Microirrigation is a way to water plants using low pressure and low flowrates (usually 15 psi or less and 60 gph or less). Microirrigation systems can be easy to install above, on, or below the soil or mulch in landscape beds and are inexpensive to purchase. This 3-page fact sheet discusses types of microirrigation systems, benefits, design and installation, and maintenance.
