Schedule Crop - Lavandula Bandera

Lavandula Bandera

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
Crops can be delayed by early Spring cloudiness. Depending upon region it may be beneficial to add 2 weeks to the scheduling. Supplemental lighting beneficial. As with all lavender, provide good air flow and keep the foliage dry as possible. Avoid high humidity. B9/Cycocel can tone nicely.

Propagation Key Tips:

At sowing, do not cover the seeds too heavily, as it will significantly decrease germination.
At Stage 1 germination, pull from the germination chamber at 10 to 15% visible radicle emergence and grow at 60 to 65°F (16 to 18°C) to avoid stretch. L. stoechas may stretch easily at higher temperatures in the early plug phase.
Keep active growing environment. Spray damp-off fungicide. Genetically compact plants should not need PGRs in plug production. If needed, use B-Nine (daminozide) spray 2,500 ppm. High pH (> 6.8) causes chlorosis.

Growing on to Finish
Growing on Temperature:	(day) 65-68°F (18-20°C) (night) 55-64°F (13-18°C)
Target Media pH/EC (1:2):	5.5-6.0 pH 1.0-1.2 mmhos/cm
Fertilizer:	100 to 175 ppm N (0.7 to 1.2 EC)
Daylength:	Facultative Long Day
Daylength Notation:	See Lavender Scheduling Tool at panamseed.com for finishing schedules by region. Long day beneficial, but will flower in short days.
Fertilizer Notation:	Bandera generally needs light to moderate fertilization. Apply fertilizer at rate 2 (145 to 175 ppm N; 1.0 to 1.2 mmhos/cm). Increase potassium-to-nitrate ratio in later growing-on stage.
Chemical Sensitivity:	Genetically compact and branching; grow in an active climate and use caution with high concentrations of PGR in plug or finished stage.
Finishing Key Tips:	Don't plant too deep since Bandera has low and deep branching, and Botrytis could more easily affect plants. Need cool production to reach sufficient flag size, see Scheduling tool. High pH (above 6.8) can cause leaf chlorosis.
