|
| Sowing Time: | |
March-August
|
|
| Sowing Method: | |
3-5 seeds per plug, can be multiple sown directly into pots or packs
|
|
| Germination: | |
20-25 days at 18-24 °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 80-100 ppm.
|
|
| Growing On: | |
3-4 weeks after sowing transplant 1 plant per plug tray (4x4 cm) and 4 weeks later transplant 3-5 plants into a pot (5-13 cm). Two time transplantation is recommended, when except for multiple sowing in final pot.
|
|
| Media: | |
Use a well-drained, growing perennial substrate with 0-15 % clay, 0-15 % parts (e.g. wood fibres, bark, perlite, sand), 1-1,5 kg/m³ complete balanced fertilizer, 0-2 kg/m³ slow release fertilizer (3-9 months), iron-chelate, micronutrients, pH: 6.0-6.5.
|
|
| Photoperiod / Light: | |
Day length neutral plants. Keep light levels high. Start in spring with supplemental lighting when the temperature rises above 15 °C for good plant quality. With supplemental lighting the cultivation time is decreased down to 3 weeks. Light deficiency is a cause for stretching the shoots.
|
|
| Temperature: | |
Grow at 12-15 °C or outdoors. In winter indoors frost free at 3-5 °C or outdoors. Outdoors fleece cover needed. For the vernalization 8-10 weeks are 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: | |
Low fertilization levels are required. Fertilize the crop weekly with 80-100 ppm nitrogen (at 2 kg/m³ slow release fertilizer in substrate), using alternating a potassium balanced fertilizer (N: K2O-ratio: 1:1,5) and calcium nitrate fertilizer. Avoid high ammonium and high nitrogen levels. Don't fertilize after mid September. In spring fertilize with 100-130 ppm nitrogen of a complete balanced fertilizer.
|
|
| Cultural Hints: | |
Plant in well-drained, calcareous soils and sunny location. Avoid overwatering. The roots are very sensitive to wet substrates. Outdoors good drainage is required.
|
|
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.
