Q.After removing a diseased palm tree can we plant another palm tree right away?
Our palm tree has ganoderma, 7 is scheduled to come down. We have received conflicting information re: how long we have to wait to re-plant another tree.

It is risky to plant another palm in the same site, especially right away. It is safer to plant another type of tree.

last paragraph:
"We do not know how long you should wait before it is safe to plant another palm in a Ganoderma-infested site. We can say that the time is measured in multiple years, not months, since the fungus is probably capable of living in the soil almost indefinitely"
But if you are determined to plant another palm, you can drench the soil with a biological fungicide twice or three times this year and plant next spring. This is not a sure cure, but is the best way to attempt to suppress the disease without chemical sterilization.
