How high to mow the grass
Often cutting height is a matter of personal preference.
Typically, you should mow the grass when it is 7,5-12,5 cm
(3-5 inches) tall. The proper cutting height range for a specific
lawn will depend upon several factors, including the type of
grass, the amount of rainfall, the prevailing temperature, and
the lawn’s overall condition.
Cutting the grass too short causes weak, thin grass plants,
which are easily damaged by dry periods and pests. Cutting
too short is often more damaging than allowing the grass to
be slightly higher.
Letting grass grow a bit longer—especially when the weather
is hot and dry—reduces heat build-up, preserves needed
moisture and protects the grass from heat damage and other
problems. However, allowing grass to grow too high can cause
thin turf and additional problems.
Cutting off too much at one time shocks the plant’s growth
system and weakens the grass plants. A good rule of thumb is
the 1/3 rule: to cut no more than one third of the grass height,
and never more than 2,5 cm (1 inch) at a time.
