Grafting citrus fruits
« on: July 15, 2021, 11:15:53 AM »
Hi,
I am new to citrus... trying to learn as much as I can.

I live in Panama City, Panama.  Here in Panama most citrus trees are grafted on "flying dragon" rootstock, probably most commercial growers do.  Some are grafted onto other things.  HLB has become this year a problem throughout Panama.  The first cases appeared in 2017, but this past year it has spread.  Panama is small, so that didn't help.

What I wanted to ask.  I have read that some people do a double graft (I don't know how it is called).  They graft the citrus tree onto a lemon and then the lemon onto a sour orange for example.  So there is an intermediate plant.

Wow... This blew my mind!  This is very interesting.... Why is this done?  Where can I learn more about this?

Inter stem is used to graft roots of choice to an incompatible scion using a center piece compatible to both.  I am grafting Poncirus trifoliata to sour orange and will graft a Meiwa kumquat to the poncirus trifoliata.  Sour orange is highly susceptible to Citrus tristeza virus and die in a year.  Cincinnati, Ohio is free of
tristeza, HLB, and ACP.

Makes sense.  Thanks for the information.

Are there any rootstocks that are resistant to HLB?

Some people also multi graft varieties onto one rootstock, or onto an existing variety, mainly to get different fruit from one tree in small spaces.
