Here in Texas homeowners take great pride in their trees. Not only are they a source of beauty but also provide shade from the intense summer heat. But even the biggest, baddest trees can catch diseases and if you aren’t vigilant an infection can lead to permanent damage or even the death of the tree. Here are 4 common diseases in Texas to be on the lookout for.
Oak Wilt is caused by a fungus initially from Latin America and is carried by beetles that feed on the sap of oak trees. It affects both red and white oaks but is more common in red oaks. If your tree is infected, you will want to prune it only during extreme temperatures. Painting the wounds on oak trees with tar can also prevent other insects from entering the tree and causing further infections.
Affecting several types of trees in Texas including, pecan, elm, sycamore, and oak trees, hypoxylon canker is a fungus that causes growths and eventually death. It attacks trees that are left vulnerable from insect infestations and droughts especially. You will see branch dieback and bark falling off the trunk. The best way to prevent hypoxylon canker is to make sure your trees are well watered during dry spells.
A rare bacterial infection spread by insects, mainly leafhoppers. The infection restricts the flow of water from the roots to the rest of the tree. Several trees, including oaks, elms, sycamores, and boxelders are all susceptible. As the tree is deprived of water the leaves will start to brown around the edges. The infection will severely stress and weaken the tree leaving it open to other pests and diseases.
Typically targeting fruit trees, fire blight can decimate orchards here in Texas. The bacteria spend the winter in cankers on the tree. In the spring when the tree starts to grow it emerges as an ooze from branches. The blossoms and leaves of the tree will turn black and droop. The infection can spread to neighboring trees via wind or insects. Fire blight can be controlled by trimming branches with host cankers.
