Proper lawn mowing heights are important for all lawn types, and especially a Buffalo lawn such as Sir Walter or Palmetto, the differences in mowing heights can mean big differences in lawn health, thatch control and water usage.
A Buffalo lawn which is regularly cut too short will result in greater water evaporation from soil, putting the lawn under stress and increasing water usage. A short lawn can also mean ongoing poor health due to lack of photosynthesis.
If it is maintained too high, then growth rates and thatch can increase more rapidly.
At all times, we are trying to find just the right balance for our own individual Buffalo lawn.
Mowing Heights and Photosynthesis
Photosynthesis is the process which plants and lawns use to power their growth and food conversion from nutrients into carbohydrate foods.
The longer the leaf of a lawn, or the higher it is mowed at will directly impact on how fast or how slow the lawn grows. Longer leaf means faster growing and repairing lawn, and shorter leaf means a slower growing and repairing lawn.
Many problems which occur in Soft Leaf Buffalo lawns is often due to the lawn being mowed to low. Buffalo lawns like Sir Walter and Palmetto like to have a longer leaf, and prefer being mowed at a higher than average height when compared to other warm season grass types.
25 to 60 millimetres is an optimum mowing height for Buffalo grass, mowing lower than this may result in an ongoing unhealthy lawn.
Shade and Mowing Heights
Shade is also a very big factor in lawn mowing heights. If you chose a Buffalo lawn for it's shade tolerance and the lawn is planted in an area of high shade, then the mowing height will need to be raised in the shaded part of the yard. This allows the longer leaf blade to trap more sunlight in order to conduct enough Photosynthesis for it's survival.
Seasonal Mowing Heights
As our lawns approach Winter the available daily sunlight reduces, and with it so does the ability of the lawn to photosynthesise it's food. In order to maintain a healthier Buffalo grass lawn in Winter it will be necessary to raise mowing heights prior to and during the Winter season. This allows greater photosynthesis and food supply under the low light conditions of Winter.
