Meyer lemon cuttings are relatively easy to root; if you have done it before with other cuttings, you will probably succeed first time. I would use the Clonex gel. Meyer lemon rooted cuttings are not very resistant if planted in the ground; but in containers they are fine. FYI, your rooted cuttings will not be dwarf; but the Meyer tends to be a smaller, bushier plant anyway.

Thanks John,

Should I use green recent growth for rooting? Or should I cut back to last years wood?

When rooting cuttings, it is important to have enough carbohydrates in the cutting to produce roots; that is mostly a matter of thickness, so if that means you have to include some of the last year growth, so be it.
