When to Divide Pampas Grass

The best time to divide Pampas grass is in early spring or late fall. However, there are signs to know when you can specifically do the division.

  • When a new Pampas grass plant emerging in spring, it is the best time to divide it. Dividing the parent grass gives space for the younger plant to grow.
    Furthermore, grasses like Pampas do not grow until late spring, so it is best not to divide them until late spring or May. 
  • When the center of the grass begins to clump, it is also the best time to divide it. The excess growth of old grasses causes clump that prevents the growth of new batch of grass.
  • When the Pampas grass have spread too much and invade other nearby plants, it is also the best time to divide it. 

How to Divide Pampas Grass

The process of dividing Pampas grass is a fairly easy task due to its height and large size.
Before dividing it, cut its foliage down to approximately 4-6 inches above the soil level and remove this large plant from the ground.
Here are the procedures on how to divide it properly.

  • Lift grasses from the ground with a spade – use a digging spade to remove a section from the side of the root ball.
    Take a healthy portion from the side of the root ball with at least five shoots and plenty of healthy roots. 
  • Split the grasses using two forks inserted back to back in the center of the clump, then separate them apart.
    Alternatively, cut the clump through the middle with a spade.
  • Repeat the division process until you reach the desired size of plant. As much as possible, remove smaller divisions from the clump by pulling them away from the parent plan

Important Reminders

  • Plant the newly cut grass or plants into the ground as soon as possible.
  • Use a heavy-duty, sturdy shovel with a sharp cutting edge, an axe or a pick (mattock) when digging out the clump of Pampas grass for an easier dividing and lifting extremely-large root balls out.
