When do you think that buds appear on trees? In the spring? Or maybe at the end of winter? Well, trees actually form their buds during the summer, usually in August! Since trees are dormant during the winter, they don't have the energy to grow structures that are that small and complex! Buds aren't very apparent in the fall and throughout the entire winter. In the spring, however, they swell and are ready to open.

Trees produce their buds at the end of summer. This occurs during what is referred to as lignification, when trees get ready to face the upcoming winter. Trees do all their growing in early summer. In late summer, they store up reserves to begin the growing process again the following spring.
