Micro Irrigation

Micro-irrigation is a form of low-volume irrigation that uses 30 GPH (gallons per hour) or less versus high-volume irrigation that uses 0.5 GPM (gallons per minute) or higher.

Micro-irrigation is better for plant health, since water is delivered directly to the roots of plants where water can be taken up by the plant. Overhead irrigation can be harmful to plants by contributing to fungal and disease problems, and even in some cases spreading disease by splashing water from leaves of affected plants. Micro-irrigation is also more efficient because minimal water is lost to evaporation.

Micro-irrigation is easy to set up. Simply connect to a hose spigot and a battery operated timer. This way you can easily irrigate to establish drought-tolerant plants and then turn on irrigation only during extreme drought conditions. Micro-irrigation is great for use in landscape beds, in potted containers, and for establishing young trees and shrubs. It is not currently considered to be efficient for watering turf grass.

There are multiple types of micro-irrigation. Four of these include micro-sprayers, drip emitters, bubblers, and in-line drip tubing.
