We explore how the changing seasons play a significant role in the life cycle of trees, how different species of trees take varying amounts of time to reach maturity, and see how cafefully farmers treat saplings.

Arriving at adulthood is a major milestone in a tree's life. Some fruit trees get there early, maturing at as young as 5 years old, whereas some trees like North American hemlocks can take 300 years to become an adult.

We discover how trees can extend their lives by `walking' across the land and planting new roots, how they can `learn' from trauma, and how a decaying tree has the miraculous ability to nurture new life.
