and others, grow within the tree using the sap as a nutrient source and causing fluid to exude from bark. The flux can become sticky to slimy in texture, and often has a sweet, fermenting, beer-like smell. Steps should be taken to prevent damage to the root system and trunk, especially near the crown. Wetwood bacteria are not tree pathogens. In shade and ornamental trees, wood becomes soaked, oozing, or bleeding in this condition. Naturally occur- . also affect branches. As the sap is used, oxygen in the heartwood is depleted (creating anaerobic conditions), methane is produced, the pH of the sap is increased (pH 6 in healthy trees to pH 7 to 8 in wetwood), and a high pressure develops in the wood (60 psi in affected trees vs. 5-10 psi in wetwood-free trees). The bacteria enter through open wounds in the bark. It results in a water-soaked, oozing or bleeding condition of wood, which occurs in the trunk, branches and roots of shade and ornamental trees. All wetwood contains bacteria, so there is no distinction to be made. the heartwood down the trunk, just below the area of infection. When stressed or wounded, or if the pressure becomes too intense, the bark will release the wetwood fluid at any weak point, especially at wounds.

However, it inhibits the development of wood-rotting fungi, which are unable to grow in the affected wood because of lower oxygen content. Apart from preventive treatments, an arborist helps treat active diseases and pest infestations. Free-living bacteria, yeasts and filamentous fungi on the surface of the bark are stimulated and grow within the fluid as well. It's not clear whether this condition can affect every tree species. However, fluxing diseases are also found in other species, including apple, birch, beech, hemlock, linden, mulberry, maple, oaks, Russian olive, and many others.
