The highly anticipated 2nd Edition - California Master Gardener Handbook has arrived and is available online for purchase to the public. The California Master Gardener Handbook has been the premiere choice for gardening enthusiasts on the West Coast since it was first published in 2002.

The trusted California Master Gardener handbook is a valuable resource that is packed with research-based information and more than 21 in-depth home horticulture topics. The handbook offers advice on home vegetable gardening, plant propagation, landscape design, insects, water management, weeds and much much more!

What's new inside?

The completely redesigned handbook has updated tables, graphics and color photos throughout. Technical information has been updated by University and industry experts and the handbook is more reader-friendly with a reorganized flow of information.

“The second edition handbook has been a true labor of lots of hard work and dedication and the result shows! The handbook includes many updates and expanded coverage of important topics of interest to UC Master Gardeners and avid backyard gardeners as well. The Water Management chapter include timely topics such as use of graywater and more coverage of edibles than the first edition. Controlling Garden Pests Safely, Landscape and Garden Design, Poisonous Plants and other chapters have been updated and expanded to reflect accurate information pertinent to the needs of today's environmentally-conscientious gardeners.” - Janet Hartin, Environmental Horticulture Advisor, San Bernardino, Riverside and Los Angeles Counties and UC ANR Environmental Horticulture Associate Editor 

New content was added on important topics including invasive plant species and designing and maintaining landscapes for fire protection. The poisonous plants chapter was completely rewritten by Judy Alsop, the former Director of the Calif. Poison Control Center, and there is an expanded chapter on water management in the home landscape.

From a majestic oak, giant sequoias or a swaying palm there is nothing quite as beautiful in this world than a tree. They can provide us with shade, fruit, flowers and most importantly are the “lungs of planet”.  While we have enjoyed some wet weather over the last week, California is still suffering from extreme drought conditions.

Prioritizing Trees for Landscape Water Use

Many residents have been encouraged to reduce water use by turning off their outdoor watering systems, but this may be causing stress to established trees that are becoming increasingly thirsty for water.

In most traditional residential landscapes trees are surrounded by turfgrass. Turfgrass surrounded trees take advantage of the frequent and shallow watering schedule, typically set to help the lawn flourish. When residents eliminate or reduce water for lawns, trees cannot easily adapt to the new water shortage.

“Mature fruit trees and landscape trees are worth saving! Recognizing early signs of drought stress is important because irreversible damage can occur that no amount of watering will correct.” said Janet Hartin, UC Cooperative Extension advisor in a recent article, Save Water, But Also Save Trees During a Drought.

Replacing small plants, lawns and shrubs is easy compared to a large tree which takes years to become established. Saving mature trees during a drought should be a top priority in your landscape water use allocation.

“Two seasons without enough water can result in severe drought stress and even kill a tree,” warned Hartin. “Also, drought-stressed trees are more prone to damage from diseases and insects than non-stressed trees.”

Understanding how to water a tree effectively is important to avoid water waste and to ensure that the tree is receiving the correct amount of water for its survival.

One key factor to successfully watering a tree is understanding what soil type is present. Understanding soil types is an important factor in determining how much water is stored in the ground. For example, sandy soils dry out quickly while clay soils retain more water. Contact your local UC Master Gardener Program to learn how to determine your soil type.   

Another important factor is understanding tree anatomy for watering (see Figure 1). The tree roots of a mature tree are found in the top three feet of soil and extend outside of the tree's canopy. This outside area of the tree roots is the most active absorption area.

Tree Ring Irrigation Contraption (TRIC)

Recently the Calif. Center for Urban Horticulture (CCUH) at UC Davis, UC Division of Agriculture and Natural Resources (ANR) and Ewing Irrigation devised a unique watering system called the Tree Ring Irrigation Contraption (TRIC).   Using previous data from Netafim drip tube tables and from the Irrigation Association Landscape Irrigation Auditor manual, the partners envisioned a possible solution to mitigating drought conditions and the effect on landscape trees.  The TRIC is an inexpensive kit that homeowners can put together for around $100 for one large tree.  

The TRIC could enable homeowners to adequately water trees to a depth of three feet with confidence, by using the recommended parts and using the TRIC calculator with accurate information. Aside from a recommended parts list, there is a “plug-in” calculator created by Dr. Loren Oki, UC ANR Associate Specialist in Cooperative Extension Landscape Horticulture for UC Davis & UC ANR. The TRIC calculator helps determine the run-time needed for the device.

