How does the porosity of plastic compare to terracotta in outdoor flower pots?
When choosing flower pots for outdoor plants, porosity is a critical factor that impacts drainage and root health. Plastic pots are generally non-porous, meaning they retain moisture longer and require less frequent watering. However, this can lead to waterlogging and root rot if not managed properly. Terracotta pots, on the other hand, are highly porous, allowing air and water to pass through the walls. This promotes better aeration and prevents overwatering, but it also means plants may dry out faster in hot climates. For outdoor use, terracotta’s porosity makes it ideal for plants that prefer drier conditions, while plastic is better suited for moisture-loving species or humid environments. Understanding these differences helps gardeners select the right pot material for optimal plant growth.
