Warm season grasses can be divided anytime during the spring and summer. All ornamental grasses should be divided when they are actively growing but not while they are flowering. A good root system can’t be established when the plants are not active. Do not allow the soil to dry out during the growing season.
The soil should not be too wet or too dry, but it must be moist enough to allow for the roots of the grass to grow. Watering is not necessary, as long as the plant is well watered and not over-watered. Keep in mind that this is a perennial grass, so it will need to be watered once or twice a year to keep it healthy.

What happens if you don’t cut ornamental grasses back?
If you don’t cut back the grass, what will happen? The green is growing through the brown. The brown will start creating seeds, which will create a problem. The best way to deal with this problem is to cut back the ornamental grasses that are growing in your yard.
You can do this by cutting back on the number of plants that you have. For example, if you only have one or two plants, then you can cut them back to one plant. This will help to reduce the amount of seed that is being created. However, this is only a temporary solution.
If you continue to have a lot of green in the yard, it will be very difficult to get rid of all of the weeds that have grown up around the plants. So, the best thing to do in this situation would be to plant a new crop of grass.
Can you dig up and replant ornamental grass?
If you want to replant, dig a hole twice the size of the circumference and just below the depth of the transplant. If you want the crown of the plant to be slightly above the soil surface, mix in a bit of compost to the planting hole, water, and cover.
Once the roots are established, you can start watering and fertilizing the plants as needed. You can also add a few leaves or twigs to help attract pollinators.
How long do ornamental grasses live?
Perennial ornamental grasses live for two or more years. Annual grasses only live for one growing season because of their natural growth habit or they are not hardy in our climate. Grasses have growth habits that can be either clumping or spreading. Grasses can be divided into two main groups: annuals and perennials. An annual grass is a grass that grows year after year.
A perennial grass grows for a short period of time, usually less than a year, and then dies. Some species of grass are also classified as biennial, meaning that they can grow for more than one year in a row. Biennials are the most common grass types in the U.S. and are found on almost every continent except Antarctica. They can also be found throughout the tropics and subtropics of the world.
How far down do you cut ornamental grass?
Warm-season grasses taller than three feet should be cut back to four to six inches from ground level. Shorter mature plants can be trimmed back to three inches. The cool-season grasses should be back by one to two inches each year.
Do not apply fertilizer in the spring or early summer, as it can cause damage to the lawn during that time. If you do not have a lawn mower, you can use a garden hoe to mow lawns.
Should you cut down ornamental grasses in the fall?
Some people prefer to cut these grasses back in the fall as they don’t like the floppy look during the winter, but the foliage helps to insulate the crown of the plant. We recommend you wait until late winter or early spring to cut them back.
If you have a large lawn, you may want to trim the grass back a bit to make room for your new plants. This will help to keep your lawn looking its best.
Do ornamental grasses spread?
Unlike the tidy growth habit of clump-forming grasses, ornamental grasses that increase by rhizomes will spread, or run, throughout a garden bed and can quickly take over.
Like other turfgrasses, the best way to manage an ornamental grass that runs like clumps is to keep it away from the edge of your lawn. You can also use a mowing machine to mow away the excess grass.
If you have a lawn mower, be sure to turn it off when you are done.
How do you propagate ornamental grasses?
Split them using two forks inserted back to back in the centre of the clump, and then prize them apart. You can cut the clump through the middle with a spade. It is possible to cut through the tough roots of some grasses with a sharp knife, saw or axe.
Cut the grass into small pieces. Place the pieces on a baking tray lined with baking paper. Cover the tray with plastic wrap and leave in a warm place for at least 24 hours, or up to a week.
