Shimpaku fusing?

[phongtien1996]

Hi,

I just saw this method from a Japanese guy, have anyone tried this before?
Does this work on larger cuttings as well?
I can see that he also makes some wounds before tying them together, is this necessary as I'm afraid it will weaken the cuttings...

type in "clumps" in search box... plenty of reading available... never tried on juniper but quite common project on deciduous trees...

All species will fuse if held together long enough.
Junipers will fuse without cutting the bark but it will take much longer and can be hit and miss. The trunks need to be tied tight for a year or more and the ties begin to cut in and mark the trunk. Removing some bark at the contact point makes it more certain and speeds up the process to just a few months.
Ties right around the trunk like shown will cut off circulation and can kill part or all of the trunk if left too long so please check regularly if you choose to follow this tie method.

It will work with any sized trunks but thicker trunks are much harder to bend if you want some shape in the trunk.

Thanks so much, so basically it is the same as approach graft.
Will try with my cuttings.

Because it IS an approach graft . Works best on Deciduous trees. Will take a lot longer for conifers in a container

Which YouTube channel did you find this on? currently twisting young itoigawas into monstrous shapes to see how they grow long term

if you wrapped the seedlings together with raffia instead of zip ties before bending it might help a lot.

Raffia certainly takes away the problem of cutting off circulation but doesn't prevent marking the trunk.
I've had occasion where the trunks swelled below and above the wrap- because it could not swell under the wrap. Neither Inverse taper (swelling above raffia wrap) or abrupt changes in trunk thickness (swelling below raffia wrap) look good on bonsai trunks.
I've also unwrapped bent trunks to discover impression of raffia spiralling up the bark.

Maybe I left the wraps on too long but the occasions I used it to fuse trunk splits, the splits still had not healed properly and the swollen areas were already bad enough. Maybe remove and re-wrap?
