Your shrubs are thinning. Your trees are struggling. The soil is usually why.
Most tree and shrub decline in South Florida isn’t a maintenance problem. It’s a nutrition problem. Alkaline soil locks out iron. Sandy beds drain nutrients before roots can absorb them. Most plant care programs treat the symptoms above ground without ever addressing what’s causing them below it.
No synthetic pesticides. No herbicides. No inputs we wouldn’t be comfortable explaining to you in plain language.
Let’s take a look at what’s going on
We’ll walk the property, tell you what we see, and explain what we’d do differently, and why. No sales pressure, no commitment required.
Beautiful landscaping declines gradually, and usually for reasons nobody told you about at installation.
South Florida’s alkaline soils lock out iron and manganese even when they’re present. Sandy beds drain nutrients before roots can absorb them. Heat and humidity stress trees and shrubs year-round in ways that a quarterly spray schedule wasn’t designed to handle. The result is a landscape that looked great at planting and has been quietly underperforming ever since. Not from neglect, but from the wrong program.
What we’d ask before hiring a tree and shrub program.
These are the questions we wish more homeowners asked, and the reasons we built Granuly the way we did.
What’s so different about South Florida soils?
Our programs are built specifically for alkaline pH, sandy beds, and the nutrient-availability issues that make plant care here so different from anywhere else. We live here. It’s all we do.
Are you fixing the root zone or just the foliage?
Treating yellow leaves doesn’t fix what’s causing them. We work at the root zone first, improving soil chemistry and nutrient availability so the plant above it can actually recover and stay healthy.
Do you ever use pesticides, herbicides or toxic chemicals?
No synthetic pesticides. No herbicides. No micronutrients sourced from industrial byproducts. We use only inputs we can fully explain, and we will if you ask.
Will the program be calibrated to my actual plants?
Ixora, Clusia, Gardenia, and Live Oak all have different nutritional needs. We build every program around the specific plant material on your property. Not a generic rotation that treats everything the same.
Who answers when something looks off between visits?
You talk to the person running your program. Not a call center. If a shrub starts declining between visits, you get a real answer from someone who has actually been on your property.
Will you check the soil before recommending anything?
Always. We walk the property and review the existing plant material before we suggest a single thing. No program starts before that conversation happens.
Ixora needs iron. Gardenias hate alkaline soil. Generic programs don’t account for any of that.
South Florida’s most common landscape trees and shrubs each respond differently to the same soil conditions. Ixora turns yellow without consistent chelated iron. Gardenias struggle in high-pH beds. Cocoplum and Clusia respond dramatically to proper root-zone nutrition, while Bougainvillea needs almost none of what those plants require. A program that applies the same inputs to all of them isn’t a plant care program. It’s a schedule.
We build nutritional programs around the specific species, soil conditions, and goals of each property, so shrubs grow fuller, trees establish stronger root systems, and the landscape actually performs at the level you were expecting when you had it installed.
Yellowing leaves and thin growth are symptoms. The cause is almost always underground.
Alkaline soil pH locks out iron and micronutrients, making them unavailable to roots even when they’re technically in the ground. Sandy beds drain faster than plants can absorb. Surface treatments can make a plant look better temporarily. Fixing the soil chemistry makes it actually get better.
Trees aren’t shrubs. And the soil doesn’t treat them the same.
South Florida’s landscape trees and shrubs each have their own nutritional realities. What works for a Live Oak doesn’t work for an Ixora, and what an Ixora desperately needs is wasted on a Bougainvillea. Here are the species we work with most often, and how we think about each.
Trees
Trees are long-term decisions, and they decline slowly enough that you don’t always catch it. What goes into the root zone in year three shows up in year ten as canopy density, color, and structural integrity. Most established trees in South Florida landscapes are running on whatever nutrition was applied at installation, plus whatever the lawn program happens to drift over. We treat trees as the multi-decade investment they actually are.
Live Oak
The quintessential South Florida shade tree. Drought-tolerant once established, but susceptible to manganese deficiency (frizzletop) and gradual decline in our alkaline soils when the root zone goes neglected. Topical sprays don’t fix the underlying chemistry. Root-zone nutrition and proper mulch do.
Gumbo Limbo
Native, hurricane-resistant, famously called the “tourist tree” for its peeling red bark. Generally low-maintenance once established, but underperforms during the first few years without adequate root-zone nutrition. We focus on getting the establishment phase right so the tree doesn’t spend its first decade barely catching up.
Mahogany
A beautiful native canopy tree, slow grower, increasingly popular as South Florida landscapes mature past their planting phase. Often planted and forgotten, then declines gradually from cumulative micronutrient deficiency. Proper micronutrient calibration maintains canopy density and color over decades, not seasons.
Royal Poinciana
Iconic for its summer red bloom and one of the most recognizable trees in South Florida. Deep, aggressive root system, but it can struggle in compacted or poorly drained soils. Benefits more from soil structure work and phosphorus availability than from nitrogen pushes that mask the real issue.
Shrubs
Shrubs are the workhorses of every South Florida landscape. They form the privacy lines, the structure around the residence, and the seasonal color. They also show stress fastest, which is usually the first sign something underground is wrong. Each species below has its own nutritional reality, and the programs that ignore those differences are why so many properties replace the same plants every few years.
Ixora
The yellow-leaves shrub of South Florida. Iron-loving and constantly chlorotic in our alkaline soils because high pH locks out iron even when it’s present in the ground. The standard fix is topical iron spray, which masks the symptom for a few weeks. Addressing the soil chemistry is how it actually gets better.
Clusia (Pitch Apple)
The default hedging shrub in many South Florida landscapes. Drought-tolerant, salt-tolerant, generally low-maintenance, but responds significantly to root-zone nutrition, especially when it’s being grown as a privacy hedge that needs to stay dense, full, and not gappy at the base.
