My Montmorency tart cherry gave me six pies, more than ever. I used Amplify from late March, and I honestly think it made the difference. Karen H. Traverse City MI.

★★★★★ My bell peppers always seemed to stall in August when the heat hit. Started Amplify this spring, and they just kept going, bigger fruit, thicker walls, still producing into September when they usually give up. I used it on my jalapeños, too, and those went absolutely crazy. Frank D. · Bucks County, PA Verified Buyer

★★★★★ I got a little overzealous in June, was applying Amplify almost every week because the early results were so good I thought I could push it further. Then I noticed my tomato plants were getting very tall, very fast, but not setting as much fruit as I expected for their size. Lots of lush green growth, not enough flowering. My husband said they looked like they were trying to win a height contest. I backed off to every two or three weeks, and things balanced out beautifully; the plants stopped racing upward and started putting energy into fruit. Ended up with a fantastic crop. The product works best when you let your plants tell you the pace, not the other way around. Donna K. · Westerville, OH Verified Buyer

What Healthy Roots Actually Look Like

Most gardeners never see this part of the plant. But root structure determines how efficiently plants absorb water and nutrients—and how reliably they grow above ground. Amplify is the only thing you can apply that supports this.

Amplify signals your plants to grow a denser, more active root system.

This is where water and nutrients are absorbed. It is the foundation of stronger, healthier plants without more of your effort.

Amplify sparks your plants to grow roots outward and downward.

Instead of circling and limiting growth, healthy roots expand outward and downward—supporting stronger, more resilient plants.

You've put years into your garden. Amplify helps show it.

Better roots mean more consistent results - across your vegetables, lawn, shrubs, and containers. Everything you grow, performing closer to its potential.

Learn more: the science behind Amplify

Amplify is derived from Hen of the Woods, a well-known edible mushroom, through a careful 3-year fermentation and pasteurization process. The result is a stable, concentrated liquid containing natural signaling compounds that interact with plant biology at the cellular level. There are no live organisms in the bottle. No synthetic chemicals. Just the compounds that tell your plants to open up and absorb more of what's already in your soil. Safe for vegetables, herbs, fruits, trees, flowers, lawn, and houseplants. Safe around pets and children once applied.

How to Use - It's simple

Frequently Asked Questions

Is Amplify fertilizer?
No - and that's the point. Amplify doesn't add nutrients to your soil. It signals your plants to absorb more of what's already there. Keep using your regular fertilizer alongside it. The better fed your plants are, the more they have to draw from.

How often should I apply Amplify?
Between 1 and 4 times a month. Temperature, humidity, what you're growing, and how your plants are responding all factor in. You know your garden best. Watch how your plants respond and let that guide your rhythm.

SOIL: Apply more frequently in denser soils, such as clay types, or in soils that drain quickly, such as sand.
LOCATION: If you garden in a dry, low-humidity area, apply more often.
PLANTS: It can be used on any plant, but apply it more often if the plant is woody, such as trees, shrubs, and vines, including roses.
PLANT RESPONSE: You know your garden best, so watch the plant response; it will vary across your garden, and increase or decrease application frequency based on what you see. Do not overapply, start out slowly, less is more.

Is Amplify safe?
Completely. Amplify is derived from Hen of the Woods, a common edible mushroom, and pasteurized. No live organisms, no synthetic chemicals. Safe for vegetables, herbs, fruits, flowers, and lawn. Safe around pets and children. Follow label directions.

How long does one gallon last?
One gallon of Amplify concentrate makes 16 gallons of mix. Less than $3.75 per treatment. Applying more frequently during the season is normal and still cost-effective. Every 8 ounces of concentrate mixed into water covers about 300 square feet. 1 gallon of Amplify concentrate mixed into 16 gallons of water covers about 3500 square feet. Less than 2 cents per square foot.

Can I use it on Vegetables, Lawns, Shrubs, and Flowers?
Yes. Everything. Vegetables, fruit trees, flowers, perennials, lawn, shrubs, containers, and houseplants. If it grows, Amplify works on it.
