Question
I have had my ponytail palm outdoors throughout the summer. Now that it is fall I have placed it inside, in front of my sliding glass door that faces the east. It has been green all summer but now that I have moved it indoors it has began yellowing. Is there anything that I can do to green up the leaves?

Answer
Stephen,

Once the leaves turn yellow you can't get them to turn green again. The thing is to figure out what made them turn yellow to begin with.
Are their drapes onn the sliding glass door? How big is the plant?
What is the diameter of the base of the plant and the diameter of the pot?
How often have you watered it since bringing it indoors? Have you fertilized it?
Was anything sprayed on your lawn or anywhere near the plant before it was brought in?
Answer all of my questions and I will try to help you figure it out.
