Aquilegia Music Grower Fact

Aquilegia Music


Life Cycle:Perennial

Familiy, Origin:Ranunculaceae, North America

Sitelocation:Full sun

Garden Height:50 cm,19,69 inch

Crop Time:Plug crop: 7-8 weeks; Green pots: 10-12 weeks; Flowering pots: 9-10 months with vernalization

Seed Form:Raw Seed

Seed Count:1000 K/g

Sowing Method:2-3 seeds per plug

Germination:20-30 days at 20-24 ˇăC 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 20ˇăC 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 ˇăC. 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 10-15 cm or 3 plants into a container. Two time transplantation support the young plant quality.

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 ˇăC, 16 h long day and assimilation light (30-40 klx).

Temperature:Grow at 14-16 ˇăC. After the roots are developed decrease the temperature to 8-10 ˇăC. The temperature change will support the plant quality. In winter indoors frost free at 3-5 ˇăC or outdoors. In spring the plants start to grow for 6-7 weeks at 15-18 ˇăC. Cold temperature at 10-12 ˇăC will increase the cultivation time. Avoid high temperatures at low light levels. A. caerulea needs for vernalization a chilling period (outdoors or refrigerator) of at least 4 weeks at 0-5 ˇăC. 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 complete 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. caerulea with buds. Flowerdrop during transport increase with open flowers
