Some may not realize that different lawns should be mowed at different heights, and also that this height will change throughout the year. Weather along with the mowing schedule contributes to changes of mowing height the lawn needs.
Proper Mowing Practices
When mowing, a good rule of thumb is to never remove more than 1/3 of the grass blade. Cutting more than 1/3 of the blade off can stress the plant by reducing root growth that is essential for summer drought months. Unfortunately, during the spring rains, this means that the grass may need mowed every 3-4 days depending on how quickly it is growing.
Proper Mowing Height
Mowing height is not set in stone across the board, nor is it followed at that height throughout the year. During the spring months, a homeowner or even a mowing company may get a little behind schedule. If this were to result and the lawn has grown a little too tall, it may be mowed at a higher setting to prevent scalping the lawn or having excess clippings.
During the summer months, using the example of a fescue lawn, the grass will not need to be mowed as frequently and will typically be better to mow at a higher setting to help combat the summer heat and stress imposed on the lawn.
Before winter hits, it is a good idea to mow the lawn lower than usual. This is considered to be the final cut and will allow the grass to grow just a little, without overgrowing, before it goes dormant for winter.
Grass Type Affects Mowing Height
Different grass types grow at different times during the year and should be cut at different recommended heights. Cool season grasses, like fescue and bluegrass, can be mowed at a variety of recommended heights. It is recommended that fine fescue be mowed to a height of 1-3 inches, tall fescue between 1 ½ – 4 inches, and Kentucky bluegrass between ¾ – 3 ½ inches. Warm season grasses like Bermuda can be cut to the recommended heights between ½ – 2 ½ inches and Zoysia grass is recommended to be between ½ – 2 inches.
Sum it up
Following the proper mowing schedule and mowing the lawn as needed depending on the weather conditions, mowing the lawn with sharp mower blades, and following the proper lawn care program will greatly benefit the health and appearance of the lawn.
It is always a good idea to consult with a lawn care professional and ask any questions you may have. Look around, ask friends or family, and research companies on the Better Business Bureau to find a company that you can trust.
