QuestionIs a 4" deep pot deep enough for a Darlingtonia?
AnswerDarlingtonia doesn't have very deep root systems, so 4 inches is deep enough. We've successfully grown Darlingtonia in containers that were no deeper than that. However, the real question is whether your container is wide enough. If your pot is only 4 inches across, then it'll be inadequate for an adult plant. Darlingtonia likes to spread out, so a wide container is preferable.
Good growing!
