How does the shape of stone outdoor tree boxes affect water drainage efficiency?

The shape of stone outdoor tree boxes plays a crucial role in determining water drainage efficiency, directly impacting plant health and longevity. Rectangular or square boxes often provide more uniform water distribution, while rounded or irregular shapes may create pooling in certain areas. Properly designed boxes incorporate sloped bases and drainage holes to prevent waterlogging. The material thickness and internal contours also influence how quickly excess water escapes. Gardeners should consider both aesthetic preferences and functional drainage needs when selecting stone planters for optimal outdoor landscaping results.
