Location

Pampas grass can grow to be quite large, so take this into consideration. Some varieties will grow up to 6 feet tall, and some even larger.

Plant your pampas grass where there is plenty of space, both around the plant and above it. You don’t want it to hit the top of a walkway or grow into the space of other plants.

Your pampas grass will spread out as it grows, so keep about a foot between each plant.

As for sunlight, pampas grass does best with full sun although if need be, you can plant it in partial shade. Take into consideration any nearby structures such as your house, a fence, or a tree, to determine how much shade there will be while growing.

Another factor to consider with pampas grass is that the edges of the blades are quite sharp. You should plant it far enough back from a walkway or where children gather to prevent any unwanted scratches or cuts.

After your pampas grass is established, you only need to water it at the height of summer or if you are in the middle of a heat wave.
