What happens if you mow more than 1 3?

If you neglect your lawn for a few weeks during its active growth period and it gets too high, you will impair the root growth if you cut more than one-third of the blade to reach the recommended height. Growth will slow as the grass puts its resources into the leaf tips to help them recover.

Should I mow vertically or horizontally?

The size and shape of your yard plays a part in what direction the rows should go. If your yard is more wide, mow in horizontal rows to cover the longest part of your lawn with the least amount of turns. Longer lawns can be cut vertically for the same reason. If your yard is more of a square shape, congrats!

Why does my grass look brown after I mow it?

This causes the tips of the grass to die and turn brown. You can easily fix this by sharpening or replacing the blades on your mower.

Why should you not mow short?

When they are too short, the grass is harmed by the heat of the sun and is exposed to too much sunlight. Additionally, the shorter grass then allots more energy toward growing the blades instead of creating a deeper root system. In turn, this weakens your grass, blades, roots, and the overall structure of the lawn.

Is it OK to mow grass every 2 weeks?

Having a set day every week regardless of the time of year is not always the best approach. Examining the lawn each week and noting how long the grass is at that time will yield much better results.

Does the direction you mow your lawn matter?

Change the mowing pattern each time you mow. Grass develops a grain based on your cutting direction, tending to lean towards the direction you mow. Alternating your mowing pattern causes upright growth and helps you avoid producing ruts in the lawn.
