Select ceramic for indoor style, polyethylene or all-weather plastic for outdoor durability, or coated metal for strength and rust resistance

Check drainage options

Prefer boxes with built-in drainage holes or liners and consider coco fiber liners for improved aeration and moisture control

Match mounting hardware

Pick adjustable brackets for varied sill depths or railing planters with included liners if you need a secure outdoor install

Size for plants and space

Measure sill or rail depth and choose lengths that allow adequate root room for intended plants, like succulents or herbs

Weather and maintenance

Look for weather-resistant finishes or all-weather plastic to minimize upkeep and reduce risk of cracking, fading, or rot
