Thanks. I will keep that in mind. I sometimes go down there to San Diego and have visited various popular nurseries.

I think that the TreeSource citrus nursery has good enough sized rootstocks for most of my needs. TreeSource also sells seeds of citrus rootstocks. And they sell grafted citrus liners at very low price.

Here's their website:

And here's the pricing of their citrus products:

But to everyone, although they have cheap source, be forewarned that they primarily cater to wholesale but would entertain retail orders from the excess in their inventory, and the shipping can take a long time because they batch it out with the commercial shipments that only occassionally visit their facilities.

So what I do, I order with enough lead time, then keep the plants potted. By the time I need to do grafting demo for various groups, they are conditioned and ready. Sometimes, 1 to 6 months lead time is needed.
