| Sowing Time: | |
December-June
|
|
| Sowing Method: | |
3-5 seeds per plug
|
|
| Germination: | |
14-20 days at 18-21 °C, in media with very low soluble salt levels and pH: 5.5-6.0. Cover seed lightly with vermiculite 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 15-18° 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 150-220 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 will support the young plant quality. For full flowering annual transplant several plants into one pot. Plant cut flowers in 60-80 x 80 cm space and use nets to keep the stems upright.
|
|
| Media: | |
Use a well-drained, growing perennial substrate with 0-15 % clay, 0-15 % organic parts (e.g. bark, wood fibres),1-2 kg/m³ complete balanced fertilizer, 0-3 kg/m³ slow release fertilizer (3-9 months), iron-chelate, micronutrients, pH: 5.5-6.0. Field: sandy, loamy soils with good drainage and good nutrition levels. Standard fertilization: 80-100 g/m² slow release fertilizer.
|
|
| Photoperiod / Light: | |
Short day plants. For flowering short days and for the growth long days are required. Cultivate the plants for 2-4 weeks in long day (14-16 h, 30-50 klx) firstly. When the plants have the desired height, start the short days for flowering. For the flowering minimum 6 weeks, better 10-12 weeks of 8 h are required. For darkening maximum of light level is 3 lx. Start in early spring or winter with assimilation light for good plant quality. Night interruption is possible.
|
|
| Temperature: | |
Grow at 12-15 °C or outdoors. In winter indoors frost free at 3-5 °C or outdoors. At mid December the plants start to grow for 5-7 weeks at 15-18 °C. Cold temperatures at 7-12 °C will increase the cultivation time. Temperatures above 25 °C cause a pre-induction of the flower.
|
|
| Fertilization: | |
High fertilization levels are required. Fertilize the crop weekly with 150-200 ppm nitrogen (at 3 kg/m³ slow release fertilizer in substrate), using a potassium balanced fertilizer (N: K2O-ratio: 1:1,5). Avoid high ammonium and high nitrogen levels. Don't fertilize after mid September. In spring fertilize 150-200 ppm nitrogen of a potassium balanced fertilizer. 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 80-100 g/m² fertilizer in several portions yearly. N min soil value: approximately 130 g N/m².
|
|
| Cut Flowers: | |
Cut flower stems can be harvested, when 25 % of the flowers are open. Vase life: 14-18 days. Cold storage is possible. After harvest, cut plants back to the soil level.
|
|
| Cultural Hints: | |
Cut flower production: Control the weed regularly. Keep the soil level open. Remove the plant tops for a better branching and good plant quality. Be aware of Powdery Mildew and Aster Rust in the second half of the crop.

|
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.
