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?
