When assessing the health of our street trees, keeping an eye out for signs of trouble is key. One of the more common diseases that affect larger growing tree species is bacterial leaf scorch. Bacterial leaf scorch will eventually affect leaf growth, and can possibly be fatal. There is no cure for the disease, but being on the lookout for noticeable changes in your trees, especially oaks, and calling in experts to test for the disease, can keep your trees happy and healthy in the long term.

Pruning is essential when we think about overall tree care and maintenance. Pruning removes branches that are less than desirable, such as those that are broken, damaged, diseased, or dead.

Imagine you are in the middle of a yard project when a heavy rainstorm rolls in, washing away some of the loose soil you had laying around. You see it travel down a nearby storm drain, which you know leads straight to a local waterway. It’s just soil, which is natural, so it’s not really a problem, right? Not quite! Sediment (loose particles of soil, sand, and clay) is considered a pollutant, and is the most common pollutant in US waterways according to the Environmental Protection Agency. Sediment often comes from construction projects, including small home projects, but it is also the result of erosion. Read on to find out how erosion and sediment runoff affect streams and rivers, and how trees can help!
