# What filament is safe for planters and plants?

None of these rows is certified for soil, plants, or food crops. A PLA, PETG, or ASA name is not a plant-safety mark, and this catalog does not store one on the spools below. How long a print survives outdoors is a different question, and these comments do not answer either one.

A planter has two questions mixed together: whether the plastic is an appropriate material next to soil or food plants, and whether the print survives weather. This catalog can answer the certification cell. It is empty on the rows below. Weather is [outdoor filament](/answers/outdoor), [PLA outdoors](/answers/pla_outdoor), and [waterproof prints](/answers/waterproof). Printing ASA in a room is [ABS and ASA fumes](/answers/abs_fumes). [Food contact](/answers/food-contact) is the page for anything you would also call food-safe.