Cocoplum
A native hedging shrub, highly salt-tolerant, durable in coastal landscapes. Works hard in conditions that kill other shrubs, but most properties install it in difficult spots and then never set it up for long-term health. Soil-first programs make the difference between a hedge that thrives for decades and one that gradually thins.
Bougainvillea
Flowering, drought-tolerant, and the most over-fertilized plant in Florida. Heavy nitrogen produces leaves, not flowers. A program that knows when to pull back is what produces dense color through the dry season. Most plant care programs apply more product more often, which is exactly the wrong move for Bougainvillea.
Gardenia
Notoriously fussy in our alkaline soils because Gardenia wants acidic conditions and gets the opposite. Constant yellow leaves and gradual decline are the norm unless soil chemistry is actively managed. Many properties just replace the plant every few years. We’d rather correct the soil and let the original plant thrive.
Hibiscus
Florida’s flowering icon. Prone to mealybugs, scale, and chlorosis, and the standard response is insecticide sprays that mask the underlying issue. Healthier plants resist pests on their own. Better nutrition and balanced soil chemistry do more for long-term Hibiscus health than any spray rotation.
Palms and ornamental beds have their own programs.
Palms have their own nutritional realities, especially around potassium, manganese, and magnesium, and run on a separate Palm Care program. Annuals, color beds, smaller ornamentals, and groundcovers are handled under our Ornamental & Landscape program. If you’re not sure which fits, we’ll walk through everything at the assessment and tell you.
Not just looking better after a visit. Actually getting better.
Here’s what we’re working toward, and what we’d tell you to watch for as a genuine measure of whether the program is doing its job.
Fuller, More Vibrant Shrubs
Nutritional programs that produce denser, more colorful growth, and reverse the gradual thinning and fading that happens when soil chemistry goes unaddressed for years.
Root Systems That Actually Establish
Root-zone inputs that improve establishment, drought tolerance, and long-term plant structure. Especially important for recently installed or struggling plant material that never got the foundation it needed.
Fewer Deficiency Cycles
Correcting the underlying soil chemistry means deficiency issues come back less frequently, instead of treating the same chlorosis or decline on the same plants every season.
We look at your plants before we recommend anything.
No guesswork, no pre-loaded proposals. Every Granuly Tree & Shrub Care program follows the same three steps. Starting without understanding what’s actually wrong is how you end up treating the same symptoms indefinitely.
Walk the property and evaluate the plant material before anything else.
We review the existing shrubs, trees, and structural plantings, assessing species, visible health indicators, soil conditions, and problem areas before a single input is selected. Your program starts with what we actually found, not a generic proposal.
The right inputs for the specific plants on your property.
Applications are calibrated to species, soil pH, seasonal growth cycles, and the nutritional gaps most impacting plant performance. We account for the differences between what’s growing on your property, not just what’s easiest to apply across all of it.
A program that improves alongside your landscape.
We track how plants respond and refine accordingly. The goal is a landscape that needs fewer interventions over time, not one that requires the same rescue treatments on the same plants every season.
A landscape that performs the way it looked at installation.
- Fuller, more colorful shrubs with better growth and density over time
- Stronger root development and improved establishment for trees and woody plantings
- Targeted correction of iron chlorosis and micronutrient deficiency, the most common issues in South Florida shrub beds
- A cleaner program: no synthetic pesticides, no herbicides
- Species-specific care calibrated to what’s actually growing on your property
This program is a good fit if…
- Your shrubs are thinning, yellowing, or underperforming despite regular maintenance visits
- You’ve invested in landscape installation and want it to hold up long-term, not just at planting
- You want plant care that addresses what’s causing the problem, not just what’s visible
- You’d rather have a program built around your specific plant material than a generic spray schedule
And what we actually say.
Why are my shrubs turning yellow?
Yellowing between leaf veins, called iron chlorosis, is one of the most common problems in South Florida shrub beds. It’s caused by alkaline soil pH locking out iron and other micronutrients, making them unavailable to roots even when they’re technically in the ground. Addressing the soil chemistry directly is how it actually gets corrected, not just masked.
Is this just fertilization?
Fertilization is central to the program, but the approach is built around what each plant actually needs. We evaluate specific species, address soil chemistry issues, and time applications around how the plants respond. Not a fixed calendar that applies the same thing to everything on a rotation.
What plants does this cover, and what doesn’t it?
This program covers the trees and structural shrubs that form the backbone of South Florida landscapes: Live Oak, Gumbo Limbo, Mahogany, Royal Poinciana, Ixora, Clusia, Cocoplum, Bougainvillea, Gardenia, Hibiscus, and others. Palms have their own nutritional realities and run on a separate Palm Care program. Annuals, color beds, smaller ornamentals, and groundcovers fall under our Ornamental & Landscape program. We’ll walk through what you have at the assessment and tell you which program fits.
Do you use pesticides or herbicides?
No. The program is built to improve plant health through better nutrition, not chemical intervention. No synthetic pesticides, no herbicides, and no re-entry windows to manage after a visit.
Does this include pruning or trimming?
The program is focused on nutritional care and plant health. Pruning and trimming are separate. If you’re unsure what’s covered or want to talk through it, we’re happy to walk through everything at the assessment. No pressure to decide anything on the spot.
My plants look bad. Is it too late to help?
In most cases, no, but the sooner we start, the better. Schedule a free assessment and we’ll give you a clear picture of where the plant material actually stands, what’s causing the decline, and what realistic improvement looks like from here. We won’t oversell it.
We’ll tell you what’s actually going on with your plants, and what we’d do about it.
No obligation, no hard sell. Just a walk through your property and a straight answer about what’s causing the decline, and what we’d recommend to fix it.
