Hello All,
I acuired this Ponderosa recently form someone who needed to find a new home for thier trees.
I don't think it was getting enough sun at it's previous owners, that and relatively sparse foliage has led to some very long needles.
Also there are numerous places where the bark is being forced up and off the branches.
Looks like callouses from some sort of injury. not sure if this is from an attempt at bending the branches or something from before collection.
That being said I love the trunk and bark of this tree and the nebari is great for a collected tree.
My thought was to start grafting to replace the foliage w/ JBP next spring due to the injuries/ missing bark on the branches.

Thoughts or suggestions?

The trunk has a very nice curve - but I have no idea what caused the injury or why. That said - I cannot tell whether you have green needles above the wound area. If so - let those needles branch grow stronger. I also wonder whether the tree had borers as the sawdust and pine resin combined - make that reddish color?  Perhaps the former owner cut the borer or infected area out ? The tree's needles look healthy - the yellow - light brown needles are probably the older needles that are ready to be pulled off. If the tree is larger- say bigger than 18" to 24" then the longer needles don' t look as bad as say on a smaller 12" tree.

If you plan to graft then wait until the tree is strong and healthy. If your grafting for the shorter needles that makes sense. Otherwise - I see no need to graft as the tree has enough needles and buds to work with. Again - I would want to clean up & resolve that wound area before I did anything else........clearly you cannot  hide the wound site so you will have to figfure out how to make something from it........, Tom

I agree about waiting until you're sure the tree is healthy. I'm concerned too about the difference in growth rate between ponderosa and JBP. JBP is very vigorous, and the scions' faster growth might cause separation of the grafts down the line.

It seems to me I remember a post by Michael Hagedorn on this topic on his blog. You might want to check is old blog posts. I am seeing him in two weeks and will ask him about this subject and get back with any comments.

JRob

Just checked his site. Yes there are 2 posts one in 2010 and one in 2011.

Thanks Guys, My thought is to monitor it's health this growing season and try to get a good cambium layer built up for next grafting next spring.

JRob, I was at Michaels in February, he had several ponderosas receiving grafts from black and red pines. One small one he grafted years ago is looking very good.

Good luck with this one Jason. Smiley
