Junipers new growth
Hi All,
I was wondering how to tell when a juniper had finished its flush and able to be worked on. I have some Chinese and Japanese junipers that obviously have different appearance and structure and I’m unsure exactly what to look for.
I appreciate this is likely a dumb question,
Thanks,
Steve

Re: Junipers new growth
No questions are dumb.
Just wondering why a juniper must be past first flush to be worked on? When did that become a rule?

Energy. Once past “first flush” or “hardened off” then the foliage is creating energy and has gotten the tree pumping.
My old olders and wizers tell me that juniper keeps its energy in the foliage but elms keep it in the roots. So one cannot remove all the foliage like one might with an elm. Rather one needs that foliage to be thriving before thinning it out (and hopefully getting some back budding)

Re: Junipers new growth
Leaves, particularly getting energy to the parts I want to develop, as well as reducing the branch length with backbudding hopefully

Re: Junipers new growth
Do you have photographs?
My approach is heavy feeding, full sun, regular thinning of foliage to improve air flow and light and then keeping crotch growth.

This is an example of a young Chinese juniper.

Re: Junipers new growth
It is definitely not good to remove all foliage from junipers but that does not mean they store energy in foliage. All trees store resources in all parts of the plant - roots, trunk, branches and foliage. It is meaningless and quite untrue to say certain plants store energy in different parts. Those same olders and wisers will also say that pines store energy in the roots but we still cannot chop a pine to bare wood.
Healthy trees will certainly bud much better than weak ones but that is also nothing to do with where energy may or may not be stored. Every species will respond to any pruning better when it is fit and healthy.
I trimmed and wired several shimpaku yesterday even though they are in full growth mode. Experience shows they will have no problem as a result. I prune junipers whenever I have a tree that needs it and the time to do it and certainly don't have a yard full of dead trees as a result.
having said that there are a few caveats with junipers in particular:

having said that there are a few caveats with junipers in particular:
- Roots recover slowly so best not to do much pruning for at least a few months after root pruning and even longer after severe root pruning.
- Severe bending during the growing period spring - mid summer often results in dead branches so best to defer shaping until less vigorous growth. Usually after mid summer is OK.
- Pruning when there's lots of juvenile foliage will likely trigger more juvenile foliage. The pic shows lots of spiky needle type juvenile foliage so I'd agree with Treeman that it would be best to stay away from this one for a year or so until growth settles down to adult scale foliage.

Re: Junipers new growth
Juvenile growth is really what I am asking about I think, not the hardening concept or whatever it’s called.
I will do some more research, but I think I get the idea of it. Thank you
