A lot of people think that these are disposable but the best fabric pots are actually durable and reusable. For example, if you are using them to grow seedlings, then take out each when it’s time and reuse the container to grow more.
These are thick enough to handle significant load without ripping. The bigger fabric pots have handles for moving with ease. They have quality stitching to prevent damage and get to the desired spot in one piece.
Despite the thickness, these have excellent breathability which is one of the biggest reasons why people prefer them other pot materials. The root system will continue to benefit from the increased air circulation.
The roots will experience air pruning while temperatures are kept within reasonable levels and excess moisture is drained quickly. Bacterial and fungal issues will be less of a problem.
