Pampas Grass Background and Description

Pampas Grass originally hailed from the Pampas region – hence the name – of southern South America. During the 70s it became widely used as an ornamental grass to be harvested and used for decorative purposes once dried – and it is back trending once again!

When is Pampas Grass In Season

In Australia, Pampas Grass blooms from Summer to Autumn (from September through to February) but is widely available all year. Once taken from the garden and put into a vase, it has a life expectancy of three years.

How to Grow Pampas Grass

  • Before growing your Pampas Grass, we recommend referring to our Checklist on how to grow Pampas Grass –
  • Ensure you have chosen to plant in an area with plenty of room to grow (this is particularly important when planting multiple plants).
  • If mass planting pampas grass, distance them by 6-8 feet.
  • Full sun is optimal but partial sun is OK.
  • Moist, well-draining soil is preferred.
  • Avoid planting in cold regions unless growing in pots and brought indoors over winter.

How to Care for Pampas Grass

The great thing about caring for Pampas Grass is that it is easy! It really doesn’t need much attention (except for watering in extreme drought) and pruning each year to the ground. Pruning is best executed in late Winter and we recommend using appropriate safety gear as Pampas Grass has sharp foliage. There is also an alternative option to burn the foliage (don’t worry it doesn’t hurt the plant) down to the newest growth.

How to Propagate Pampas Grass

As with most plants, Pampas Grass is typically propagated through division in Spring. Slice through its pruned clumps with a shovel and then replant to your liking! Female plants are the preferred propagation choice as they are more common among varieties grown AND they offer a better aesthetic with fuller plumes (flowers) of silk-like hairs.

  • We recommend following these steps when propagating your Pampas Grass –
  • Cut the grass back 1-2 feet in length, aim to see the plant’s base.
  • Check the stems of the grass at soil level, you should see that shoots are forming at the base.
  • Cut away the new growth from the middle of the plant (Tip: use a sharp knife here).
  • Plant your new grass clumps at a similar depth to what they were used to with the mother plant.
  • WATER THOROUGHLY to limit transplant shock
  • Always make sure you wear safety gear (such as gloves and a long-sleeve shirt) to avoid cutting yourself on the grass’ sharp edges.

Pests and Diseases to watch out for with Pampas Grass

As an invasive species, Pampas Grass is not eaten by any animals. However, insects and birds often nest in Pampas Grass so care should be taken when propagating in the early Springtime.

Watch out for spots on your Pampas Grass during the wet season as this is a type of fungus infection. Treat it with a general plant fungicide as soon as you notice any spots appear.

Pampas Grass Ornamental and Decorative Purposes

Ornamentally, Pampas Grass can feature as a windbreaker on beach-front properties, it can help create privacy (due to its height) and the large plumes of flowers create a fantastic focal point for any landscape.

Pampas Grass arrangements have become very popular within the home too, lasting up to three years in vases and providing an ethereal impact. A great alternative to fresh flowers, once the plumes are conditioned, they require no maintenance at all!

Overwintering Pampas Grass

While Pampas Grass prefers a warmer climate, with adequate preparation it can survive the colder months too. Trim your Pampas Grass in the weeks leading to Winter to allow for new growth in the following season.

Be sure to remove any stalks over 1-foot tall (tip: string the plants together prior to trimming) as this will assist in draining water within the plant. If you live in a warmer region (such as QLD) you can overwinter your Pampas Grass.

To add extra protection from the cold spread mulch around the base and cover it with a burlap and remove the burlap once the weather warms again. This allows the roots of the plant to stay warm and dry during Winter and sets them up to thrive in Summer.
