Schedule Crop - Leucanthemum Madonna

Leucanthemum Madonna

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
Germinate seed uncovered at moisture 4. Overly wet will cause loss of germination. A-rest at day 12 can help manage plug growth. Avoid planting root bound plugs.

Germination
Seed Form:	RAW
PlugSize:	288
Seeds/Cell:	1
Plug Crop Weeks:	6-7
Days from 50% to maximum germination:	4-10
Cover Seed:	Optional

Plug Production
Stage 1
Moisture:	Level 4
Temperature:	68-77°F (20-25°C)
Light:	Optional

Stage 2
Moisture:	Level 3-4
Temperature:	65-68°F (18-20°C)
Light:	3,000-5,000 fc (32,300-53,800 Lux)
Fertilizer:	Less than 100 ppm N (Less than 0.7 EC)

Stage 3
Moisture:	Level 2-3
Temperature:	65-68°F (18-20°C)
Light:	5,000-7,000 fc (53,800-75,300 Lux)
Fertilizer:	100 to 175 ppm N (0.7 to 1.2 EC)

Stage 4
Moisture:	Level 2-3
Temperature:	60-65°F (16-18°C)
Light:	5,000-7,000 fc (53,800-75,300 Lux)
Fertilizer:	100 to 175 ppm N (0.7 to 1.2 EC)

Vernalization:	No
Juvenility:	Needs a minimum of 10 true leaves before forcing via night interruption (preferred forcing method) or day extension (min. 16 hr.).
Fertilizer Notation:	Use well-balanced Calcium Nitrate-based fertilizer. Do not give continuous feed to prevent high salt levels. Best to leach with fresh water periodically.
Propagation Key Tips:	Avoid high soluble salts. Provide an active climate, including air movement and relatively high light levels. Do not grow too long, as old plugs show irregular growing after transplant.

Growing on to Finish
Growing on Temperature:	(day) 65-72°F (18-22°C) (night) 57-60°F (14-16°C)
Target Media pH/EC (1:2):	5.5-6.2 pH 0.9-1.1 mmhos/cm
Fertilizer:	100 to 175 ppm N (0.7 to 1.2 EC)
Daylength:	Obligate Long Day
Daylength Notation:	Plant needs a minimum of 14.5 hrs. daylength to initiate flowering. Responds very well to night interruption (4 hrs. between 10 pm and 2 am) for Spring Forcing. Juvenility ends at 10 leaves.
Fertilizer Notation:	Use a well-balanced Calcium Nitrate-based fertilizer. Fertilizer rate at 140 to 160 ppm. Do not use continuous feed to avoid high soluble salt levels. Best to leach with fresh water periodically.
Chemical Sensitivity:	Do not use Abamectin (trade name Avid/Vertimec) or allow it to be in contact (even gas from a neighboring compartment). This will kill the crop.
Bulking Strategy:	Use advised temperatures, grow below 12-hour daylength and watch out for light pollution from neighboring departments.
Finishing Key Tips:	For 2 Gallon, use 3-4 plugs per pot.
