With so many different types of nursery pots to choose from, you may be left wondering what is the difference or why does it matter? The answer is simple, performance. One of the biggest influences on performance is air pruning.
Air pruning is the introduction of dry air into the root system. When this happens the apical cells at the root’s tip become dehydrated. The plant responds by growing a pair of secondary roots that branch off of the initial root. Each time the media dries out, the process repeats itself creating literally thousands of offshoot roots. This vigorous root system is much better at mining soil and increasing nutrient uptake. Air pruning also prevents the plants roots from literally strangling each other, a process known as spiraling.
