slight yellowing of Junipers needles
my squamatas needles have slightly yellowed. the new growth seems healthy and it is backbudding like crazy since the hard prune.
could it be a fert issue? currently using blood and bone and powerfeed.

Re: slight yellowing of Junipers needles
To me and although very hard to diagnose from a pic, this looks pest related. Perhaps scale or spider mite, usually requiring repeat treatment. At least, that has been the issue when my Junis have looked like that.

Re: slight yellowing of Junipers needles
Looks like it's dieing from the inside of the branches and then moving out to the tips?
Have you repotted recently? Could it be damage to the roots from excess fert?
May be worthwhile pulling it out of the pot without disturbing the tree and checking the roots if you're able to.
I have never had this issue myself, simply an idea.
Hope your tree survives!

Re: slight yellowing of Junipers needles

Re: slight yellowing of Junipers needles
You have pruned back quite hard by the sound of it. How much of the affected foliage is old?
Even evergreen foliage has a use by date. After 2-3 years the needles are not functioning properly and the tree will drop them. That's just how it works. If you have pruned back leaving nearly all old foliage then most of what is left will soon go yellow and drop. The fact that you have plenty of new healthy shoots is a positive sign.
Don't discount Nate's diagnosis. We have seen plenty of yellowing juniper Needles that are the result of pests so check carefully for mites and scale. if in any doubt, a pesticide will not hurt the tree even if there are no pests there.

Re: slight yellowing of Junipers needles
I think it’s lack of water penetrating the right roots. Maybe even trimming the roots that marry up to the dying foliage.
The green buds show it’s still kicking.

Re: slight yellowing of Junipers needles
The word "misting" always scares me.
Make sure to water the ENTIRE pot with water getting to every surface area of the soil.
Even submerging a pot until all the bubbles stop and removing a totally saturated pot is ok from time to time.
Then ideally you shouldn't water again until the soil is near to dry - Junipers prefer not to be moist all the time.

One of the fabulous things about growing bonsai is as you get old and decrepit your trees get old and beautiful

Re: slight yellowing of Junipers needles
Let me know what you think....
ACTION PLAN
-remove pot carefully, inspect roots for signs of distress/pests/rotting.
-saturate soil using a bucket to soak in mix of water/seasol.
-spray foliage with Confidor
-Continue to mist foliage and water when necessary.
-continue to fertilise using blood and bone and powerfeed
-allow to dry out between waterings.

Re: slight yellowing of Junipers needles
not that i think its an issue but looks like there iss some dynamic lifter on top of your soil too... maybe hold of on the feeding for a couple of weeks though if your going to be doing any root work. just seasol for now.
Edit: also just another thought, are you wires maybe too tight at the junction from branch to trunk?.... ive only managed to kill one juniper so far and i came to the conclusion that that was the issue.

Re: slight yellowing of Junipers needles
the wires are 2 weeks old, and loose enough as to not restrict

Re: slight yellowing of Junipers needles
i followed my "action plan," although i wasnt able to remove the tree from the pot without losing most of the soil so i removed that step.
