Q.Pony Tail Palms located outside
I have 4 pony tail palms planted in pots and all are located outside in my yard. I have had these plants for many years. This past winter, they all froze for the first time. I left them alone thinking that they may come back and sure enough, each plant has several pups growing from the side of the trunk. Will they continue to grow like this or do I need to remove each pup from the plants and transplant each one separately? Also, the trunk on 2 of them is somewhat mushy. Does that mean that the trunk is dead and the pups are coming up from the root system? One of the plants has 5 pups on it. Thank you for any help you can give me.
It would seem that the pups are trying to replace the mother plant. This is common when the main plant suffers damage. You can either leave them, or transplant them out. This article will give you more information: https://www.gardeningknowhow.com/houseplants/ponytail-palm/ponytail-palm-care.htm
