Ornamental grass growth will depend on the variety incorporated into the landscape design but can be broken down into two distinct branches: warm season grasses and cool season grasses.

Growth Habits of Ornamental Grasses in General

Even small ornamental grasses need plenty of space to grow and establish firm root systems. Even when planted carefully, these grasses can grow and propagate quickly, leading to crowding in the garden bed. At the first sign of crowding, separate the plants. Gently dig the roots up and transplant the grass to a new area of the garden bed with a similar soil composition. Once established, ornamental grass will grow between 4 to 8 inches per year, depending on the soil conditions and the variety planted.

Cool Season Grasses

Cool season ornamental grasses do best in cooler climates with moist soil. These varieties are sturdy plants that often grow and maintain their color year-round. Since they thrive in cool temperatures, many cool season grasses stay green even during the winter, provided the periods of frost and freezing weather are minimal.

Cool season grasses can be drought tolerant with a little additional help and care. During dry periods, the grass will continue to grow as long as it is sufficiently watered. Should the soil become too dry, the grass will dry and brown, lying dormant until conditions improve.

Unlike warm season grasses, these varieties must be planted with care to avoid overcrowding. Should growth become too thick, the soil may not provide enough nutrients to the plants, leading them to go dormant until the nutrients return to optimal levels.

If the plants go dormant and some of the blades turn brown, the damaged area can be cut away. This encourages the plant to produce fresh, healthy blades during the growing season while keeping the design looking nice throughout the year.

Warm Season Grasses

Warm season ornamental grasses are those that thrive in warmer conditions. These varieties tend to start growing in the mid-to-late spring when soil temperatures increase and wintery days are few and far between. Warm season grasses do best in southern climates where temperatures are mild year-round.

Warm season grasses prefer warm, dry soil and can be successfully grown in the Transition zone where the climate changes throughout the year. For landscape designs in this area, the ornamental grasses may not produce much visible growth until summer is in full swing, but as long as temperatures stay warm, the grasses can thrive, creating beautiful growth until late fall. Once the temperatures drop, the grass turns brown and can be cut back until spring.

It’s important to note that warm season grasses may not produce much noticeable growth until the temperatures in the soil are stable. For most areas, this happens in full summer, so warm season ornamental grasses start showing visible growth later into the growing season. If it’s important to have ornamental grasses that produce visible growth throughout more of the year, it may be possible to combine both cool and warm season varieties.

Planting Ornamental Grasses

Planting ornamental grasses requires some care and prep work to see the ideal growth and production rates, regardless of the types of grass used. As perennials, the grasses should come back, year after year, but their performance and longevity are primarily based on the foundation of the landscape design.

Preparing the Soil

Plants won’t grow in soil that is too densely packed, and tall ornamental grasses are no different. Before planting seeds or starter plants, the soil must be tilled. Tilling breaks up otherwise tightly packed areas, adding air to the soil and exposing nutrients that the plants need to thrive. Tilling can be done either in spring or fall, depending on the planting schedule.

For best results, the soil should be mixed with a small amount of fertilizer and compost to give the grasses the best foundation possible. Once the soil is rich in nutrients, the plants will be able to establish firm roots and produce fresh growth each year.

Most successful landscape designs plant ornamental grasses either in the spring or the fall. Planting in the spring gives each plant the chance to develop a healthy root system capable of surviving the harsh conditions of winter.

These plants are more successful than those planted in the fall because they’re more established in the garden by the time the temperatures drop. Spring planting should be done as soon as the soil is soft enough to work. Tilling through frozen soil is difficult and may only impede the plant’s growth cycle.

Planting ornamental grasses in the fall can be done, but it will require some additional work to keep the perennial plants happy throughout the winter. Since they’re planted late in the season, the root system each plant establishes will be slightly weaker than those planted in spring.

To combat this, make sure the soil maintains a stable moisture level and cover the top layer with mulch when the weather cools down. This will keep the roots warm while they work to establish a strong network.

August and early September are the best times for Autumn planting. Planting in late summer and very early fall gives the new ornamental grasses a chance to establish root systems before the temperatures change and winter weather rolls in. The longer the plants have to adjust to the soil, the stronger their foundation will be and the less damage they’ll suffer during the colder months.

Avoid planting tall ornamental grass starters too deep in the soil. If new plants are started too deep in the garden bed, the roots will not be able to maintain an ideal moisture level and may struggle to absorb the nutrients the plant needs from the soil. In many areas, this results in root rot, mold, and other fungi that damage the growth of the plant. Each variety will have its recommended depth guidelines to ensure ideal growing conditions.

Care and Maintenance

Like all plants, ornamental grasses benefit from conscientious maintenance and care throughout the year. When properly maintained, both cool season and warm season grasses will provide any landscape design with unique, eye-catching growth year after year.


While other plants in the design may benefit from heavy fertilization, ornamental grasses require very little fertilizer to produce new growth. Most varieties do best in low nitrogen soils, and adding too much fertilizer can increase the nitrogen to the point of damaging the plant. For most gardens, using about a quarter cup of fertilizer per plant is sufficient to give the bed the nutrients it needs without harming the chemical composition of the soil. For best results, fertilizer should be applied at the start of the growth season.


Too much water can kill any type of ornamental grasses. While the soil should be moist enough to keep the roots hydrated, it’s best to avoid overwatering the garden bed. Ornamental grasses do not require frequent watering once they’re established, though, during droughts and dry spells, they may need a bit of additional water to maintain their growth.

Water the plants if they show signs of browning leaves and be sure to monitor moisture levels throughout the growing season. Younger plants will need additional water to establish a good root system.

Controlling Weeds

Ornamental grasses may be hardy, but weeds can choke their growth as easily as any other plant. Remove weeds periodically to keep each plant happy and growing strong throughout the year. Avoid the use of chemical weed killers as many of these products destroy grass as well as weeds.

Seasonal Tasks

Ornamental grasses are perennials, so they go dormant during the winter. Their growth gradually turns brown and dries out, leading many people to believe that the plants have died.

While other plants require pruning or removal once they are completely brown, ornamental grasses can largely be left alone during the winter. In fact, the plants only need trimming in the early spring before their growth cycles start. This helps remove any truly dead growth and stimulate the plant into producing new blades.

During the early spring and summer months, the grass needs minimal attention and care. Most plants can benefit from trimming of dead growth and occasional transplanting, should the bed become too crowded.

If plants need to be relocated, it’s best to transplant them in the early spring, so the roots have a chance to develop throughout the full growing season.


Dying plants or those with brown growth in the middle of the plant can even be divided to encourage healthy growth. After the growing season, split the plant in two, cutting away the brown area to improve the appearance of the plant.

Not only will the landscaping look better, but the plant will be able to produce new growth the following season.

Ornamental grasses provide long-lasting and unique groundcover in every landscape design. Select the right variety for the climate and enjoy the foliage year after year.

With proper care and maintenance, ornamental grasses are the perfect accent to any landscape design and garden.
