Aluminum Containers for Carnivorous Plants: Safe or Not?

A grower asks if an old aluminum roasting pan with a slotted bottom and drain pan is suitable for Sarracenia and flytraps, using 50/50 peat/perlite and RO water.

Recommendation

While aluminum probably isn't directly toxic, it's best to avoid metal containers. Peat moss contains tannic acid, which can react with metals. Stick to non-metallic pots (plastic, ceramic, glazed) for long-term safety.
