AmeriSeed
Growing Instruction : Sowing Seed
1. Sowing seeds on saturated media
2. Light is affect for germination, do not cover the seeds
Break Rosetting Method
1. After sowing, keep tray in dark and moisture
condition
2. Store in cooling chamber at 10-12 oC for 35
days or 5-6 oC for 14 days to break Rosetting
(Precooling treatment )
AmeriSeed
Growing Instruction : Plug Stage
1. Germination stage 8-10 days
2. Control temperature between 20 -23 oC until first true leaves reach the holes
edge. (1-1.5 month)
3. Move seedling to outside and provide a light fertilizer 100 ppmN from a wellbalanced calcium nitrate based fertilizer.
4. Seedling should have 4-6 true leaves then ready to transplant into the cut
flower bed.

Growing Instruction : Planting
1.

4.
5.
6.
7.
Prepare bedding with rich Organic soil, Pest and Pathogen free.
Lisianthus grow best with between pH 6.0-6.8. Use Dolomite to adjust pH which
give Calcium and Magnesium.
Cover bedding with silver plastic. This will help to keep lower temperature in soil.
Transplant seedling when young before it becomes root-bond. First seedling will
flower earlier with shorter stems especially under long day conditions. For
summer, plant when seedlings have 4 true leaves and 6 true leaves for winter.
Do not plant too deep to avoid stem rot.
Avoid to damage roots during transplanting. Poor growth, Delayed maturity and
Fail growing are caused by damage roots.
Lisianthus requires sufficient water in first growing stage. Before planting, soil
must be sufficiently wet.
AmeriSeed
Growing Instruction : Bed Preparation
1.
Cultivate bedding depth 45 cm.
2.
Add dolomite 750 kg/acre, 15-15-15 125 kg/acre, compost 750 kg/acre and Rice
Husk.
3.
Plant spacing10x10cm. Do not plant on the central for more ventilation and
sunlight.
AmeriSeed
Growing Instruction : Spacing
Suggestion :
4 rows per bed will be more better benefits
management to horticulture operation.
AmeriSeed
Growing Instruction : Irrigation



At 2nd weeks after transplant, use top irrigation with sufficient
water for a good plant establishment and do not let the soil dry
to avoid Rosetting
Reduce watering to avoid of Botrytis problem.
Drip irrigation is the best way for irrigate
Insufficient irrigation after transplanting will cause
root problem and lead to Rosette problem
AmeriSeed
Growing Instruction : Fertilization
 Lisianthus is not cultivated by fertilizer but by water.
 Lisianthus does not require high fertilizer levels. Maintain soil EC level
around 1.0 -1.3 mmhos. Apply with liquid fertilizer 150 ppmN for 6 days
and irrigation to reduce EC once a week.
 To prevent tip burning, foliar sprays of calcium by weekly starting at 20
cms. height
Tip burning will caused by high sunlight, if plants insufficient
calcium or too much nitrates.
AmeriSeed
Growing Instruction : Light intensity
 Light intensity and day length can effected growth, crop time and flower
quality
 High light intensity will provide quality plant with more bud and good flower
 Shading can effected Blind buds and insufficient of petals color
Blind problem caused by shading
AmeriSeed
Growing Instruction : Day Length
Day length:
 Lisianthus is Long day plant.
 Long day length condition: plant will be short growing period and flower bud will be
accelerated. Plant will be early to flowering with shorter stem.
 Short day length condition: Plant will delay flowering, late to flowering and long
stem
Lisianthus Group:




Group 1* : Early flowering type
Group 2* : Middle flowering type
Group 3** : Middle late flowering type
Group 4** : Late flowering type
*Group 1 & 2: Suitable verities for short day length, low light intensity and cool
condition ( Early Spring flowering)
**Group 3 & 4: Suitable verities for long day length, high light intensity and warm
condition ( Autumn flowering)

Transplant : After 3 Month

Harvesting : Pre-harvest
 It is necessary to reduce irrigation and fertilizer before harvesting.
Upper : Not reduced irrigation before harvesting : Inter-node and flower stems are stretching.
Lower : Reduced irrigation before harvesting : Showing hard stems with shot flower stem
AmeriSeed
Harvesting : Harvest
 Harvest when one flower are opened. Remove the first bud before harvesting.
This will help to increases the number of flowers
Left : One flower opened for oversea market
Right : 3-4 flowers open for domestic or local market
 The best time to harvest is in the morning because of plants contain high
concentration of sugar at that time
AmeriSeed
Harvesting : Post-harvest
 After cutting, put cut flower stems in
warm water, temperature around 20oC
and store in a refrigerator at 4 0C.
 Preservative added after cutting is
recommended. It will help to increases
40-50% vase life
AmeriSeed
Problem : Rosetting
 Rosetting is a natural survival response
 Main causes of Rosetting problems
•
•
•
High temperatures during germination and cotyledon stages
Root damage caused by drying out from lack of irrigation and
Burning from apply high concentration fertilizer
 To avoid Rosetting from sowing to transplant is to control the
temperature by cooling equipment
 Sufficient irrigation into flower bed before planting will help to reduce soil
temperature and establishment root system
 Soil preparation is good for taproot system.
