|
|
| Sowing Time: | |
Pot plant production: February-May; Outdoors forcing: April-May (frost free)
|
|
| Sowing Method: | |
2-3 seeds per plug, can be sown directly into field
|
|
| Germination: | |
5-8 days at 20 °C in media with low soluble salt levels and pH: 5.5-5.8. Cover seed with vermiculite, sand or substrate after sowing. Keep soil slightly moist but not wet.
|
|
| Plug Culture: | |
From Stage II reduce the soil moisture, but the plug should not dry out and reduce the temperature to 17-18 °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 100-150 ppm.
|
|
| Growing On: | |
4-5 weeks after sowing transplant 1 plant per plug tray (3-4 cm) and 4 weeks later transplant 1 plant into a pot (8-10 cm), 2-4 plants into a bigger pot (10-15 cm) or a container (3-5 l). Two time transplantation for cut flower production is recommended. Plant cut flowers in 30x30 cm space.
|
|
| Media: | |
Use a well-drained, growing substrate with 20-30 % clay, 1-2 kg/m³ complete balanced fertilizer, iron-chelate, micronutrients, pH: 5.5-5.8. Field: loamy soils with good drainage and good nutrition levels. Standard fertilization: 50-60 g/m² slow release fertilizer.
|
|
| Temperature: | |
Grow at 15-18 °C. In winter indoors frost free at 3-5 °C or outdoors. In spring start to grow at 15-18 °C. Cold temperatures at 7-12 °C will increase cultivation time.
|
|
| Fertilization: | |
Moderate fertilization levels are required. Fertilize the crop weekly with 100-150 ppm nitrogen, using a complete balanced fertilizer. Avoid high ammonium and high nitrogen levels. Field: If necessary according to analysis, improve the soil with 10-20 g/m² fertilizer. N min soil value: approximately 60 g N/m².
|
|
| Cut Flowers: | |
Cut flower stems can be harvested, when the first of the head flowers is open and the stem stability is good. Vase life: 7-10 days. Cold storage is possible to a limited. Cut the flowers not too deep, so that new shoots can be grown.
|
|
| Cultural Hints: | |
Dry, light and airy cultivation. C. bipinnatus does not tolerate over watering and should be watered carefully.
|
|
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.