With more than 650 participants, including 48 break-out sessions and four keynote speakers there was a wealth of knowledge and experience available to all that attended the triennial 2014 UC Master Gardener Conference.

Welcome & keynotes

To kick-off the conference internationally acclaimed speaker and park ranger, Shelton Johnson, inspired the crowd during his welcome to Mariposa and Yosemite introduction. Johnson is a supporter for exposing minorities to National Parks and connecting them back to the natural world. He has also dedicated a majority of his work around the history of the Buffalo Soldiers and their roles in National Parks during the early 1900s.  During his welcome speech Johnson embraced UC Master Gardeners as a passionate group who had an evident love of nature, soil and the earth.  

Two keynote speakers followed Johnson's inspirational welcome, Doug Tallamy a professor in Entomology and Wildlife Ecology at the University of Delaware, and Alan McHughen a public sector educator, scientist and consumer advocate for UC Riverside. Tallamy, author of “Bringing Nature Home”, presented the importance of biodiversity in our ecosystems.

“Replacing half of the area that is now barren lawns with plants that are best at supporting food webs would create over 20 million acres of connectivity [nationally] and go a long way sustaining biodiversity in the future,” encourages Tallamy. 

The opening day's final keynote speaker, Alan McHughen, presented on what every UC Master Gardener should know about genetically modified organisms (GMOs). His presentation was focused around his research findings, published in “Pandora's Picnic Basket”. McHughen explained the basics of rDNA technology and how it is used in agriculture and horticulture.  

A magical night at Tenaya

Attendees experienced a “Magical Night at Tenaya” presented by volunteers from the UC Master Gardeners of Fresno County. During the welcome reception guests enjoyed appetizers under the stars while a pianist played on the terrace.

The silent auction was a huge success with many counties donating beautiful baskets of local goods and handmade items. The total raised from the silent auction was more than $6,400! All of the money raised will go to offset the cost of registration for the 2017 conference.

Of the $6,400 raised, $600 was set aside for need-based scholarships.  We're happy to announce the statewide UC Master Gardener Program and UC ANR are matching the $600, bringing the total up to an impressive $1800 to support need-based scholarships in 2017.

Sessions, sessions, and more sessions!

Day two of the conference was dedicated to track sessions.  With six breakout rooms and eight different session times there were 48 potential topics for UC Master Gardeners to absorb. Activities ranged from a hands-on propagation workshop and gardening during a drought to UC Master Food Preserver presentations. The array of options for conference participants made 2014 the most diverse UC Master Gardener event to date.

Visit the conference website to download some of this year's most memorable presentations. Many generous speakers have offered to share their presentations for future reference with conference attendees, visit the conference website to view the uploaded presentations.  

Following a full day of learning, attendees were invited to join together in the grand ballroom for dinner. Renee Shepherd, owner of Renee's Garden, joined UC Master Gardeners for dinner as the night's keynote speaker. Shepherd discussed her pioneering career in the seed business as well as future trends in the gardening industry. She also explained the differences between heirlooms, hybrids and open pollinated seed varieties during her presentation titled, “A Seedy Business”.

Search for Excellence Winners and Honoring Pam Geisel 

The final day of the conference started with three inspiring presentations from the 2014 Search for Excellence winners. Riverside, Santa Clara and Orange counties presented their winning projects to conference attendees.

Following the winning Search for Excellence presentations was attendees enjoyed a heart-warming celebration of gratitude for Pam Geisel, honoring her years of service to the UC Master Gardener Program. Geisel began her career with Cooperative Extension in 1981 as an environmental horticulture advisor. In 2006, Geisel became the first statewide director of the UC Master Gardener Program, helping to establish the program under the UC Division of Agriculture and Natural Resources (ANR) and doubling program reach before her retirement in 2013. UC ANR's Associate Vice President, Bill Frost, was at the conference to recognize Geisel for her contributions to the program and awarded her with the 2014 ANR Distinguished Service award for Outstanding Leadership.

The conference's final keynote presenter, Dan Heims of Terra Nova Nurseries, delivered a presentation on “Humor from the Horticultural Trenches” with many outrageous remarks and requests from the perspective of a garden clerk. Before attendees got on the road to travel home, a generous donation of plants from Monrovia were awarded to some lucky attendees.

See you in Southern California in 2017

Many thanks to the numerous volunteer, host counties and conference planning committee members who made the 2014 conference a reality.  Without their dedication and support the conference would not have been possible. We look forward to reaping the harvest of our success in growing together at the 2017 UC Master Gardener Conference in Southern California.
