| Crop Time: | |
Plug crop: 3-4 weeks; Flowering pots: 9-10 weeks
|
|
| Seed Form: | |
Coated Seed
|
|
| Seed Count: | |
0 K/g
|
|
| Sowing Method: | |
1 seed per plug, sowing directly into final pots is recommended.
|
|
| Germination: | |
Stage I: 7-10 days at 25 °C. Stage II-IV: 11-20 days at 18-20 °C. In media with low soluble salt levels and pH 5.5-6.0.
Requires light for germination. Cover seed lightly with vermiculite after sowing.
Keep soil slightly moist but not wet.
|
|
| Plug Culture: | |
From Stage II reduce the moisture, but the plug should not dry out. Do not let soluble salt level rise above 0,75 EC. 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: | |
3-4 weeks after germination transplant 1 plant into a pack or pot (9-10 cm).
|
|
| Media: | |
Use a well-drained, growing substrate with 15-30 % clay, 1,5-2 kg/m³ complete
balanced fertilizer, iron-chelate, micronutrients, pH 5.5-6.0.
|
|
| Temperature: | |
Grow at 18-20 °C. At the end of the cultivation time decrease the temperature
to 16 °C. Avoid temperatures below 16 °C, because Celosia needs warm temperatures to grow.
|
|
| Fertilization: | |
Moderate fertilization levels are required. Fertilize the crop weekly with 150-200 ppm nitrogen, using a complete balanced fertilizer. Avoid high ammonium and high
nitrogen levels. Prevent magnesium deficiency by applying magnesium sulphate (0,025 %) 1-2 times and in case of iron deficiency apply iron-chelate for 1-2 times.
|
|
| Cultural Hints: | |
Cultivate plants firstly slightly moist and later dry. Avoid inhibited and stressful
cultivation (in particular low temperatures or nutrition deficiency), because the flower initiation may start before plants have reached sufficient size and thus the plant quality decreases.

* 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.
