Sowing Cleome Seeds
BEFORE sowing seeds, chill the cleome seeds at 40ºF (4º)C for five days to encourage earlier germination.
Sow the seeds about 4 weeks before the last frost in your area.
If you cover seed- do so ever so lightly with a thin layer of medium sized vermiculite to maintain moisture levels, However Light is needed for germination.
Media: • pH: 5.5 – 5.8
Light: Light is necessary for germination. If utilizing a chamber, providing a light source of 10 – 100 foot candles, as this will improve germination and reduce stretch.
Temperature: Cleome needs higher than normal temperatures to germinate successfully.<u
Moisture: Wet (4) until radicle (Embryonic Root) emergence. Then begin alternating between moisture levels wet (4) and moist (3) until cotyledon expansion. Allow media to approach level (3) before re-saturating to level (4). Media saturated for over 12 – 14 hours can inhibit germination.
Humidity: 90 – 100%
Bulking – For optimum conditions during the vegetative period, beginning at cotyledon expansion, needed for the root to reach the edge of the plug cell.
- Media: • pH: 5.5 – 5.8.
- Temperature: Continue fluctuating day/night temperatures at 80° – 85°F (26° – 30°C) days and 68° – 70°F (20° – 21°C) nights.
- Moisture: Alternate between moist (3) and medium (2). Allow media to approach level (2) before re-saturating to level (3). Media saturated for more than 12 hours may inhibit growth.
