ZINNIA ELEGANS - Benary’s Giant Series
Sowing Instructions (Cliff Notes version): Germinate at 68-72 °F (20-22 °C). Higher temperatures can reduce germination and cause weak seedlings. Sow seeds in a well-drained media low in nutrients with a pH between 5.8-6.2. Cover seeds lightly with vermiculite.
Growing on: Grow on at 60-65 °F (15-18 °C) for 3-4 weeks. Temperatures below 60 °F (15 °C) delays flowering. Temperatures below 50 °F (10 °C) cause leaves to turn yellow. Zinnia's tolerate high temps of 77 °F (25 °C) but do not tolerate frost. Protect the plants against wind.
Provide good ventilation. Fertilize weekly at 200 ppm nitrogen in a well-balanced mix. Use of calcium nitrate will improve stem strength. For cut flower production, thin seedlings or plant plugs at 8-10" (20-25 cm) in rows or 9-12" x 12" (23-30 cm x 30 cm) spacing in beds.
