|
|
| Sowing Method: | |
2-3 seeds per plug
|
|
| Germination: | |
14-16 days at 15 °C, in media with low soluble salt levels and pH: 5.5-6.0. Requires light for germination. Do not cover seed. Keep soil slightly moist but not wet.
Avoid direct sunlight by shading seed after sowing. Temperatures above 16 °C may inhibit the germination.
|
|
| 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 100-150 ppm.
|
|
| Growing On: | |
6 weeks after sowing transplant 1-2 plants into a pot (9-12 cm).
|
|
| Media: | |
Use a well-drained, growing substrate with 20-30 % clay, 1,5 kg/m³ complete balanced fertilizer, iron-chelate, micronutrients, pH: 5.5-6.0.
|
|
| Temperature: | |
Grow at 10-15 °C. Calceolaria integrifolia does not tolerate frost.
|
|
| Fertilization: | |
Moderate fertilization levels are required. Fertilize the crop weekly with 100-150 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. After iron-chelate fertilization rinse the leafs with water. Avoid salt levels in substrate above 2 g/l. Control the pH in substrate regulary.

|
| Cultural Hints: | |
Cultivate plants slightly moist but not wet. Remove the plant tops after transplanting for better branching and good plant quality.
|
|
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.
