Lining Metal Containers for Carnivorous Plants: Plastic or Porcelain

Portland, OR grower: antique metal wheelbarrow for VFTs. Asked if thick plastic liner works, or porcelain (like nursery tub).

Both Work

• 6-mil black plastic – excellent, inert.
• Porcelain – inert, doesn't react with peat tannins.

Drainage Setup

1. Drill holes in wheelbarrow bottom.
2. Poke aligned holes in plastic liner (use straw to align).
3. No rock layer needed unless to hold plastic.
4. Mix: 1:1 peat:pumice (less floating than perlite, porous).
