provides adequate water for pots up to 10 inches wide. An elbow fitting takes the tubing over the pot edge at a 90° angle; a U stake keeps the tubing and emitter in place.

Two emitters are attached to a T fitting
This configuration will water medium-size pots up to 15 inches wide. A notched stake holds the tubing in position.

Multi-outlet emitter
(sometimes called a bubbler) can be used to thoroughly water the soil in a large container. It can be adjusted to change the spray.

Quarter-inch tubing
hides along the base of a wooden planter, then follows a crack to the top of the container. (For brick or concrete walls, drill holes with a masonry bit and use masonry nails.)
