|
| Sowing Time: | |
January-February for flowering in pots from May onwards; July-August for flowering in pots in the following year
|
|
| Sowing Method: | |
1-3 seeds per plug
|
|
| Germination: | |
12-16 days at 15-20 °C, in media with low soluble salt levels and pH: 5.5-6.5. Cover seed with vermiculite, sand or substrate after sowing. Keep soil slightly moist but not wet. High temperatures above 23 °C will inhibit germination.
|
|
| Plug Culture: | |
From Stage II* reduce the soil moisture, but the plug should not dry out. 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 up to 100-150 ppm.
|
|
| Growing On: | |
4-6 weeks after sowing transplant 1 plant per plug tray (4x4 cm) and 4-6 weeks later transplant into a pot (9-12 cm) and 3 plants into a bigger pot (13-15 cm) or into a container (3-5 l). Take care of hypocotyls. Transplant the plant not too deep in substrate. After transplanting keep the tray, because it is possible that more seeds germinate at a later time.
|
|
| Media: | |
Use a well-drained, growing substrate with 10-30 % clay, 0-15 % parts (e.g. bark, sand, perlite), 1-2 kg /m³, complete balanced fertilizer. 1-2 kg/m³ slow release fertilizer (3-9 months), iron-chelate, micronutrients, pH: 5.5-6.5.
|
|
| Photoperiod / Light: | |
Day length neutral plant. Flowerings pot production in winter and spring with additional assimilation light will improve the plant quality.
|
|
| Temperature: | |
Grow at 10-16 °C. In winter indoors frost free at 3-5 °C or outdoors. Outdoor fleece cover and dry substrate needed. In spring the plants start to grow for 7-9 weeks at 12-16 °C. A chilling period for flower initiation is not required. For good growth and proper branching the temperatures should be above 10 °C.
|
|
| Fertilization: | |
Moderate fertilization levels are required. Fertilize the crop weekly with 100-150 ppm nitrogen (at 2 kg/m³ slow release fertilizer in substrate), using a complete balanced fertilizer. Avoid high ammonium and high nitrogen levels. 3-4 weeks before flowering using a potassium balanced fertilizer
(N: K2O-ratio: 1:1,5). Don't fertilize after flowering or after early September. In spring fertilize with 100-150 ppm nitrogen using a complete balanced fertilizer. 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. Avoid high fertilizer concentrations, it is advisable to fertilize several times with low concentrations weekly.

|
| Cultural Hints: | |
Grow rather dry and avoid wetness in substrate. The roots are very sensitive too wet substrate. Don't produce too close, because the flowers stems package for selling break off easily.
|
|
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.
