Localised juniper sickness

Hello all

I have a juniper in the cascade style.

I had a friend water it while I was away for 6 weeks. While away one of the branch layers died. The edge of another has also died. The rest of the tree, however, is in good health. I have looked carefully over the tree and cannot see any obvious bugs or fungus on it. When I moved it I did notice some dust come out of the needles - I am not sure, but it may have been white.

I've just sprayed it with some Confidor. Does anyone have any other suggestions to limit further damage?

Also, is there any chance the dead branch layer will get new growth on it? (Or must I accept it's gone and try to salvage a jin out of it?! )

Any thoughts would be much appreciated.

Cheers

Oscar

Hi Oscar,maybe removing the wire now to have a good look for boring pests and/or where the wire is wound for ring barking or splitting as it looks pretty well wound especially where the branch meets the cascading trunk (collar).Just some ideas for you,very difficult from a pic of course.

Hi Oscar

How long has it been in the pot?

If you could go in and add the area or country where you live also helps with advise.

Many thanks Anthony - will do.

Thanks JC.

I'm in Sydney.

The plant has been in the pot for 3 years. I have root pruned it annually since then. I last did so in June 2016. The roots still had plenty of room in the pot and little pruning was necessary.

Hi Oscar

Okie it wouldn't hurt to remove it from the pot to make sure that there isn't anything eating the roots, just to make sure.

Hi Oscar. You might have noticed that both Anthony and JC have a little house under their avatars. If you rest your cursor on it, it will show you where they are. Example: JC is in Port Macquarie. Mine says I'm in Fraser Coast Queensland. If you go to your profile, you can put in Sydney, and it will then show up a little house under your avatar. When someone puts their cursor up, it will show them that you are in Sydney. By doing this, it can give them the opportunity to offer you information specifically for your location. Please don't enter address, suburb, phone numbers or email addresses.

Hi Oscar
Did you resolve that problem

Yes and no, Adam.

The tree is for the most part healthy, as are all of my junipers.

However, that branch was quite dead and so has been removed. Another small branch on that tree and on another tree suffered the same fate.

I'm still at a loss as to the cause. I checked the roots and the tree quite thoroughly for any pests and could not find any.

Hi Oscar,

In the photo, I saw your juniper was placed next to the aircon which blows out hot air when in use. I think this could be the reason.
