How to grow Beacon Formula Mix Impatiens seeds

Choose Your Planting Method

• Indoors: Start indoors 8-10 weeks before the last frost.
• Outdoors: Transplant outdoors only after all frost danger has passed and nights stay above 50°F (10°C).

Prepare Your Materials

• Seed-starting trays or pots (if indoors)
• Well-draining potting mix
• Clear plastic wrap or humidity dome
• Spray bottle for misting

Sowing the Seeds

• Surface sow — press seeds gently into moist mix and do not cover; impatiens need light to germinate.

Provide the Right Conditions

• Light: Bright light for germination; grow seedlings in bright, indirect light.
• Temperature: 70-75°F (21-24°C).
• Humidity: A humidity dome keeps the tiny seeds from drying out.

Germination

• Seeds generally sprout within 7-14 days.
• Remove the cover at the first sign of sprouting and keep the mix evenly moist.

Transplanting

• When seedlings have 2-3 sets of true leaves
• Harden off gradually before planting out
• Space 8-10 inches apart

Care Tips

• Sun: Partial to full shade; morning sun with afternoon shade is ideal.
• Water: Keep soil consistently moist; do not let plants wilt.
• Fertilizer: Feed lightly — heavy feeding can delay blooming.

Bloom Time:

Late spring to the first frost.
