These soft growing containers allow more air to reach the growing medium and roots, improving drainage and keeping the root system from overheating on hot days. Plant roots also benefit from their natural tendency to grow into soft surfaces like the Smart Pot, becoming thick and healthy instead of circling the inside of the pot and becoming root-bound. These pots are aeration containers allowing the air to prune the plant root structure. Simply remove the containers before transplanting. These pots will help plants become established more quickly after transplanting.
Why Are Smart Pots Better For Growing?
Choosing the best pot for your plants is one of the most important components for successful container gardening. For more then twenty-five years the "Smart Pot" has consistently out performed all other growing containers in both commercial nurseries and university testing. The patented Smart Pot is a soft-sided, aeration container, uniquely designed to improve the root structure of your plants enabling them to grow to their full potential.
Smart Pots are better than plastic containers
Hard-sided plastic containers are relatively inexpensive but they are not a very good home for a plant's root structure. Plastic allows no aeration, conducts and holds heat, and provides inadequate or poor drainage. Even on mildly sunny days, container soil temperatures can easily top 120 degrees, damaging or killing the roots and stressing the plant. The #1 killer of potted or container grown plants is over watering and plastic containers with a few bottom drainage holes actually help the soil stay too wet. A Smart Pot is constructed of a porous fabric that allows heat to dissipate and excess water to evaporate. In fact, over-watering is never a problem because excess water drains and evaporates from all of the Smart Pot's surfaces; its walls as well as its bottom.
Because the Smart Pot is a fabric container, giving the root ball total aeration and excellent drainage, you can even use a heavier, less expensive planting mix. The type of mix used in a Smart Pot is less critical then in hard-sided pots. Also, another Smart Pot benefit is root pruning, a technique used by many commercial nurseries to produce masses of highly branched roots to improve plant quality. When a root grows to the side of the Smart Pot, it stops growing in length and develops many, many fine branches. By contrast, the roots in a plastic pot continue to grow in length when they reach the side and circle around the side of the pot. This is undesirable as there are fewer roots and these can grow around each other causing girdling or strangulation. A branched, fibrous root structure ("root pruned") has a far greater root mass than a comparable plant where the roots are circling on the inside of a plastic pot. And a greater root mass will grow a better plant.
