Our earthenware and terra cotta lines are handmade in small factories in Vietnam and China. Fired at high temperatures, these containers are frost-resistant and can stay out all year with proper precautions. These containers are more porous than lightweight or cast stone containers, which allows the roots to breathe.
These containers are made and tested to be frost-resistant, but to ensure that your containers make it through the winter, be sure to elevate them from any surface and make sure the drainage hole is clear. Allowing water to pass through the container without freezing and thawing in or around the container will help damage.
