Sunflower Seedlings: 4-Inch Pots, Full Sun, Dry-Down, Plant Outdoors ASAP

Your $1 Target sunflower kit sprouted 2.5" in 3 days. They need immediate upgrading.

Immediate Steps

1. Each seedling → own 4-inch clay pot with saucer
2. Soil: Cheapest potting soil + extra perlite (2:1 ratio)
3. Light: Sunniest south window (full sun)
4. Water: Empty tray after watering. Dry nearly completely before next.

Outdoor Transition (Critical)

• As soon as nights >50°F: PLANT IN GROUND
• Sunflowers are outdoor plants—pots are temporary
• They'll dwarf any container

Care Level

Easy IF given sun + drainage + outdoor life. Hard/impossible as long-term houseplants.

Your fast sprouts show good viability. Get them outside and they'll tower!
