Have you ever turned off your irrigation system in the Fall after the first rain of the season? Its an excellent way to improve water conservation. I have lived in Southern California my whole life, and for the past 15 years, I have turned off my irrigation system after the first significant rain of the season. I left it off until it gets too warm or my lawn tells me that’s enough! Most years, I can leave my irrigation system... MORE >
Irrigation design expert, Dana Seelig has studied and experimented with various approaches to irrigation design over his 30+ years in the profession of landscape architecture. In addition to overseeing the design division’s irrigation system design and development, Dana is responsible for frontend project due diligence, design development and production quality control, agency approvals and field observation services. At the leading edge of irrigation design innovation, Dana has tested new approaches that challenge the typical requirement for time-based irrigation calculations.
Dana has been exposed to the landscape business for most of his life. As a child he raised cacti and orchids with his family, a tradition he continues today, and ran a garden shop for 7 years while in high school and college. In his free time, Dana tends to his orchids, plumarias, vegetable garden, fruit trees and compost, or is found off-roading near his mountain cabin. Dana evaluates water usage for the benefit of his clients and his own assets with both the bottom line and plant health in mind. A commonly overlooked fact that Dana likes to share is the importance of evaluating water requirements for both the plants’ needs and varying soil saturation capacity.
“In order to reduce run-off and encourage healthy plant growth, a soils management report shall be completed by the project applicant,” AB1881 requires. I am totally in favor with the concept that each site has a Horticultural Soils Report that tests for the soils classification, pH, salinity, total soluble salts, sodium, organic matter, and provides a complete set of pre-planting and post-planting maintenance recommendations. The Soils Report should be used in selecting plant material for the site. When high boron... MORE >
In January 2010, AB 1881 went into effect in California, new sections were added to increase the efficient use of water in the landscape. It seems that most landscape architects and agencies are familiar with the new guidelines, but others in the industry have not acknowledged its mandates. The original ordinance, AB 325, was written and created in the middle of a 6-year drought. AB 325 was intended to make sure landscapes were watered efficiently however the tools were not... MORE >
This is something that’s not easy to agree on. In California, we have WUCOLS (Water Use Classification of Landscape Species) to determine the plant factor (crop coefficient); however there is still exposure, climate zone, soils, slope, soil interface between clay, loam (sand nursery soil) and the native site soil. I have found that a majority of our landscape plants can survive with very little supplemental water once established. We have all seen areas where plants survive with very little supplemental...
