What does the sapwood of a tree refer to?

The sapwood of a tree refers to the part that conducts most of the tree's water. This layer is located just beneath the bark and is responsible for transporting water and nutrients from the roots to the leaves and other parts of the tree. The active cells in the sapwood allow it to play a crucial role in the tree's overall health and growth.

In contrast, the inner wood that is no longer active is referred to as heartwood, which typically provides structural support but does not have a role in conducting water or nutrients. The outer bark layer serves to protect the tree from environmental stresses but is not involved in transport functions. Lastly, while some parts of the tree may have decorative qualities, this aspect is not related to the functional role of sapwood in water transport. Understanding the specific functions of these different parts is essential for effective tree care and management, particularly in the context of turf and ornamentals.
