How Long Does It Take For White Pampas Grass To Grow?
White pampas grass Cortaderia selloana is a very fast grower, and a plant can go from pampas grass seeds to producing seeds of its own in 2-3 years. They germinate in the spring and can start producing pampas grass seeds in their second year of full sun. The pampas grass seeds production leads to a host of other problems though, which will be explained later.
The Danger Of Pampas Grass
Pampas grass Cortaderia selloana is not illegal in most parts of the United States, but it is illegal in Hawaii, South Africa, and New Zealand due to it becoming an invasive species. All pampas plants are able to put out over 1 million pampas grass seeds in their lifetime, then they reproduce and spread those seeds quite fast. All of those new pampas grass seeds grow and spread their own million seeds, and so on.
With all of these pampas grass seeds growing about, the local wildlife and plants get overwhelmed as the newcomer seeds and plants start to hog all the resources. Eventually, the local plants start to die out because of the sheer number of pampas grass sprouts growing around them. They are an invasive species, one that will quickly grow out of control if their growth is not tempered, and that’s why certain states in the United States have banned them.
How to Control Pampas Grass in Your Garden
There are several chemical and natural ways to prevent pampas grass and pampas grass seeds from overtaking your garden, but you need to be vigilant as long as you have pampas grass in your yard. Pampas grass leaves are sharp enough to cut skin and lead to infections, so you should always wear long-sleeve clothing and gloves to deal with them.
For smaller clumps of grass, grab them and jerk the entire plant out of the ground, while also making sure to take out the root system. Place all of the removed plants into a bag and then put them in the landfill. Make sure to catch any seeds that fall!
If you have larger clumps of pampas grass that are more than three feet in height, you will need to use shears to cut them down to about two feet and then spray the stalks with a ready-to-use herbicide. Then, repeat the spraying process every single week until the plants are gone. Place the cut parts of the plant into a bag and send those to your landfill.
If you are using herbicides, make sure to keep the spray away from healthy plants in your garden that you don’t want to get harmed.
For a less permanent way to slow down the growth of pampas grass, head out into the garden and look for the seeds that have been shed by the parent plant. Pick the seeds up and dispose of them, and they won’t grow into new grass shoots.
It typically takes around two to three weeks for pampas grass seeds to germinate, provided they are planted in well-draining soil with proper moisture and temperature conditions.
The number of pampas grass seeds to plant depends on the size of the area you want to cover with pampas grass. As a general rule, you should plant 2-3 pampas grass seeds per planting hole or per square foot of planting area. This will ensure that you have a good chance of at least one seed germinating and growing into a plant. However, keep in mind that pampas grass can grow very large, so you should allow enough space between each plant to accommodate their full size.
The best time to sow pampas grass seeds is in the spring, after the last frost date in your area. Pampas grass seeds need warm soil temperatures to germinate, so planting them too early in the season may result in poor germination rates. You can also sow pampas grass seeds in the fall, but make sure to do it at least 8-10 weeks before the first frost date in your area so that the seedlings have enough time to establish themselves before winter sets in.
Respecting Pampas Grass
Pampas grass (Cortaderia selloana), is a beautiful flower that can really look good in your garden, but it can quickly get out of control if you don’t take steps to curtail it. Do your best to stop the grass from growing out of control once it starts to produce its seeds, and you can be ready to have this unique plant in your yard.
