Seed Treatment
Soak seeds in room temperature water for 2–4 hours before sowing.
Best Time to Sow
Late winter to early spring, indoors or in a greenhouse. Outdoors only after the danger of frost has passed.
Germination Time
Up to 6 weeks (42 days), though most seeds germinate within 2–4 weeks under proper conditions.
Optimum Temperature (Day & Night)
Day: 20–24 °C (68–75 °F)
Night: Not below 18 °C (64 °F)
Light Requirements
Seeds require light to germinate. Do not cover with soil. Gently press onto the surface of a moist seed-starting mix.
Sowing Instructions
Use a fine, well-draining seed-starting mix. Mist the surface to moisten, scatter seeds, and lightly press them into the soil. Cover the tray with clear plastic or use a humidity dome to maintain high humidity.
Watering
Keep the soil consistently moist but never soggy. Mist with a spray bottle daily to maintain humidity.
Post-Germination Care
Once seedlings appear, remove any cover gradually to acclimate to normal humidity. Place in a bright location with indirect sunlight. When seedlings develop 2–3 true leaves, transplant into larger pots.
Outdoors Transplanting
Harden off seedlings over 7–10 days before transplanting outside. Choose a sunny location with well-draining soil. Space plants at least 1.5–2 m (5–6 ft) apart.
Notes
- Be patient—germination can be slow and irregular.
- Pampas Grass can grow large; plant where it has space to spread.
- Wear gloves when handling mature plants, as the leaves can be sharp.
