Saving a Ponytail Palm with frostbite
My potted ponytail palm, I am assuming, received frostbite from a bitter cold week of extremely cold weather one week even though I put it in my greenhouse. The temps reached down to 20 degrees for a few of those days. Now the "3 tails" on that palm wilted and drooped over. I cut those 3 trails off and brought the plant to my covered back porch, which has a warmer temp of approximately 10-15 degrees. Have I done the right thing and is there anything else I can do to aide in its recovery? The base of the palm is still showing signs of being strong and sturdy.
Keep the plant in a warm area and avoid any accidental exposure to cold again.
Cold damage can take days or even weeks to appear.
