A thickening agent is a substance that is added to a liquid or mixture to increase its viscosity or thickness. These agents help to create a desired texture in foods, such as soups, sauces, and gravies. Common thickening agents include flour, cornstarch, gelatin, and arrowroot. They work by absorbing liquid and forming a gel-like consistency, giving the dish a more substantial and pleasing mouthfeel. **

Root collar thickening works better because it helps to strengthen the base of the tree, providing more stability and support. This process allows for better nutrient and water uptake, promoting overall tree health and growth.

Overall, root collar thickening improves the tree's resilience and longevity. **

To achieve trunk thickening in bonsai, it is important to allow the tree to grow freely for a period of time without pruning or shaping. This allows the trunk to thicken naturally as the tree puts its energy into growth. Additionally, proper feeding and watering are essential to support healthy and vigorous growth.

Overall, patience and careful observation of the tree's growth patterns are key to achieving trunk thickening in bonsai. **
