As trained volunteers, we are constantly learning the latest in research-based practices to advise homeowners how to maintain gardens and sustainable landscapes. Drip irrigation is a method of slowly delivering water to all types of plantings—from planters to gardens to greenhouses.  \nDrip irrigation is not new. In Germany in the 1920s farmers used perforated pipes to irrigate plants. Simcha Blass in Israel  \nWater conservation isone of the nine Master Gardener Priorities  \ndeveloped the first experimental drip irrigation system in 1959 and formed the first drip irrigation company, Netafim, in 1965. Drip irrigation places a precise amount of water where  \nyou need it, prevents overwatering, conserves water, saves money, and keeps water off foliage, reducing disease. It eliminates hours of hand watering, can be fully automated with a timer, and reduces weeding time. Drip systems can be applied to gardens, vineyards, greenhouses, row crops, window planters, deck and patio pots, existing landscapes, hillsides, or flat terrain, and is long lasting and adaptable.  \nA simple irrigation system that many turn to when they first transition from hand watering or overhead watering with sprinklers or spray heads is a soaker hose. Soaker hoses are made from 70% recycled rubber and 30% recycled polyethylene products. They can be bought in 25-ft, 50-ft, and 100-ft lengths. The disadvantage of soaker hoses is that they deteriorate over a few years, and they do not emit water uniformly along their length. More water is distributed atthe end closer to the source. As you reach the end, less water is available for the plants. One can get the best performance from a soaker hose by using a timer, a filter, and a pressure reducer and operating it at no higher pressure than 10 psi.  \nLeft: Pressure compensating shrubbler watering Japanese Garden at the Discovery Garden on Hwy 536 West of Mount Vernon.

Think of a drip irrigation system as a collection of emitters. Emitters allow water to flow out at specified gallons per hour (GPH) . Common emitters allow 1 GPH or 2 GPH flow. The flow of water available from the POC must be capable of providing enough water to satisfy all the emitters. If you plan to have more  \nemitters than your available flow can provide, you must divide your system into zones and then operate one zone at a time.  \nIdentify Your Flow Rate  \nMeasure your flow rate by placing a 5-gallon bucket beneath the POC, open the valve completely, and time the number of seconds it takes to fill the container. Then the gallons per minute (GPM) = (60 seconds per minute/number of seconds to fill) x (number of gallons) .  \nDrip system components.

This will help you determine the amount of mainline and number of branch lines you need. Mainlines are ½”, ¾”, or 1” polypropylene, usually black. Branch lines are usually ½”.  \nThe Parts ofa Drip Irrigation System  \nA drip irriga","cbCaimF0NUX7WUAU","https://ap.wps.com/l/cbCaimF0NUX7WUAU","pdf",1470180,"English","# Drip Irrigation – Design, Installation and Maintenance\n## Step 1: Identify the Water Source\n## Identify Your Flow Rate\n## Step Two: Identify Areas you Want to Water\n## The Parts of a Drip Irrigation System\n## Timers and System Components","[{\"question\":\"What is drip irrigation and why is it useful?\",\"answer\":\"Drip irrigation slowly delivers a precise amount of water where plants need it.
