Plant Health Care in St. George & Southern Utah
Yellowing leaves, insects and borers, disease, or a tree that just isn't thriving — our certified arborists find the cause and treat it. Free estimates across St. George and Southern Utah.
Most tree problems have more than one possible cause, and the wrong treatment costs you a season. So we diagnose first: what the damage looks like, where it started, and what the soil and water are doing. Then you get a straight answer about what's wrong, what it takes to fix it, and whether it's worth treating.
Fertilization, insect and pest control, disease and fungus treatment, iron chlorosis, and water stress — on trees and shrubs, across Southern Utah.

Tree Fertilization & Deep Root Feeding
Lawn fertilizer feeds grass, not trees. Deep root fertilization injects a slow-release feed into the root zone, below the turf, where the tree can actually use it.
More
We look at the species, its age, and what the soil is giving it before recommending anything. Most trees do best on a feeding once or twice a year, timed to the season. Younger and newly planted trees usually need more.
Tree Insect & Pest Treatment
Aphids, scale, mites and borers each need a different treatment. We identify what's actually on the tree first, then use the least aggressive method that will work.
More
Sticky leaves and sooty mould usually mean something is feeding on the sap above. Small round holes and fine sawdust at the base usually mean borers, which is the more serious call.
Borers are worth calling about early. Once they've tunnelled through enough of the trunk, no treatment brings the tree back.
Tree Disease & Fungus Treatment
Leaf spots, powdery coatings and branch dieback look alike from the ground, and the wrong treatment costs you a season. Diagnosis comes first.
More
We look at the pattern of damage, which parts of the tree are affected, and how it's spreading. Treatment might be a fungicide application, a change to how the tree is watered, pruning out infected wood, or a combination.
Some diseases are managed rather than cured, and we'll tell you plainly which one you're dealing with.
Yellowing Leaves & Iron Chlorosis
Yellow leaves with green veins means iron chlorosis — iron locked up in our alkaline soil. Surface iron rarely fixes it; trunk injection puts it into the tree directly.
More
Results usually show in the next flush of growth. Yellowing can also come from water — too little in summer heat, or too much from an irrigation system built for lawn, not trees.
We check both before treating, because treating the wrong one wastes your money.
Is your tree trying to tell you something?
Trees show stress long before they die. Here's what the common warning signs usually mean — and what we do about them.

Common questions about tree health
Most people call us because something looks wrong and they're not sure how serious it is. Here are the questions we get asked most.
Not seeing your question?

Why are my tree's leaves turning yellow?
If the leaves are yellow but the veins stay green, it's usually iron chlorosis. Southern Utah's soil is alkaline enough that iron is present but locked up where roots can't take it in. If the whole leaf yellows evenly, it's more often a water problem — too little in the heat, or too much from an irrigation system set up for lawn rather than trees.
Both are treatable, but they need different treatments, which is why we diagnose before we do anything.
Can a dying tree be saved?
Often, yes — if the roots and trunk are still sound. Trees that look dramatic from the outside can recover well once the underlying cause is fixed.
Some can't. Advanced borer damage or extensive root rot passes a point where no treatment brings the tree back, and at that stage the honest answer is removal. We'll tell you which situation you're in rather than sell you a treatment that won't work.
What is deep root fertilization?
Nutrients are injected under pressure into the soil around the root zone, below the level where grass roots take everything first. Surface fertilizer mostly feeds the lawn; this puts the feed where the tree's feeder roots actually are.
How often should trees be fertilized?
Most established trees do well with one or two feedings a year, timed to the season. Young and newly planted trees usually need more while they're getting established, and a tree recovering from stress or disease may need a different schedule.
It depends on species, age, and what the soil is already providing, so we'd rather look before recommending a schedule.
Are treatments safe around kids and pets?
Our applicators are licensed, and we use the least aggressive treatment that will solve the problem. Where a treatment needs time before the area is used again, we'll tell you exactly how long to keep children and pets off it.
If you have specific concerns — a vegetable garden nearby, a dog that digs, beehives on the property — mention it when you call and we'll factor it into what we recommend.
How much does tree treatment cost?
It depends on the size and number of trees, what's wrong, and which treatment the diagnosis calls for. A single fertilization visit and a multi-year disease management plan are very different jobs.
The estimate is free and we'll walk you through what each option costs before anything is scheduled.
How soon will I see results?
It varies by treatment. Insect problems often show improvement within a couple of weeks. Iron chlorosis usually corrects with the next flush of new growth, so treating in late summer may not show much until spring. Fertilization works over a season rather than a week.
We'll tell you what to expect and when, so you know whether it's working.
Do you treat shrubs as well as trees?
Yes. Shrubs get the same pests and diseases trees do, and they're often the first thing on a property to show signs of trouble.
