My first plumerias...do I trim off the old roots?
A dear elderly lady gave me two plants last year that were in bloom. Planted them in the yard and they grew/bloomed happily. When first freeze was near I was told to just pull them out of the ground and put the plants in the garage.
The old roots seem dead, stalks are 3-4' tall. Do I simply plant them in the yard & water with root stimult or ? TIA
