Hi,

I have a very old grapefruit tree with great tasting fruit. Really the
best grapefruit I have ever had. It is white, large, and very sweet.
I don't know the specific cultivar or rootstock. It is in S. Florida.
How can I find out?

The tree is 30-35 years old and looks like it is declining. There is
some bark damage around the trunk. It is about 25.' tall How can I
start a new tree with the same traits?

Cloning is called for. Air layering is often recommended for citrus trees.
