|
|
| Seed Count: | |
833 K/g
|
|
| Sowing Method: | |
1-3 seeds per plug
|
|
| Germination: | |
7-14 days at 18-22 °C in media with low soluble salt levels and pH: 5.8-6.5.
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 18-20 °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). At March transplant into a field from poly tunnel or greenhouse (frost free). At May transplant into a field outdoors. Plant cut flowers in 25-30 x 30 cm space.
|
|
| Media: | |
Use a well-drained, growing substrate with 15-30 % clay, 0-15 % perlite, 1-3 kg/m³ complete balanced fertilizer, iron-chelate, micronutrients, pH: 5.8-6.5. Field: loamy sandy soils with good drainage. Standard fertilization: 40-60 g/m² slow release fertilizer.
|
|
| Photoperiod / Light: | |
Long day plant. For the flower initiation vegetative growth long day (13-14 h) are required. Keep light levels high.
|
|
| Temperature: | |
Grow at 15-18 °C or outdoors. Temperatures below 13 °C will result in leaf chlorosis and will inhibit the growth. Craspedia does not tolerate frost.
|
|
| Fertilization: | |
Low-moderate fertilization levels are required. 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 50 % of the globular flowers are open. Vase life: very good. The stems can be harvested for dried flowers, when the pigmentation of the globular flowers are just visible.
|
|
| Cultural Hints: | |
Production at high light levels and relative high temperatures. Craspedia is very sensitive to overwatering. Forcing in poly tunnel or in greenhouse is possible.
|
|
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.
