Soaker Hose Facts

Steady, deep irrigation results in lush vegetation.

Soaker hoses are an economical alternative to overhead sprinkler irrigation systems. Soaker hoses are sometimes confused with drip systems. Like soaker hoses, drip systems are composed of hoses but hoses in drip systems are fitted with emitters. These emitters attach to nodes on the hose and release water in a steady drip. Soaker hoses are porous and leak water into flower beds or other garden areas.

Benefits

Gardeners who correctly use soaker hoses enjoy lower water bills and healthier plants. Traditional overhead watering systems can damage plants. Wet or damp foliage is prone to insect infestation.

Moisture from overhead watering evaporates into the environment which not only wastes water but causes plants to have underdeveloped root systems. Shallow root systems lead to poor growth and less stability during inclement conditions. Deep watering, which is provided by ground level watering, encourages the growth of healthy root systems capable of withstanding drought and wind.

Types

Soaker hoses can be made from polyethylene or rubber. Environmentally conscious (or frugal) gardeners recycle their old garden hoses by transforming them into soaker hoses. Simply poke holes in the garden hose to create leaks. Other gardeners purchase soaker hoses made of recycled tires and other rubber materials. Be aware that soaker hoses degrade in the sun. Manufactured polyethylene hoses are usually UV resistant. Ask at your local gardening center about the best brands and types for your region.

Installation

Installing soaker hoses is a basic task, about as difficult as attaching a garden hose to a spigot. First, run your soaker hose through the area you wish to water. Do not use a length of hose greater than 100 feet long. There is very little pressure in soaker hoses so excessive length decreases the amount of water flow.

Your spigot should be fitted with a backflow preventer; in many areas this is required by law. Some gardeners attach an automatic timer to their spigot but this is an optional device. Connect your soaker hose to the spigot. If your spigot isn't near your watering area, attach the soaker hose to the garden hose.

Your hose can be placed bare on the ground but you may also cover the hose with 1 to 2 inches of loose mulch. This helps moisture stay in the ground.

Considerations

Soaker hoses are beneficial in many areas of the garden. Flat flower beds and vegetable gardens benefit the most from deep watering but soaker hoses are not meant to be used on lawns. Overhead irrigation is best for this area.

Before purchasing and installing a soaker hose, you should determine if it will be effective for your soil conditions. Clay soils tend to pool water so soaker hoses may be detrimental in compact soil conditions. Sandy soil will draw water downward faster than roots can take up the moisture. Consult with your local master gardeners to decide if soaker hoses are effective in your region's gardens.

Don't use soaker hoses on inclined surfaces or slopes. The water will run downhill without irrigating the plants deeply.

Maintenance

Soaker hoses are the least sophisticated and least expensive alternative to overhead watering systems. The hoses are porous and somewhat flimsy. Soaker hoses must be blown out prior to cold weather or they will expand and break. Leaks and tears can be mended with caulk and other sealants but these fixes are temporary. Over time the hoses become brittle and deteriorate. The hoses are usually replaced when damaged. Many gardeners accept that soaker hoses are short lived and simply replace soaker hoses as needed.
