Soil under a lawn that has been heavily fertilized or frequently treated with pesticides may be deficient in these elements. Removing more can be very stressful for the plant and increase pest and disease problems. Mow when the grass is dry. During the summer months, cut the grass higher to help retain soil moisture. Keep mower blades sharp.
Dull blades wound the grass and make it more vulnerable to pests and diseases.
Alternate your mowing pattern frequently to avoid compacted ruts. If rust disease is present in your lawn, clean your mower between mowings to prevent spreading the disease. Deal Sensibly with Weeds Decide how many weeds you can tolerate. It is not realistic to expect a completely weed-free lawn. Dig up weeds by hand and sprinkle grass seed on any bare spots so weeds can't fill in.
