| Sowing Time: | |
March-April for flowering in pots from end of May onwards; June-August for flowering in pots the following next year
|
|
| Sowing Method: | |
1-3 seeds per plug
|
|
| Germination: | |
4-8 days at 20-21 °C, in media with very low soluble salt levels and pH: 5.5-6.0. Requires light for germination. Cover seed lightly with vermiculite after sowing. Keep soil slightly moist but not wet. Avoid direct sunlight by shading seeds after sowing.
|
|
| Plug Culture: | |
From Stage II* reduce the soil moisture, but the plug should not dry out and reduce the temperature to 18-20 °C. Do not let soluble salt level rise above 0,75 EC. Start fertilization at 50-75 ppm nitrogen in a well balanced formula. During Stage III and Stage IV fertilization levels can be increased to 150 ppm.
|
|
| Growing On: | |
4-6 weeks after sowing transplant 1 plant per plug tray (3-4 cm) and 4 weeks later transplant 1 plant into a pot (10-15 cm). Two time transplantation will support the young plant quality. Transplant the plants not too deep into substrate. Plant cut flowers (frost free) in 25-25 x 35-40 cm space or transplant 3-4 plants into a container (25-40 l). For cut flower production cultivate in container in order to simplify culture control because of the container's mobility. Use nets to keep the stems upright.
|
|
| Media: | |
Use a well-drained, growing substrate with 15-30 % clay, 0-20 % parts (e.g. perlite, coconut fibres), 1-1,5 kg/m³ complete balanced fertilizer, 1-3 kg/m³ slow release fertilizer (3-6 months), iron-chelate, micronutrients, pH: 5.8-6.5. Field: loamy, sandy humus soils with good drainage.
Standard fertilization: 50-80 g/m² slow release fertilizer.
|
|
| Photoperiod / Light: | |
Long day plant. The long day (12-14 h) supports the flower initiation and flower development. In winter and early spring additional assimilation light is required.
|
|
| Temperature: | |
Grow at 12-18 °C during daytime and at 10-12°C during night or outdoors. In winter indoors frost free at 3-5 °C or outdoors. Outdoor fleece cover needed. In spring the plants start to grow for 7-9 weeks at 12-18 °C. Warm temperatures will decrease the cultivation time.
|
|
| Fertilization: | |
Moderate-high fertilization levels are required. Fertilize the crop weekly with 100-150 ppm nitrogen (at 3 kg/m³ slow release fertilizer in substrate), using a complete balanced fertilizer. Avoid high ammonium and high nitrogen levels. Don't fertilize after mid September. In spring fertilize 100-150 ppm nitrogen of a potassium balanced fertilizer (N: K2O-ratio: 1:1,5). Prevent magnesium deficiency by applying magnesium sulphate (0,05 %) 1-2 times and in case of iron deficiency (above pH 6.0) apply iron-chelate for 1-2 times. Field: If necessary according to analysis, improve the soil with 50-80 g/m² slow release fertilizer, applied in several portions.
|
|
| Cut Flowers: | |
Cut flower stems can be harvested, when first head flower are just fully open and 50 % of the side buds are open. Closed buds fade and do not open. Remove the bottom leaves. Vase life: 10-15 days. Cold storage is possible. In the first year harvest 10-12 stems per plant, in the second year harvest
20-30 stems. Remove spent flower stems to encourage additional flowers.
|
|
| Cultural Hints: | |
Cultivate rather dry, because the roots are very sensitive to wet substrates or soils. Planting in warm and sunny locations. Protect the plants in winter against frost.
|
|
Hint
The cultural recommendations are based on results from trials conducted under Central European conditions. Different conditions in other parts of the world may lead to deviations in results achieved.
