The root system of pampas grass, called Horst, becomes very large and sprawling over the years. Often the plant begins to bare in the middle. By dividing the root, pampas grass can be kept in check and rejuvenated. At the same time you can multiply new perennials for the garden.

Propagate pampas grass by division
While pampas grass can also be propagated by seed, this method is not particularly ideal. For one, you don't know what properties the new plants will have, especially if you collected the seed yourself. On the other hand, rearing from seeds is tedious and expensive.
It is easier to dig up all or part of the pampas grass in the spring, cut off pieces of root and put them back in the desired location.
Rejuvenate large perennials by dividing
The older the pampas grass gets, the bigger the eyrie gets. So that the ornamental grass does not spread too much, you should reduce the eyrie from time to time by dividing it.
With old perennials, the new shoots in the middle become weaker and weaker. You can rejuvenate such plants by digging them up and cutting out the middle with a spade, hatchet or saw.
The remaining root pieces are divided and replanted in tubs, as a privacy screen or as a single plant.
The best time for dividing pampas grass
Most experts recommend digging and dividing pampas grass in the spring. Then the perennial has enough time to prepare for the cold season.
You can also divide the ornamental grass in autumn. But then you have to ensure good winter protection so that the perennial does not freeze to death in sub-zero temperatures.
How to divide a pampas grass perennial
- Dig up all or part of the root
- Cut the middle with a spade
- cut off or saw off pieces of large clumps
If the pampas grass is to be propagated by dividing it, divide it into individual pieces at least the size of a man's fist. At least two eyes must remain on each section so that the ornamental grass can sprout again.
tips
If you want to permanently remove the pampas grass from the garden, divide the root ball into individual pieces. This makes it easier to get the ornamental grass out of the ground.
