|
| Sowing Time: | |
January-March for green pots; May- End July for flowering pots
|
|
| Sowing Method: | |
4-5 seeds per plug
|
|
| Germination: | |
20-35 days at 22-25 °C in media with low soluble salt levels and pH: 5.5-6.2. Cover seed with vermiculite, sand or substrate after sowing. Keep soil slightly moist but not wet. When the seeds do not germinate, treat the seeds with cooling for 4-6 weeks at 0-4 °C. Cultivate the following week at 10 °C and later at temperature of 12-15 °C.
|
|
| Plug Culture: | |
From Stage II* reduce the 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 up to 100-150 ppm.
|
|
| Growing On: | |
5-6 weeks after sowing transplant 1 plant per plug tray 3-4 cm and 5-6 weeks later transplant 1 plant into a pot 9-15 cm or 3 plants into a basket.
|
|
| Media: | |
Use a well-drained, perennial substrate with 0-15 % clay, 0-15 % parts (e.g. wood fibres, bark, sand, perlite), 1-1,5 kg /m³, complete balanced fertilizer. 1-2 kg/m³ slow release fertilizer (3-9 months), iron-chelate, micronutrients, pH: 5.5-6.2.
|
|
| Photoperiod / Light: | |
Day length neutral plant. Flowerings pot production in winter and spring with additional assimilation light will improve the plant quality.
|
|
| Temperature: | |
Grow at 14-16 °C. After development of the roots decrease the temperature to
8-10 °C. The temperature change will support the plant quality. In winter indoors frost free at 3-5 °C or outdoors. In spring the plants start to grow for 6-7 weeks at 15-18°C. Cold temperatures at 10-12 °C will increase cultivation time.
|
|
| Fertilization: | |
Moderate fertilization levels are required. Fertilize the crop weekly with 130 -150 ppm nitrogen (at 2 kg/m³ slow release fertilizer in substrate), using a potassium balanced fertilizer (N: K2O-ratio: 1:1,5). Avoid high ammonium and high nitrogen levels. Don't fertilize after mid September. In spring fertilize with
100-150 ppm nitrogen of a complete balanced fertilizer.
|
|
| Cultural Hints: | |
Aquilegia plant parts are poisonous. Light and cold cultivation. Do not cultivate the plants too wet or too dry.
|
|
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.
