Pampas grass (Cortaderia selloana), which is known for its white feathery plumes, will add a beautiful texture to any outdoor area. It’s increasingly being used for home decorations in wreaths and centerpieces, and has recently even become a popular choice for wedding bouquets. The silvery plume-like flowers are popular both in their fresh and dried forms among flower arrangers and crafters.

It’s quite easy to care for once established, often requiring only yearly pruning. This tough grass can withstand strong winds, extended periods of drought, and the salt spray that comes from coastal areas. What’s best is that it’s also resistant to most plant diseases and pests.

Pampas grass grows fast and can spread quickly. Carefully consider where you want to plant your pampas grass and ask your local greenhouse if they have any sterile plants that won’t self-seed.

Pampas Grass Care

A sunny, well-draining soil is ideal for planting pampas grass. Pampas grass is a low-maintenance plant that requires little watering or fertilizing. You can either choose to buy a plant or start your pampas grass from seed.

Pampas grass plants can be male or female, with the female having more showy plumes. To grow the more desired female plants, the plant is normally propagated by dividing and replanting a clump from a female plant.

This statement plant needs ample space to grow. Pampas grass develops to an average height and width of 10 feet and readily self-seeds. Plus, it can start overtaking other vegetation and be tricky to get rid of once planted.

That’s why, it’s important to think carefully about where to plant it. Also, make sure it’s not listed as invasive in your area before you decide to plant it.

Pampas grass is excellent for concealing items like HVAC systems or unappealing views. However, make sure not to plant pampas grass where it could spread onto your neighbor’s property or anywhere near your home where you don’t want it to block your view. This plant is also highly flammable, so do not plant it near a barbecue grill or other fire hazard.

The leaves of the Pampas grass are razor-sharp. When pruning or working close to pampas grass, use safety precautions like gloves, long sleeves, and pants, and plant it far away from where kids and dogs like to play.

Light

Pampas grass requires at least six hours of sunlight each day and grows best when planted in full sun. In the shade, pampas grass is more prone to fungal diseases and won’t thrive or produce flowers.

Soil

Pampas grass thrives in moist, nutrient-rich soil with good drainage. The ability of the soil to drain efficiently is essential for healthy pampas grass. Compost is an excellent soil amendment for areas with pampas grass because it improves soil quality and drainage.

Water

Pampas grass is quite drought-tolerant, making it an easy plant to care for. Unless there is a severe drought, established plants should get enough water from rain.

Water newly planted plants well right away after planting. You may want to water your grass intermittently for the first several months to ensure that it gets enough water. After that, the plant will receive all the water it requires from natural rains.

Temperature and Humidity

Pampas grass grows well in hot weather. These grasses are native to South America and can handle both heat and high humidity. However, these hardy grasses can also tolerate cold temperatures and even a little snow.

Fertilizer

Pampas grass doesn’t need any fertilizer other than compost, which not only improves the soil but also helps with drainage.

Pruning

By cutting the plant back hard to the ground in late winter, you can keep it under control and help it grow well next year. When pruning pampas grass, make sure you’re wearing protective clothing and eye protection since the leaves are razor-sharp.

How Long Does Pampas Grass Last When Used for Decor?

If handled carefully, freshly cut, dried, and preserved pampas grass may last for two to three years. Keep the grass away from direct sunlight and out of hot or humid areas in your home, such as the bathroom where it won’t last too long as decor.

Every so often, take the plumes outside and give them a light shake to remove any dust that may have accumulated on them. This will also help to fluff up the plumes again.

How To Use Real Pampas Grass for Decoration

Real pampas grass can be dried and used for decorating by first trimming the stalks with a clean cutting tool since the stalks are thick. Next, carefully tie them together with a rubber band, and then hang them upside down in a cool, dark, dry place that has good air circulation for two to three weeks.

If you’ve just cut some fresh pampas grass and want to put the stalks in a vase right away, you can do that too. However, don’t add any water to the vase because pampas grass is a dry grass.

How to Plant and Grow Pampas Grass

How to Grow Pampas Grass from Seed

Since pampas grass may grow up to 10 feet tall and wide when fully grown, consider carefully where you want to plant it.

To start, loosen the soil and directly sow seeds. Avoid covering the pampas grass seeds with a thick layer of soil since it will grow more easily if it has access to light and water. Instead, lightly cover the seeds with well-draining, nutrient-rich soil.

You can prevent birds from eating the seeds by covering them with netting. Germination will typically take approximately three weeks.

Alternatively, you can start pampas grass seed indoors in containers and transplant seedlings outside.

How to Propagate Pampas Grass

Division is a simple and effective method for propagating pampas grass. After pruning the plant to the ground, divide it and its root system with a sharp shovel.

Next, dig carefully around the clump until you can lift it out of the soil. After filling in the hole, move the newly divided plant to its designated spot.

If you plant them near other grasses, space them six to eight feet apart to give them enough room to grow.

How to Pot or Repot Pampas Grass

Though it can grow rather large, pampas grass, particularly the dwarf types, can be easily grown in pots. Due to its size, it is best to select a large container with ample space for growth.

When the pampas grass fills the container, either divide the cluster or transfer it to a larger container. To do this, turn the grass on its side and tap the outside of the pot until the roots come loose.

Place the plant in its new container and fill it with rich, well-draining soil. Make sure there are drainage holes in the bottom of the pot to prevent water from collecting.

Common Pests and Plant Diseases for Pampas Grass

Pampas grass is generally resistant to most plant diseases and pests. However, if the plant’s tussock or crown gets too big, the plant’s base can get too full and start to rot. If this occurs, the entire tussock must be removed.
