Now that I have your attention … This post is about a common bacterial disease called Pseudomonas syringae , which frequently affects Japanese maples is still relatively easy to control. Often it misidentified as Verticillium wilting as the cause dieback tip. The Pseudomonas bacteria form purply-black discolorations mother, which is the result of a toxin produced by the bacterium that kills the cells. Twigs, branches and eventually the entire tree can die. Bigger and stronger growing trees are less susceptible, like some varieties. Do not prune maples in autumn (especially in the West) as the disease enters any injury and is encouraged by humid and cold winters. Any court, at any time of year, should be sealed with a liquid sealant immediately.

The control is three times. The first is to maintain its strong, healthy and free Japanese maples damage. The second and third are related: If you can keep your dry tree during wet and cold periods, ie half the battle. The other is chemical control, which is copper sulfate or bactericidal like. Consider using Phyton 35, a systemic bactericide. the top spray is recommended and drench bottom.

If you have problems with this disease, try a chemical potion after transplant or after heavy work root, perhaps ZeroTol. And if you live in an area with wet, cool weather in the fall until spring, prophylactic spraying season is a sharp idea.

Clear leaves and seeds especially maples-as broadleaf or vine maple is essential after the fall of the leaf as these landscape trees commonly planted are often carriers of the disease. Keep leaves and moss away from the base of the trunk, too.

Damage to the purply-black tissues of the Pseudomonas bacteria shown on this branch is typical of the disease.

The color change stem damage above and below a pruning cut (seen as a white piece), where bacteria probably entered the Japanese maple.
