Schedule Crop - Gaura Sparkle White

Gaura Sparkle White

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
Large seed that requires covering for germination. Avoid saturation during germination that can lead to reduced germination. Relatively light feeder in finished. Avoid high ammonia and phosphorous fertilizers like 20-10-20 that can cause excessive soft growth.

Plug Production
Stage 1
Moisture:	Level 4
Temperature:	65-68°F (18-20°C)
Light:	Optional

Stage 2
Moisture:	Level 3-4
Temperature:	66-70°F (19-21°C)
Light:	1,000-2,500 fc (10,800-26,900 Lux)
Fertilizer:	Less than 100 ppm N (Less than 0.7 EC)

Stage 3
Moisture:	Level 2
Temperature:	65-67°F (18-19°C)
Light:	1,000-2,500 fc (10,800-26,900 Lux)

Vernalization:	No
Propagation Key Tips:	For forcing info: See Perennials Forcing Guide. Gaura seed is a nutlet with 2 to 3 seeds, so plug cells may have greater than one seedling.

Growing on to Finish
Growing on Temperature:	(day) 59-70°F (15-21°C) (night) 50-64°F (10-18°C)
