\n<\/p>\n
Today we\u2019re here in Westover Hills, Texas, working on a Plant Healthcare case where our goal is to identify a potential problem before we allow it to damage an established landscape.<\/p>\n
This property has a water well that is going to become part of the irrigation program. The laboratory water analysis has raised two major concerns that we need to investigate further:<\/p>\n
Elevated salts in the well water and a pH above 9.<\/p>\n
Before this water is introduced throughout the landscape, we\u2019re establishing a baseline by collecting soil samples and sending them to Texas A&M.<\/p>\n
Then we\u2019re going to approach this like Tree Doctors.<\/p>\n
We\u2019re going to establish what the soil looks like today.<\/p>\n
The well company will introduce its water-treatment technology.<\/p>\n
We\u2019ll begin introducing the treated well water into a designated portion of the landscape.<\/p>\n
We\u2019ll physically monitor the plants.<\/p>\n
We\u2019ll monitor soil chemistry.<\/p>\n
And approximately 30 days later, we\u2019ll return and collect another round of soil samples.<\/p>\n
Then we\u2019ll compare:<\/p>\n
Before versus after.<\/p>\n
That\u2019s how we begin separating assumptions from evidence.<\/p>\n
\u2e3b<\/p>\n
When we diagnose declining trees and shrubs, homeowners naturally focus on insects, diseases, fertilizer, and irrigation frequency.<\/p>\n
But there\u2019s another question that should sometimes come first:<\/p>\n
What\u2019s actually in the water?<\/p>\n
Water can appear perfectly clean while containing dissolved minerals capable of influencing soil chemistry over time.<\/p>\n
When irrigation water enters the soil, the water itself may eventually be absorbed by plants, evaporate, or move deeper into the soil profile.<\/p>\n
The dissolved constituents don\u2019t necessarily disappear with it.<\/p>\n
Depending upon the chemistry, drainage, irrigation frequency, rainfall, and soil structure, some salts can accumulate within the root environment.<\/p>\n
That\u2019s why irrigation water should be treated as part of the Plant Healthcare system.<\/p>\n
\u2e3b<\/p>\n
The well-water analysis contains a reported value of approximately 42 ppm for a salt-related constituent.<\/p>\n
Before calling that number \u201castronomically high,\u201d we need to identify exactly what the laboratory measured.<\/p>\n
Was it sodium?<\/p>\n
Chloride?<\/p>\n
Another dissolved ion?<\/p>\n
Total dissolved solids?<\/p>\n
Those are not interchangeable measurements.<\/p>\n
For irrigation suitability, I want to evaluate the complete water analysis, particularly measurements such as:<\/p>\n
This is exactly why we\u2019re approaching the project systematically.<\/p>\n
One number gives us a clue.<\/p>\n
The entire chemistry gives us the diagnosis.<\/p>\n
\u2e3b<\/p>\n
Plants don\u2019t simply \u201cdrink\u201d water like we drink from a glass.<\/p>\n
Water movement through the soil-plant system is governed partly by differences in water potential.<\/p>\n
When soluble salt concentrations increase around the root system, the osmotic component of water potential changes.<\/p>\n
In homeowner language:<\/p>\n
The roots have a harder time extracting water.<\/p>\n
That\u2019s one of the strange things about salinity stress.<\/p>\n
The soil can physically contain moisture while the plant behaves as though it\u2019s experiencing drought.<\/p>\n
\u2e3b<\/p>\n
Depending upon the species and severity, excessive salts can contribute to:<\/p>\n
That\u2019s why the foliage becomes part of our monitoring system during this 30-day trial.<\/p>\n
The plants become biological indicators.<\/p>\n
\u2e3b<\/p>\n
During the trial period, I\u2019ll continue walking the property and monitoring the plants.<\/p>\n
I\u2019m specifically looking for new necrotic tissue.<\/p>\n
Necrosis simply means plant tissue has died.<\/p>\n
If previously stable plants begin developing abnormal leaf-tip burn, marginal scorch, wilting, chlorosis, or premature defoliation after the new irrigation source is introduced, I\u2019m not going to simply wait until day 30.<\/p>\n
That becomes an immediate diagnostic trigger.<\/p>\n
We document what we\u2019re seeing.<\/p>\n
We evaluate irrigation.<\/p>\n
