These areas have various problems:

1. Planting before the snow falls and the frost period starts is difficult
2. Many times the just planted trees or bushes die as a cause of frost because their root system has not been developed yet in order to protect them
3. The planting period is very short
4. Planting after the snow has melted is also difficult because the period between cold and warm (or even hot) temperatures is very short
5. This results in a too warm, hot and/or dry climate for the roots to develop fast enough in the mostly rocky soil to create a balance between the water capturing capacity and the water evaporating quantity of the leaves

The Groasis waterboxx solves these problems:

1. You can plant seeds in the waterboxx before the winter instead of plants.
2. By sowing 2 seeds per waterboxx, you are sure that even with a 50% germination you'll have a close to 100% planting result
3. You can plant saplings after the winter period during the whole summer period
4. This gives you the necessary capacity to plant big areas
5. You plant two saplings per box
6. In the next summer you cut the smallest of the two saplings trees if both have succeeded to survive the first winter
7. You can also leave them both
8. If only one succeeded to survive you still have a planting result
9. In general planting with the waterboxx in mountainous areas will give, through using the different methods, a close to 100% planting result
10. If you use the biopolymer model the box can serve as nutrient after being degraded and you have no work taking them off
