Question
I have a Howea Forsteriana.  I have noticed a cottony white substance on the new growth.  I have cleaned them off with alcohol, but am wondering if this is a fungus or pest problem?
Would I be better off just moving the palm outside?

Answer
Hi Katherine,

What you have described is mealybug. A solution of rubbing alcohol and a squirt of liquid soap is an effective treatment for mealybugs, provided you get thorough coverage of all leaf and stem surfaces. Pay particular attention to the crevices where the leaves emerge from the main stem.

Kentia palms are low to moderate light plants and do not do well outside unless they are in shade at all times. As long as you can keep yours close to a window indoors, it should be fine.

Please let me know if any of this is unclear or if you have any additional questions.

If this information has been helpful, please take the time to give me a rating and nomination.
