You can often find the tip on the Internet that pampas grass spreads very much and should therefore only be planted with a root barrier. Here the ornamental grass is obviously confused with other plants such as bamboo or reeds, which spread through rhizomes in the garden.

Pampas grass does not form rhizomes

Pampas grass does not form clumps of rhizomes

In contrast to bamboo or reeds, pampas grass is a plant that forms a clump. By this, the gardener understands a central bush of grass that increases in size over the years.

The new branches sprout in the middle of the clump and push the old ones aside. As a result, the eyrie increases in size and can easily reach a meter in diameter.

Pampas grass does not form rhizomes with which it can spread throughout the garden. The creation of a rhizome barrier is therefore superfluous.

Simply cut off clumps that are too large

Over the years, the clump of pampas grass can become very large. Sometimes it also starts to rot inside. To reduce the size of the pampas grass, simply prick off the clump on the sides. You don't even have to dig up the whole rootstock, just uncover something on the side.

You can use the resulting root pieces very well for propagation. As long as there are at least two eyes, the roots will reliably sprout again in a new location.

If the pampas grass is rotten in the middle, that is no reason to remove the ornamental grass from the garden. Divide the eyrie so you can pick out the rotten parts. Place the remaining pieces next to the terrace as privacy screens or give them away to the neighbors.

Alternative: grow pampas grass in a bucket

If you fear that the pampas grass will overgrow too much, you can also grow the ornamental grass in the bucket. It then only needs more care:

  • water more often
  • fertilize regularly
  • winter frost-free

However, since the space in the bucket is cramped, you have to expect that the pampas grass will not form fronds.

tips

The inside of the nest does not tolerate moisture at all. This is especially a problem in winter. Pampas grass is therefore not cut in the fall, but tied together at the top.
