1. Copper (Cu)
*Role: Activates enzymes, strengthens plant tissues, helps control fungal diseases
* In Trees: Builds stronger limbs and enhances cold tolerance
*In Flowers & Veggies: Supports vibrant color and bloom quality
2. Boron (B)
* Role: Critical for flowering, fruit set, and cell wall strength
* In Fruit Trees: Helps pollination and reduces fruit drop
* In Legumes & Brassicas: Needed for nitrogen fixation and sugar movement
3. Manganese (Mn)
*Role: Drives photosynthesis by helping plants use sunlight more efficiently
* Also: Activates enzymes that fight disease and detoxify stress
*In Corn: Improves early root and shoot growth
4. Zinc (Zn)
*Role: Key for plant hormone balance, leaf size, and shoot elongation
*Without it: Plants look stunted and pale
*In Tomatoes & Fruit: Supports blossom and fruit development
5. Cobalt (Co)
*Role: Supports nitrogen fixation in legumes
* Important for clover, alfalfa, soybeans — helps feed the rhizobia that feed the plant
* Even non-legumes benefit from trace amounts for vitamin and enzyme support
6. Nickel (Ni)
* Role: Small but mighty — involved in urease enzyme, which converts urea into usable nitrogen
* Also helps seed development and root nodulation
* Deficiency can impair nitrogen efficiency
7. Sulfur (S)
* Role: Essential for amino acids (like methionine & cysteine) and chlorophyll
*Enhances greening and nitrogen uptake
* Adds flavor and aroma to brassicas, onions, garlic, etc.
8. Molybdenum (Mo)
* Role: Key for nitrogen conversion inside the plant (nitrate to amino acids)
*Especially important for legumes and crops in low-pH soils
*Works with cobalt and nickel to make nitrogen more efficient

process
How to Use Mike’s Mighty Micros – In 3 Simple Steps:

Step 1: Mix
- Pour 1 ounce of Mike’s Mighty Micros into a clean 1-gallon sprayer.
- Fill the rest of the sprayer with distilled water. Using distilled water ensures the microbes stay active and effective.
💡Using distilled water helps avoid minerals that could interfere with nutrient absorption.

Step 2: Apply
- Lightly mist the leaves of your plant until they're evenly coated — no need to drench.
- Apply every 1–2 weeks as part of your regular plant care routine.
🌱 Foliar feeding allows nutrients to be absorbed directly through the leaves for faster impact.

Step 3: Store
- No need to waste leftover mix!
- Simply seal the sprayer and store it in your shed or a cool, dry place.
- The solution won’t separate or spoil, so you can reuse it the following week.
🧪 Stable formula = zero fuss, no shaking, no clogging

Frequently Asked Questions
Questions? We’ve got you covered
What is the difference between Soil Booster and Biochar?
Our Soil Booster contains Biochar, Worm Castings, and Compost. Our Biochar is a charcoal-like material produced through the heating of organic matter in a low-oxygen environment, which offers a range of long-term benefits for soil health. Learn more on our product pages.
How do I use the micro solution?
The answer is simple - spray the leaves! Our super concentrated blend is best mixed with rain water or distilled water, 1 tsp per gallon about once a week. You can visit our How-To page for more information.
When is the best time to spray?
The best time to spray - is anytime! Since our product is all natural and healthy for the plant, you can start using it to spray the leaves at any time. We typically spray 1-2 times every two weeks.
Can we spray when our fruit tree is blooming?
It's ok to spray plants like strawberries or tomatoes, peppers, etc when they are blooming but apple and pear tree blooms are sensitive to sulfur and it could thin them out.
What if it rains after I spray? How soon should I apply again?
When you spray the leaves wet it is absorbing until it dries. Many variables will change this time. So if it's hot, sunny and a breeze you might only have 20 min of absorbing time. If you spray and the sun is setting or rising and it's calm you could get up to an hour. You can spray the next day if you had a storm after 20 min on leaves but wouldn't make that a habit not only for the risk of overfeeding but the cost and time involved. We recommend watching the weather forecast for optimal times. Sometimes we wait a few days past my spray dates just to get optimal absorption weather.
Does it actually work?
Yes! Our product is made of all natural ingredients that plants actually need to be stronger, and more resilient. This photo shows one plant without our micros, and one with it! Check out ourTestimonialspage to hear from our customers.
Will this help my fruit tree if it has a fungus?
Yes! For example if you had leaf curl, the copper in our micro solution would help to heal and fix it. Our solution also makes plants naturally more disease and insect resistant.
