Questions: One of my Queen Palms has died as a result of Ganoderma. It has been recommended to have the tree removed in its entirety, including the roots. Do you have any idea how deep the roots on this tree might go? The tree is a good 15 years old and stands about 30 feet tall.
I also have 2 other Queen Palms in my yard. Should I be concerned? Is there anything we can do to proactively insure their continued livelihood? Also, can a plan another Queen Palm in its place? Thank you.
Answer: Ganoderma Root is a very dangerous disease that is caused by Ganoderma zonatu fungus. There is no treatment against it. You just need to destroy the tree and the root system. Roots of the palm usually don’t spread farther than the palm’s fronds. The fungus can survive in the soil, so I would not recommend planting another palm in its place. ~Susan Brian