We consider suspending the new water source.<\/p>\n
And we collect additional samples if necessary.<\/p>\n
The monitoring program has to be capable of stopping the experiment before significant landscape damage occurs.<\/p>\n
\u2e3b<\/p>\n
The concern isn\u2019t limited to foliage.<\/p>\n
We\u2019re protecting the soil.<\/p>\n
Repeated irrigation can influence the chemistry of the root zone.<\/p>\n
Depending upon which ions are present, excessive salts can influence:<\/p>\n
This is why we\u2019re taking a soil sample before introducing the new irrigation water.<\/p>\n
Without a baseline, we won\u2019t know what changed.<\/p>\n
\u2e3b<\/p>\n
If sodium is one of the primary concerns in the well water, we have to think beyond simple salinity.<\/p>\n
Excessive sodium relative to calcium and magnesium can negatively affect susceptible clay soils.<\/p>\n
Clay particles can become dispersed.<\/p>\n
Soil aggregation can deteriorate.<\/p>\n
Macropore connectivity can decline.<\/p>\n
That can contribute to:<\/p>\n
Now what began as a water-quality problem becomes a soil-structure problem.<\/p>\n
\u2e3b<\/p>\n
The well water reportedly has a pH greater than 9.<\/p>\n
That\u2019s another condition we need to manage carefully.<\/p>\n
However, there\u2019s an important distinction homeowners need to understand.<\/p>\n
Water pH by itself doesn\u2019t tell us everything about how strongly that water will affect soil pH.<\/p>\n
We also need to understand alkalinity, particularly bicarbonate and carbonate concentrations.<\/p>\n
Two water sources can have similar pH readings but very different capacities to neutralize acidity and influence soil chemistry.<\/p>\n
That\u2019s why laboratory water analysis is more valuable than relying solely on a handheld pH meter.<\/p>\n
\u2e3b<\/p>\n
As soil chemistry becomes increasingly alkaline, several micronutrients can become less available to plants.<\/p>\n
Iron is a classic example.<\/p>\n
Manganese and zinc can also become less available under alkaline conditions.<\/p>\n
The nutrient may physically exist in the soil.<\/p>\n
The problem is bioavailability.<\/p>\n
The plant cannot access it efficiently.<\/p>\n
That\u2019s when we may begin seeing:<\/p>\n
Simply adding more fertilizer may not correct the underlying chemistry.<\/p>\n
\u2e3b<\/p>\n
Highly alkaline irrigation water can sometimes be treated through controlled acid injection.<\/p>\n
But this should be based on laboratory chemistry\u2014not guesswork.<\/p>\n
The treatment requirement depends heavily on the water\u2019s alkalinity.<\/p>\n
We\u2019re not simply trying to make a pH meter display a lower number.<\/p>\n
We\u2019re attempting to manage the chemistry responsibly.<\/p>\n
The well company and water-treatment professionals need to determine the appropriate treatment system, dosage, monitoring, and safety procedures.<\/p>\n
Our responsibility on the Plant Healthcare side is evaluating how the soil and plants respond.<\/p>\n
\u2e3b<\/p>\n
The well company is introducing a technology designed to modify how problematic ions behave within the irrigation water and reduce their negative impact on the landscape.<\/p>\n
That\u2019s their side of the equation.<\/p>\n
My responsibility is different.<\/p>\n
I\u2019m not going to assume the technology works because equipment was installed.<\/p>\n
I\u2019m going to evaluate the results.<\/p>\n
Did soil salinity change?<\/p>\n
Did pH change?<\/p>\n
Did plants develop symptoms?<\/p>\n
Did the soil remain biologically and chemically suitable for roots?<\/p>\n
That\u2019s why we need before-and-after testing.<\/p>\n
\u2e3b<\/p>\n
Before introducing the treated well water, we\u2019re collecting representative soil samples from the designated irrigation area.<\/p>\n
Those samples are going to Texas A&M.<\/p>\n
This gives us a chemical snapshot of the soil before the new variable is introduced.<\/p>\n
That\u2019s our control point.<\/p>\n
Without it, we would be guessing later.<\/p>\n
\u2e3b<\/p>\n
Once the baseline is established, the well company can begin implementing the new water-treatment technology within the designated irrigation area.<\/p>\n
Now the clock starts.<\/p>\n
