WHY PLANTERS ROT & DEGRADE

The main cause of planter damage is the direct contact between soil, moisture, and the planter walls.

Over time, this constant exposure leads to staining, rot, and structural breakdown.

OAKENZ liners create a protective barrier between the soil and the planter — reducing moisture absorption and extending the life of the planter.
