PLANT YOUR TREES WITH THE PET BOTTLE 

Instead of using polybags for growing saplings, we grow young trees in plastic bottles.  After cutting off the bottom part of the bottle, thus setting the young roots free,  we plant the sapling with the remaining part of the bottle still around the rootball.  Thus, the roots remain undisturbed.  They continue their growth, even in very adverse conditions.  Survival rate is almost 100 % and reforestation a complete success.
