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?

I have done a little research and see that seedlings can work (true to
type) but take a long time to fruit and may be not be hardy without
grafting them to rootstock.

I also see that budding the original tree onto rootstock will produce
fruit much sooner (the bud remembers it's age). Will this produce a
tree that is allready old and may not live long? How long would an
old bud placed on a young root be expected to live?

Any other methods I should consider?

Thanks in advance for any help,
Michael
