6. Soil Health Pyramid ™: Helping your customers better understand how to develop soil health and fertility

The Soil Health Pyramid™ has been developed to help home gardeners better understand the fundamentals of soil health and fertility. While it makes sense that healthy plants require healthy soil, the questions are—how do I determine the overall soil health and fertility of my soil(s)?, how can I improve my soil to achieve greater soil health?,  how will I know when I’ve achieved optimum soil health?

While commercial growers and farmers often use sophisticated soil and plant tissue testing to better understand the health and fertility of their soils, and certainly the avid and ambitious home gardener can do the same, for the vast majority of home gardeners, the Soil Health Pyramid™ will get the job done.

, Retailer Resources Portal, TerraThrive Retail Products

When customers have filled their shopping cart with a variety of plants—herbs,  vegetables, tomatoes, roses and annual flowers, they are making a considerable investment in their gardens and container pots.

As a garden center sales professional, you should first complement customers on their great plant selections and then pose the question:  “Great plant selection, now tell me a little about the soil your planting those in. Do you have healthy, fertile soils in your garden beds, flower beds, and container pots? How’s your dirt?

Most customers won’t be knowledgeable about the health and condition of their soils.  This is where you can educate your customers, improve the overall health of their soils, improve their growing outcomes (and improve customer satisfaction and loyalty), and make more sales.

The base of the pyramid is COMPOSITION.  The most important aspect of soil composition is the amount of organic matter in the soil. Generally, most soils lack adequate organic matter (5%.)  A simple recommendation is to add compost, mulch, peat moss or manures to the soil to increase organic matter. You currently sell all of these products at your garden center.

The middle of the pyramid is NUTRIENTS or fertilizers. There are a number of organic fertilizer products in your garden center that will fit the bill.  An easy solution is to use an all-purpose, slow-release, organic fertilizer or match the picture on the fertilizer bag to the plants that your customer is buying.  The nutrients or fertilizer will feed the plants throughout the growing season.

At the top of the pyramid is MICROBIOLOGY. This is the new frontier of modern home gardening.  Living soil contains diverse, rich microbial populations of bacteria, fungi and microorganisms that consume and convert nutrients and minerals to highly plant available compounds.  They are essential to soil health and a primary contributor to plant health.

All of the TerraThrive products contain worm castings vermicompost, which is an excellent source of abundant beneficial microbes. Our products work hand-in-hand with the nutrients/fertilizers in the soil to improve nutrient digestion and promote better growing outcomes.

While TerraThrive™ Worm Castings Vermicompost and TerraThrive™ Worm Castings Extract are the best sources of abundant beneficial microbes, and should be applied per the application instructions on the bag or jug, all of our soil mixes and blends contain 10 percent worm castings vermicompost.  We put abundant beneficial microbes (worm castings vermicompost) in all of our home gardening products.

Now, your customers have the soil amendments and nutrients they need to have great growing outcomes.  They have the organic matter, nutrients/fertilizers and abundant beneficial microbes to achieve soil health and fertility. When they have the greenest thumb on the block, they will have you and your garden center to thank for their success.  You will have created a highly satisfied, loyal, repeat customer, and you will have increased your sales of soil amendments and fertilizers, and increased your per customer basket spend.

7. TerraVesco Soil Health Exam: For home gardening enthusiasts

, Retailer Resources Portal, TerraThrive Retail ProductsThe most accurate way to determine the health and fertility of your customer’s soil is with a comprehensive soil test.  We have partnered with two industry leading testing companies, Waypoint Analytical and Biome Makers, to develop a straight-forward, easy to understand soil test for the home gardening enthusiast.

The TerraVesco Soil Health Exam™ follows the fundamentals established in the Soil Health Pyramid™ by examining your customers’ soil’s composition, nutrients and microbiology.

The test includes an analysis of the soil’s pH, soil texture, CEC and organic matter content, as well as a complete picture of both the soil’s nutrient and microbial profiles.

The scientists and agronomists at both Waypoint Analytical and Biome Makers have developed benchmarks for defining soil health so that soil test results can be measured and compared.  This will enable gardening enthusiasts to better understand the deficiencies in their soils and to use products at your garden center to remedy their deficiencies and improve their growing outcomes.

The TerraVesco Soil Health Exam can be ordered directly from the e-commerce shop on our web site at

10. FAQs

How do worm castings improve the quality of garden soils?

As worms consume organic matter in the soil, their digestive tracts grind the food concentrating nutrients an`d introducing abundant beneficial microbes into the soil.  The concentrated nutrients are in a form easily taken up by plants, and the microbes consume nutrients and similarly produce more plant accessible compounds. Worm castings naturally contribute to both Nutrients and Microbiology in the Soil Health Pyramid™.


What makes TerraThrive ™ Worm Castings Vermicompost different and better than other worm castings products in the marketplace?

Several things:

    • Not all worm castings are alike. The overall quality of the worm castings is impacted by the food source (manure, food waste, green waste, paper) consumed by the worms, and the production process utilized to produce the castings. TerraVesco uses only organic dairy manure as the food source, and our proprietary production process, developed over 25 years, produces a high quality, consistent soil amendment that meets the standards of the most demanding growers and farmers.
    • Our products are OMRI Listed and CDFA certified organic
    • No weed seeds and inert materials
    • Vermicompost adds organic matter to the soil improving soil structure and porosity
    • Worm-based soil amendments are our only business


Many soil blend products list worm castings as an ingredient.  What percentage of worm castings in a blend is ideal to maximize growing outcomes?

While many soil blend products list worm castings as an active ingredient, often times the percentages are very low due to the relatively high cost of worm castings compared to other inputs.  And because the soil blender often times did not produce the worm castings themselves, the relative quality of the castings is difficult to access.

At TerraVesco, our commercial field trials and scientific research indicate that the right percentage of worm castings in a soil blend is 10%.  Therefore, when we recommend incorporating our Worm Castings Vermicompost into soil mixes, or mixing into your flower beds, gardens, pots and containers, we recommend mixing in 10%.  In addition, all of our soil blends and mixes contain a 10% allocation to worm castings vermicompost.


Are the TerraThrive products easy to use?

Yes.  All of our products have clear application instructions on the packaging. In addition, the 6 qt and 10 qt bags of TerraThrive™ Worm Castings Vermicompost include a 4 oz scoop for ease of use, and the 32 oz TerraThrive™ Worm Castings Extract spray bottle comes with a four-ratchet sprayer for foliar misting or streaming the extract directly around the base of plants.

The TerraThrive All Purpose Soil Blend™ is designed to implement the Soil Health Pyramid and can be used as a stand-alone soil media for pots and containers.   It can also be mixed with standard top soil to improve the soil health and fertility of   flower beds and vegetable gardens.

The TerraThrive Seed Starter Mix™   is a stand-alone soil media to be used in seed trays and planting pots to promote seed germination and early root development.

If your customers just follow the fundamentals of soil health in the Soil Health Pyramid™, this easy three-step process of mixing in organic matter (compost, mulch, peat moss, manures), adding an organic slow-release fertilizer/nutrients, and incorporating TerraThrive™ for abundant beneficial microbes, then they will have created the ideal soil conditions for their plants to thrive.
