Okay kiddo, so you know how trees grow naturally? They start small and grow bigger and bigger until they're really tall and strong. But sometimes people want to make trees look special and pretty, and that's where bonsai comes in. Bonsai is when people take small trees and cut and shape them to make them look like miniature versions of big trees.
Now, sometimes when a big tree is growing in the wild, there are parts of it that die because they don't get enough water or nutrients. These parts are called "deadwood." In bonsai, sometimes people intentionally create deadwood areas on the tree to make it look more interesting and even older.
To create deadwood on a bonsai tree, first the tree is pruned and shaped to look like a miniature version of a big tree. Then, the areas of the tree that are going to be made into deadwood are carefully scraped and sanded until the bark is removed. This leaves a really cool, smooth texture that looks like the wood on an old tree that's been out in the sun and wind for a really long time.
After the deadwood is created, it's important to treat it with a special solution to help preserve the wood and protect it from pests and disease. Then, the tree is watered and cared for just like any other bonsai until it grows bigger and more beautiful over time.
So basically, deadwood bonsai techniques involve intentionally creating areas on a bonsai tree that look like the old, weathered wood on a big tree in the wild. It takes a lot of patience and care, but the end result can be really cool and unique!
