Why do tundras lack trees?
Tundra is found at high latitudes and at high altitudes where the permafrost has a very thin active layer. The active layer of tundra is too thin for trees to grow because it cannot support a tree's roots. … The reason is that the permafrost beneath it is like a barrier.

Why are there no trees in the Arctic?
Under a thin soil layer exists permanently frozen ground, or permafrost. The existence of contiguous permafrost is thought to be one of the main reasons why there are no trees in the tundra, because, being permenantly frozen, permafrost has a tendency to hamper root development.
Why are there no large trees in the tundra?
Why are there no tall trees in the tundra? The permafrost freezes the ground so roots can't grow deep.
