Trachelium Lake
(Trachelium caeruleum)

Germination

•  Time of radicle emergence (5-7 days)
•  Soil temperature 62-70°F (16-21°C).
•  Keep media evenly moist but not saturated.
•  Do not cover or bury the seed.
•  Light at 100-500 foot-candles may be beneficial for germination.
•  Soil pH 6.0 and soluble salts (EC) less than 1.0 mmhos/cm (2:1 extraction).
•  Trachelium is very sensitive to high salts, particularly high ammonium, during germination.
•  Keep ammonium levels less than 10 ppm.

Plug Production

STAGE 1 Time of radicle emergence (5-7 days)

•  Soil temperature 62-70°F (16-21°C).
•  Keep media evenly moist but not saturated.
•  Do not cover or bury the seed.
•  Light at 100-500 foot-candles may be beneficial for germination.
•  Soil pH 6.0 and soluble salts (EC) less than 1.0 mmhos/cm (2:1 extraction).
•  Trachelium is very sensitive to high salts, particularly high ammonium, during germination.
•  Keep ammonium levels less than 10 ppm.

STAGE 2 Stem and cotyledon emergence (7-10 days)

•  Soil temperature 62-70°F (16-21°C).
•  Reduce moisture levels once radicle emergence occurs! Allow the soil to dry out slightly before watering for best germination and rooting.
•  Keep soil pH 6.0 and EC less than 1.0 mmhos/cm.
•  Keep ammonium levels less than 10 ppm.
•  Begin fertilizing with 50 75 ppm N from 15 0 15 or a calcium/potassium nitrate feed once cotyledons are fully expanded.
•  Alternate feed with clear water.
•  Irrigate early in the day so foliage is dry by nightfall to prevent diseases.

STAGE 3 Growth and development of true leaves
(7 days)

•  Night temperature 62°F (16°C)
•  Day temperature 70°F (21°C)
•  Allow the soil to dry between irrigations but avoid permanent wilting to promote root growth and control shoot growth.
•  Maintain soil pH 6.0 and EC less than 1.0 mmhos/cm.
•  Increase feed to 75-100 ppm N from 20 10 20 alternating with 15 0 15 or other calcium/ potassium nitrate fertilizer.
•  Fertilize once a week.
•  Use DIF whenever possible, especially the first 2 hours after sunrise, to control plant height.

STAGE 4 Plants ready for transplanting or shipping (7 days)

•  Soil temperature 62°F (16°C).
•  Allow soil to dry between irrigations.
•  Maintain soil pH 6.0 and EC less than 1.0 mmhos/cm.
•  Fertilize with 15 0 15 or calcium/potassium nitrate feed at 100 150 ppm N as needed.

Growing On to Finish

TRANSPLANTING

•  Transplant when the second true leaves unfold.
•  When buying in seedlings or plugs, allow seedlings 24 hours to acclimate to the greenhouse conditions, then transplant promptly.
•  Delayed flowering and loss of final product quality occurs when seedlings are kept too long in plug trays.
•  If holding is unavoidable, store plugs at 36-39°F (2-4°C) under fluorescent lights at 250 foot- candles 14 hours per day.
•  Treat with a fungicide prior to storage to prevent botrytis.

SPACING

•  When grown in pots, space pot to pot.
•  If grown in the field, rows are 6-9 inches apart.

SUPPORT

Support material is not necessary.

TEMPERATURE

•  Autumn and winter cultivation – 52-55°F (11-13°C) first 3 weeks then average 55°F night and 60°F days.
•  February-April (high light intensity) – 60°F (15°C) nights, 65°F (18°C) days.
•  Late spring-summer – 60-68°F (15-20°C) nights, max. 78°F (25°C) days.

WATER

Keep soil moist. Water frequently to leach soil.

LIGHT

•  Maintain light levels below 3500 ftc. while maintaining moderate temperatures.
•  Flowering is hastened in winter by increasing day length to initiate buds.

MEDIA

•  The growing medium should allow adequate aeration to the roots yet hold a steady supply of moisture.
•  The greater the aeration of the medium, the more forgiving the medium is to overwatering.
•  Growing media in benches must be better aerated than media used to grow stocks directly in the ground, because the bench bottom creates a “perched water table” which limits water drainage.
•  Ground beds in locations with sandy loam soils may be suitable for growing stocks without any amendments.
•  Heavy soils should be improved prior to planting by tilling in organic material such as peat moss, rice hulls, compost, or decomposed manure.
•  Growing medium for raised benches should consist of less than 50 percent field soil, with the remaining percentage consisting of a mixture of more than one of the following: vermiculite, perlite, peat moss, composted bark, or rice hulls.
•  Medium must be free of disease-causing organisms.
•  If using soil, it will be necessary to disinfect the media.
•  Perform a soil test of the growing medium before planting.
•  EC should be between 2.0-2.25 mmhos.
•  Ammonium-based nitrogen less than 10 ppm.
•  pH 6.0.

FERTILIZATION

•  Feed at 200 ppm of 20-10-20 once every other irrigation until buds form.
•  Switch to potassium chloride for the last four weeks of crop when buds have formed. EC can be 2.0-2.25 mmhos/cm.
•  Water with clear water to rinse foliage and to leach soil frequently.

Post Production Care

HARVESTING

•  The best quality flowers for the consumer are those cut with 75% of the flowers open.
•  Premature harvesting leads to poor color development and reduced flower size as flowers continue to open.

WATER

•  For maximum vase life, place trachelium stems in water as soon as possible after cutting.
•  Remove foliage on the lower third of the stems, then grade and bunch.
•  To condition for immediate use or shipping, place the flowers in warm water (70-75°F, 21-24°C) containing floral preservatives.
•  Select a floral preservative which contains sucrose as well as 8-HQC (8-hydroxyquinoline citrate) or other bactericide to facilitate water uptake and inhibit stem plugging.

TEMPERATURE

Hold at 45-50°F (7-10°C) at least 6 to 8 hours or overnight.

LIGHT

Color development in enhanced by holding the stems in approximately 200 foot-candles light.

STORAGE AND SHIPPING

•  Trachelium can be shipped dry if precooled at 33° F (1°C).
•  If stored dry, rehydrate and condition in cool water.
•  Trachelium can be shipped horizontally, but best quality is kept when trachelium is shipped in buckets of water.
•  Trachelium are not sensitive to ethylene.

COMMON PROBLEMS

Insects: Aphids, Leaf rollers, Thrips

Diseases: Bacterial Blight, Pythium, Phytopthora, Rhizoctonia
