DIY Answers to 10 of the Most Common Lawn Questions


The snow is melting and your grass will soon be turning green.  That means it’s growing. That means you need to mow it. Do you have lawn questions that you’ve always been afraid to ask? We’ve compiled the answers to some of the most popular lawn care questions.


  • How high should I mow my grass? Mow to a height of 2 ½ to 4 inches, with 3 inches being ideal. This may seem long, but by keeping your lawn at this height, the grass will be better able to photosynthesize and stay green.
  • How often should I mow? Your mowing frequency should vary according to how fast your lawn is growing. To keep your lawn healthy and thriving, you should try not to cut off more than 1/3 of the height of your grass plants in a single cutting.
  • What is the best time to mow? Late afternoon and evening are the best times.
  • How often should I water my lawn? If it doesn’t rain over the course of the week, your lawn will need 30 minutes of watering once a week.
  • What is the best way to prevent weeds? Grow a thick, healthy lawn. When a lawn is thick, there isn’t room for weeds to grow.
  • When is the best time to fertilize my lawn? In the early spring. Read the instructions on your fertilizer label.  Some formulations require application to a wet lawn; others need to be watered after the fertilizer is applied.
  • When is the best time to plant new seed?  Spring or fall. Late spring is best if you live in a warm climate and will be planting warm-season grass.  Early fall is ideal for planting cool-season grasses, because the soil is still warm for quick germination, but the air is cooler so the new plants won’t be stressed by the heat of summer.
  • What is the best pattern to mow a lawn in? Some people mow their lawn in stripes, some in circles and some in squares. Switch it up. Your lawn will grow in the direction that you mow it in, and by varying the patterns, you will keep your grass looking uniform.
  • How often should I aerate compacted soil? Aerate your lawn once a season, early in the year when your grass will quickly grow to fill the holes you make in the soil.
  • What are the benefits of applying compost to my lawn? Grass and other plants grow better in nutrient-rich soil. If the soil in your yard has a low nutrient level, adding a layer of compost will give your grass more of what it needs to grow.
