Question
Umm...I have two more Qs (so far). One is: I heard that when you plant citrus trees from seeds they grow on their own and then produce their own fruit without pollination. Is this true? Second Q: I'm not sure about all the cutting stuff. Can you tell me more about it? Is it when you get to pieces together from two trees and they grow into one? Ho does it work?

Answer
Hi v,
Thanx for your questions.  I know that most cirtus don't require another for pollinator.  I had my Meyer lemon set fruit without a pollinator.  

As far as cuttings go.  You should find this URL very helpful in your inquiry regarding cuttings.

I hope this helps.
