large garden planters

Elevated planters are designed to reduce bending; typical working heights fall in the low-30s to high-30s inches. Product examples commonly list heights such as 31", 32", 33", 37" and 39" (often summarized as about 31"–39").

Large planters use several drainage approaches: multiple drainage holes, water-permeable or open bases, single drain holes with removable plugs, optimized dual-drain systems, and built-in self-watering or reservoir features on some plastic models.

Common extras include built-in trellises, fabric or removable liners, storage shelves, wheels or casters, greenhouse/PE covers with roll-up doors on some models, and self-watering disks or water plugs in certain plastic planters.

Sizes vary widely by model. Example ranges from listings include heights from about 17.5" up to 65", widths most commonly around 15"–23", and depths roughly 16"–49" — specific dimensions depend on the product.

Planting volume varies by planter size. Examples from listings include small plastic planters at about 0.85 cu ft, mid-size units around 4.2–5 cu ft, and larger beds noted around 10 cu ft. Capacity depends on planter dimensions and design.

Load capacity varies by design: planter boxes or beds commonly list around 110 lbs of soil/contents, some frames or supports are rated up to about 175 lbs, and individual shelves are often specified in the range of roughly 66–110 lbs depending on the model.

Planters use weather-resistant materials and finishes such as rustproof electro-coated metal, naturally treated fir wood for outdoor use, and HIPS/HDPE plastics that resist fading, rot, and cracking. Many models also add reinforced frames or crossbars for extra stability.
