Restoration Pruning

[David Goss]

Rob,

I'm not sure, but I suppose these are the endings of radial rays, i.e. "sleeping buds", from which twigs or branches can be activated.

A photo of "spikes" on the trunk of a poplar, which was debarked by rhizomorphs of a Honey Fungus, follows.

That would have been my guess as well but wasnt willing to say it first:blushing:

Is there any way of detecting these from the bark side? if so then you could be on to a winner rob:thumbup:

Unfortunately i have not seen these on limbs but only on the trunk so it may not be exactly what your looking for unless i am wrong.

don't worry david, i'm hoping to do a lot more research yet into this type of pruning as the new BS3998:2010 doesn't have much if anything on it at all

[RobArb]

about detection, it comes down to species, but so far results are good:thumbup:

I would be interested to find out what conclusion you come to anyway, keep it up

I tried damaging and semi ring barking a mature oak 3 years ago. Going to revisit that site in a few weeks so can update you on how it responded. It's more likely that selectively thinning the upper crown would be more suitable on la trees. You can thin enough to encourage dormant bud growth the continue to prune the upper crown to favour these shoots over time. It might be that on future prune you can begin to shorten the odd branch or stem back to its final piont before the rest of the crown comes down. I think its better to pull the odd branch back rather than repeatedly shortening the same branches

Rob,

In my database, I found another photo of "spikes" on the trunk of a debarked poplar.

thanks gerrit

 

they do seem to be more in abundance on quicker growing trees, although as stated i have found them on most species (so far)

I would think these Bumps are present on ALL species, they are after all just dormant buds. some will be more obvious than others but debarked pop and syc will rip your hands to shreds with these

[RobArb]

and thats where i'm going with my mini research project

 

the dormancy, not the ripping of shreds off of arms:lol:

then do ensure you research howm many are evident in the ancients too, recording thier physiological condition at the time of observation.

 

would be usefull in restoring lapsed pollards
