The Philosophy Now is Add Everything

The ground has water but we add irrigation. The ground has N-P-K but we add tons of that too.

Why Change?

Some people will say "The soil already has mycorrhizae." If that's the case we should reimburse our customers for all the irrigation we've installed.

Is This Happening?

1Is the soil your planting rich and fertile?
Probably not. In fact, if you think that soil from 5-10.ft deep for the foundation and site work has organic matter, you’re wrong!

2Did the plants come with proper biologicals?
No. Nursery plants are gorwn for speed with artificial fertilzers.

3Having establishment problems?
If you don’t inoculate your root system at planting, your missing the most important step to transition your plantings from the nursery to a natural environment.

They do what they do.

The landscape industry has a misunderstanding on the philosophy, as well as, the scientific reason we apply root inoculates.

We know these organisms function in a certain way. In the presence of food they eat, pee, multiply, and die. This releases nutrients back to the plants to drive growth and the next generation of microbes living symbiotically with the plant. In this study, Wheatgrass was inoculated with Mycorrhizae and planted in an old mine site resulting in increases in growth and colonization.


Our philosophy has always been to mimic natural Soil Food Web with a rich diversity of organisms that work together. In a related article HERE , we explore some fascinating videos of bacteria using fungal hyphae to move around in the soil, further spreading the effects of an initial inoculation.

So knowing that bacteria aid in soil fertility article 1., and that Trichoderma enhances nutrient uptake article 2. , why wouldn’t a landscape contractor add extra of these organisms as insurance, as well as add the most important bridge from the artificial growing methods of the nursery to the natural world?

Root inoculates are the basic building block that give new trees in degraded or destroyed soils years worth of microorganisms at the critical first few weeks of establishment. For 2% of a plant’s cost, it can pay for itself in the savings of just a few plants.

The philosophy is simple. We continuously add massive amounts of soluble fertilizers but the soil already has some. We want more. We spend billions of dollars to irrigate. Why? We want more. MORE GROWTH. MORE COLOR. MORE FLAVOR.

Don’t change the philosophy. Change what you add.

The application of mycorrhizae, zeolite and superabsorbent facilitated the primary establishment of plants by, respectively, 46, 46 and 8 percent. The plant height of the seedlings under zeolites, mychorrhiza and the superabsorbent treatments increased by 65, 54 and 48 percent compared with control,
