A deep growing taproot is the secret to survival and success of plantings

No plant can survive in eroded, dry or rocky areas without having a sound primary taproot. The characteristic of these areas is that rain falls in short periods, and then drains (percolates) deeply into the capillary canal system of the soil. The only way for the tree to get this water is to have a deeply penetrating primary taproot. If you plant a tree or a shrub with a destroyed primary root, but with well developed secondary roots, it will die unless you use irrigation. If you want to plant in dry areas without irrigation, you must follow the guidelines of the Groasis Technology, which teaches you how to produce plants with intact primary roots. After reading ‘Do I use seedlings or cuttings with the Groasis Technology?’ and  ‘How to make good planting material with the Groasis Technology’, you will then know how to produce the perfect primary taproot.

Look at these fantastic Groasis pictures that show the deeply penetrating primary roots  in the Gobi Desert area of China.
