Mike T, your correct when you wrote "grapefruit is diminishing", as is many citrus varieties, due to Citrus Greening. Florida production is only a shell of what it used to be, as Greening disease continually takes its toll. Now the disease is in Georgia, Louisiana, Texas, Mexico, and now showing up in California. BUT --- I got my tree, and it is growing in Colorado where it is impossible for the psyllid to live.
