What's the best way to level uneven cast iron outdoor planters?

Uneven cast iron outdoor planters can be frustrating, but leveling them is simpler than you think. Here are the best DIY methods:

1. Use Shims or Wedges: Place rubber or wooden shims under the low side to stabilize the planter. This is a quick, non-permanent fix.

2. Adjust with Gravel or Sand: Fill the base with gravel or sand to add weight and adjust the balance. Tilt the planter slightly to redistribute the material.

3. Grind or File the Base: For a permanent solution, carefully grind down uneven spots on the cast iron legs or base using a metal file or angle grinder.

4. Install Adjustable Feet: Attach screw-on leveling feet to the bottom of the planter for precise adjustments on uneven surfaces.

5. Use a Leveling Mat: Place a durable outdoor mat underneath to compensate for minor imbalances while protecting your patio or deck.

For long-term stability, combine these methods based on your planter’s condition. Always check for cracks or rust before attempting repairs!
