How soon can I air layer a newly planted bareroot tree?

Yesterday, I bought a bareroot apricot, about seven feet tall, trunk greater than 1".

I bought it locally, and got it in the ground quickly.

Anyway, I want to cut off the central leader, so I figure I'll air layer it and get a free tree.

I'm worried that I might over-stress the tree, because I literally just planted it yesterday. However, airlayering doesn't involve me cutting off the central leader instantly - I'd cut it off in four or five months, for a later-summer/early-fall planting.

Does air layering itself, prior to cutting off the branch (which happens way later), stress trees?

Should I wait a week? Three weeks? Ten?

I'm a tad too eager to try air-layering, so I went ahead and did it anyway.

I probably would wait until the roots started to grow & absorb nutrients, and the tree began pushing new growth, before I did the air layer.
Although, if it was potted instead of bare root, I would consider doing it before then.
While doing it sooner is unlikely to kill the tree, my thought is the layer would be more likely to fail, and the layered branch die, due to the bare root tree not having enough energy reserves to, both, establish a root system & push foliage, as well as push roots at the layered site.
Of course, I could be totally wrong, and the injury at the layered site could stimulate the trees survival mechanisms, causing it to want to propagate to ensure survival and having the layer take.

Let us know how it works out!

That's kinda what I was figuring - I definitely should have waited several weeks, or even a month.

However, I was doing three other air layers (on established trees), and I was impatient, so I did it anyway. =)

I figure the worst that would happen is the branch itself would die, which is no problem, because even if I didn't air-layer, I'd still want to cut that branch off.

We'll see how it goes!
