Planter Materials

Planter Materials covers how the container itself shapes plant growth, from soil temperature and drainage to root health. The category looks at wood, metal, stone, fabric and plastic planters, with articles on individual materials. A recurring theme is that appearance alone is a poor guide: a material that looks ideal in one climate can overheat roots or need winter storage in another.

Readers will find comparisons of wood species such as cedar, teak, ipe and pine, and a look at metal options including galvanized steel, corten and aluminum. Other pieces examine concrete for permanence and weight, fiberglass for large or elevated spaces where structural load matters, and fabric grow bags and the science behind air pruning. Terracotta and ceramic are covered for their classic appeal and the care they demand.
