## Overview

Watering gardens requires considerable expense during the summer growing season. Garden centers use an effective method of drip irrigation to water ornamental plants. Efficient water use translates to home water conservation through the use of soaker hoses. These hoses feature lengths of recycled rubber punctured with tiny holes. With light water pressure, the holes drip water slowly into the garden soil for an effective deep-watering method.

### Step 1

Measure the length of the garden hose from end to end. Soaker hoses generally provide 30 gallons of water per hour for each 100 feet of hose. Manufacturers recommend using smaller lengths of hose (25 and 50 feet) to provide consistent, even watering.

### Step 2

Multiply the standard figure of 30 gallons per hour by the decimal fraction of .25 (25-foot hose) or .50 (50-foot hose). This figure provides the amount of gallons per hour provided by the length of soaker hose. For example, 30 gallons per hour multiplied by 0.25 equals 7.5 gallons per hour.

### Step 3

Determine the general square footage of the garden plot by measuring garden length and width. Multiply these two figures to acquire the square footage area of the garden plot. For example, 10 feet length multiplied by 10 feet width equals 100 square feet of garden space.

### Step 4

Use the standard requirements of 1 inch of water per week to adequately water most landscape plants. One inch of water equals 0.62 gallons of water per square foot of garden space. Multiply your garden measurement by 0.62 gallons. For example, a 100-square-foot garden multiplied by 0.62 gallons equals 62 gallons of water to apply the recommended 1 inch of water per week.

### Step 5

Divide the total gallons of water for the garden's square footage by the output (in gallons) of the soaker hose. The example uses a 25-foot hose that emits 7.5 gallons per hour. A 100-square-foot garden needs 62 gallons of water in one week. Divide 62 by 7.5 gallons per hour. The resulting figure of 8.2 hours indicates the amount of time required to water the garden using a soaker hose. Space this required amount of time over the week for best results.
