5-Step Defense Protocol
- Use volcanic rock base layer (2-3cm depth)
- Apply marine-grade wax every 90 days
- Install stainless steel flowerpot thermal pads in winter
- Rotate 45° weekly for even sun exposure
- Deep-clean with citric acid monthly
⚠️ Critical Mistake Alert!
Never use table salt for ice removal – it creates micro-cracks. Instead, try crushed walnut shells as eco-friendly traction material.
Seasonal Maintenance Checklist
- ☑️ Spring: Check weld seams for salt residue
- ☑️ Summer: Apply UV-protective coating
- ☑️ Fall: Clear leaf acid buildup
- ☑️ Winter: Insulate bottom with cork mat
