Zinnia Oklahoma Culture guide

Usage

Plants for bedding, pot plants,by and large beautiful plants, that attract bees and butterflies, cut flower production

Sow time

Indoor forcing: February-March for flowering in pots from July onwards; Outdoor forcing (frost free): End May, can be sown by the time directly into field

Zinnia Oklahoma Sowing method

1 seed per plug to begin with

When to Germinate

7-10 days at 68-72 °F (20-22 °C). Higher temperatures can reduce Sprouting and cause week seedlings. Sow seeds in a well-drained media low in nutrients with a pH between 5.8-6.2. Cover seed lightly with vermiculite.

Zinnia Oklahoma Growing on

Grow on at 60-65 °F (15-18 °C) for 3-4 weeks. Temperatures below 60 °F (15 °C) delays flowering. 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.

Zinnia Oklahoma Media

so far Use a well-drained, growing perennial substrate with 15-30 % clay, 1-1,5 kg/m³ complete balanced fertilizer, iron-chelate, micronutrients, pH: 5.8-6.2. Field: loamy, sandy, humus soils with good drainage. Disinfect the soils in greenhouse or polytunnel before planting. Standard fertilization: 80-100 g/m² of a slow release fertilizer.

Zinnia Oklahoma Temperature

Zinnia Oklahoma Fertilization equally important

Zinnia Oklahoma Moderate feeding levels are required. Of course fertilize the crop once weekly with 100-150 ppm nitrogen, using complete balanced fertilizer. Avoid high ammonium and high nitrogen levels, but high nitrogen levels results in soft stems. Stems that are too soft will break underneath the flower.
Prevent magnesium deficiency by applying magnesium sulphate (0,05 %) 1-2 times and in case of iron deficiency apply iron-chelate for 1-2 times. The roots are sensitive to high salt levels in substrates. Field: N min soil value: approximately 120 g N/m²
