Overwatering can lead to which outcome in plants?

• A. Stems become stronger
• B. Root rot is discouraged
• C. Leaves become larger
• D. Root rot occurs

Answer: (D)

Overwatering deprives plant roots of the air they need. When soil stays too wet, it becomes waterlogged and the oxygen in the root zone drops, causing roots to suffocate. Healthy roots take up water and nutrients, but as they slow down and begin to die from the lack of oxygen, they can’t perform this function. This decay often spreads because fungi and other rot-causing organisms thrive in consistently moist conditions, leading to root rot.

As the roots deteriorate, the plant shows stress symptoms like wilting despite frequent watering, yellowing or dull leaves, slow growth, and eventually dieback if the problem isn’t corrected. You might also notice brown, mushy roots and a sour or rotten smell when you check the root system.

So the outcome of overwatering is root rot, not stronger stems, not larger leaves, and not a reduced tendency for rot.
