| Sowing Time: | |
Outdoors forcing: Mid June-End August, depending on ambient conditions; Indoor forcing: February-March for green pots, Indoor forcing: mid August-early September for flowering in pots following year
|
|
| Sowing Method: | |
1-2 seeds per plug, can be sown directly into final pot (3-5 seeds)
|
|
| Germination: | |
Stage I: 10-14 days at 20-22 °C; Stage II: 9-10 days at 16-20 °C; Stage III and IV: 7-9 days at 15-20 °C, in media with very low soluble salt levels and pH: 6.0-7.0. Requires light for germination. Before sowing treat substrate with fungicide. Do not cover seeds. Keep soil slightly moist but not wet. Avoid direct sunlight by shading seed after sowing. In field sow not too close (0,75 g/m²).
|
|
| Plug Culture: | |
From Stage II reduce the soil moisture, but the plug should not dry out. Do not let soluble salt level rise above 0,50 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: | |
4-6 weeks after sowing transplant 3-5 plants into a pot (9 cm) or packs.
|
|
| Media: | |
Use a well-drained, growing substrate with 20-30 % clay, 1 kg/m³ complete balanced fertilizer, 0,5-1 kg/m³ slow release fertilizer (3-6 months), iron-chelate, micronutrients, pH: 6.0-7.0.
|
|
| Photoperiod / Light: | |
Day length neutral plants. For growth and flowering Myosotis needs high light levels. Avoid direct sunlight by shading at warm temperatures in autumn or in winter. Light deficiency combined with warm temperatures can be a cause for stretching of shoots.
|
|
| Temperature: | |
Grow at 12-15 °C or outdoors. In winter indoors frost free at 3-5 °C. In January the plants start to grow for 3-5 weeks at 7-13 °C. Grow as cool as possible, but avoid freezing temperatures for a good plant quality. At warm temperatures open airing in time.
|
|
| Fertilization: | |
Moderate fertilization levels are required. Fertilize the crop weekly with 100-150 ppm nitrogen (at 0 kg/m³ slow release fertilizer in substrate), using a potassium balanced fertilizer (N: K2O-ratio: 1:1,5). The plants take up the minerals at 5 °C. Avoid high ammonium and high nitrogen levels.
Don't fertilize after early October. In spring fertilize 150-200 ppm nitrogen of a complete balanced fertilizer. 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. Temperatures below 10 °C inhibit the iron uptake. Therefore take care of, that the temperature is above 10°C for iron fertilization.

|
| Cultural Hints: | |
Avoid that the plant roots grow into the soil underground and cultivate as cool as possible for compact plant development. High relative humidity in winter and wet foliage are a cause for Botrytis. Cultivate slightly moist but not wet.

* 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.
