How Often To Mow St Augustine Grass


How Often To Mow St Augustine Grass

A healthy St Augustine grass lawn can grow at an extremely fast rate, in fact, a St Augustine lawn which is receiving adequate water and nutrients can grow up to a foot high every four weeks in the peak of Summer. This brings us to the question of just how often should a St Augustine lawn be mowed.

Benefits of Regularly Mowing St Augustine Lawn

While St Augustine grass is not one of the most aggressive grass types for creeping into garden beds and pathways, it's runners will still naturally grow into surrounding areas and take over if left unchecked.

Regular lawn mowing forces the grass to use it's available energy to repair it's grass leaf which was damaged from the lawn mowing. This process also helps the lawn stay green and healthy, in a process called "tillering".

As the lawn uses this energy to repair and grow more green leaf, it will greatly reduce all it's efforts to spread, meaning far less lawn invasion into garden beds and pathways.

Matching Lawn Mowing To Lawn Growth Rates

All St Augustine lawns will grow at different speeds, which will be dependant on the type of St Augustine grass being used, the weather and time of year (ie Summer or Winter), the availability of nutrients from fertilizer, soil quality and available water.

Regardless of the speed of growth of your own St Augustine lawn, the mowing principle remains the same, always try never to remove more than one third of the green leaf in a single mowing.

This regular mowing will ensure the lawn is not scalped from mowing, keeps the lawn looking green and healthy, and controls the thatch build up which everyone with a St Augustine lawn is well aware of.

The regular mowing will also have the added benefit of removing many small weeds before they have a chance to grow more seed heads and reproduce more weeds.

Mowing With The Seasons

Mowing St Augustine Grass In Summer
So with this in mind, a very healthy Soft Leaf St Augustine lawn may need to be mowed every 5-7 days in Summer, while a lawn in average condition may only require mowing every 2 weeks through Summer. Leaving a St Augustine lawn to grow too long between cuts in Summer will greatly increase mowing times, make mowing extremely difficult, produce massive amounts of clippings, grows the thatch layer and risks damaging the lawn from mowing.

If you hire a lawn mowing contractor to service your lawns, then with this doubling of service times and efforts, expect the mowing price to also double.

Mowing St Augustine Grass In Winter
As we proceed into Winter, the lawn will significantly slow it's growth rates, and as such we will adjust our mowing frequency according to the growth pattern. This is most often mowing every 4 weeks. We generally don't recommend leaving lawns for longer than 4 weeks between mowing in Winter. Winter lawns can be highly deceptive in appearances, while many Winter Buffalo lawns may look like they may not be growing much in the colder months, this is because the lawn is using it's energy to strengthen itself in it's thatch layer instead of growing more green leaf.

So while the green leaf may not look like it's growing much, the thatch layer is growing, and for the best St Augustine lawn care, this thatch layer always needs to be properly managed in all St Augustine lawns.

The regular Winter mowing will also aid in keeping the lawn leaf green through Winter.
