House Plants/dieffenbachia


My dieffenbachia's were recently froze due to low furnace heat. Do I have a chance at saving them or should I be sending my husband off to the store to buy me a few new ones. (he was the one who turned the furnace down)

Hi Becky,

Whether or not your Dieffenbachia can be saved depends on the condition of the roots and that depends on just how cold it got and how long they were exposed to the cold. The foliage and stems are directly exposed to the air so they suffer more damage than the roots, which are at least partially insulated by the pot and soil.

Trim off any damaged foliage as that will not recover. Keep the plant warm. Reduce the watering and patiently wait for a few weeks to see if any new growth emerges. I know it is frustrating, but there is nothing more you can do.

I have written articles on cold damage and on Dieffenbachia care that I will email for free to you (or anyone else) who emails a request to me at
