How to Grow Pampas Grass from Seed

Overview

While pampas grass is often bought as started plants, growing from seed is economical. Start seeds 3–4 weeks before the last frost for a head start.

Step 1: Prepare Pots

Fill 1/2-gallon pots with standard potting soil. Add 1 inch of gravel at the bottom if no drainage holes.

Step 2: Sow Seeds

Plant 4 seeds per pot, equally spaced, 1/2–1 inch deep.

Step 3: Germination Conditions

Place in a sunny spot (or under grow lights). Water twice daily to keep soil moist 3–4 inches deep. Seeds sprout in ~2 weeks.

Step 4: Reduce Watering

Once sprouted, water once daily, allowing soil to dry slightly between waterings.

Step 5: Transplant

Move seedlings to the garden when they reach 3 inches tall.
