      Question

      What does the process of "hardening off" involve?

      A Gradually exposing seedlings to outdoor weather Correct Answer Incorrect Answer
      B Stopping all watering to make the plant "tough" Correct Answer Incorrect Answer
      C Adding heavy fertilizer to strengthen the stem Correct Answer Incorrect Answer
      D Wrapping plants in plastic to keep them warm Correct Answer Incorrect Answer

      Solution

      Plants grown indoors are "soft." Hardening off prepares them for real-world wind and sun, preventing "transplant shock" when they are moved to the field.
