So this was my first attemp at air layer. Started on 25th feb and i cut it today. Hopefully both trees survive.
I am not too sure what to do with the new upper part. I was thinking to create a dead trunk on the left hand side and let the top one be the new trunk.

This is 25th feb The cut In the new colander Remaining part

Hi bonsaeen , well done mate , its good to see material put to use by layering off rather than just cut off and discarding . The base should back bud quite well if not I would reduce it down to the next branch and try for a twin trunk . Wiring some good movement into the layer would be my next move .

Cheers . Alpineart

Thanks Alpine. Do you think i can repot the base twk in a couple of weeks or better to leave it for now?

Repotting is for when your trees roots have out grown the pot it's living in, so you don't really need to repot it right now. The only thing I would do is slip it into a bigger plastic pot and give it plenty of sun and fertilizer.

Are you sure it's a chinese juniper? The bark and blue needles look like a squamata.

I am retty sure its chinese juniper. I dont own squamata but ive seen it at bunnings and this one is not the same. Thanks for the tips.

Definitely not a Chinese juniper, it looks like a squamata.
Chinese junipers or shimpakus have scale foliage.

So this tree didnt back budd but i see alot of growth in existing branches. Should i cut back further?

does it usually take 6 months for air layer on juniper?
if it is done (now) in spring, will it be same duration before we start seeing roots?

Junipers are not good at growing buds on bare wood. You will often get new shoots at the base of a branch which is good for replacing long, bare branches but you should not cut back too much to force new buds on bare wood. If some shoots start, let them grow until they are strong before cutting back.
Cutting too much off a juniper can weaken it. It may even die after severe pruning.
Because they don't bud too well, Juniper branches are often wired and bent back around, down or up to fill in spaces where there is no growth. I guess that is also natural for a species that lives in really severe environment too.

The 6 months for this one was over winter when growth is slow. If you layer now you should have good roots before the end of summer but that depends on how healthy and vigorous the tree is and how well you are looking after it. Also depends a bit on the species. Some grow better than others.

Guys,

Need some urgent advise. The cutting from air layer seems like dieing on me :,( and i have no idea what to do.

My guess is that this has dried out at some stage. Probably a few weeks ago. It seems to take a while for symptoms to show on junipers and by the time it does show up it is usually too late to do anything.
I would keep watering it for another couple of months before discarding. I have seen more than one 'dead' plant come back.
