large plastic plant pots

Large plastic planters in these listings run from shallow styles about 7" high holding roughly 3.7 gallons up to taller pots around 17–20" high that hold about 12.7–19 gallons. Some rectangular planters are even listed at about 30" tall.

These planters are made from a variety of plastics, most commonly general molded plastic, polypropylene, and polyresin (sometimes described as linear low-density polyethylene). Product listings may use slightly different terms, but they refer to these plastic-based materials.

Double-walled planters provide two main benefits: the full-depth inner wall increases soil capacity and helps insulate roots, while the outer cavity can be filled with sand or gravel to add weight and improve wind stability. Many models also include a marked spot where you can add a drainage hole if needed.

Most listed planters are 'No Assembly Required.' A few taller or multi-piece sets note 'Adult Assembly Required,' sometimes with no tools needed or with basic tools supplied.

Common inclusions are planting baskets, trays, water-level monitors, wheels, starter pots/trays, and plugs for filling outer walls. Product descriptions sometimes note that saucers are not included.

If you need drainage, drill at the marked spot using a 1/4" drill bit through both walls. Indoors, use a protective saucer beneath the planter to catch any runoff and protect your flooring.
