This snippet has been taken from “Firescaping Creating Fire- Resistant Landscapes, Gardens, And Properties in California’s Diverse Environments Wilderness Press Berkeley, CA. California’s water calendar serves over 30 million people and irrigates over 5,680,000 acres (2,300,000 ha) of farmland which is well described by “Tree Trimming Service Stockton CA“
California has definite water calendar cycles. Working within these cycles makes the most of available water makes the most of available water. For lowing are the three simplified water cycles found in California: landscapes below 2,000-foot elevation, the northern coast, and higher elevations.
Summer is the dormant season for the landscapes below 2,000 feet. Coastal scrub, chaparral, and oak woodland are a few of the drought-adapted command ties. The plants within these communities shed older less productive growth and eventually slide into a start of dormancy as water availability declines. Summer their period of rest.
The northern coast differs because of the enormous amount of moisture it receives. Between the rain, which can be as much as 60 inches per year, and the for which can contribute as much as 10 inches of precipitation per year, the landscapes are highly production However, these landscapes can dry out; Mendocino a Eureka have long histories of fire.
Frozen winters and dry summers make the vegetation in the higher elevations some of the hardiest in state. Unlike at lower elevations, soil moisture can remain high, months after the last rain or freeze, However, the demand for this water is great and conifer forests rapidly pull it up, making these landscapes more prone to fire than the plant communism the northern coast. Lassen and Tahoe counties and the Santa Cruz Mountains possess this water cycle.
End of winter to Spring
When the risk of fire is low and a landscape’s growth is at its greatest, water is used sparingly and only to sustain a plant’s growth. Watering before the soil is completely dry the amount of plant fuels; it will deter the exchange of gases in the soil, which is vital to plant health. Watering can typically wait many weeks after the last rain or freeze. Automatic irrigation systems should be turned on when the first 2 inches of the soil are dry.
Summer to Early Autumn
As the risk of fire increases, deep and infrequent watering will keep a landscape’s trees and shrubs less ignitable. Water at this time of year is used to sustain a plant’s current level of growth, and not to encourage new growth. Adaptive, native plants should not be watered but instead be encouraged to go dormant by lack of water.
Autumn to First Heavy Rain
The risk of fire has steadily been climbing and it is now at a point of climax; native and natural landscapes can be tinderbox dry. Zone 1 plants should be kept moist. Zones 2 and 3 plants should get water at least twice a month. While the water will wake the adaptive plants prematurely, the risk of fire demands high moisture content in leaves. However, all watering past mid-October should be shallow and aimed only at sustaining health. Ideally, the ground should be dry before autumn’s first rain.
The garden should be taken off all supplemental water and the irrigation system’s timer should be turned off, a landscape’s water needs are at its lowest. Over watering is common this time of year. Turn on the water only when the top 2 inches of a soil are completely dry.
Time of Day to Water
Along California’s coast, watering should be done in the early morning; mildew and rot are less of a problem if a landscape has a chance to dry, in the drier foothills and mountains, watering should be done during mid-evening, which helps to minimize water evaporation loss.
Timers and Large Irrigation Systems
Automatic watering systems are like politicians: Their goal is not to make everyone happy, but to make the fewest amounts unhappy. Unless the water system is complex and regularly maintained, not all of the plants are going to get the optimum amount of water, which means not every plant will be happy.
However, getting the most out of water is difficult, which is unfortunate because efficiency is not only good for the budge, it improves plant health. Too much water and oxygen is squeezed out, changing the soil’s chemistry. Too little, and die back occurs. Finding the fulcrum takes work.
More likely than not, a local water district will have a calculator on its website (or a link to one) that will help you determine the amount of water to use, and the amount of time needed to distribute that water. These calculators are attached to a series of questions, up to 12 in some cases. To help ascertain the rate of water, these calculators will ask about soil type, planting type, dominant plants, density of planting, exposure, relative heat, amount of area, slope, and, if applicable, type and rates of flow of existing irrigation systems. If large enough, the water district will also have a director whose primary function is to help homeowners save water. Many large irrigation manufactures, such as Rain Bird, have fantastic detailed manuals for designing, installing, and maintaining irrigation systems (these are not the superficial pamphlets passed out at high-volume garden retailers).
