Schedule Crop - Lavandula Ellagance

Lavandula Ellagance

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
B9/Cycocel works well. Trimming before transplant can be helpful. Susceptible to botrytis in plug or dense plantings.

Propagation Key Tips:

For forcing info: see Perennials Forcing Guide.
For scheduling info: see Lavender scheduling tool.

Spray damp-off fungicide. Provide good ventilation and active respiration in plug production. Grow on the dry side, with watering in early morning, to allow plugs to dry up during the day. If respiration and fertilisation are too low, Lavandula angustifolia can show "black spots" on cotyledons due to root pressure damage. This is reversible with improved ventilation and higher fertilisation.

Growing on to Finish
Growing on Temperature:	(day) 60-72°F (16-22°C) (night) 54-60°F (12-16°C)
Target Media pH/EC (1:2):	5.8-6.5 pH 1.1-1.4 mmhos/cm
Fertilizer:	100 to 175 ppm N (0.7 to 1.2 EC)
Daylength:	Facultative Long Day
Daylength Notation:	Critical Daylength for Ellagance Purple is 10 hours; Ice and Snow are Obligate Long Day with critical daylength of about 13-14 hours. See Lavender Scheduling Tool at panamseed.com for finishing schedules by region.
Fertilizer Notation:	Apply constant fertilizer at rate 1to 2 (100 to 125 ppm N/0.7 to 1.2 mmhos/cm EC or 150 ppm as needed). Maintain the pH at 5.8 to 6.5 and EC 1.2 to 1.5 mmhos/cm. For overwintering outside, add some extra nitrate-based fertilizer in early Spring (EC 1.5 to 1.6 mmhos/cm) when plants start to re-grow.
Finishing Key Tips:	Avoid planting plugs deep. Keep plug surface same as medium surface. Grow low RH and high light. Let top soil dry in between waterings, but do not allow medium to dry as high EC could cause root damage. Monitor for Botrytis, Root Rot, Leafspot, Aphids and Mites. For shipping, keep soil moist and plant dry. Scheduling is different between colours: Purple is the fastest (as indicated lead time) and Snow adds 4 to 5 weeks. See Scheduling Tool for regional lead times. For overwintering production, cut back just below top foliage; do this mid-Autumn, approximately 4 weeks before dormant period, or in Spring just before regrowth.
