A natural alternative to chemical pesticides for insects, mites, and mildew.

Micronized sulfur creates a dry, protective layer that insects, mites, and mildew avoid.

Controls many common plant pests without relying on synthetic pesticides or toxic residues.

Works even better when combined with diatomaceous earth (DE) and a small amount of Castile soap so it stays where pests live.Improves soil structure, moisture balance, and microbial life without chemicals or breakdown.

Most gardeners don’t want to spray harsh chemicals on their plants — they just want the pests gone! Micronized sulfur gives you real pest control — without turning your garden into a chemistry experiment.

The Pests This Helps Control

Micronized sulfur has been trusted for generations as a natural option for managing:


  • Spider mites

  • Broad mites

  • Russet & Red mites

  • Aphids

  • Thrips, especially young stages

  • Whiteflies and Mealybugs

  • Psyllids

  • Fungus gnat adults on plant surfaces

  • Scale crawlers (early life stage)

  • Powdery mildew spores


It works best on soft-bodied pests, mites, and early infestations, before populations get out of control.

How Sulfur Works (Simply Explained)

Sulfur works on contact and on the surface.

It:

  • Interferes with insect and mite respiration

  • Makes it uncomfortable for pests to crawl, feed, and reproduce

  • Disrupts mildew spores before they take hold


Pests don’t build resistance to sulfur the way they do to synthetic pesticides — because sulfur doesn’t attack their nervous system. It changes their environment.

How to Use It (Best Practice)

For safety and effectiveness, apply sulfur in water, not as a dry dust.

Per 1 gallon of water, mix:


  • 2–3 oz Micronized Sulfur

  • 3 oz Diatomaceous Earth (DE)

  • Optional: 1–2 oz Castile soap

Shake well before and during spraying.


Spray:

  • Tops and undersides of leaves

  • Stems and branch joints

  • Areas where pests cluster


Apply early morning or evening, out of direct sun.

Using on Houseplants (Important)

Sulfur has a strong odor.

For houseplants:


  • Take plants outside

  • Spray outdoors only

  • Allow to dry

  • Rinse lightly if needed

  • Bring plants back indoors once odor fades


Do not spray sulfur indoors.


When to Apply for Best Results

Sulfur works best when pests are young and active.

  • Start at first signs of insects or mites

  • Reapply every 7 days, as needed

  • Reapply after heavy rain


Consistency beats stronger chemicals every time.



What to Expect (Honest Results)

Micronized sulfur is not a chemical knock-down spray.

What it does:

  • Reduces pest populations steadily

  • Breaks pest life cycles

  • Helps prevent reinfestation

  • Protects plants without harsh residues


Warning — this product obviously smells like…sulfur!

Important Safety Notes

Do NOT Mix with Oils

Never mix sulfur with neem oil or horticultural oils. Wait at least 2 weeks between oil sprays and sulfur use.


Avoid Extreme Heat

Do not apply when temperatures exceed 95°F. Test on leaves prior to full application and follow all directions on label.

Dear Garden Lover,

You may have tried and given up before.


Citrus trees and gardens looking tired, drooping leaves, yellow fruit. You carefully water and fertilize… but everything still struggles.


Let me tell you the truth…It’s not your fault.


Want to know the dirty little secret that I found out?

We’ve all been lied to!


The gardening world is full of products that look fancy… but are actually a net negative.


The Big Chemical companies sell fertilizers are loaded with salts that burn your roots. The Big Box stores stock potting mixes that are decomposing rot that choke your plants, and absolutely everything is lacking beneficial bacteria and fungi!


And even though I invented micro-budding, founded the clean citrus program in Texas, and had all the academic credentials, I still had to experience this pain myself!


My own trees suffered until I discovered what truly matters…the Three Plant Pillars that every plant needs to thrive:


1. Live microbes that unlock nutrients and boost roots


2. Organic fertilizer that feeds, not burns


3. Mineral-based soil that lets roots breathe

That’s why I created Plant Super Boost, Crab, Kelp & Amino Acids (7-4-4), and Super Soil.


To give trees real power. From the roots on up, everything you need and nothing you don’t. Perfected on thousands of plants of every kind.


And if you’ve got one of our micro-budded trees in your hands, know this:


You’re holding science, care, and a little Texas magic.


And you don’t have a brown thumb...you just need the right tools and the right information!
