Plant Pot size Guide and dimensions

Ideally, there are different types of plant pots with a variety of shapes and sizes. The plant pot size will determine the soil level, level of saturation, and the type of plant to be planted in the container based on the plant root system. Using the correct size of a container will ensure plant health. What is the ideal Plant Pot size? The size doesn’t refer to the plant, but refers to the diameter of the pot that it is planted in. When choosing a pot for your plant, choose a pot that is 1-2” (2.5-5 cm) larger than the current size if the plant is currently in a 10” (25cm) pot or smaller. If your current pot size is larger than 10” (25cm) , choose a pot that is 2-3” (5-7.5cm) larger in diameter.
