Sap oozing on Deodar Cedar

15 years ago

Hi all! I'm hoping one of you experts can give me some good news on a problem that's occuring with our Cedrus deodara 'Kashmir'. I recently noticed several very small branches that had turned completely brown, and while pruning them off found sap oozing from the trunk in the area of the dead branches. The rest of the tree appears healthy and is pushing new growth. The tree was damaged about 2 yrs ago when a large double-leader type branch broke and tore the bark, perhaps inviting pests or disease. We also had a terrible drought last year which stressed many of our trees. I'm leaning toward a canker type disease from my limited research, but hoping that's not the case as there doesn't appear to be much chance of a positive outcome. I'm attaching a couple photos of the sappy area, and the whole tree.

This picture also shows a dark band above the sap -- thinking that could be a bad thing.

Could this sap flow be normal, and the dead branches only a coincidence? (wishful thinking here)

Thanks in advance for any insight and suggested treatment.

Kim

    Not looking good. I'd bet almost with certainty that is cytospora canker. What you wrote about an entry wound area seems-likely to be where the beginnings, began. There is no cure. I'll link you to an article.

    I had cytospora canker on one of my big Picea abies 'Reflexa'.

    Yes,the accepted theory out there is there is no cure.

    This disease spread quickly and the conifer was bleeding a lot of sap. I decided I had nothing to loose and trying to save this conifer was paramount. I cut out all the infected area with a sharp knife. I then cleaned all the exposed area with denatured alcohol. I then applied a product called Doc Farwell's Seal And Heal. See link. After about a month of treatment the wound quit bleeding and now the tree is free from this disease.

    I'll leave these photo's up for a few days and then they will go away.

    I was hoping you'd post Dave. There's your solution, Kim.

    its worth a try ...

    but you know you are zone pushing...

    you have enjoyed it immensely ...

    is it really time to invest more heavily in it.. or get rid of it???? obviously.. your choice...

    i dont know.. if that big green blob of 'cure' would be better or worse than the weeping.. lol ...

    whatever you decide is fine with me ... just playing devil advocate ..

    Dax and Dave -- Thanks so much for your replies. I went back out and looked at the tree again this morning in the area around the wound. I'm attaching some more photos. There is a girdling type wound around the entire trunk in the area of the original wound. All of the sap is oozing above this point, and none below. I would try the treatment that was successful for Dave, but am not sure where to start and stop cutting because of the girdled area around the trunk. Can you suggest where I need to begin and end the wood removal, and if you think that would work in this particular situation. (We would normally have made a cleaner cut of the branch, but because it was tearing the bark we didn't cut further. I should have gone back and made a cleaner cut after the bark healed.)

    Thanks again!!

    I don't know Kim. It appears the disease has spread to far.

    That being the case I would remove it and if so inclined go buy another one.
    On the other hand since now is not the time to plant try the treatment...what have you to loose. If not recovering by this fall then go ahead and remove it.

    Each wound where it bleeds sap needs to be opened up and cleaned. In the case where several are close together remove both with one cut.

    With regards to the girdled area around the trunk. That injury could have been caused by being tied off to long to the stake with improper securing method before you purchased it. Just a guess however. I always use stretch tape.

    Good luck,

    I think I'll give it a try and I've ordered a quart of Doc Farwell's Heal and Seal. I'll report back with results. Thanks for the information Dave -- I really appreciate it.

    Ken, I think our tree will have a snazzy green polka-dot motif when I'm finished -- could catch on and be the next big fashion statement for trees :o)

    Hi ZKim, did you get to the bottom of what caused the Cedrus deodar sap to ooze ? Was there a remedy to help fix the problem ?

    It would be nice if there were sap tests for trees like blood tests for humans… If blood and nerves transport ‘Chi’ ( Traditional Chinese Medicine for ‘psychic energy) and oxygen and other plant-cell ‘synthesis and maintenance’ metabolites, then, maybe there is a special similar function in tree sap similar to blood.

    i wonder if shining a weak UV LED light at night would help it heal the wound ? Or similarly spraying the wound periodically with ozonated water or perhaps ozonated olive oil might help.

    A more spiritual solution might be to breathe in prana and exhale near ( a few (3) breaths to charge your body with some of the tree made prana-psychic-energy ) the tree with your hands near, but not touching the bark and directing some of you psychic energy from your own ‘Mighty I-AM God Presence to grant the tree and its God-Angel Presence ‘Perfection’.

    So, the moral of the story is to become your own tree-whisperer.
