Q.aloe vera plants
We have a couple of aloe vera plants that had done very well (even in cold weather the last couple of years) until we got the last frost in Houston a few weeks ago. I trim the damage leaves but the plants are not recovering and still look brownish and sick. I’ve transplanted a couple of the young ones but they are not picking up either. What should I do?

If the entire plant is damaged by the cold, your plant may not recover.
It does appear that some of the plant is still green.
You will need to remove the damaged and dead plant material.
