Help Save my Japanese Maple! *Pics*
Comments (18)The sunken area at the base appears to be to be canker. Had to remove a Ukigumo JM earlier in the season for this very reason. I have seen allot of this over the last few years. Have seen allot of it on crabapples, Japanese Maples, and other maples. Plants sometimes beat the pathogen, sometimes not. If they are going to beat it, then expect to see callus to form around the edges of the sunken area. Even if the callus forms, it is far from certain. Once the tree goes dormant for the winter, the canker will often gain the upper hand again. However if the callus does not form by end of summer, then from what I have seen, it's almost certainly a matter of time before the tree is killed. As for how your plant became infected, I suspect that a number of low cost and/or large scale producers have gotten very careless over the last 5-10 years. There has been allot of apparent disease increase in allot of other plant groups as well over the same period (Aster Yellows seems to be everywhere anymore, to the point it's getting rather difficult to get disease free coneflowers, saw this Saturday at the largest local nursery). I'm sure part of it is due to producers having a difficult time the last several years, therefore cutting corners, poor training, poor enforcement, less responsible labor, etc. But also Big Box Store has little incentive, as they know Q Public is unlikely to know anything about disease and will be back again next year to buy another one.

Comments (1)Gina, things might be ok time wise. At least it is not the heat of summer! Far as the japanese maple goes just try to keep the pot from cooking in the sun or getting waterlogged. You sound attentitive so I bet you will water it enough. Just make sure it drains. How large a tree was this? was it one of them weeping ones? I even like species japanese maples so even if it was cut to below the graft line you might end up with something interesting. Post a few pics if it gets any foliage from dormant buds on the trunk and we'll try to guess what you saved....See MoreSaving a Japanese Maple
Comments (4)First, mole are not the problem - they are carnivores and don't eat plants. There is a possibility of some other sort creature that might have fed on the roots (voles?) but can't confirm with the photos provided. Regardless, the tree now has a very compromised root system and will need some serious TLC if to survive. You have two types of JM showing based on both red and green branches. Green is most likely the root stock (straight Acer palmatum) and the red is the grafted top portion, which I assume to be a red laceleaf by the shape/habit of the tree from the first photo. So no need to graft any of the green further down - that's already what it is and will very likely sprout some latent shoots all on its own. All I would suggest for the time being is keep it out of direct sunlight, water as needed and just keep a close eye on it. No more fertilizing!! One should never fertilize a stressed tree and it is doubtful the Happy Frog is of much value in a container situation anyway (dry organic ferts are not very effective in a container - only with inground plantings). You can use any water soluble or liquid fertilizer you prefer but wait until at least midseason when the tree has stabilized a bit from the transplant shock and root disruption....See MoreSave my Japanese maple tree
Comments (1)Not sure there is a lot you can do for it at this point. JM's are prone to a variety of soil pathogens that can severely damage or even kill the tree. This one looks like it might be dying a slow death :-(( What I would suggest is getting rid of all the rocks - they are not helping and could be hurting the tree. And carefully prune out all the dead wood you see. It will be a pale color, often gray, compared to the dark color of healthy tissue. Dead wood tends to harbor insects and allows an inroad for other disease issues. Then just keep the tree adequately watered - not too much, not too little. Just don't allow the soil to dry completely. And no fertilizer!! If the tree does not respond or seems to get worse, then it's time to contemplate removal. But I would be cautious about replanting with another JM until you can confirm what caused the problem (and that may involve a path lab analysis), as some of these soil pathogens will infect any other susceptible species planted that space. Going forward, you might want to post any other questions you have about Japanese maples on the Maples forum. This one is pretty much inactive and most JM enthusiasts post there....See Moredefrost49
