Why air layer? Just for practice?

But yes, I would wait until growth is rounded and not angular.

Steph your Shiranui seedling looks fantastic!!!! There are very many good examples of air layering on YouTube. I decided to give it a whirl this spring early June. The funny thing I also tried this on my Shiranui because I was worried I was going to loose it . Spring is normally the best time so if your going to try I would do so very soon . It usually takes up to 6 weeks to root . Winter is a no no to try I've heard . If your going to go ahead with the air layering I would support the branch to that stake because of the weight .

As you can see I did that with mine . Good luck Steph.

Thank you for the advice! I am mostly wanting to prune to make an extra plant since that branch is pretty low and there are other branches also forming on the opposite branch that are growing in the same direction. I may end up leaving it for now since that branch is pretty thin and I don't feel comfortable slicing into it just yet. Maybe I'll have to practice first on my satsuma that has extra branches to spare.

Congrats on your Shiranui!!!

I wish i could offer citrus air layering advice. My success is limited and has varied by type. i.e. citrumelo - fail -

Flying Dragon - success.
