Micro-irrigation

Trickle emitters, also called "spider sprays," come in fixed or adjustable radius shapes and diameters, and are installed directly on the flexible supply pipe or on tubing connected to it, and mounted on small stakes.

Trickle emitters work well for plants with more fibrous root systems, tree and large shrub basins, and in pots and container gardens—allowing automated watering on decks and patios.

In the horticulture industry, wholesale growers and plant nurseries often use trickle emitters for 5-US-gallon (19 L) and larger container stock, to automate watering.

Attached to longer supply tubing on short stakes, they are easily movable to new containers when stock is moved or sold.

[2] This allows a larger volume of water to reach the flowerpot in a short amount of time, which will then be absorbed into the roots of the plant.

[citation needed] Low-flow irrigation systems are used on native plant habitat restoration and environmental remediation projects.

The lower operating pressure can be the only choice for remote locations with wells or small storage tank water sources.

It is used in temporary installations during initial establishment periods, and on the soil surface is easily removable with minimal damage to the recovering plant community.
