Cut Paste Vs Wound Sealant ?

[just.wing.it]

Can some please explain to me the difference between cut paste and wound sealant? (Other than the obvious different physical characteristics)
Is there an appropriate time for one or the other to be used? Or an appropriate type of tree, or cut ?

Good question. I am not a big user of this kind of stuff but in general have found that sealant (something gushy) seems to help better than a hardened putty.

cut ?

I posted a pic of my berberis, in lazylightenings clump Berberis thread.

On a non barked a section, the grey (top tub except I have the 500g version) worked fine.....but on a big branch cut, where there was thicker bark....I would (now) opt to do like Adair does with an azalea......first cover it with the liquidy stuff......to get in and really seal out water.....and then cover it with the grey, to water proof the water based liquidy stuff.

The "liquidy" stuff.....though I haven't used it....seems to have a consistency closer to pipe dope.....or flux.
Where the grey is almost plumbers putty.

Of course.....there are times/trees, no paste is better.
And times for both the others......

One thing I think......Vaseline is a tree killing joke.....

I used loctite GO2 glue with success on an elm that is still healing....but ficus sap makes it NOT work.....

I swear by the putty stuff....particularly on maples, azaleas, elms, Bald Cypress....I havent used the other for years. I don't really think it matters what you use as long as you are using something to keep the area around the wound from drying out.

I have had trees heal a three inch pruning scar in one season by using the putty... I'm sold!

Same here! Healed some big ole scars in one season on a tree where a similar sized wound had taken 3-5 years to heal over previously. Only ever used the putty... I know some people use both, and some use the stuff in the tube... Seems as long as you are protecting the wound it heals faster... It seems to heal over smoother as well in my experience. I have seen this to be the case especially with Maples, Azaleas, CM and most D trees... Junipers just don't like to heal over a cut area PERIOD.

The liquid just seals from water, the paste seals less, but provides a humid place for the callus to grow and has hormone in it. The one with the green lid is for evergreens, with the white it is for deciduous. The liquid we use for big cuts on roots. I've used it on branchcuts before i knew how to. Sticky thing, do not know if it works. The paste is the way to go. The snails like to eat it here so i cover it with "plastic wrap", makes it easy to model and stays soft longer. Don't forget to put some water in the pot...

So what I take from this is it's worthwhile having a ready amount of both on hand.
I had a cut paste in my basket but am now going to add the sealant too.

 

[dirk hoorelbeke]

i've used the liquid only twice on an airlayer, not sure if it is on the necessary-list.

And some folks use various outdoor wood glues. Seems this is about like soil, everyone has their 3 favorites.

I have been using the wood glue which is much cheaper and have not got any problem so far!

What hormone - IBA, NAA (auxins) or what specifically?

 

[thumblessprimate1]

Is the paste the one in the jar, while the sealant the one in the tube?
I've started using the one in the tube this year.; it smells a lot like Elmer's glue or just plain wood glue to me. I may get a jar of that stuff to try out some time.

 

[dirk hoorelbeke]

the tube is more a glue / sealant. The paste is in the pot. I've been told there is antifungus and hormones in it. But they can tell me everything. Does not taste good so might be something in it.

 

[0soyoung]

Trees have natural mechanisms to seal themselves or compartmentalize damage. The only productive thing we are doing with cut paste/sealant is preserving moisture so that the exposed cambium does not desiccate (and die back, effectively making the wound larger) before callus can form (safely within 10-15 days). Just about anything will do the job. Damp sphagnum, saran, and Elmer's glue to name a few. These pastes/sealers from Japan are just expensive convenience (but official bonsai) items.

BTW, pines are cool because they have their own built-in cut paste/sealer = resin bleed

Dude you tasted the tree wound paste? I doubt it tastes like strawberries...Why would one taste it? Surely it has a warning label... I dont have any to try....

What type of trees?!

I was doing a bit of research when I stumbled across this thread. Here is what I’ve found on the Kaneshin website explaining this

Cut paste vs sealant summary
Difference between green lid and white lid cut paste

I have to wonder, is it bad to use the brown paste with hormones on other trees, too? Why not double down and speed everything up?

Yes. The limb I BROKE while wirinig a JBP has the gluey sealant on it. It is healing nicely. The sap helped too. What I like about the sealant is that it can be worked into breaks and you can wire it tight and it heals good.

very interesting! I hadn’t heard of sealant being used to mend broken branches!

I used Gorilla Glue to repair a REALLY broken branch on an elm.
Roughed it up and painted it.
It's not even noticeable now.

Some of the requirement is probably to have an easy healing breed of TREE !!
