What is a sign of root rot in potted plants?

• A. White, firm roots
• B. Roots with a sweet odor
• C. Roots actively growing in soil
• D. Brown, mushy roots with a foul odor

Answer: (D)

Root rot shows up in the roots as brown, mushy tissue that often gives off a foul odor. This contrasts with healthy roots, which are white, firm, and smell neutral. Overwatering and poor drainage create conditions where fungi and bacteria attack the roots, causing them to decay. So when you see brown, mushy roots with a foul smell, that’s a clear sign the plant is dealing with root rot. If this occurs, you’d trim away the damaged roots, repot in fresh, sterile mix, improve drainage, and adjust watering to avoid soggy soil. The other options point to healthy or non-rot conditions (white, firm roots; an odor that’s not foul; roots actively growing).
