Bonsai muck is a sticky substance that is used to hold bonsai soil on slabs, rocks, or other unconventional containers. It helps to keep the roots of the bonsai tree in place and to retain moisture. Bonsai muck can be made from various ingredients, such as peat moss, akadama dust, sphagnum moss, clay, or keto. Different recipes may have different proportions and consistencies, depending on the desired effect and the type of planting. Bonsai muck can be applied by hand or with a spatula, and it usually hardens after drying
