The Planting a Tree technique in hypnotherapy uses the metaphor of planting and nurturing a tree to symbolize personal growth, healing, and transformation. During the session, the therapist guides the client into a relaxed state and introduces the tree as a representation of their journey, with the tree’s growth reflecting the client’s own development and resilience. This visualization helps the client connect with their inner strength, fostering positive change and emotional healing at a subconscious level.
