Tree propagation is the process of creating new trees from existing ones. This can be done through various methods, including seeds, cuttings, and grafting. Each method has its advantages and is chosen based on the type of tree and the desired outcome. Seeds are the most common way to propagate trees, as they can grow into new plants naturally. However, cuttings involve taking a part of a tree, like a branch, and encouraging it to grow roots. Grafting combines parts of two plants to create a new tree with desirable traits from both parent trees, such as apple trees or cherry trees.