For approximately 30 days, the treated well water becomes the new variable.<\/p>\n
We aren\u2019t simply waiting.<\/p>\n
We\u2019re monitoring.<\/p>\n
\u2e3b<\/p>\n
This is where Plant Healthcare becomes very practical.<\/p>\n
I\u2019m going to use the landscape itself as part of the diagnostic process.<\/p>\n
We\u2019ll monitor:<\/p>\n
The plants are essentially telling us whether their environment is changing faster than they can tolerate.<\/p>\n
\u2e3b<\/p>\n
I also recommend checking soil conditions approximately once a week during this initial introduction period.<\/p>\n
A quality field pH meter can help us identify trends.<\/p>\n
Depending upon the equipment available, soil EC monitoring can be even more useful when salinity is the primary concern.<\/p>\n
Field equipment does not replace Texas A&M laboratory analysis.<\/p>\n
But it gives us an early-warning system between laboratory tests.<\/p>\n
If something begins moving dramatically in the wrong direction, I want to know before the landscape becomes severely damaged.<\/p>\n
\u2e3b<\/p>\n
I strongly encourage homeowners and property managers responsible for high-value landscapes to understand basic soil monitoring.<\/p>\n
But a pH meter has limitations.<\/p>\n
It tells us acidity or alkalinity under the measurement conditions.<\/p>\n
It does not tell us:<\/p>\n
That\u2019s why field measurements and laboratory testing should work together.<\/p>\n
\u2e3b<\/p>\n
When we\u2019re specifically concerned about soluble salts, electrical conductivity\u2014EC\u2014is one of the measurements I want to follow closely.<\/p>\n
Dissolved ions allow water or soil solution to conduct electricity.<\/p>\n
As soluble salt concentration increases, electrical conductivity generally increases.<\/p>\n
That makes EC a useful monitoring tool.<\/p>\n
Again, it doesn\u2019t tell us exactly which ions are present.<\/p>\n
But it can tell us whether overall soluble-salt conditions are changing.<\/p>\n
\u2e3b<\/p>\n
Approximately 30 days after introducing the treated well water, we\u2019ll return and collect another set of soil samples from comparable locations and depths.<\/p>\n
Then we send those samples back to the laboratory.<\/p>\n
Now we have:<\/p>\n
BEFORE<\/p>\n
and<\/p>\n
AFTER.<\/p>\n
That\u2019s when the investigation becomes much more powerful.<\/p>\n
\u2e3b<\/p>\n
For before-and-after soil testing to mean something, sampling needs to be reasonably consistent.<\/p>\n
We want comparable:<\/p>\n
Otherwise, differences between the two reports could simply reflect differences in where we collected the soil.<\/p>\n
Consistency creates better evidence.<\/p>\n
\u2e3b<\/p>\n
If we reach the end of the 30-day period and:<\/p>\n
The plants remain stable,<\/p>\n
we don\u2019t see new abnormal necrosis,<\/p>\n
soil EC remains acceptable,<\/p>\n
pH and salinity-related measurements remain within appropriate parameters,<\/p>\n
and<\/p>\n
the follow-up laboratory report does not show problematic accumulation,<\/p>\n
then we have evidence that the treatment strategy is performing appropriately during this initial trial.<\/p>\n
That\u2019s very different from simply saying:<\/p>\n
\u201cThe system seems to work.\u201d<\/p>\n
We measured it.<\/p>\n
\u2e3b<\/p>\n
If we begin seeing abnormal necrotic tissue during the trial, the response changes immediately.<\/p>\n
We don\u2019t continue blindly.<\/p>\n
We stop or modify the irrigation introduction as appropriate.<\/p>\n
We document the symptoms.<\/p>\n
We check soil moisture.<\/p>\n
We check pH and EC.<\/p>\n
We evaluate irrigation distribution.<\/p>\n
Then we collect additional samples if necessary.<\/p>\n
Now we\u2019re back to the process of elimination.<\/p>\n
\u2e3b<\/p>\n
This is another important part of being a Tree Doctor.<\/p>\n
If a plant develops brown leaves on day 15, we cannot automatically declare:<\/p>\n
\u201cThe well water killed it.\u201d<\/p>\n
Maybe it did.<\/p>\n
But we still have to investigate.<\/p>\n
Was there drought stress?<\/p>\n
Overwatering?<\/p>\n
Root disease?<\/p>\n
A fertilizer application?<\/p>\n
Herbicide exposure?<\/p>\n
Heat stress?<\/p>\n
Natural dormancy?<\/p>\n
That\u2019s why documentation matters.<\/p>\n
The timeline helps us separate coincidence from causation.<\/p>\n
