Idk if it matters but I have a few species.

The one pictured is a procumbens. I also have 2 procumbens nana and 1 chinensis. The procumbens nana where the first who started to die, they are both in big pots growing pretty much wild. Then shortly after the procumbens (pictured). A few weeks after, the chinensis started dying, that's when I realized something odd was going on.

I know what you mean. My juniper - the one that is supposed to go to an exhibition - is having a very similar issue: tips dying, and then it spreads further down the branch. I have lost some minor branches. On some parts, where the tips have died off, new buds have appeared - but not everywhere. It is likely that I will loose more branches, and looking at the overall colour of the tree, that is now yellowish-green, in stead of bluish green, if is very improbable that it is going to make it to the exhibition. If it survives, I will have far less branches, and maybe not enough to build it up again.

Painful, very painful. I have been working on this tree since 2001 and it is my best bonsai - actually the only one that really is beyond the pre-bonsai stage.
I guess that is life. I am in a less fortunate life in my life where I am loosing a lot - and this seems to be part of it. Nothing I can do about it and grieving is pointless. Better look to the future.

Symptoms of my tree:
Tips dying. As explained before by LB I think, the tips are essential for the tree. Yellowing of the lower needles, and next them dying off as well, slowly progressing to the base of the branch, until no needles are left and the branch is lost.

The tree turned purple last autumn - but it turned green again a few weeks later.

Possible causes:
- Scale. I have noticed it was infected, but this seems minor. I have treated it but this hasn't helped.
- Soil. The soil was compact and not draining too well. I moved it to a larger pot, poked holes in the soil to improve drainage. This was a year ago. It seemed to help, but aparently not.
- Sunburn. The pot getting overheated, causing the roots to get damaged.

I have repotted again this year. I noticed nothing strange in the soil, and the soil did not appear to be as compact as I expected.

Actually, I still do not know what the problem is. Nothing has helped so far. Guess I'm not being very helpful either... sorry.

Auk, did you peel the bark of your juniper? Or is it flacky? You can have aphids & scale below the layer of barkflakes. I almost lost a juniper that way, with very similar symptoms. It had black aphids in cracks and below the branches, all the way into the soiil. I spent a year getting it back to health, lost 90% of the foliage. Today I noticed the aphids are back again. This weekend the strongest poison I can get will be drenching the tree and roots. It is growing for the first time in 3 years...

This is what?s killing junipers of my local fellow bonsai enthusiast most often I was told:



Check for any tiny holes in the bark.

Yes, long time ago. The juniper has a nice red bark under the older flaky bark, so I have stripped it off. There is no sign of anything that should not be there.
I was preparing the tree for the exhibition, so I have been cleaning the bark too. Also, I filled the room between the roots with keto and put some moss on it - to make the base look more massive. That part is looking great now...

Some parts are forming strong new buds. Other parts are not and it is likely they will die off, if they do not start creating buds soon...
I should post a picture - but I should not be hijacking this topic, so I?l post one later, in the juniper's own thread

No holes. I have spend ages on this juniper, checking it, removing scale bugs one by one with tweezers, inspecting each needle, removing dead needles but I see nothing strange.

A fungus (blight) maybe? Seems unlikely, I have more junipers and none are affected.

That was more info for eangola, I knew you probably inspected yours with a close experienced eye Auk

Oops. Sorry, did not plan to hijack this topic. I 'm out
