Mugo Pine Jin Issue

BonsaiSteve1

I have a Mugo pine I did some jin on about 3 weeks ago. I have a couple of questions on “jin-ing.” Since I did it, the tree has poured sticky sap, or pine pitch as I call it, out the branch and around it. This has slowed down, but there is a significant amount on the branch still.

Is this a normal process that will stop once the branch has completely died?

Is there a way of removing the pitch, or will it eventually lose its stickiness and go away?

The jin-ing process is to cut the cambium so the branch dies, correct? Do I need to put some of the lime-sulfur jin seal on the branches? What exactly does this stuff do?

Normally, dead branches dry and break off. What keeps a jinned branch from doing this?

I am a beginner with jin and any help would be much appreciated.

This type of work would have been better to wait till fall or winter. Let it dry and calous over, then clean it up later.

Hey Steve, as the cut heals it'll stop. Let it dry out for a while, then put on the lime sulphur. The lime sulphur helps keep the jin from rotting so quickly, sometimes you use a wood hardner/ preservative if it starts to rot out. The resin in pines also helps with the rotting problems. You can do the lime sulphur in the fall, the wound should be healed up, and you can scrape off the pitch, and maybe carve the jin down if it needs it.

Heard the workshop with Nagatoshi went well, the demo after was excellant, wish I could have been there for the workshop too.
