Mowing turf during drought
Do not mow turfgrasses suffering drought or other climatic stresses.
Grass suffering from lack of water should be watered deeply and
then mowed after the leaf blades have dried off. Cut at the highest
allowable height for your turf species. This increases the leaf
area and photosynthesis which results in more carbohydrates for
plant growth. It also encourages a deeper root system. Mowing at
the highest height and only removing a third of the leaf blade
at a time allows for more efficient use of water. Keeping your
mower blades sharp and balanced will allow cut grass blades to
recover more quickly and lose less water than if cut by a dull
Mowing weedy areas
Mow weedy turf frequently to avoid the patchy appearance that can
result from the uneven growth of weeds.
Mowing turf in shade
For shady areas, mowing your turf slightly higher than is normally
recommended will allow for more efficient absorption of light. This
will also reduce your mowing frequency. Higher cuts will encourage
deeper roots and infrequent mowing will leave fewer open wounds on
the leaves, reducing the incidence of disease.
