Trust the leader. Trust the DIEHARD™ brand.

Dramatic differences, every time!!

With over 100 ingredients, our transplant product “naturalizes” the ground and plant root system dramatically reducing transplant shock and establishing the transplant much faster.

Results matter!

At the end of the day, the success of a well-designed landscape project is reflected by the condition of the plant materials both initially and once they are established.

The biggest “black box” in the industry is the condition of plants from the time they leave the nursery until they are established in the landscape. Often the landscape site contains little “life” in the ground where the planting is taking place.

Nursery grown plants have been grown in a much accelerated fashion with little thought to developing and nurturing the natural systems that all plants have evolved with. These systems, including natural immune systems, are not present in plants from a nursery, but are absolutely necessary for symbiosis in the landscape for plants to flourish.

Our products address these issues by including over 100 ingredients to “energize” the ground with over 70 strains of beneficial bacteria, biostimulants to “naturalize” the ground and multiple species of mycorrhizal fungi.

With our products, we’ve “stacked-the-deck” with ingredients that universities have proclaimed (in tens of thousands of studies); and forward thinking, industry professionals have begun to use in the recently. Think of how many proven plant and micro flora technologies you have learned about in technical conferences. How would you like to use all, or most of them, in a single product?

Now you can. We’ve been improving the way landscapes take hold for over 17 years. Our customer retention rate is over 75% with our biggest market to landscape contractors where the products are not specified. The ingredients we put into our products everyone knows about, but very few take the time and trouble to search out and use, much less combine them for efficacy and an AWESOME Landscape! We’ve taken all the guess work out of using these technologies and offer our experience and tenacity to make your planting projects more successful.

Writing The Specification

When writing the specification for a soil amendment product, the wording must be specific or, as you know, some contractors will simply not use any product. Mentioning the use of a mycorrhizal transplant product in several places will result in a higher percentage of estimators that will bid the project correctly.

An effective specification will list the number and quantity of organisms and ingredients and leave no room for interpretation. If you require ingredients specifically, you will get good value for your client and superior plant performance. Specify ingredients, not trade names. Use our calculator/specification sheets to determine how many pounds are needed by the contractor and to correctly list the ingredients that ensure expected results.

Call Jim Quinn if he can help you to get this done.

Usage Calculator

If the specification does not require a verifiable receipt, it disadvantages legitimate contractors that are including it in their bids, thus enabling the less-than-correct contractor.

"HORTICULTURAL ALLIANCE DIEHARD™products are amazing! We have used DIEHARD™ TRANSPLANT for Mitigation Tree installations for several years, and have had a zero loss factor for the 300+ trees we have installed each year."
 
 

Hi, my name is Jim Quinn.

I started the company that brought super absorbents to the markets in the early 1980’s.

In 1996, we put together a full line of mycorrhizal inoculants for arbor, landscape and reclamation complete with biostimulants, beneficial bacteria and water and nutrient absorbing gels.

I have been working closely with professional landscape architects for over 25 years.

We attended the ASLA Annual Meeting almost every year for the past 25 years.

I know what problems are likely on projects. You, too, know these problems. How many things can go wrong?

You have a plan for most of the pitfalls to get the project done responsible and now there’s something you can do about transplant issues.

Using DIEHARD™ products will make a huge difference for your clients, your firm and your piece of mind.

If you want to see this difference, put billions of live organisms into the ground with your own transplants.

YOU WILL!
I guarantee it!

Respectfully,
James J. Quinn
