Environmental Horticulture / Environmental Science

The goal of environmental horticulture is to preserve and enhance the environment through planting and proper cultural practices for green plants, including shade trees, shrubs, and turfgrass. Environmental science includes preservation and enhancement of environmental quality of soil, water and air. Kern County is a leader in the U.S. in production of rose plants for landscapes and home grounds.
Cooperative Extension provides information on turfgrass, plant selection, cultural practices, arboriculture, landscape maintenance, and pest management.

Horticulture Classes for Landscapes, Gardens, and Orchards
Fall 2018 Class - Special Topics
We will offer a class in Bakersfield this fall that will cover special topics not addressed in the regular horticulture classes. The class will start on October 8 and will meet in our large conference room at 1031 South Mount Vernon Avenue. More details will be available soon, but the syllabus is available for download now.
Classes for 2017-2018
We continue to offer a series of horticulture classes in Bakersfield. Our goals are to conserve water, to enhance and expand green plantings, and to reduce pesticide applications. We will cover practical topics pertaining to planting and care of landscapes, orchards, and vegetable gardens, and offer plenty of time for Q&A and discussion. We welcome individuals who have little horticulture experience, as well as those who work in some aspect of horticulture. Please feel free to contact us for information, 661-868-6200 or firstname.lastname@example.org
Spring 2018: Horticulture for Landscapes, Gardens, and Orchards - Ridgecrest and Vicinity
Beginning 2/13/2018, we will offer a 12 week class in Ridgecrest that is being co-sponsored by the Indian Wells Valley Water District and the East Kern Resource Conservation District. Classes will be held at the IWVWD offices on Tuesday evenings from 5:30 to 8:00 PM.
(Additional note:Kern County does not offer the Master Gardener volunteer program at this time. If you would like more information about that program in California, please refer to the website http://camastergardeners.ucdavis.edu/)
I have offered several horticultural tours, and plan to continue this educational effort. Our heritage of landscape and garden design includes the rich tradition of gardens of several parts of the world, including Europe and the Mediterranean, and some of the world's most interesting and beautiful plant arrangements and collections may be found there. A number of gardens and landscapes exquisitely illustrate design principles and have withstood the test of time. These sights are well worth sharing.
The overall tour objective is to broaden participants' knowledge and appreciation for landscape design and plant selection. The tour also provides an opportunity to experience the flavor of specific countries. Group sizes have ranged from nine to twenty-six.

Green plants contribute volatile organic compounds (VOC) which can enter into atmospheric reactions that form ozone (a pollutant when found close to the Earth’s surface) and secondary organic aerosols. We have conducted a number of research projects pertaining to development of biogenic emission inventories, including measurement of plant VOC emission rates, leaf mass quantification, and evaluation of databases for plant species description. This work also informs shade tree selection for mass planting programs to enhance air quality. A link to selected publications is here.
