

Free landscape makeover help

For landscape makeover assistance, German encourages residents to visit WaterSmartSD.org, the Water Authority’s conservation website, and take advantage of free landscape education through the WaterSmart Landscape Makeover Program. This program assists homeowners with landscape transformations through a variety of virtual formats including:

  • Three-hour workshops
  • Four-class series
  • Videos on demand

Homeowners can also visit the website to find landscape resources such as free onsite audits, finding a landscape professional, rebates on indoor and outdoor water saving devices, links to programming irrigation controllers, an online plant database and how to install a rain barrel.

Other water-saving practices include turning off irrigation systems when rainstorms are predicted (and leave them off for at least a week after significant rainfall) and installing rain barrels or cisterns to help capture stormwater from roofs and store it for future irrigation use.

“Adjusting irrigation is an easy way to increase water efficiency, since landscapes need less water as the days get shorter and cooler,” said German.

Rebates are also available for weather-based irrigation controllers, soil moisture sensors, rain barrels or cisterns. There are also incentives for commercial customers to increase their water efficiency, with indoor and outdoor rebates. The rebates are processed through SoCal WaterSmart.

Vallecitos Water District Helps San Marcos Coffee Farmer Brew Success

/in , /by

San Diego County agriculture is well-known for citrus and avocados. Kyle Rosa is counting on coffee joining this list.

Rosa, owner of Bluetail Coffee Grove, started growing coffee on a 2.5-acre farm in San Marcos last year. After 15 years in the finance industry, Rosa and his wife moved from San Francisco to start their new venture. The new farmer quickly turned to the Vallecitos Water District for help establishing smart water use and efficient systems to irrigate his six different specific types of coffee.

The Vallecitos Water District offers a free agricultural irrigation audit to ensure its farming customers are using water aligning best with their crop’s specific needs and water-efficiency standards.

“No one has ever done this in the continental United States,” said Rosa. “To be able to be a pioneer and work on something that has never been done and to learn from mistakes is exciting.”

Agriculture audit gauges efficient water use

Lance Andersen, agricultural program manager from Mission Resource Conservation District, performed the audit. MRCD provides free agricultural evaluations to farmers and growers through a partnership with Vallecitos and the San Diego County Water Authority. The agricultural audit examined 2,000 of the Bluetail Coffee Groves trees and 4,000 emitters to see how much water is currently used.

Auditors study how evenly water is flowing across the planting area, so growers can make informed decisions on irrigation scheduling and water management. Post-audit, farmers receive a Google image to assist in the best placement for soil moisture sensor stations to monitor irrigation in real time.

“Lance has been able to give us some pointers as he walked through the farm,” said Rosa. “We have some areas of improvement to add swales to retain water when it rains on our slopes and to prevent soil erosion.”

MRCD also provided information about financial assistance available for the installation of the soil moisture sensors.

Vallecitos Water District assisted Rosa in securing an agricultural rate for his irrigation. He worked with Chris Robbins, Vallecitos Water District supervisor of public information/conservation to start the process.

“He could not have made it any easier for me,” said Rosa.

Bluetail Coffee Grove is an organic farm. Rosa’s farm is undergoing the organic certification process, which takes three years.

Coffee farm plans for eco-tourism

Rosa has ambitious plans to put San Marcos on the coffee map.

“Coffee has a similarity to wine, where the method of creating a cup of coffee is so diverse and so labor-intensive,” explained Rosa. “When you finally get a cup of coffee, everybody has different tastes. Being able to produce those different tastes for a variety of people while having complex notes within our coffee is really what we are striving for.”

Rosa says he hopes his initial business model will work, allowing him to open his farm to eco-tourism.

“The goal is to expand the coffee to have an eco-tourism set up at the farm, where we can roast and try coffee right here and pull the cherries right off the tree and taste the coffee right here for yourself right in beautiful San Marcos, California.”

Before then, Rosa will open a retail store, Breakers Coffee + Wine in the Del Mar Heights area, expected in Spring 2021.
