Acer Palmatum dying slowly

Post  R3mco on Thu Aug 04, 2011 1:31 pm

Hi everyone,

I am having a problem with one of my maples in training.
About a month ago, some leaves were turning red, and within a week or two started dropping (in mid July).



Last week some pinkish (looks white on the photo) speckles started to appear on the nebari and the tree started to suck up less water.



I decided the tree might have a big problem, so I moved it to seperate it from the rest of my trees, not to cause infection on the others.
Within 2 days the infection tripled, so today I decided to put it in a more sunny spot, seems like the fungus (or whatever it is) feeds off of moist conditions.

Another photo, this time some distance:


Has anyone had this problem in the past, what is it, and how can i deal with it?
Perhaps it's already too late and i should bury it, lol Very Happy
Maybe bare root it totally, plant it in the ground and pray?

Any help is appreciated!! Very Happy

Greets, Remco

This could be Coral Spot fungus (Nectria cinnabarina)- and rather looks like it as well.

See here

I disposed of a trident maple that had it bad and saved another by prompt removal of the affected parts.

Not good news really

You could try a re-pot - cutting away any affected root and branch parts in the process , defloliate partially and cross your fingers.

Keep the tree in a bright airy place afterwards away from other trees

Thanks for the reply and finding the little bugger, Tim.

I've checked out some images on google on the Coral Spot, and it looks exactly the same, with the same symptoms.
Damn fungus, seems I'll have to cut all the stuff out, repot, and seperate from the rest.

I find it odd though that it happens to appear on a tree now. I've always worked in the same spot in my garden for years and never had any problems with fungus or other diseases. Maybe it just came with the plant and became active because I didn't seal wounds well when i did root pruning couple months ago.

Seems its time to properly clean my workplace and my tools with heavy duty stuff Laughing

Thanks again for the help!
