B3820 - AQUILEGIA HYBRIDA, HYBRID COLUMBINE
|
|
'Spring Magic® Mix'
very uniform plants with a nice round habit and good branching. An abundance of very early 5-6 cm flowers that are carried above fine silvery-green leaves makes 'Spring Magic'® a garden favorite. Flowers 2-3 weeks earlier than 'Music'.

|
| Sowing Time: | |
Indoor forcing: Mid May-End July for flowering pots the following year (February onwards); Outdoor forcing: March-April for flowering pots the following year (April onwards)
|
|
| Sowing Method: | |
2-3 seeds per plug
|
|
| Germination: | |
20-35 days at 20-24 °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. Temperatures below 20 °C will increase the germination time.
|
|
| Plug Culture: | |
From Stage II* reduce the soil moisture, but the plug should not dry out and reduce the temperature to 15-20 °C. 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 130-150 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 11-16 cm. Two time transplantation support the young plant quality. For green pots sales, use 8-10 cm pots.
|
|
| Media: | |
Use a well-drained, perennial substrate with 0-15 % clay, 0-15 % organic parts (e.g. wood fibres, bark), 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. Keep light levels high. Flowerings pot production in winter and spring with additional assimilation light will improve the plant quality. Forcing possible from mid January at 12 °C, 16 h long day and assimilation light (30-40 klx) for 4-6 weeks.
|
|
| Temperature: | |
Grow at 14-16 °C. After the roots are developed 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 temperature at 10-12 °C will increase the cultivation time. Avoid high temperature at low light levels. A. hybrida needs for vernalization a chilling period (outdoors or refrigerator) of at least 6-8 weeks at 3-5 °C. The foliage of the plants has to be well developed for the chilling period.
|
|
| 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 potassium balanced fertilizer.
|
|
| Cultural Hints: | |
Aquilegia plant parts are poisonous. Light and cold cultivation similar to a primose culture. Do not cultivate the plants too wet or too dry. Sell A. hybrida with buds. Flowerdrop during transport increase with open 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.
