How to Grow Thick Green Grass

By Lauren Wise ; Updated September 21, 2017

Everyone with a lawn hopes that their grass will grow thick, lush and green all season long. To achieve this, it is important to take care of your grass correctly. This includes mowing regularly at the highest setting, watering your lawn at the right time and adding fertilizer as needed. There are some key things to keep in mind when working your hardest to gain thick, green grass.

Mow with your mower blade at its highest setting to help the soil retain moisture and nutrients, and to make it less susceptible to diseases.

Mow your lawn at least once a week to keep weeds at bay.

Water your lawn deeply with about 1/2 inch of water when you notice the grass blades curling.

Do a pH test on your soil to see exactly what nutrients your lawn needs.

Apply a layer of fertilizer to your lawn, according to the results of your pH test.


Things You Will Need

  • Soil testing kits
  • Fertilizer


  • Use a mulching mower, which leaves clippings where they land. These clippings protect your grass and add nutrients to the soil when they decay.
  • It is best to water first in the morning and then in late afternoon. Occasional, regular deep watering, done in stages, helps roots establish themselves more deeply.
  • PH kits are available at garden stores and nurseries. Test and fertilize every spring and fall.
