Good drainage protects plants from which problem?
Answer and explanation
Correct answer: Waterlogging and root rot
Good drainage removes excess water from the soil. It prevents water from collecting around roots, maintains air spaces in the soil, and reduces root rot. Lack of air may result from waterlogging, but drainage directly prevents waterlogging and root rot. Exam tip: link drainage with oxygen around roots and prevention of root decay.
