Summer is a time for outdoor fun and warmer temperatures – but the not-so-good side of summer is seen when tree problems manifest themselves. Here, we will talk a bit about some common summer tree diseases that you may have seen, but do not know much about.
Slime flux, sometimes called bacterial wetwood, is severe rot in a tree’s branches and trunk. This disease is thought to be caused by a bacterial infection of the tree’s outer heartwood and inner sapwood, and can be brought on by physical or environmental stressors. In yellow poplar, cherry, oak, maple and willow trees, a variety of bacteria can cause slime flux. Trees afflicted with this disease are waterlogged, and can be seen to ‘weep’ from open wounds. The only real option in cases of slime flux is tree removal in Guilford CT, as there is nothing that can be done to stop further rotting.
Mildew is a common summer tree problem, and it usually appears as white powder on leaf surfaces. The appearance of the mildew is from millions of fungal spores, which spread by air and cause disease in other nearby trees. Mildew can affect many different species, and it is a product of moist conditions. If humidity can be controlled, so can the mildew. Don’t plant new trees in shaded areas, and allow plenty of room for air circulation and growth. Hire a professional to trim the tree as necessary.
The name of this disease is quite apt; the mold closely resembles chimney soot. Though it looks bad, it rarely causes damage to the tree. Sooty mold can grow on any tree, but is commonly seen on maples, elms and box elders. It’s associated with arid conditions and high temperatures, and it can be prevented with thorough watering and insect control.
“Canker” is a term used to describe a dead area on a tree’s branches, trunk or bark. The fungus that causes canker usually gets in through a wound, and it can spread rapidly. To prevent tree canker, choose species that can easily fight off invasion by fungal pathogens. Plant in an appropriate area, fertilize new trees well, and practice good weed control habits after trees are planted. During the dry summer months, water your trees, and hire a pro to cut off affected limbs and branches. Large cankers on the main trunk of a tree may necessitate tree removal in Branford, CT.
Most people don’t think much about summer tree diseases – that is, until a tree in their yard is affected. By learning about some of the most common tree problems, and by learning how they can be treated and prevented, you can keep your trees growing for many years to come.
