Hibiscus Seedlings Leggy and Curling – Lower Temperature

Seedlings at 2-Leaf Stage, 75–80°F Under Lights

Leaves curling, stems weak. Germination was good.

Hibiscus seedlings have high light needs and get leggy in warmth. Move to 65°F (18°C) to slow growth and strengthen stems.

After last frost, harden off 10 days in sheltered spot. Plant deep to bury leggy stem (works for tomatoes too).
