I know you're a long distance from Lee county, but I think this is something we all need to know, just in case. I got this email a week or so ago.
URGENT NOTICE
Dear Growers,
The Florida Department of Agriculture and Consumer Services has put an immediate quarantine in place for all of Lee County due to the presence of a major pest of lychee, Aceria litchii, known as lychee erinose mite. This pest has been found in several locations in Lee County including in lychee groves on Pine Island, and on residential properties and plant nurseries in other areas of the county.
To prevent the further spread of this major pest, the department is prohibiting the movement of lychee fruit or plant parts (trees, leaves or stems) out of the county.
There is more to this letter, but you get the gist. I had just bought one a couple of months ago, so I'm watching it carefully, I'm one county south.
