How to Start Pampas Grass From Seed


The pampas grass plant may not grow noticeable flowers, but its massive seed heads--the top stalks that can grow 10 feet or taller--are just as showy as many ornamental flowers. Though you can buy started pampas grass plants from many garden stores, starting the plant from seeds can be cheaper. Start germinating the seeds three to four weeks before the last frost date in your area to get a head start on the growing season.

Step 1

Fill 1/2-gallon plant pot with standard potting soil. If the pot doesn't have drainage holes on the bottom, pour an inch of gravel at the bottom of the pot before adding the potting mix.

Step 2

Bury four pampas grass seeds into the potting soil with each seed equally spaced from the other. Each seed should be buried 1/2 inch to 1 inch deep.

Step 3

Place the pot in a sunny area, such as near a window or outside on a patio if there is no danger of frost. Water the potting soil twice a day or as needed to keep the potting soil moist to a depth of 3 to 4 inches. The seeds will typically germinate and sprout within two weeks.

Step 4

Reduce watering sessions to once a day when the seeds have sprouted. This gives the potting soil time to dry out slightly between waterings.

Step 5

Transplant each seedling into your garden once the pampas grass seedlings have grown to a minimum height of 3 inches.

Tips and Warnings

  • When mature, the leaves of the pampas grass are sharp and can cut you when you're handling the plant. Take precautions by wearing gloves and long-sleeved shirts.
