Deep Irrigation Methods for Training Deeper Rooting networks

HUNTER INDUSTRIES: Root Zone Watering systems

Illustration of the deep underground root watering system by Hunter Industries. This is a intelligent concept especially for warmer drier regions where water is expensive and needs to be desperately conserved. Water better place to store water than deep underground ? But it's also plant engineering smart to establish deeper plant roots in your urban landscape or home gardening projects. In fact with remote site habitat restoration it is an absolute necessity.

I really love all these illustrations. Simple illustrations are such excellent teaching techniques. You know, this  world's leadership (Political, Religious, Corporate Science, Institutions of Higher Learning, etc) have by their very nature been some of the worst communicators when it comes to their lame attempts at educating the public as a whole. This is not true of all, but if you are honest with yourself, you'll have to admit it generally  is the rule. I think Hunter Industries have gone the extra mile  here at intelligently educating the public as to what Nature  actually wants and the RESPONSIBLE Scientific Studies & Literature backs them up. Now the question is are you paying  attention and are you willing to give up the conventional  methods that have failed for years ?

StrataRoot Systems Delivers Water to Roots at all Soil Depths.

Eliminate wasteful run-off  by putting water right where it's needed, in the ground, at the roots. 

(1) Tough plastic mesh allows water, air and nutrients to bypass tough soils and directly reach root systems,

(2) Rugged removable end caps allow easy serviceability of bubblers and check valves. 

(3) StrataRoot delivers water to all levels of the soil structure horizons of your trees or shrubs. Near the surface and deep down.

(4) These reliable Hunter Bubblers are available at .25 or .50 GPM flow.

Just to interject some teaching points here and help educate why most all trees and shrubs prefer deep water uptake, please look at what the science has discovered. These links below which reveal some of the work done by Prof Todd Dawson of University of California at Berkeley prove that Riparian Woodland Habitats foundational trees while clearly growing next to a rich water environment take most of their water hydration from very deep subsoil regions as opposed to the surface areas rich in a wealth of surface water. Now who in their right mind would ever consider such a puzzling phenomena and furthermore question why ? What is it about deep soil moisture that plants actually prefer in summertime as opposed to having a continual supply within the top layers always present ? Even without knowing the exact details to all these questions, clearly it would still be beneficial to replicate just such a system of deep earth hydration. For me, it appears more of a maintenance issue than a growth issue which would also eliminate Pest problems.

Deep-rooted plants have much greater impact on climate than experts thought
But that's the science of discovery and how nature really works. Armed with that kind of knowledge and understanding , you should be able to intelligently engineer your own landscape or habitat restoration project replicating brilliantly complex systems found out in the natural world which will greatly relieve much stress and hardships from your future maintenance workload. But you have to properly proceed and follow responsible steps while Trees & Shrubs are at a young early age.  Wait years down the road and you'll pay for your irresponsible and could care less lazy attitude. It's like raising kids. Most modern day parents are not exactly hands on in continual training of their children from infancy through adolescence. A "Problem Child" could have been avoided, but as a result of ignorance or just the plain laziness of looking the other way and hoping things turn out alright, the parents are shackled to an unfortunate circumstance of their own making. True, sometimes specialized help and therapy can make a correction, but more often than not unlikely and the work load of trying to correct things later can be strenuous and back breaking. 
The Hydro Source

Same with plants, start traing early. Correct any problems early on. Prevent problems like girdling. Retail Nursery container planting systems more than likely will force roots to stay on the surface as opposed to driving deep. Careful pruning of the roots to remove the spinning inside container or even loosening of roots and spreading them out in a wider soil excavation will prevent this situation in the scene below where the tree is being strangled by it's own badly trained root system. And don't forget to inoculate with a great mycorrhizal and beneficial bacterial mix before planting.

Most folks will simply dig the hole, amend soil (waste of money) and bury it again and have a casual attitude of  "Just Add Water". Later in life possible severe corrections have to be made to save the life of the tree as you can see in the photo. Notice how an untrained root system, one with problems early on in life was ignored only to have need of emergency care and therapy later on ? But can corrections be made ? Yes they can, but more often than not it may be to late. See the connection with training kids. Yes often time after the corrections and severe measures taken to reverse a situation, there may be permanent scares for which may never heal and quite possibly be an issue or weakness later on in life.  This will always be a weak spot in the foundation of that tree.

When storms rage then the larger more mature tree is not strong enough to stand up on it's own against such severe environmental forces. Same with young people. Deep emotional scares may never heal and quite often many go to the point of losing their lives because some parent early on gave no thought to problems they saw but ignored. Think about it folks. Both illustrate the same neglect. Even the above neglected tree pruned to late fits this illustration perfectly as any responsible Arborist will tell you.


I have often said I'm not a fan of larger than 1 gallon trees. Shrubs you can get away with some things. But even with one gallon plants, roots should be inspected and corrections made on the spot at time of planting establishment. Now back to irrigation and watering. Drip systems for the first couple of years are okay. Like children again who need milk as infants and later solid food as they mature, so your irrigation methods should change over to a deep watering method after a couple of years. When a gardener/landscaper keeps plants on a drip system, it's like training them to live on life support in a hospital. Remember the jokes about the child who clings to apron strings even as an adult ? They never experience a fulfilled satisfying life and won't know how to care for themselves if that parental support is cut off. Same with Trees and Shrubs. Abruptly take away drip a decade or so later and your tree may die from improper root development.

Early on in the 1970s, I utilizied plastic milk jugs as a crude means of getting water deep into the soil of my remote planted Torrey Pine Trees by placing the jugs upside down in a small hole or depression in the ground at the trees base. Of course it was crude and simple, but it worked. I could often be seen carrying 6 milk jugs full of water up Rattlesnake Mountain several times a week after school or work. Folks still use similar methods today as seen from the Arizona gardener photo. Later I graduated my method by using a long 2 inch PCV pipe plant deep into the earth not far from the plant's base. Crude but it worked. 


In those photos above what is not illustrated is that most of the water will percolate  in the soil very deeply and vertically downwards as opposed to moving towards the horizontal sides in the soil. This is illustrated better by this animation I've used before when discussing remote site planting of Mesquite Dune creation and building methods. You actually want water that deep down and believe me most roots will follow, depending of course on your soil's geological dynamics. Now in the El Cajon Valley in San Diego county where I grew up, water tables throughout most of that giant valley (and I'm sure adjoining city Santee also) are only 10 foot below the the surface. Armed with this knowledge anyone should be able to tap into that system using these irrigation techniques above and having a measure of success. Once that happens watering should be almost eliminated. Of course you can build your own system from scratch, but the Hunter deep root watering system already has the blueprints for an entire underground network with all the fittings. Again it's up to you the landscaper or home gardener. Hopefully some intelligent understanding of how and what Nature wants & needs have sunk in here.
