Trees, the green giants that tower above us, have always inspired a sense of wonder. Their majestic presence sometimes feels other worldly, standing tall through seasons and decades. But have you ever paused to consider what lies beneath their bark or above your line of sight? There is much more to a tree then just its trunk, branches and leaves. Tree Craft Tree Service would like to share the anatomy of tree to help bring more understanding about the needs of your trees.
Underground Tree Roots
The roots anchor the tree to the ground, absorbing water and minerals from the soil. The root is considered the heart of every tree. What many people do not know is that there are types of root systems such as:
• Taproots: Primary roots that grow straight down. They are common in trees like oaks and pines.
• Lateral Roots: These spread out horizontally and help provide stability.
• Fine Root Hairs: Tiny structures that increase absorption capacity.
Maintenance Tip: Mulching around the base of a tree can help conserve moisture and prevent root competition with weeds.
Trunk of a Tree
The trunk supports the tree’s weight, providing a conduit for nutrients between the roots and the leaves. However, a trunk is not as simple as most assume. The trunk consists of a number of components.
• Bark: The tree’s protective outer layer. It guards against pests, diseases, and environmental stresses.
• Cambium: A thin layer of generative tissue. New bark and wood are formed here.
• Sapwood: The part of the trunk that channels water and nutrients upwards.
• Heartwood: The innermost part of the trunk, providing strength. It is usually darker due to stored nutrients and resins.
Maintenance Tip: Avoid damaging the bark. Even minor injuries can expose the tree to infections. If damaged, you can wrap the trunk to help protect the tree from infection or disease.
Branches of a Tree
Branches spread out, bearing leaves, flowers, and fruits. Arborist do consider all branches equal. There are different types of branches such as:
• Main Branches: Originating from the trunk that form the tree’s primary structure.
• Secondary Branches: Sprouting from main branches, with more twigs sprouting from them.
Maintenance Tip: Regular pruning helps maintain branch health, removing dead or diseased parts and allowing sunlight to penetrate the canopy.
Leaves are where photosynthesis happens. They convert sunlight into energy, releasing oxygen in the process. As there are different types of leaves, they are classified into two major groups such as:
• Broadleaf: Flat and wide, usually found in deciduous trees.
• Needles: Narrow and pointed, commonly seen in conifers.
Maintenance Tip: Watch for discoloration or pests. Leaves can indicate the overall health of a tree.
Tree Flowers & Fruits
Flowers are the reproductive organs, leading to fruit and seed production. There are two major groups of flowers found on trees such as:
• Simple Flowers: Like those on cherry trees.
• Composite Flowers: Such as pinecones in conifers.
Maintenance Tip: Some trees might require cross-pollination. If fruit production is a goal, ensure compatible trees are planted nearby.
Tree Crown or Canopy
The crown consists of the tree’s leaves, branches, and sometimes flowers and fruits. It provides habitat for wildlife, shades the ground, and determines the tree’s overall shape. There are two major groups of canopy types:
• Excurrent: Trees with a dominant central stem or leader, like many conifers.
• Decurrent: Trees with a spreading canopy, like most hardwoods.
Maintenance Tip: Thinning the crown can reduce wind resistance and ensure that sunlight reaches all parts of the tree.
