Founder, Dave Allen’s roots began back in 1999 when he was a partner in a small manufacturing company. They produced mesh cylinders that channeled water, oxygen and nutrients into the ground around trees. Always preoccupied with a need to know how things work and what improvements could be made, Dave worked with researchers at Davey Tree Company (one of the oldest and largest tree care companies in the world). There they field tested what impact if any mesh tubes, or more specifically channeling water, oxygen and nutrients around the rootball, had in the establishment of newly planted trees. The measured results were nothing short of significant. A few years later models were designed to connect into high pressure irrigation systems which to this day are sold through the Rain Bird sprinkler company.
Around 2004 Dave branched off on his own and started the RZI company. More than a dozen new tree and shrub products were designed including an internal tube water deflection device. The device prevents water that enters through the top of a tube, from flowing directly out of the bottom. By inserting the device into mesh tubes, irrigation is defected out of the side walls into the root zone area within the soil. This device named StrataRoot has been sold globally by Hunter Industries for the past decade, in a variety of models.
