|
|
| Seed Count: | |
0 K/g
|
|
| Sowing Method: | |
1-2 seeds per plug
|
|
| Germination: | |
Stage I: 10-18 days at 18-21 °C, Stage II-IV: 16-18 °C. In media with low soluble salt levels and pH 5.8-6.5. Requires light for
germination. Cover seed lightly with vermiculite after sowing. Keep soil slightly moist but not wet. Avoid direct sunlight by shading seeds after sowing.
|
|
| Plug Culture: | |
From Stage II reduce the soil moisture, but the plug should not dry out. Reduce the temperature to 16-18 °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 150-200 ppm.
|
|
| Growing On: | |
5-6 weeks after sowing transplant 1 plant into a pot (13-15 cm) or 2-3 plants into a
container (3-5 l). Plant cut flowers in 35-40 x 25-40 cm space and use nets to keep the stems upright.
|
|
| Media: | |
Use a well-drained, growing substrate, 1,5-3 kg/m³ complete balanced fertilizer, 0-2 kg/m³ slow release fertilizer (3-9 months), iron-chelate, micronutrients, pH 5.8-6.5. Field: loamy sandy to sandy humus soils with good drainage and good nutrition levels. Standard fertilization: 80-100 g/m2 of a slow release fertilizer.
|
|
| Photoperiod / Light: | |
Day length neutral plant. High light levels improve the flower initiation and the plant quality. For a compact plant habit keep short day conditions with high light intensity during the vegetative growth and afterwards turn to long day conditions with high light intensity for flowering.
|
|
| Temperature: | |
Grow at 12-15 °C or outdoors. Overwinter indoors frost free at 3-5 °C.
|
|
| Fertilization: | |
Moderate fertilization levels are required. Fertilize the crop weekly with 130-150 ppm nitrogen (at 2 kg/m³ slow release fertilizer in substrate), using a complete balanced fertilizer. Don't fertilize after mid September. In spring fertilize 150-200 ppm nitrogen of
a potassium balanced fertilizer (N: K2O-ratio: 1:1,5). 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 1-2 times.
|
|
| Cut Flowers: | |
Cut flower stems can be harvested, when buds show colour. Put the stems in warm
water immediately. Vase life: 8-10 days. Cold storage is not recommended. Avoid the formation of seedpods in order to encourage the following flowering. Yield: 15-25 stems/plant in first year; up to
40 stems/plant during 2 consecutive years.
|
|
| Cultural Hints: | |
Dry, light and airy cultivation. The roots are very sensitive to wet substrates/soils. For
cultivation allow for the pots to dry thoroughly between irrigations. High temperature difference between day and night can be a cause for delayed and decreased flowering.

* Germination Stages (from seed to finished young plant)
| Stage I: | Starts with the radicle breaking through the testa. The roots are touching the medium. Ends with fully developed cotyledons. |
| Stage II: | Starts from fully developed cotyledons. Ends with the fully developed true leaf or true leaf pair. |
| Stage III: | Starts from the fully developed true leaf or true leaf pair and ends with 80% of the young plants being marketable. |
| Stage IV: | All young plants are ready for sale and in the process of being hardened off. This stage lasts about 7 days. |
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.
