Mowing grass works best when the grass is dry, as grass tends to bend over from the weight of the rain, making it difficult to get a straight cut. It also clumps inside your mower cavity and on your lawn, which can lead to dead grass underneath the clumps if not raked promptly.

When the weather gets hot and dry, Tom says that many homeowners have a tendency to skip regular mowings because their grass is not growing as much. Skipping mowing tends to compound the problem, however.
