What Causes Knots in Trees

Knots occur in wood when a branch gets embedded in the tree trunk as it increases in diameter. When the branch is living, it creates what is known as a tight knot or intergrown knot. The embedded branch continues to grow with the rest of the tree. Tight knots are firmly attached to the tree.

Why do trees get knots in them?

As a tree continues to grow, its lower branches tend to die off and their bases may become overgrown and enclosed by subsequent layer of trunk wood. This leads to the formation of an imperfection in the tree trunk that we refer to as a knot.

How do you prevent knots in trees?

How to prevent the appearance of knots in trees. By pruning your trees regularly, you can prevent the growth of knots. Cutting off low tree branches and growing shoots can help get rid of possible knots. When branches are badly damaged or dying, removing them quickly prevents the formation of loose knots.
