Uro (裏炉) is a technique for creating deadwood in bonsai. It means to hollow out the space where a branch has been removed and preserve it with lime sulfur to give it an aged look. Uro occurs naturally when branches are torn off by strong winds, storms or lightning. Uro is often seen on deciduous trees and adds character and realism to the bonsai.
