|
|
| Sowing Time: | |
Green pots: January- June; Flowering pots: Early August- Mid September for flowering in 8th week.
|
|
| Sowing Method: | |
1-3 seeds per plug
|
|
| Germination: | |
10-14 days at 18-22 °C in media with very low soluble salt levels and pH: 6.0-6.5. 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 16-18 °C. Do not let soluble salt level rise above 0,50 EC. Start fertilization at 50 ppm nitrogen in a well balanced formula. During Stage III and Stage IV fertilization levels can be increased to 100-130 ppm.
|
|
| Growing On: | |
4-5 weeks after sowing transplant 1 plant into a pack or pot 8-10 cm and 3-5 plants into a bigger pot 13-15 cm.
|
|
| Media: | |
Use a well-drained, growing perennial substrate with 0-15 % clay, 0-15 % organic parts (e.g. wood fibres), 1-1,5 kg/m³ complete balanced fertilizer, 0-3 kg/m³ slow release fertilizer (3-9 months), iron-chelate, micronutrients, pH: 6.0-6.5.
|
|
| Photoperiod / Light: | |
Day length neutral plants. Start in spring with supplemental lighting
(30-40 klx) when the temperature rises above 15 °C for good plant quality.
|
|
| Temperature: | |
Grow at 12-15 °C or outdoors. In winter indoors frost free at 3-5 °C or outdoors. Outdoor fleece cover needed. In spring the plants start to grow (from week 51 possible) for 8-10 weeks at 10-15 °C or for 5-6 weeks at 15-18 °C.
|
|
| Fertilization: | |
Moderate fertilization levels are required. Fertilize the crop weekly with 100-130 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 with 130-150 ppm nitrogen of a complete balanced fertilizer.
|
|
| Cultural Hints: | |
A cold cultivation is possible at temperatures 4-5 °C, but the crop time is increasing. In winter at temperatures above 15 °C supplemental light is required for growth stimulating.
|
|
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.
