Your grass thrives best when your mower blades are set to 3.5 – 4.5 inches. Allowing your grass to grow to this height will allow it to get more light during the peak sun hours and convert the light into more nutrients for the roots and surrounding soil.
Some other helpful mowing tips include:
Cut your grass only as needed to avoid removing more than ⅓ of the grass height each time.
Leave the mowed clippings on the grass to provide extra moisture, shade, and beneficial nutrients. However, you don’t want to suffocate your grass. So if the clippings are piling up, they should be raked or removed from your lawn.
Monitor the condition of your mower blades on a regular basis to confirm they are sharp.
Try not to cut your grass during the hottest part of the day. This can dehydrate your lawn, causing it to turn brown.
