Large Planter Box (24″ x 24″ x 8′-2″)
Description
This planter measures approximately 24″ wide x 24″ deep x 8′-2″ long.
The design is easily adaptable-you can shorten or widen it to create decorative planters up to 4′ in either direction.
The planter includes a thermal protection system: space for 1 ½″ rigid insulation helps prevent roots from overheating in hot weather. For proper drainage, be sure to:
-
Drill holes in the inner plastic liner.
-
Add 6″ of gravel at the bottom.
-
Cover the gravel with filter cloth to keep soil in place.

Designer’s Notes

The core planter box can be built as a standalone unit for flexible layouts.
-
Always insulate with rigid foam to prevent soil from overheating.
-
Drainage setup (holes, gravel, and filter cloth) is critical for longevity and plant health.
