Question

What causes yellowing in leaves?

  1. Nutrient deficiencies
  2. Overwatering
  3. Underwatering
  4. All of the above

hintHint:

Overwatering, underwatering, mineral deficiency, and temperature stress cause the yellowing of leaves.

The correct answer is: All of the above


    • Water issues in plants, either too much or too little are, the leading reason behind yellow leaves.
    • In overly wet soil, roots can't breathe. They suffocate, shut down and stop delivering the water and nutrients plants need.
    • Underwatering, or drought, has a similar effect.
