Detroit Garden Works Composition Campana Urns

Composition stone is a durable, cast material designed to mimic natural stone. It is weather-resistant and heavy enough to remain stable in most garden environments, though it should be protected from extreme freeze-thaw cycles to prevent cracking.

No, the urns and their square bases are separate pieces. This design makes them easier to transport and position, and you can use a small amount of outdoor-rated construction adhesive if you prefer to secure them permanently.

To preserve the natural patina, avoid harsh chemicals or pressure washers. A gentle rinse with a garden hose and a soft-bristled brush is sufficient to remove surface debris.

Yes, these urns are designed with drainage holes to ensure proper water flow. We recommend adding a layer of gravel or landscape fabric at the base before adding soil to keep the drainage clear.

While composition stone is durable, it can be porous. If you live in a climate with harsh winters, we recommend covering them or moving them to a sheltered area to prevent water from freezing inside the material and causing damage.
