|
|
| Sowing Method: | |
1-2 seeds/pellets per plug
|
|
| Germination: | |
Stage I: 7-14 days at 21-23 °C and relative humidity of 95 %. Maintain high moisture. Light
germinator, don't cover seeds or pellets. Additional light (50 W/m2) accelerates germination
and improves quality of the seedlings;
Stage II: 7-14 days at 20-21 °C. Continue long day lighting (14 h) and avoid saturated
or dry media, lower humidity levels. Water temperature should be 18 °C;
Stage III-IV: 28-42 days at 18-20 °C.
|
|
| Plug Culture: | |
From Stage II reduce the moisture, but the plug should not dry and cultivate under long day (14 h). Do not let soluble salt level rise above 0,5 EC. The roots are sensitive to high salt levels in substrates. Start fertilization at 50 ppm nitrogen in a well balanced formula. During Stage III and Stage IV fertilization levels can be increased up to 150-200 ppm.
|
|
| Growing On: | |
6 weeks after sowing transplant 1 plant per plug tray (4x4 - 6x6 cm) and 12 weeks after
sowing transplant 1 plant into a pot (10-12 cm) or 3-4 plants into a hanging basket
(20-30 cm). Avoid cool substrate at transplantation. Two time transplantation supports root
development and young plant quality.
|
|
| Media: | |
Use a well-drained, growing substrate with 15-30 % clay, 0-20 % perlite, 1-2 kg/m2
complete balanced fertilizer, iron-chelate, micronutrients, pH 5.5-6.2.
|
|
| Photoperiod / Light: | |
Long day plant. Long day (14-16 h) is necessary for flower initiation. In winter
assimilation light is recommended for good plant development and quality and will shorten
crop time. Short days will result in tuber formation.
|
|
| Temperature: | |
Grow at 16-18 °C. 10 days before selling temperature can be decreased
to 16 °C. Temperatures below 14 °C will result in tuber formation and crop delay.
|
|
| Fertilization: | |
Moderate fertilization levels are required. Fertilize weekly with 150-200 ppm
nitrogen, using a complete and potassium balanced fertilizer (N:K2O-ratio: 1:1,5). Keep low
ammonium levels, otherwise the roots become damaged. At high nitrogen levels the foliage can
become very big. Avoid pH above 6.5, as high pH causes iron deficiency. Apply chelated iron,
if chlorosis becomes a problem. To prevent magnesium deficiency apply magnesium sulphate
(0,025 %) 1-2 times. Additional foliage fertilization with potassium supports compact plant
growth and provides a dark green foliage colour. Avoid high soluble salts in the soil.
|
|
| Cultural Hints: | |
Before selling harden the plants at 16 °C and UV light. Keep sufficient distance
between plants in greenhouse. Do not cultivate too wet, because roots are sensitive. Avoid high
relative humidity in greenhouse. Check plants for Powdery Mildew and treat appropriately.

* 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.
