Seal Wound On Trunk Chop?

Carl_Bergstrom

Creative,

My personal experience is that the green goo gets inextrictably bound to the wound site. When the tree tries to heal over, it gets all mucked up in the green goo. I have some horrible scars on a kiyohime maple, a shimpaku, a hornbeam, and a cedar (now deceased) to show for it.

By contrast, the black putty forms a seal that the growing scar tissue can push away from below, but nonetheless keeps the wound site from drying out and thus prevents the cambium that will grow over the wound from shrinking away from the underlying wood. I've had much better results with this, on the very same trees.

I asked my teacher about this whole matter. His response was simple. He took the tube of green goo and threw it in the trash.

Best regards,
Carl

ack, I used the green goo. Looks like Im going to have to pick up some black sealer then. I pondered this a bit and just gooed it anyways. Good info thanks.

I use the black sealer, but something that was new to me was when I had my workshop with Kenji he insisted on using this pinkish orange wound sealer from a tube. It had a rather watery consistency that he rubbed onto the cut. From what I could gather it penetrated the wound rather quickly to seal it up. I was then told to put regular wound sealer on top of it.

Anyone have experience with this?

Dustin, I'd definitely seal any cut i make on a tree. It is good for the trees health because it prevents any diseases from entering the wound and getting the tree sick as well as help heal it. So it cant really hurt, unless its the green goo from what ive heard

ANd then, there's Nick Lenz's recomnedation to use (generic) Preparation H on japanes maples... NOT tridents!

Is the black putty the "callus-mate wound dressing" on Treebay?

I've been using the green stuff (Kiyonal Grafting & Pruning Compound)... I guess I know why the wounds haven't healed too well.

Thanks.

I haven't tried that substance on Treebay.

Here's the green stuff that I don't like :

Carl,

When I visited the site for cut paste that you provided I read the following:

"When making larger cuts on tree trunks and branches it is advisable to seal these cuts with something which will prevent the wound from drying out and protect it against invading insect or fungal damage"

This raises a question in my mind of exactly how large is large enough to require cut paste. I would assume that one wouldn't apply it after maintenance pruning on new shoots, so what is a reasonable guideline and should it vary in respect to the tree's size?

Any insight would be appreciated.

Mark,

I don't think there's a general rule here. As with everything in bonsai, it depends. It depends on the size of the cut as you note, but it also depends on the species of the tree, the season that you did the cut, the strength of the tree, the location of the cut on the tree, the time since repotting, the availability of shoots above and below the cut to promote healing, and so on and so forth.

That said, to give you a rough sense of the range I'm discussing, I rarely seal cuts less than 1/2 cm in diameter and I almost always seal cuts over 2 cm in diameter.

Best regards,
Carl
