Plastic pots are lightweight, strong and flexible. They are available in every color of the rainbow to coordinate with interior and exterior decor. Plastic does not have the wicking action that clay has making them an excellent choice for moisture-loving plants or for those gardeners who water infrequently.
Plastic pots are made of inert materials and are considered safe for growing plants. Many are made of recyclable plastic so disposal is environmentally friendly when the pot is no longer usable (unglazed clay pots are fully recyclable as well). Plastic pots generally have thinner walls than their clay counterparts offering roots little if any insulation from temperature change. Black plastic can actually act as a solar collector, heating up the potting medium to plant damaging levels.
