12. Does the Waterboxx® plant cocoon protect the plant from too much water in the winter?
The Groasis Waterboxx® plant cocoon protects the tree against overwatering. It works as follows:
- The Waterboxx® plant cocoon has an overflow to prevent too much water going to the tree;
- The wick works on the capillary principle: when it is sufficiently humid, it almost stops transporting water from the box to the tree. When it is very dry, the soil gets hygroscopic and the wick’s capillary starts to transport more water;
We plant in ski-resort San Isidro Spain above (!) the tree line. There is a heavy layer of snow on the boxes and the trees from October to the end of May. Immediately after the thaw, it starts to be extremely hot and dry. Please check the video below of our plantation at the ski resort San Isidro in Spain.
