Cold Shock (Yellow Leaves)

Were the plants, especially potted plants subjected to a sudden drop of temperature such as being near a window on a cold night or a power outage?  The plant may yellow some lower leaves and drop them to conserve energy for what appears to be a "crisis.

First things first....get the plant to a stable environment with a room temperature within the recommended range of the plant.  Second, re-plant to a larger pot if additional temperature drops are expected in the future.  The additional capacity of soil will help insulate the plant and reduce the amount of shock during the cool-down periods.

Plants generally recover quite easily from unexpected cold shocks. Give it a couple weeks to sprout additional leaves or to halt any yellowing that may remain present.


  1. Mister H, what is the best way to contact you? Or, you could get in touch with me at Want to talk with you about a few things re: hydroponics and products

  2. Thank you for the post. I understand a little better now how to take care of my plants. I am glad that I now know to have my plants at room temperature at first.
