However, for a complete lawn renovation, professional assistance is highly recommended due to lawn replacement and treatment.

Stage4: Water the lawn. Continuous watering is essential, considering the lawn is put up in the hottest months. Water is important for lawn establishment.

Stage5: Let it grow. By the end of the hot season, the lawn is usually well established, and the glory of your backyard is returned. The professionals will, however, return and add more seed as a dormant seedling.

Stage6: Regular treatment. All your lawn requires now is regular treatment and instant removal of any course grass you spot.

Let it Be

 Another way to deal with different grass types on the lawn is to let them be. More species of grass on your lawn are considered better. The lawn looks less uniform on a close-up look, but a large spatial look gives it a gradual shift in appearance. Different grass species in your yard provide a smooth transition between the cold and warm seasons of the year and a blend of sunnier and shadier grass spots.

Different species of grass on your lawn offer grass biodiversity. A transition from wet to dry seasons leads to a shift in balancing different species instead of having dead spots in the backyard. To make this method work best, establish the type of grass on your lawn and over-seed all types. Seeds are bought at local stores, or else you can let the lawn produce seed over time.


Spraying is an instant way to eliminate a certain type of grass on your lawn. Research and know the type of grass you have on your lawn, then apply a spray called ‘winter grass killer.’ The spray gets rid of vertical growing grass-like ryegrass and bluegrass. This means you only have lower horizontal grass left.

Lower grass like Bermuda, St. Augustine, and Kikuyu have different appearances. They may not give you your desired uniform lawn appearance. The vertical type, on the other hand, looks similar and can easily coexist. Therefore, the solution would be to remove all the lower grass and start afresh will a single type of grass.

Continuous Watering

Where you live may have a great impact on fixing the issue of different types of grass on your lawn. St. Augustine, for instance, does well in the South, so if you live there, water it continuously for a few weeks. The grass will thrive and dominate for the rest of the year. On the other hand, if you live in the North, this option might not work for you. 

There are no dominant species in the North. Creeping bentgrass may seem to dominate, but once it develops patches of Kentucky bluegrass, it becomes difficult to separate. The solution on this side would be to decide the type you want to keep and get rid of the rest with RoundUp, then sod the grass you desire to have.

  • Once you spot grass patches, remove them by hand.
  • Once a patch becomes big and established, fork them out and add soil to level up, then reseed or lay patches of new turf.
  • Slash the coarse grass using a knife or an edging tool that cuts to the root, removes the debris entirely, and then reseed. After the seed is established, the coarse grass is pressured out of the lawn completely.
  • During the dry season, avoid frequent watering. Meadow grass which commonly grows as coarse amid your lawn has shallow roots and will be kept at bay.

Your grass growing region.

The first clue to the grass type on your lawn is your location. Grasses have climatic limitations just like shrubs and flowers do. A certain type of grass must blend with the region to survive all seasons and remain healthy. In the US, for instance, the northern half grows cool-season grasses, which flourish in the cold weather in the North but dries out when subjected to the hot climate from the South.

On the other hand, the South grows warm-season grasses that peak during the summer and dry out during the winter.

Common cool-season lawn grasses

  • Fine fescue. This type is the most shade-tolerant grass type. It’s best suited for yards with a dense shade. The grass includes spreading types and has an upright clumping growth.
  • Kentucky bluegrass. This is considered the ideal lawn grass in the US Northern region. It’s the best for winter hardiness, fantastic self-repair capacity, and is vulnerable to stress damage.
  • Perennial ryegrass. Ryegrass has a unique fast germination rate and establishment, thus best suited for both temporary and permanent lawns. It has good tolerance to cold and can withstand appropriate light shade.

Common warm-season lawn grasses

  • Bahiagrass. Also known as highway grass, bahiagrass is an aggressive warm-season perennial grass. It has a mat-like forming habit and is light green. The grass is favored by drought and is ideal in soil erosion control.
  • Bermudagrass. Bermuda grass is highly tolerant to heat. Its deep roots adapt it excellently to the dry seasons.
  • Centipede grass. Centipede grass is preferred for its slow maintenance though its growth rate is very slow. The grass does well in sandy and acidic soils.
