How Often Should I Mow My Lawn?
The most important rule here is never cut off more than 1/3 of the grass leaf length. During the growing season, it is recommended that Bermuda grass and St. Augustine grass be cut every 4-5 days. However, no one other than golf courses follow this practice. Most commercial and residential lawns are cut on a weekly basis. Therefore, simple math shows that if you mow your lawn on a weekly basis, then you are 40% over the recommended time. Some people want to have the lawn cut on a bi-weekly basis. Mowing on a bi-weekly basis would be letting the lawn grow almost 200% more without cutting than recommended.
To have a healthy lawn, you need to mow regularly (at least weekly during the growing season), adequate watering, and proper fertilization. Mowing your lawn, during the growing season, any less than weekly, results in weak grass, allowing weed invasion and/or loss of turf.
