Install Emitters and Tubing
Emitter tubing outlets should be placed between one and three inches above the ground. Proper placement will allow you to observe the wetting pattern for each plant and will reduce the likelihood that dirt from the surrounding area will clog the tubing. Emitters can be placed directly into the poly tubing or anywhere along the micro tubing as long as the tubing outlets are above ground. Above-ground emitters are easier to maintain, whereas underground emitters cannot be chewed by rodents.
- Install micro tubing and emitters prior to planting so water is available immediately after plants are installed.
- Use self-piercing emitters or a hole punch that is the proper size for the emitter. Your irrigation supplier can help you choose the proper hole punch. If you make a mistake, use a goof plug to seal the hole.
- After installing emitters and micro tubing, spot backfill to keep them in place.
