Bacteria, commonly found in soil and water, take up residence in young trees or gain entrance to older trees through wounds. Proper irrigation and fertility management will reduce wetwood symptoms. The liquid is a mixture of the wetwood bacteria, The attacking bacteria in a slime flux infection alters wood cell walls, causing moisture content of the wood to increase to the point of injury. The infection causes production of large amounts of moisture in the wood of trunks or large branches. Many trees are susceptible to bacterial wetwood infection, including: apple, birch, elm, fir, hemlock, hickory, linden, maple, mulberry, oak, pine, poplar, redbud, sycamore, and willow. The elm trees that line boulevards in many communities are a prime place to spot these wet, slimy weeping spots, but a number of other trees can also exhibit the symptoms. 1).The disease is not usually a serious problem but the appearance can be alarming.
