Sidewalk? What sidewalk? Here are some negelected and over grown bushes that has grown over the sidewalk. These are infested with bag worms. Be sure to trim your bushes at least twice a year to avoid them from getting out of control. If they are out of control already, wait until late fall and prune them back to a controllable size. Be sure to occasionally look up close at your bushes to be sure that they are growing healthy. Losing a mature plant is costly to replace, plus it leaves a huge gap in your landscape to fill.