\u2e3b<\/p>\n
One reason I\u2019m particularly interested in this next 30-day period is that winter is approaching.<\/p>\n
Some deciduous plants will naturally begin losing their foliage.<\/p>\n
Once that happens, we lose one of our easiest biological indicators.<\/p>\n
During the growing season, leaves quickly show us:<\/p>\n
When those leaves disappear naturally, we have less visual information.<\/p>\n
\u2e3b<\/p>\n
The soil doesn\u2019t stop giving us information simply because the leaves are gone.<\/p>\n
During dormancy, laboratory testing becomes even more valuable.<\/p>\n
We can continue monitoring:<\/p>\n
That allows us to continue evaluating the irrigation program even when canopy observations become less reliable.<\/p>\n
\u2e3b<\/p>\n
One of the biggest lessons from this Westover Hills project is that soil testing alone doesn\u2019t always tell the entire story.<\/p>\n
Ask yourself:<\/p>\n
What water are we repeatedly putting into that soil?<\/p>\n
Municipal water.<\/p>\n
Well water.<\/p>\n
Reclaimed water.<\/p>\n
Each source can have different chemistry.<\/p>\n
If you\u2019re managing a valuable landscape, especially with private well irrigation, periodically testing the water can reveal problems before they become visible in the plants.<\/p>\n
\u2e3b<\/p>\n
The irrigation system and the soil cannot be treated as separate worlds.<\/p>\n
Every irrigation cycle introduces water and dissolved constituents into the root environment.<\/p>\n
Plants remove some water.<\/p>\n
Evaporation removes some.<\/p>\n
Drainage moves some downward.<\/p>\n
Certain dissolved constituents can remain.<\/p>\n
Then we irrigate again.<\/p>\n
Over hundreds of irrigation cycles, water chemistry can influence soil chemistry.<\/p>\n
That\u2019s why Plant Healthcare needs to look at the whole system.<\/p>\n
\u2e3b<\/p>\n
The traditional approach is often reactive.<\/p>\n
A shrub turns brown.<\/p>\n
A tree begins dropping leaves.<\/p>\n
Then somebody gets called.<\/p>\n
By that point, substantial physiological damage may already have occurred.<\/p>\n
We\u2019re taking the opposite approach here.<\/p>\n
We\u2019re asking the questions first.<\/p>\n
We\u2019re testing first.<\/p>\n
We\u2019re establishing baseline conditions first.<\/p>\n
Then we\u2019re introducing the change.<\/p>\n
That\u2019s prevention.<\/p>\n
\u2e3b<\/p>\n
I like calling this Plant Healthcare forensics because that\u2019s essentially what we\u2019re doing.<\/p>\n
We\u2019re building a case.<\/p>\n
We establish the timeline.<\/p>\n
We collect evidence.<\/p>\n
We introduce a known variable.<\/p>\n
We observe biological responses.<\/p>\n
We retest.<\/p>\n
Then we compare.<\/p>\n
That gives us something far more valuable than an opinion.<\/p>\n
It gives us evidence from which to make the next decision.<\/p>\n
\u2e3b<\/p>\n
Today in Westover Hills, Texas, we\u2019re sending soil samples to Texas A&M before introducing treated well water into an established landscape.<\/p>\n
The well-water analysis has raised concerns about salt-related chemistry and a pH greater than 9.<\/p>\n
Rather than gambling with valuable trees and landscape plants, we\u2019re establishing a baseline.<\/p>\n
The well company will implement its ion-treatment technology.<\/p>\n
We\u2019ll introduce the treated water.<\/p>\n
We\u2019ll monitor the plants.<\/p>\n
We\u2019ll check field pH and soil conditions.<\/p>\n
We\u2019ll watch carefully for necrotic tissue.<\/p>\n
And in approximately 30 days, we\u2019ll return and collect another laboratory soil sample.<\/p>\n
Then we\u2019ll compare the evidence.<\/p>\n
If the plants remain healthy and the laboratory chemistry remains stable, we\u2019ll have evidence supporting the treatment technology.<\/p>\n
If the plants begin developing abnormal necrosis or the laboratory numbers begin moving in the wrong direction, we\u2019ll stop, retest, and begin ruling out causation before more damage occurs.<\/p>\n
That\u2019s how we approach Plant Healthcare at Arborist USA.<\/p>\n
Not guessing.<\/p>\n
Not waiting until everything turns brown.<\/p>\n
Establish the baseline.<\/p>\n
Monitor the patient.<\/p>\n
Retest.<\/p>\n
Compare.<\/p>\n
Then make the next decision based on evidence.<\/p>\n
