How to Plant Pampas Grass


If you are interested in planting ornamental grasses in your landscape project, consider investing in some pampas grass. It is a gorgeous plant that will fill up any barren areas in your yard with its swaying fronds. Pampas grass can double as a privacy barrier since it grows quickly, high and thick. Keep a few things mind, though, when designing your plantings of this grass.

Step 1

Choose a site where the grass will have plenty of space to grow. Some varieties of pampas grass will grow up to 10 feet high so make sure it won't be blocking any view you enjoy now. Measure an area 10 feet by 10 feet from any other plants or objects. This is how much room you can expect your pampas grass to use.

Step 2

Dig a hole in the center of the 10 square foot area at least double the size of the root ball of your plant. Typically the grasses are sold in gallon containers and so a 2-foot-deep hole is suitable. Make sure your site has good drainage and is not in a boggy area or the plant will rot.

Step 3

Remove the pampas grass from the plastic pot you bought it in and loosen the dirt a bit so the roots are able to spread out in their new hole. They will grow very quickly and easily so there is no need to add any amendments to the soil, unless you have very sandy soil, in which case you might want to add some well rotted compost.

Step 4

Set the grass plant into the hole so that the crown of the plant is ground level. If the hole is too deep, pile some of the removed dirt back in before you set the plant in place. Pack the soil in around the plant and tamp it in place with the heel of your foot.

Step 5

Mulch around the pampas grass to conserve moisture. Water the plant at least once a week during the first month or so and maybe more if your weather is hot and dry. It should grow almost carefree for several years.

Tips and Warnings

  • This grass will die off over winter in freezing temperatures, but it will come back in the spring.
