🌱 Sunflower Seedling Characteristics

1. Cotyledons (Seed Leaves):

   • The first two leaves that appear.

   • They are oval and not the same shape as mature sunflower leaves.

   • They help provide energy from stored nutrients in the seed.

2. True Leaves:

   • Appear after the cotyledons.

   • Typically heart- or spade-shaped with serrated edges.

   • Arranged alternately on the stem.

3. Stem (Hypocotyl):

   • The early stem grows upward and thickens to support the plant.

   • Sunflower seedlings tend to grow fast and can become leggy without enough light.

4. Root Development:

   • A strong taproot forms early and digs deep to anchor the plant and absorb water.

🌻 Care Tips for Sunflower Seedlings

• Light: Needs full sunlight—at least 6–8 hours a day.

• Water: Keep the soil moist but not soggy.

• Temperature: Warm temperatures (65–75°F / 18–24°C) promote growth.

• Spacing: If planting outdoors, thin seedlings to avoid crowding.
