You should be very happy with yourself... Nice job

Thank you for the feedback.

The scare is large but is slowly healing over. I suspect that if I had used cut paste the healing would be more advanced.

Lovely tree, you must be happy with the progress!

Nice tree, how is the taper developing? By the look of it, its going to be a stunning tree in a few more years.

Thanks,

The taper is developing well. After talking to Grant on the quicker repair Technics for the cuts, I will be busy re-doing all my deciduous trees which have the larger cuts. One of these cuts is about 100mm on a Japanese Maple I have had since 1999.
Also,as you can see the pot is a mica pot and not really suitable for the tree so I will be looking for a new pot for it this winter .

Peter

Quicker healing on large deciduous cuts? I'm all ears!
Please elaborate Peter.

Hi Scott,

This is an extract from an article by Grant.

DOUBLE SEALING
At the National Collection in Canberra the curators have been using
double sealing on large cuts and getting far faster healing. When the cut
is made the tube sealant is thinly applied. When that is completely dry a
layer of the putty sealant is placed over the wound. [The putty sealant
comes with 2 lid colours: Green for conifers and white for deciduous and
evergreen]

Regards,

Peter

I have read 2 articles recently talking about how cut paste is not just useless, but harmful to the tree's own healing. I remembered Grant mentioning about double sealing and was going to look it up when you posted this. So for anyone interested here is a link to the thread where its discussed.

I also found links to discussion on AusBonsai about the 2 articles I read Here and here if anyone is interested.

In one Shibui puts it well with the way I was thinking, correct pruning of tree branches in parks, gardens, etc. should leave a collar for fast healing. We don't do this in Bonsai as we are trying to leave no sign of the scar.

You should probably leave a collar on all plants, initially at least, to allow the tree time to reorganise itself after the cut and not dry out back into the trunk or branch. After 6 months or more the cells will be aligned with the new flow direction of nutrients and then you can reduce or remove the collar, then double seal to speed up the healing. Conifers should/could be left with a permanent or long term jin.. Allowing some time before you reduce the collar will save you healing time in the longer term

I think double sealing is great and have had no problems here in Canberra; can't speak for elsewhere with much higher humidity combined with heat etc. I have been amazed how quickly some trees have healed. I do fertilise well and leave plenty of foliage and branches on trees; so that would also help speed up the healing process.

As usual; don't just take someones word or the latest article as gospel. Experiment and use the technique that works best for you in your climate.
