[IBC] Coral maple
Sounds very much like Verticillium wilt to me. I've had it randomly
destroy 3 of my very best Maple varieties. Crimson Queen was 50% killed off and the surviving part has now grown into an acceptable garden plant in the subsequent five years. If the list agrees, I'd cut out well below the affected areas and dispose of cuttings cleanly. Remember to sterilise tools afterward. Good luck Kev Bailey North Wales I have a coral maple form nursery .. put into a growing pot since 4 weeks all seemed ok and it started sprouting .. today I noticed that 5 shots in different branches (4 leaves already out + small central stem ) were limp we had a rainy day and the plant is not very much exposed to wind nor to rain directly It is the first time I am dealing with this Coral specie I am used more Desojo and Trident might be a roots fungus attack ?

[IBC] Coral maple
HI Kevin
I read a few pages I have in my files on Buergerianun they say about Verticillosis as a nasty one adviced to treat with Bentonyl 1% or burn the plant So I trow away the plant and washed the pot with chlorine , as well as tools. I hope anyone else of my maples has been contaminated 2 cuttings I made from the same Coral maple has been trashed too ,one was ok the other one had the same symptoms wilt new growth .. Will call the nursery on monday and tell them .. Thanks again for your informations Theo kevin bailey wrote: Sounds very much like Verticillium wilt to me.

Sounds very much like Verticillium wilt to me.
The limp stems sounds like a root problem. It could be Verticillium, or it could be something else, like compacted soil in the root ball. Don't panic yet.

If the list agrees, I'd cut out well below the affected areas and dispose of cuttings cleanly. Remember to sterilise tools afterward. Since Vert is a root problem, pruning isn't going to do much good. Some trees, if in good health, and not stressed by drought, will fight off the fungus themselves; susceptible or weak trees will die. You should look at your tree's roots for signs of decay or soil compaction. There is no good way to tell if you have Verticillium without disfiguring the tree, so don't bother unless it's a goner. But keep it away from other trees so you don't spread hypothetical spores. If the tree dies, get rid of everything: Tree and soil. Sterilize the pot before using it again. -- Nina Shishkoff Frederick, MD ************************************************** ****************************** ++++Sponsored, in part, by Evergreen Gardenworks++++ ************************************************** ****************************** -- The IBC HOME PAGE & FAQ: http://www.internetbonsaiclub.org/ -- +++++ Questions?

HI Nina
the whole thing happened like that: I bought the maple I transplanted 14 days ago and it was ok It started sprouting and having green leaves The small twin trunk it had started sprouting also Saturday morning it was all covered and rainy .. but the pot was in a good place not exposed and soil was not wet nor dry In the morning I noticed the small twin trunk had its leaves a darker green and I thought might be a sucker from the grafted trunk ( I sow later on it was NOT grafted ) in the evening when back home all leaves down and the stems were wilt so I asked in the net as I few days ago something about coral maplesand related problems cought my eye . The down part of the main trunk ( nebari )was brownish but it is normal as after 2 years the red color disappers.. But one of the top branches that has been cut and reduced and sealed I noticed was starting to decay and loosing color So I preferred for 20 $ stock not to take the risk of infecting my others maples . The earth I used was home made and sterilized with microwave and steam 5 min power 9 and contained akadama and sand plus leaf mould ( oak leaves )top microwave power ) the pot was just newly bought to make it grow for a while in that container I gave ST :-) with the watering thanks for all this concern Theo Nina Shishkoff wrote: Nina reads too late: So I throw away the plant and washed the pot with chlorine, as well as tools. Theo! You panicked! If I had caught you in time, I would have advised you to slice at the base of the trunk with a razor blade, and look for brown streaks in this year's wood. That's a sign of Verticillium. Root problems all have the same sysmptoms: leaf death and stem wilt. You can't tell one from another from symptoms alone. Granted, all root problems are serious, but some can be fixed. -- Nina Shishkoff Frederick, MD ************************************************** ****************************** ++++Sponsored, in part, by Evergreen Gardenworks++++ ************************************************** ****************************** -- The IBC HOME PAGE & FAQ: http://www.internetbonsaiclub.org/ -- +++++ Questions?

BODY {font-family: Arial; font-size: 10pt;}
I have been growing a Coral Bark in a wooden box for 4 years now. It is doing well never had die back. it's as hardy as any of my Maples. I have about 40 varieties of Acer Palmatum at last count. This Past fall I bought 2 more Coral Barks. this is definitely one of the most striking Japanese Cultivars, and a favorite. It shows off its CORAL bark in the winter when it is subjected to cold conditions. I find it looks its best in the spring before it loses its coral color, and has leafed out. 2 of the trees were grafts and ! Was, one that wasn't a graft was as good as the grafted trees. It seems to be a very Hardy tree.

Nina Shishkoff wrote: Theo said offlist: as the maples has just been bought and transplanted IT WAS JUST TRANSPLANTED? Transplanting can cause shock with exactly those symptoms. A tree that has been transplanted should be kept in shade and watched carefully until it is transpiring normally. Verticillium is a terrible disease, and people should be ready to toss out a diseased tree with no regrets, since if the disease spreads, it willl mean greater heartbreak. But don't be hasty, folks. -- Nina Shishkoff Frederick, MD ************************************************** ****************************** ++++Sponsored, in part, by Evergreen Gardenworks++++ ************************************************** ****************************** -- The IBC HOME PAGE & FAQ: http://www.internetbonsaiclub.org/ -- +++++ Questions?

Hi Nina hi everybody maple lovers
I need your science My second coral bark maple is slowly dying back from the cuts of some upper branches they started very slowly getting black. I was looking how would react and if maybe stop when reaching the nodes where others twigs come out.. apparently one twig is looking wilt not neat not dead yet which product should I use ? Should I cut off the black part in the sound red bark ? Thanks Theo Nina Shishkoff wrote: Sounds very much like Verticillium wilt to me. The limp stems sounds like a root problem.
