February-May
|
|
| Sowing Method: | |
1-2 seeds per plug
|
|
| Germination: | |
7-10 days at 20 °C, in media with low soluble salt levels and pH: 5.5-6.2. Cover seed lightly with vermiculite after sowing. Keep soil steadily 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 15-17 °C. Do not let soluble salt level rise above 0,5 EC. Start fertilization at 50 ppm nitrogen in a well balanced formula. During Stage III and Stage IV fertilization levels can be increased to 150 ppm.
|
|
| Growing On: | |
3-4 weeks after the sowing transplant 1 plant into a pot (9-11 cm) or pack and 3 plants into container (3-5 l).
|
|
| Media: | |
Use a well-drained, growing substrate with 20-30 % clay, 1,5 kg/m³ of a complete balanced fertilizer, iron-chelate, micronutrients, pH: 5.8-6.5.
|
|
| Temperature: | |
Grow at 16-18 °C. The lower the cultivation temperature, the longer the cultivation time. In order to harden the plants for selling the temperature can be decreased to 12-14 °C. Melampodium does not tolerate temperatures below 10 °C.
|
|
| Fertilization: | |
Moderate fertilization levels are required. Fertilize the crop weekly with 100-150 ppm nitrogen, using a complete balanced fertilizer. Avoid high ammonium levels and high nitrogen levels. Prevent magnesium deficiency by applying magnesium sulphate (0,025 %) 1-2 times and in case of iron deficiency (above pH 6.0) apply iron-chelate for 1-2 times.
|
|
| Cultural Hints: | |
Melampodium as a marsh plant has a high water demand. Melampodium does not tolerate dry substrate and drought stress can cause necrosis on leaf edges. Protect the plants against cold night temperatures outdoors.
|
|
* 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.
