How to grow Phacelia grandiflora seeds

Choose Your Planting Method

• Indoors: Direct sowing outdoors is best, but you can start indoors 3-4 weeks before the last frost.
• Outdoors: Sow directly in early spring as soon as the soil can be worked; in warm climates, fall sowing works too.

Prepare Your Materials

• Seed-starting trays or pots (if indoors)
• Well-draining potting mix
• Spray bottle for misting

Sowing the Seeds

• Sow about 1/8 to 1/4 inch deep and cover lightly; keep covered and out of bright light until sprouted.
• No pre-treatment is needed.

Provide the Right Conditions

• Light: Shade the trays until germination, then move to bright light.
• Temperature: 60-70°F (15-21°C) — phacelia prefers cool soil.

Germination

• Seedlings emerge in 7-14 days in cool, moist soil.
• Keep the soil evenly moist but not soggy until sprouted.

Transplanting

• Move out after the last frost; harden off first.
• Thin or space plants 6-12 inches apart.

Care Tips

• Sun: Full sun to part shade.
• Water: Moderate — let the top inch of soil dry between waterings once established.
• Fertilizer: None needed; phacelia grows well in average or even poor soil.
• Deadhead spent blooms to extend flowering, or leave a few to self-sow.

Bloom Time:

Spring through summer.
