Schedule Crop - Lavandula Lavance Deep Purple

Lavandula Lavance Deep Purple

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.

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) 60-65°F (16-18°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:	Obligate Long Day
Daylength Notation:	Critical Daylength: 14 hours See Lavender Scheduling Tool at panamseed.com for finishing schedules per region.
Fertilizer Notation:	Apply constant fertilizer at rate 1 to 2 (100 to 125 ppm N/0.7 to 1.2 mmhos/cm EC or 150 ppm as needed).
Finishing Key Tips:	Avoid planting plug too 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. Lavance is best for Summer production, has best bulk. Do not plant early season. Growth is delayed in cool conditions. Use Ellagance Purple for annual early Southeast season and Avignon Early Blue for annual early South and Northwest season. See Lavender Scheduling Tool at panamseed.com for finishing schedules by region. For overwintered production, cut back just below top foliage; do this mid-Autumn, approximately 4 weeks before dormant period, or in Spring just before regrowth.
