Good drainage saves plants from what?
Answer and explanation
Correct answer: From waterlogging around the roots
Good drainage allows excess water to move out of the soil and prevents waterlogging around the roots. In waterlogged soil, roots receive too little oxygen and may rot. Protection from excessive sunlight is provided by shade or cover, not by drainage. Exam tip: link drainage with air availability for roots and prevention of waterlogging.
