PINK / WHITE PAMPAS GRASS SEEDS
Growing & Care Guide.

QUICK FACTS

Botanical type: Pampas Grass (Cortaderia selloana)

Light: Full sun preferred (partial shade is OK)

Germination: 10–21 days (may take up to 4–6 weeks)

Bloom time: Usually 1–2 years from seed

Height/Spread: 5–10 ft (1.5–3 m) tall and wide

Soil: Well-draining, sandy/loamy soil

Water: Moderate until established, drought-tolerant after

1) WHEN TO PLANT

Indoors (recommended): Start seeds 8–10 weeks before your last frost.
Outdoors: Sow in spring after frost danger has passed.

2) HOW TO START SEEDS INDOORS

You will need a seed tray or small pots, seed-starting mix, water sprayer, and bright light.

Fill tray/pots with moist, light seed mix (not soggy).

Surface sow seeds on top of soil. Pampas seeds need light to germinate.

Do not bury deeply.

Optional: dust with a very thin layer of soil/vermiculite.

Mist gently to settle seeds.

Cover with a clear lid/plastic wrap (keep humidity high).

Place in a warm, bright spot:

Temperature: 68–77°F (20–25°C)

Light: 12–16 hours/day (sunny window or grow light)

Keep soil evenly moist by misting or bottom watering.

Tip: If mold/algae appears, remove cover for a few hours daily for airflow.

3) TRANSPLANTING SEEDLINGS

When seedlings have 2–3 true leaves:

Move into individual pots with well-draining potting soil.

Water when the top 1 in (2–3 cm) of soil feels dry.

Feed lightly every 2–3 weeks with half-strength balanced fertilizer.

4) HARDENING OFF & PLANTING OUTDOORS

After last frost and when nights stay above 50°F (10°C):

Hardening off (7–10 days):
Gradually increase outdoor time and sun exposure each day.

Planting steps:

Choose a full-sun, well-drained location.

Dig a hole twice the pot width. Plant at the same soil level.

Space plants 3–6 ft (1–2 m) apart.

Water deeply after planting.

5) CARE AFTER PLANTING

Light:

Full sun (6–8 hrs/day) gives best growth and plumes.

Water:

First 2–3 months: water deeply 1–2 times/week.

After established: water only during long dry spells.

Avoid waterlogged soil to prevent root rot.

Soil:

Pampas grass dislikes heavy clay. Improve drainage with sand/compost or plant on a slight mound.

Fertilizer:

Feed lightly in spring with compost or slow-release balanced fertilizer.

Too much nitrogen = lots of leaves, fewer plumes.

6) PRUNING & WINTER CARE

Pruning: Late winter/early spring

Tie leaves into a bundle.

Cut back to 8–12 in (20–30 cm) above ground.
Wear gloves & long sleeves—leaves can be sharp.

Cold areas:
Mulch around the base in late fall. In very cold climates, grow in large pots and shelter over winter.

7) TROUBLESHOOTING

No plumes yet: Plant may be young (often blooms year 2), needs more sun, or was over-fertilized.

Yellowing / soft base: Too much water or poor drainage → reduce watering, improve soil drainage.

Flopping leaves: Not enough sun or too much fertilizer → move to brighter spot, feed less.
