    We have been using your product with all of our trees since April 2009. Our first experience was with a commercial bid which was extremely tight with money. We planted 90 Spruce trees and agreed to a two year guarantee. We traditionally are an up-scale residential contractor and we have a long history planting spruce trees. They are the most difficult trees for us to transplant. Our experience is now different. In the past 17 months we have replaced only 3 trees out of the 90 on the job I mentioned. Thank you for a great product and instant service. We don’t plant without DIEHARD.

    I’ve used Diehard in my garden and yard. I love how it improved the plants health, color, growth. I’ve also shared this with friends and family. And have found it works great with our bamboo we have just planted. I will always add biologicals to every plant I install as well as my lawn.

    We’ve used your product now for over a year. I’ve been in the business for over 15 years and have never been able to plant trees and walk away the way I can using DIEHARD Transplant. We simply do not lose trees anymore. MJM Design Group Odessa, Florida

    We move trees and shrubs from 3gal balls all the way to using our 90″ tree spade. Die hard has become a must for all B&B applications. We have a stellar survival rate and can really see the difference in root growth. On one project where 2 12″ caliper willow oaks were moved and unfortunately died due to the client’s lack of desire to water we upon replacement noticed the HUGE volume of root growth after just 8 months in the ground. It was defiantly due to diehard.

    Our firm Down To Earth has been using your products for over two years. We being a large commercial contractor install mainly 4″ and larger trees. Your products have increased our clients satisfaction, eliminated die-back and reduced fertilizer requirements. We have experienced superior growth, root development and nutrient uptake. While we must budget for the products, they do pay for themselves in terms of client confidence. Long term benefits have not been realized, but I expect we will win more bids due to our quality of installations.

    We are commercial Landscape contractors. The spring of 2006 we were starting to install the second phase of a housing community. Specifically, building the landscape and irrigation infrastructure for the community surrounding the houses. Along the main spine road which runs through middle of the project we were to plant a vegetative buffer for the multifamily buildings. This included relocating some 30′-35′ Oak trees from phase 3 to this buffer. The relocation went fine. No, we did not use Diehard! Following the transplanting, irrigation bubblers were added to meet the individual watering requirements of these oaks. The trees flushed out with new foliage. They looked great, everyone was please. They would provide a great buffer in the years to come! Well not really. A week or so later, the largest of the trees, in the middle of the buffer, was brown. Following some quick investigation and dealing with instant displeasure from our client we discovered the problem. As commonly occurs with construction sites, the water supply had been shut off. A few days earlier, a contractor had hit the irrigation mainline, shut off the water, made the repair and forgot to turn it back on. This was not good. After years of transplanting oaks I knew that if the tree flushed in the spring and then lost its leaves for what ever reason it was done. Especially, in this case. This was a transplant. Not a container grown tree that had not lost a good portion of its original root system in the root pruning over that past six months. I told my client and my landscape manager to remove the tree to the trash pile. I would come up with five or seven tall palms to replace the canopy and in a year the buffer would be reasonable again. My client agreed with my assessment as there were not any trees left on the site to relocate. I left the site in my landscape managers’ hands. A week later at our weekly meeting I inquired about the replacements. My landscape manager informed me that they would not be needed. I was annoyed with his response, when he informed me that he had excavated around the tree and added diehard and increased the watering regiment. I told him that this was a wasted effort and weeks would pass with a dead tree in the middle of the site. This is not the best advertising! He insisted on giving it a chance. Three weeks later the tree flushed for a second time. Late spring 2007. I saw the tree last week, it is thriving. This is the only time I have seen a tree so far gone come so far back from brown dehydrated limbs to thriving. A couple of changes have taken place as a result. We employ the use of Diehard for many things now in our landscape and transplanting efforts and I don’t question my Landscape manager’s judgment.

    Being a Landscape Architect I am always looking for the edge that will make my project better than the others. With the use of this product (since May 1998) we have less call backs and better looking trees.” Thanks for your efforts and superior products.

    I don’t know exactly how this stuff works, but I have planted nearly 500 tangerine trees using your product and they are all thriving. I have a neighbor with the same variety who didn’t use your product, and his trees are scrawny in comparison.
