Hi all 
For the ones who are used to air layering.
I'm making an air layer for a friend. This is what it looks like now and around 1 one month before severing.
It is between 1/2 inche and 5/8 thick 18 inches long.
Should I cut the tip bud while attached to mammy to force laterals and figlets or should I let it be the way it is now.
If someone did it before or have an idea on the subject your opinion is greatly appreciated.
Thank you for the feedback.

I'm only interrested in roots at this stage. Just separate the new plant from mother tree when the time is right.

Thank you Sas, it makes sense.

I would keep the air layer on the mother tree for another week or two to develop more roots before separating.

Thanks Leon
I plan to separate it around the 19 of july.
Today makes 29 days that I started the air layer, on the 19 next month it will have 2 months rooting.
I think by then it will have the roots long and hardened enough to separate without braking them .

I agree with Leon than more time is needed.  You should wait until you have a dense, tough root ball.

I've done only roughly two dozen air layers, but it takes 6-8 weeks.  Also, based on my observations, the rooting seems faster when temperatures are high.  For example, this year's crop was going very slowly with temps 45-65 F, then last week is was 80-90 F and the rooting has exploded.

FWIW, I usually prune lightly when potting the air layer.  That reduces the burden on the new roots and reduces the risk that leaves wilt and drop.  But how much depends on the relative size of the root ball and the tree size.  Keep the potted tree in the shade for a couple weeks until rooting is solid, water well during this period, and sprinkle the foliage from time to time to help reduce desiccation.

Thanks Joe
I'll follow the directions and make sure the root ball is dense before separating it .
I would hate to ship it to my friend after all that time waiting just to know later that it died.
Will give it the time it needs just to be on the safe side.

I didn't realize that you are shipping it.  In that case, I would pot it in a smallish container, prune it fairly hard, wrap it up tight, then send it to the friend.  He/she can keep it in shade, etc. with the thought of up-potting it fairly quickly (2-3 weeks).

Here is a link to a post that I made regarding the air layer process. It's best to remove some leaves from the air layer after you separate it from the mother tree, especially if the root ball is underdeveloped. (You can also remove some leaves when you start the airlayer while it is on the mother tree). I remove most of the lower larger leaves and leave perhaps 3 or 4 smaller ones at the tip of the airlayer.

I'will ship it with the container Joe.
Leon, it is rooting in a snap cover container like you have in your link, as it is 1 1/2 inch flat it's easier to ship without disturbing the root mass.I got the idea from your post when i made the air layer.
Thank you all for the good tips.
Very appreciated 

I think you'll probably lose all leaves during shipping, except maybe those still emerging.  But that's OK.  Potted and watered, the tree will grow quickly.  

While it would add shipping weight, I'd try to water the rooting medium before shipping.  Maybe best a few hours before you cut the air layer from the parent tree.  Given the delay between separation and potting, I think you want the air layer to be well hydrated before you separate it from the parent.  I'm assuming that the container drains OK, so you can water without leaving the roots in a puddle while shipped.

Yes the container drains well as the bottom hole is low. I even drilled a straw hole on top to humidiffy the medium, the roots look happy so I'm I.
As the snapping container is 1 1/2 inches flat I will ship it with the air layer, that way, no drying or disturbance to the roots while in circulation, it should be Ok.
