Irrigation and Palm Trees

Zone 9b | Tony V added on May 14, 2019 | Answered

For numerous reasons I need to install an irrigation (sprinkler) system to my backyard. And yes the pics show that I need to neaten up a bit, so I understand that as well. The area is higher than other parts of the yard and has two levels that are stepped by use of railroad ties. The top level has the taller trees, mostly tropical. It will also have ground cover and vines to cover the wall that runs along our property. The second level has shorter plants and flowers. The taller tree level is my initial concern. Among the trees are King Palms, Queen Palms and Giant Birds of Paradise. Under a couple of the Queens are Asparagus Foxtail Ferns. From what I've read so far, ideally bubblers would be the best choice for the palms. Would I need to place one on each side of the palms, so two each, whether or not they have the Foxtail under them? Some of the trees are close to each other; can they share a bubbler? Lastly, will bubblers be okay for the Birds of Paradise and again will I need two each? All these trees are established, but will be adding another Bird and a Queen as well. How can I water the ground cover, yet avoid hitting the palm trunks? I live in a 9B with the native soil being rocky and sandy? The bubbler I'm considering is the "Toro Flood Bubbler Riser Full Circle with Adjustable Flow". For the ground cover I'm considering a standard riser, but not sure. The lower level will be irrigated on a separate valve and line. I'll address this in a separate post later. Open to suggestions, except for a drip system. Had one for years and have fought it every step of the way. I also have plenty of PVC, so prefer going that route. Tony

This extension job with existing mature palms and structures will need to be looked at by a qualified landscape architect. This level of work would be beyond my expertise. A professional is the only way to insure the survivability of your palms, plants and hardscape areas.
You can hire them to draw up a a plan and then still do the work yourself or hire out what you would like to be done by other sub contractors.
