|
| Sowing Method: | |
3-5 seeds per plug
|
|
| Germination: | |
Stage I: 3-5 days at 22-24 °C (72-75 °F)
Stage II: 5-7 days at 22-24 °C (72-75 °F)
Stage III-IV: 18-20 °C (64-68 °F) in media with very low soluble salt levels and pH 5.5-6.0 Requires light for germination. 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 50-75 ppm nitrogen in a well balanced formula. During Stage III and Stage IV fertilization levels can be increased up to 100-150 ppm.
|
|
| Growing On: | |
4-5 weeks after sowing, transplant 1 plants into a pack or pot 8-9 cm (3-3,5'').
|
|
| Media: | |
Use a well-drained, growing substrate with 20-30 % clay, 1-1,5 kg/m³ complete balanced fertilizer, 0-2 kg/m³ slow release fertilizer (3-6 months), iron-chelate, micronutrients, pH 5.5-6.0
|
|
| Temperature: | |
Grow at 16-20 °C (64-68 °F). Temperatures below 16 °C (64 °F) delay flowering and below 10 °C (50 °F) cause chlorosis. Ageratum does not tolerate frost.
|
|
| Fertilization: | |
Moderate fertilization levels are required. Fertilize the crop weekly with 100 -150 ppm nitrogen (at 2 kg/m³ slow release fertilizer in substrate), using a complete balanced fertilizer. Avoid high ammonium and high nitrogen levels. Avoid pH above 6.0, 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.
|
|
| Cultural Hints: | |
Drought stress causes leaf burn. Remove dead flowers.
|
|
* 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.
