How to grow White Hardy Tall Phlox seeds

Choose Your Planting Method

• Indoors: Sow indoors 6-8 weeks before the last frost; cold-stratify seed in the refrigerator for 4-8 weeks first.
• Outdoors: Sow outdoors in late fall or early spring, which provides natural cold stratification.

Prepare Your Materials

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

Sowing the Seeds

• Sow 1/8 inch deep in moist seed-starting mix.
• If stratifying, mix seed with damp sand in a sealed bag in the refrigerator, then sow and keep at 59-64°F (15-18°C).

Provide the Right Conditions

• Light: Bright, indirect light for germination; full sun to part shade for growing plants.
• Temperature: 59-64°F (15-18°C) after the cold period.

Germination

• Seeds typically germinate in 7-14 days after the cold treatment.
• Grow seedlings on in bright light; they are slow to start but develop steadily.

Transplanting

• Transplant after the last frost, when seedlings have several true leaves.
• Harden off before planting out.
• Space plants 12-18 inches apart for good air circulation.

Care Tips

• Sun: Full sun to part shade in evenly moist, well-drained soil.
• Water: Water regularly; phlox does best when soil stays evenly moist.
• Fertilizer: A light feeding of balanced fertilizer in spring is sufficient.
• Remove spent flower heads to discourage self-sowing; good air circulation helps keep foliage healthy.
