Rust-Colored Spots on Venus Flytraps: Diagnosing Water and Drainage Issues

Initial Question

Venus flytraps in a bog garden (plastic container buried, drainage holes 1.5" from top, peat/perlite, distilled/rain water, full sun, NW Ohio, temps 55-81°F) show rust-colored leaf edges and loss of red trap color. No fertilizer used. Should container have bottom drainage?

Answer

Stagnant water in the undrained lower half of the container is the likely culprit. The container acts as an undrained reservoir—water doesn't move through, causing waterlogging. Flytraps are sensitive to this. Add bottom drainage holes; water more often but soil will stay oxygenated. This differs from a pot in a tray where water circulates.
