The best time to plant pampas grass is in the springtime any time between March and May. However, the most appropriate time is dependent on your geographical area. This is especially the case if you want your pampas grass to grow to a height of 10-feet later in the summer.

Pampas grass doesn’t just offer a striking appearance. It’s also one of the easiest ornamental grasses to grow. However, an element that plays a massive role in how your grass grows is when you decide to plant these grass seeds. Pampas grass is known to thrive in warm temperatures. With that being said, this grass can also be grown in colder zones, but it isn’t going to grow all-year-round and the height potential isn’t going to be the same. 

About the Pampas Plant

Pampas plant, also known as the Cortaderia selloana species, grows to become a flowing and tall feature in the ground that it’s placed when it reaches its full bloom. This pampas grass being grown at the optimal time is going to help it grow to its full potential. When it’s at full potential, it holds the ability to offer effective privacy for your garden. 

How long does Pampas grass take to grow

Pampas grass is a type of long-leafed perennial that can grow up to 10 feet tall, and takes about 3-5 years to reach full maturity. The pampas grass plant prefers full sun and is hardy enough to withstand droughts and other weather conditions. It can take about one year for it to mature enough for people to harvest seeds from it, but this time will vary depending on the climate and soil quality.

When does Pampas grass bloom

Pampas grass blooms in the fall and winter months.
Tall and with long, wispy leaves, pampas grass is a beautiful plant that offers a hint of warmth when the temperatures start to drop. Often found in California and other warm regions, pampas grass is also perfect for colder climates where it can be grown in containers on decks or patios.

Pampas grass is generally planted with full sun exposure and is most at home in hot, dry climates. It has shallow root systems that can make it susceptible to drought if not given adequate water. Pampas grass also grows very quickly and can grow up to 6 feet tall in a single year!

Pampas grass growth stages

Pampas grass is a very attractive ornamental plant. It is also a coarse, erect perennial that can grow up to 10 feet in height. Pampas grass is a robust plant that requires full sun to thrive and grow well. There are 5 stages of growth which can be observed early on in the life of the plant.

The first stage is the seedling stage, which lasts between two and four weeks. The second stage is the tufting stage, which lasts between one and three months. The third stage is the lateral branching stage, which lasts between six and nine months. The fourth state is the maturity or flowering period, which lasts for about one year or until it starts to produce seeds for reproduction purposes. And finally maturation stage that lasts up to 10-15 years before this grass dies off.

Further Considerations:

Along with the time of year that you should be planting this grass, there’s also a variety of other considerations that you’re required to make when planting pampas grass. These include: 

Preparing the Plantation Area

When Lanting this ornamental grass, you’re first going to want to choose ground that’s not going to hinder its size potential or block other greenery. You should clean this ground, as well as work the soil to a minimum of 12 inches in depth. This should be done a few weeks before the planned time you wish to grow your grass. 

Dividing the Existing Plants

Pampas grass grows as a clump-growing pampas grass plant in early spring that’s easy to divide and gain early new growth seedlings. Dividing these plantations in the early springtime offers the best results with root establishment and transplanting. After dividing these roots during the growing season, you should keep it in the soil in a different location at the same 12 inches depth. A recommendation would be to wear gloves when handling this grass as the blades of this grass are sharp and is able to cut your hands.

Beginning from Seed

When planting the pampas plant from seeds, you should start this process during the late winter months. This provides the roots with enough time to germinate and grow into robust seedlings before ultimately transporting these seedlings into an outdoor garden when there’s net growth.
