Schedule Crop - Aquilegia Swan

Aquilegia Swan

Data is gathered from our Elburn, Ill., trials (Zone 5a) for a North American audience. Warm-climate growers: expect 1-2 weeks earlier finishing. Cool-climate growers: expect 1 week slower. Dates based on standard 288 plug size.

Notes/Pitfall Management
Plugs must be grown to a minimum 12 leaf stage and then chilled-4 weeks below 41F or 6 weeks below 52F. Force from dormancy warm (65F day/night) for two weeks before cooling for greatest uniformity.

Cover Seed:	Yes

Plug Production
Stage 1
Moisture:	Level 4
Temperature:	70-75°F (21-24°C)
Light:	Light
Fertilizer:	Less than 100 ppm N (Less than 0.7 EC)

Stage 2
Moisture:	Level 3-4
Temperature:	65-70°F (18-21°C)
Light:	2,500 fc (26,900 Lux)
Fertilizer:	Less than 100 ppm N (Less than 0.7 EC)

Stage 3
Moisture:	Level 2-3
Temperature:	65-70°F (18-21°C)
Light:	2,500 fc (26,900 Lux)
Fertilizer:	100 to 175 ppm N (0.7 to 1.2 EC)

Light:	5,000 fc (53,800 Lux)
Fertilizer:	100 to 175 ppm N (0.7 to 1.2 EC)

Vernalization:	Yes - but vernalization temperature can go as high as 55°F (13°C) nights and 60°F (15°C) days; duration of 4 weeks at 41°F (5°C) or 6 weeks at 55°F (13°C); start cool treatment after 12 to 15-leaf stage
Juvenility:	Start cool treatment after 12 to 15-leaf stage

Growing on to Finish
Growing on Temperature:	(day) 60-68°F (16-20°C) (night) 55-64°F (13-18°C)
Target Media pH/EC (1:2):	5.8-6.2 pH 1.0-1.5 mmhos/cm
Fertilizer:	175 to 225 ppm N (1.2 to 1.5 EC)
Daylength:	Day Neutral
Daylength Notation:	Aquilegia is a day-neutral plant after vernalization. Long days of 14 hours or longer could stimulate stem elongation and slightly hasten flowering after the vernalization period.
Bulking Strategy:	Vernalization temperature can go as high as 55°F (13°C) at night and 60°F (15°C) at day; duration of 4 weeks at 41°F (5°C) or 6 weeks at 55°F (13°C); start cool treatment after 12 to 15-leaf stage.
Finishing Key Tips:	Requires night temperatures below 55°F (13°C) to initiate flower buds.
