I did not graft the Cara Cara myself. I purchased the tree from a citrus nursery, and requested FD as the rootstock. Mark, I see your trees are in RootMaker containers.  I presume tha the large RM containers are bottomless, so the tree's roots grow into the ground. - Millet

Is there such a thing as a cold hardy grapefruit?  Varieties descending in order from least to most cold tolerant are citron, lime, lemon, grapefruit, orange, mandarin, kumquat.  One important factor on the amount of freeze tolerance for a treee is the age of the tree.  Young trees freeze quickly.  I think your trees will need cold protection for some time.  Citron, lime, lemon will be killed or severely damaged with temperatures in the high 20s-F. Oranges, grapefruit, mid 20s can damage even the large branches.  Mandarins and satsumas can with stand as low as low 20s-F if the trees are healthy. - Millet

Growers and homeowners can report abandoned citrus trees online using a confidential web-form at www.citrusmatters.us. Qualifying properties are located near commercial citrus groves and in an area where ACP or HLB is present. So far to date, over 400 abandoned citrus trees have been removed from residential properties in Tulare and Ventura counties.

According to the agencies that have the authority it is not GMO.   As always people love to complain, if they don't like it, simply don't buy it. - Millet

They are sold by various vendors on the Internet.  However, as you are in Florida, you might have difficulty finding an in state supplier. - Millet

Good things come to those who wait.  My New Zealand Lemonade tree that lost all of its leaves last November not only lived and grew back, but today I noticed it is once again flowering. - Millet

Lory, my first thought about your tree was the condition of the tree's root system when it was removed from the container.  Hopefully the roots were not root bound, circling around and around inside the container.  There is an old saying (and a very true saying): "Roots grow like a bullet goes", meaning a root will always continue to grow in the same direction until it hits an obstruction.  When you dug a wide hole and added all the amendments, there would be no obstruction.  The root would just continue to grow "like a bullet goes".  Second, when planting a citrus tree in the soil, dig a hole just large enough that would comfortably fit the root ball, then back fill ONLY with the dirt that was taken from the hole that was dug.  Third, a newly planted citrus tree NEEDS to be be fertilized 6 times during its first year of growth.  Beginning about 2 weeks after planting, frequent light applications of fertilizer should be made approximately every 6 weeks.  Avoid burning roots with high levels of soluble fertilizer applied all at once.  Citrus are heavy feeders, and require ample nutrition.   The purpose of the fertilizer regimen the first year is to stimulate vigorous growth of leaves and branches that will become the framework of the mature tree.  During the second year fertilize 5 times equally spaced apart, 4 times the third year, and then 3 times per year every year after that.  Lastly, if the tree's root system was indeed root bound when you planted it, it will take a lot longer for the tree to develop a good wide root system. The best to you and this tree. If I or any member on this forum can be of assistance, please feel free to ask.- Millet

The threat of the Asian Citrus Psyllid remains a huge concern for Fresno County growers. The whole county is now under quarantine in an effort to control the spread of the pest, meaning more restrictions will be in place to move citrus and other plants in and out of the area.

To make an educated reply we need a lot more information, about the care you gave this tree.  What was the fertilizer treatments that you gave this tree after you planted it?  What fertilizer did you use.  How did you plant the tree? Have you sprayed this tree with anything? Etc. - Millet

In the US897 field trial literature that I have red, it is stated that the rootstock produces dwarf trees in *comparison to other rootstocks*.  However, nowhere in the USDA literature did I ever see where they state what the USDA's definition of dwarf is. The other rootstocks that the USDA compared the US897 rootstock to must not have been Flying Dragon.  - Millet

It claims to cure everything, even viral diseases. - Millet

With a tree that is less than one year from a secure screened nursery I doubt that the tree has HLB.  It is too early too show symptoms of HLB. 
However, your tree could well have a mineral deficiency.  Further, it is quite common, even normal,  for a one year old citrus tree to drop fruit before they grow to maturity. A young Florida grown citrus trees should receive 6 light applications of fertilizer equally spaced apart during their first year.  Did you give your tree that care? - Millet
