So, you think you’re on top of your lawn care maintenance, but what happens when you mow your lawn too often? Well, you could be doing more harm than good. Overall, the key to keeping a growing lawn healthy is mowing it according to its growth. If the weather is cool and the growing is minimal, mow less frequently. If it’s during the growing phase, mow more often. Don’t mow the lawn just for the sake of it or on an inflexible schedule.
