Whether you want a lush, spare or tropical look, fast-growing grass varieties meet the mark.

Rot can be a big reason why ornamental grass turns yellow and dies. Similarly, most ornamental grasses don't need a lot of fertilizer and too much can cause yellowing ornamental grass. On the other hand, a nutrient deficiency can also be to blame for ornamental grass turning yellow.
Dead grass isn't coming back, so you'll need to take steps to regrow your lawn. You can replace the grass by seeding or sodding — or installing a new type of landscaping material such as mulch, rocks or groundcover. You'll need to first remove the dead grass and prep the soil before laying the new sod.
If your plant is dying, it is either planted in an area that got too cold in winter, or it is not getting enough sun, or the right amount of water. Prune back the grass plant leaving a little green growth of if there is some. Dig carefully around the roots and remove the plant from the soil.
Warm-season grasses that are taller than 3 feet should be cut back to 4 to 6 inches from ground level. Shorter mature plants can be cut back to about 3 inches. Prune cool-season grasses back by two-thirds.
Light. Provide full sun for optimal growth. If the plant is in too much shade, the leaf blades can get floppy, but you can provide a stake or even a tomato cage to help prop them upright.
You can use manual or electric hedge clippers or even a chainsaw on a big stand of grass. Tying off above and below the cut with a bungee cord or rope helps stabilize the grass while you cut. Divide after cutting. (Porcupine grass is a type of miscanthus.
Fertilizing Ornamental Grasses. For the best care, fertilize sparely in the spring with a slow-release fertilizer such as 3-1-2 or 4-1-2 ratio. NOTE: This is part 6 in a series of 10 articles.
It's natural for grass to go dormant to conserve water during periods of limited rainfall, and drought-induced brown grass should turn green on its own as the weather cools and rainfall increases. You can also restore your lawn by giving it an inch of water on a weekly basis with your lawn sprinkler.
Ornamental grasses may be annuals or perennials; short or tall; spring or fall flowering; prolific self-seeders or sterile; invasive spreaders or well-behaved clump-formers. They add two elements to the the garden that are not provided by many other plants: movement and sound.
In mid-Summer, the foliage develops distinctive golden horizontal bands. In Autumn, silvery-white plumes appear and last up to two months. Grows 4 - 7 feet tall and spreads 3 - 5 feet.
Zebra grass normally is a hardy perennial that will return year after year, but like any plant, it might not grow again if it sickens due to diseases or adverse environmental conditions.
Animal Potential
The American Society for the Prevention of Cruelty to Animals states that pampas grass is non-toxic to dogs, cats and horses. Ingesting any type of plant material, however, can cause uncomfortable gastrointestinal symptoms such as diarrhea, depression and vomiting in animals.To propagate and/or revitalize the plant, you can divide it in spring every few years right before or right after the grass blooms or divide the grass clumps when the plant breaks dormancy. Cut the bad roots off before you replant the ornamental grass sections.
Like most deciduous ornamental grasses, zebra grass requires annual pruning for the sake of its health. A good shearing in early spring will rejuvenate this ornamental and ensure tall, elegant fountains of eye-catching striped foliage throughout the entire season.
Occasional division will help grasses remain active and growing and can help renew older grasses. Some grasses, over time, will die out in the center and dividing will rejuvenate the clump. Third Ornamental Grass Rule of Thumb: Divide warm season grasses anytime spring through mid-summer.
You can best transplant and/or divide up the clump in the fall before dormancy or in the spring when the plant is beginning to re-grow.
- Dig out sections of roots to root prune ornamental grasses.
- Dig up the entire clump and slice straight down through the crown with a shovel, separating the original plant into one or more smaller sections for replanting.
- Trim away unwanted growth using garden shears, clipping back leaves like any other plant.
Add additional soil to account for settling, if needed. Once established, tiger grass is moderately drought tolerant, but regular moisture around this plant's roots for the first growing season after planting and during extended dry spells will encourage plant vigor and an attractive appearance.
Pour white vinegar into a spray bottle. Close the lid tightly and shake the bottle to mix the ingredients. Spray the homemade weed killer directly on the ornamental grass. Saturate the entire portion above ground so that the mixture will soak into the root ball and kill it.
In late winter or early spring, these shrubs can be cut all the way back to the ground. Smooth hydrangeas will produce much larger blooms if pruned hard like this each year, but many gardeners opt for smaller blooms on sturdier stems.
However, your kitchen holds a secret weapon to removing this nuisance without herbicides.
- Cut any tall ornamental grass down to within 2 to 4 inches of ground level with pruning shears or scissors.

- Spray the homemade weed killer directly on the ornamental grass.
I suggest cutting your lawn down in a few passes and, if possible, spreading that mowing over a few days. Remove the top layer of grass. Then mow it again one or two days later to get to the desired length. If your grass is like a meadow, try a weed-wacker or scythe to knock it down to size.
Berkeley sedge (Carex divulsa) is a California-native grass that produces thin, evergreen blades and grows in Sunset's Climate Zones 2b through 9 and 11 through 24. Growing to about 2 feet high, this tough plant thrives in various conditions but prefers well-drained soil in full sun or shade.
