I can't tell you how often I'll be using the hose and lazily just let it drop to the ground. This is bad. Back to being a farm girl, I was told to never allow the hose to hit the floor. Why? Because the nozzle picks up all sorts of bacteria and fungus and other unpleasant things the eye can't see and all of that......gets transferred to your plants when you water. You're plants might start to have issues and you might never realize the "disease" came from your hose. So keep your nozzle propped up; never let it hit the ground.
