Specially Formulated for Gardens

Trees, shrubs, flowers and veggies have different requirements than the grass in your lawn. With that in mind, we specifically designed GardenMAX to work best for plants in the garden.

Apply On Top

With all this goodness in one bag, you might think you would have to till it into the soil. Well, we thought of that too and designed GardenMAX to be applied right on top of the soil. No mixing. No tilling. No extra work. Be sure to follow the directions on the bag for best results.


Established Garden Beds

  1. Apply a 3/4” layer of GardenMAX™ on top of entire garden bed. As with any amendment, brush away from stem or trunk of plants.
  2. Rake out any uneven areas.
  3. Water-in thoroughly 3 extra times in the first week to fully dissolve and activate soil treatment then resume regular watering schedule.
  • 1 Bag Covers 4'x4' Area OR 16 sqft
  • 6 1/4 Bags Cover 10'x10' Area OR 100 sqft
Treating a single plant: Apply GardenMAX over entire area from the trunk to 1 1/2 times the dripline to cover root spread area.
Note: If a tree or shrub is located in the lawn or the branches extend over the lawn, treat the lawn area with a 1/4" layer of TurfMAX Soil Treatment for Lawns.

Our passion is turning the places you love into the places plants love to grow. With that passion in mind, we set out to create a product that no matter what soil type you have - or even if your thumb isn’t so green - to allow you to grow a beautiful healthy garden.

You, the earth, your landscape -let’s not make it complicated. It’s all about working with nature, rejuvenating natural processes and supporting life in our soils. The science may be complex but the concept isn’t. It’s natural. It’s just the way things are supposed to work. That’s why we’ve put the time in behind a microscope and in the field developing products like GardenMAX that really make a difference to you, the environment and your landscape. When your trees, shrubs, flowers or veggies need a little TLC, this is the place to start.

Because the ‘circle of life’ in your garden is complex, we’ve been able to combine ingredients in GardenMAX that address a wide range of issues that may be out of balance and causing problems in the landscape. Here is a little insight on how GardenMAX works:

  • Builds Strong Roots- In most cases, the roots of your plants will expand 100X-1000X in the first 6-8 weeks after application! In addition, BioLife Complex in GardenMAX contains some amazing microbes called Mycorrhizae that attach to the roots of plants and extend out into the soil to grab water and nutrients and bring it back to the plant root. This type of teamwork between plant roots and microbes promotes sustainable and healthy growth for the plants in your landscape.
  • Increases Drought Resistance-After GardenMAX expands your plant’s root system (see above), your plants have MUCH greater access to water way down deep in the soil and are more efficient at absorbing it. As a result, your plamts will be better prepared to thrive with less water. In fact, we frequently see clients saving as much as 40% water 6-8 weeks after using GardenMAX.
  • Increases Healthy Growth-Slow growing or unhealthy plants usually results from an imbalance in the soil. GardenMAX treats common problems in the soil and creates an environment where they love to grow. Whether poor growth is stemming from a pH imbalance, nutrient shortage or weak roots, GardenMAX corrects the soil to help your plants thrive.
  • Corrects pH-pH is a measure of the relative acidity or alkalinity on a scale from 0 (more acidic) to 14 (more basic). Most plants prefer a pH near the middle at a pH of 7 or neutral. When the pH balance is thrown off, the health of your garden can severely decline and it will really struggle to stay healthy. GardenMAX corrects pH imbalances within the soil and no matter what the starting point, brings the pH back closer to neutral to keep your garden growing right.
  • Solves Nutrient Shortage-There are 14 plant nutrients that are essential for plant growth. All plants must have an adequate supply of each of these 14 nutrients to be healthy and grow properly. If one or more of these nutrients are lacking in the soil, plants will get sick and start to decline, even though an adequate amount of other elements are available. GardenMAX includes complete fertilizers and restores trace elements back into the soil. This ensures your lawn a healthy supply of nutrients so plants can grow strong and healthy. BioLife Complex in GardenMAX contains some amazing microbes that digest plant nutrients and turn them into a form plants can absorb and use. Just like the bacteria in your gut helps to digest the food you eat, plants need the same type of help from beneficial bacteria to digest their food in the soil. But, it doesn’t stop there, BioLife Complex also includes microbes that are able to pull plant food out of thin air. That’s right, these amazing microbes grab nitrogen right out of the air and can supply a plant with a whopping 30% of its nitrogen requirements.
  • Increases Insect & Disease Resistance- GardenMAX contains NO chemical pesticides, herbicides or fungicides. Instead, we believe it is much healthier for you and your landscape to fight these pests naturally. Powered with BioLife Complex, millions of microbes team up to help keep pest and disease populations in check.


Everyone is Talking about it.

Works on everything

At my gardening guru’s recommendation (Mike Garcia) I’ve put garden max throughout my garden, underneath my Mediterranean Pine, which has shown some wilting. How often and for how long (both per watering and overvtime) shall I water?

Easy to use

No mixing! just apply on top. now thats my style

Better Plants

The plants are definitely greener. All three young fruit trees, a first- and second-year apple tree and a five-year-old cherry tree really loved it!

Great product - heavy bag

Product works great! Just wish I could lift the 40lb bag better...

Works on everything!

I put Gardenmax on everything in my garden. From annual flowers to roses and shade trees and of course my vegetable garden. It makes everything grow better.

bags are heavy

40lbs too heavy for me to carry
