Schedule Crop - Heuchera Palace Purple

Heuchera Palace 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.

Notes/Pitfall Management
B9/Cycocel combination works very well for managing growth. Watch for botrytis in plug stage of dense container production. Provide good air flow.

Germination
Seed Form:	PEL
PlugSize:	288
Seeds/Cell:	4
Plug Crop Weeks:	6-8
Days from 50% to maximum germination:	7-10
Cover Seed:	No

Plug Production
Stage 1
Moisture:	Level 4-5
Temperature:	68-72°F (20-22°C)
Light:	Light

Stage 2
Moisture:	Level 4-3
Temperature:	65-68°F (18-20°C)
Light:	2,000-2,500 fc (21,500-26,900 Lux)
Fertilizer:	Less than 100 ppm N (Less than 0.7 EC)

Stage 3

Vernalization:

No - vernalisation not needed when sold for foliage

Propagation Key Tips:

During Stage 1, maintain media moisture at level 4 and RH at 80%. Saturated level 5 media moisture and reduced or fluctuating humidity in Stage 1 can decrease germination and uniformity. Upon removal from germination chamber, place in propagation house with bottom heat at 65-68°F/18-20°C media temperature. Use light mist to maintain humidity, allowing media to dry to moisture level 3.5 and mist at level 3. Maintain under mist for up to 3 weeks as this variety germinates slowly in 2 to 3 flushes. Spray fungicide to prevent damping off. For forcing info: See Perennials Forcing Guide.

Growing on to Finish
Growing on Temperature:	(day) 65-68°F (18-20°C) (night) 60-65°F (16-18°C)
Target Media pH/EC (1:2):	5.8-6.2 pH 1.2-1.4 mmhos/cm
Fertilizer:	175 to 225 ppm N (1.2 to 1.5 EC)
Daylength:	Day Neutral
Fertilizer Notation:	Fertilize every other irrigation with 15-0-15 at 150 to 200 ppm nitrogen. Maintain medium electrical conductivity around 1.0 mmhos/cm (using 1:2 extraction).
Finishing Key Tips:	Do not plant plugs too deep. Keep plug surface at the same level as the media surface. Grow relatively dry. Needs well-drained medium.
