Landscape/bedding plants, mixed containers, hanging baskets
1-2 seeds/pills per plug
Stage I: 3-5 days at 72-75 °F (22-24 °C); use well drained media with low soluble salt levels and pH 5.5-5.8. Requires light for germination. Before sowing treat the substrate with fungicide. Water adequately after sowing to completely dissolve the pellet. Don’ t cover seed. Keep soil very wet for optimal germination. Supplemental lighting (100-500 lx) during germination promotes a uniform germination and improves a compact plant habit
5-6 weeks after sowing transplant 1 plant in packs or pots 9-10 cm (3,5-4’’) or 4 plants in baskets.
Use a well-drained, growing substrate with 15-30 % clay, 1,5-3 kg/m³ complete balanced fertilizer, 0-3 kg/m³ slow release fertilizer (3-6 months), iron-chelate, micronutrients, pH 5.4-6.0.
Grow at 14-16 °C (57-61 °F). For early selling the plants should be hardened at 10-12 °C (50-54 °F) slowly within 14 days. Temperatures below 10 °C (50 °F) will inhibit the growth and can lead to injuries on a long-term basis. Petunia does not tolerate frost.
High fertilization levels are required. Fertilize the crop weekly with 150-200 ppm nitrogen, using alternating a potassium balanced fertilizer (N: K₂O-ratio: 1:1,5) and a calcium nitrate fertilizer. Prevent magnesium deficiency by applying magnesium sulphate (0,05 %) 1-2 times and in case of iron deficiency (yellow leaf edges) apply iron-chelate for 1-2 times. Avoid high fertilizer concentrations, it is advisable to fertilize several times weekly with low concentrations. This will promote a constant growth.
