Title: pulling vs cutting needles on JBP
Post by: Dirk on September 13, 2012, 04:37 PM
Hi,

There seems to be a big difference between pulling old or new needles and cutting new or old needles on JBP.
I believe to recall that in early winter old needles were cut with scissors and new needles were pulled out.

I may be wrong though. And I can't see why?

When we cut old needles, just above the sheds, can we still have needlebuds developping here? And do want to have needlebuds developping on old wood? With pulling needles there's no chance of preserving the needlebuds?
Adventitious buds only appear on the internodes, were the extension of a branch took place?

On JWP cutting needles is done to prevent the bark from damage. This is different?

Who can explain this in a few lines?

Dick

I always pluck with fingers or tweezers and i only cut needles where i am trying to prevent ripping off a small bud.

Cutting is to reduce the risk of damage and bleeding to the branch.

JBP are vigorous enough to back bud easily.  Adventitious buds are better to work with than needle buds.  Since JBP are more vigorous and will readily pop adventitious buds we don't need needle buds.

Also, I believe the "trauma" of pulling needles also works to induce adventitious budding.

Increased light and air to the interior doesn't hurt.

Thanks to all, more pieces of the puzzle fitting into place.
Still going cautiously.

I cut them off personally, just easier for me and either method will work, if done correctly.  ;)

Yes, early in development cutting them off can be fine, though you don't get the practice of cleanly pulling the needles and sheath that you will need if you ever want to have clean branches on well developed or show trees. The japanese professionals (who primarily do JBP) pull the needles. And they do everything possible to speed things up so they can get as many trees done as they can. May be just to leave a clean, well done tree, for the customer.

Makes sense John.  Cutting is def. not as clean as pulling them.

Thanks for your comments!

Still one small question:
Does JBP backbud on a branch with no needles, in the part of the branch where needles where removed, or is it only budding on the spots where there was extension.

JBP can push buds wherever there is bud information.  JBP will pretty reliably push buds at the base of previous buds/extensions.

To add to Matsu's post, the part of the twig that was the "neck" has no bud "information".  The "neck" being the part of the stem between the base of the new candle and the first set of needles.
