Goulburn plum, not again ?

Postby boom64 » September 11th, 2018, 9:28 pm

Hi All ,
After the bad news about Crown Gall on a Kunzea ,I have finally done a thorough check of all my trees .Results not very good. A tree I have had for a long time was covered below the soil line and unfortunately I have spread it about...lots of nobby lumps ,especially on newly cut branches .Now all in Bonsai heaven. Hard day.
A little unsure about one of my Goulburn Plums as well. This Tree has always had this growth on the base of the trunk, it has not grown and does not feel course like the ones on the Kunzeas. Maybe I am just being hopeful , if any one can help I would appreciate it.
Also found these lumps on a few branches as well ,from what I understand these are caused by insects and are not that bad ,branches can be simple removed with no harm to tree. once again if any one can confirm my diagnosis I would be very grateful.
Thanks John.

Yes, this sounds like an awful situation! I hope all ends well .... so hard to dump trees - must have been a crud day.

I am miles away from being an expert but those lumps on the Kunzea look similar to when I had a Gall Wasp on my lemon tree. I succeeded in ridding the tree of the issue with a hard prune over two years - cutting the branches with swollen lumps off and I still keep vigilant.

So again, I am no expert but these lumps look insect related to me.

I hope all goes well.

Hi John . Bugger about yor tree . I think your ok with the plum, it looks more like a root callus and if it's had it a long time and it was crown gall I agree with you ,you would of expected it to spread more on the tree . If you haven't already got them invest in some stainless steel tools which you can soak in bleach to sterilize them between trees .
All the best Craig

Thanks for the kind words Ryceman3 ,at least it clears a few spots on the benches. I will follow your advice Mark and cut back hard. Cheers. Hoping the Plum could be saved . Thanks Craig . I have a stainless set of tools and a large bottle of bleach now ,very easy to not worry about these things. Even cleaned my little bonsai shed and all of my pots. A valuable lesson learnt the hard way. Much appreciate the comments and advice .John.

Hi John,
So sorry to read about the loss of your infected plants :( . I'm interested to know how you initially got the disease? Can you pin-point the source? Was it one infected plant introduced into your collection? If so, was it a nursery bought tree or yamadori material?
:fc: you've now got this beat & wishing you find even better trees to replace your losses. :beer:

Hi K.C.R. pretty sure the initial source was from a collected tree ,that I have had for several years and had done a lot of work on. , I am probably my worst enemy as I always go for the most damaged trees. Especially if there is some deadwood involved . Starting to think Kunzeas might be a bit more vulnerable to this virus as I have not found any problems on my other natives. Found another tree today with the virus ,this was a tree that was recovering from collecting and had no work done on it .So in theory there should be no contamination via tools etc . Once again just below the soil line on a live vein as it joined a bit of deadwood. Going to be a bit more vigilant in the future. Regards John.
Hi Rory, I remember your battles with Myrtle Rust and I recently saw some Tea Trees covered with it in the Southern highlands. Not easy this Bonsai game. Cheers John.

Hi John,

Mate, I call your Gall and raise you a Myrtle Rust, a possum, a digging bandicoot, and a horde of ticks.

You had me wondering after looking at your dilemma. I went outside yesterday and had never put any thought into this before.
But I noticed that on a tree I acquired from a nursery that I haven't repotted yet looks like this.

I actually thought it looked lovely with the abnormal growth, but now I'm not so sure.
It has had fresh new growth bursting from all the abnormal growth too, that I just rubbed off recently, and as you can see keeps producing more.

Hi Rory ,yeah its a fun gig Bonsai :whistle: . The lumps look very similar to what I have struck. Have found that if you cut a branch about 3_4 mm or above and it blisters up instead of healing smoothly ,its all over. Check under the soil line ,there might be something there as well. Hopefully someone might chime with a little more information. Here are two pics of some of mine ,sometimes smooth other times really blistery. Good luck and let us know how it goes. John.
