Our corrugated polypropylene inserts are sturdy. But they will eventually wear-out, and need to be replaced with fresh inserts. We flatten them, and run hot water through the channels to remove trapped potting mix, or roots. When the time comes to swap them out for new ones, simply recycle the old ones. This 3 pack of fresh inserts should last for many harvests. Includes:
- 3 corrugated inserts
The inserts have been pre-bent, to make folding them into your planters easy. These inserts are proudly made by Minnesota Diversified Industries (MDI), at their Cohasset, Minnesota facility. MDI provides honorable carreers for those with disabilites.
