An aerial burr knot on an apple tree appears as a swollen, irregular growth or bump on the trunk or branches, often covered in small, woody protrusions or knobby formations. These knots typically develop above the ground, where the tree's bark is exposed to air, and can vary in size. They are often a result of stress factors such as injury or environmental conditions, and while they may not directly harm the tree, they can indicate underlying health issues. Proper management and care are essential to address the factors contributing to their formation.
