Cyclamen (Cyclamen persicum & Cyclamen coum)
Part II Successful finishing
Syngenta Flowers APAC Technical Webinar for Tropical Regions 17-09-2025 2 p.m.
Inka Orange 70041091
Short recap of previous Webinar.
• Introduction into Syngenta cyclamen assortment. • 5 elements of successful cyclamen young plants production. • Substrate quality • Germination stage. Keep seeds on the top. • Provide total darkness during germination. • Maintain sufficiently high air humidity until the first true leaves appear. • Keep relatively cold temperature for the seedlings. • Protect your cyclamen from Fusarium . • Pest’s management (fungus gnats and thrips).
Your questions are welcome through Q&A!

Substrate.
Impatiens’s roots rather sensitive.
• …avoid composts and plant residuals.
• Suitable substrate components: peat > cocopeat > wood fiber peat > rice husk or composts . With particle size 0―5 mm. • Use a mixture: 50/50 peat + cocopeat or 50/50 cocopeat + > wood fiber .
•
Add 30 % leavening agent: perlite > sand > zeolite > vermiculite
Wood fiber peat
Rice husk
Is the best solution
Cocopeat

Fertigation tips before blooming.
Feed your Cyclamen seedlings properly.
• Provide 125―175 ppm of nitrogen (N). • You can provide proper amount of N by 0.85―1.2 g/l of 18 -5- 18 , 15 -3- 15 or similar.
• Optimal EC in the water 1.5―2.0.
• Optimal EC in the substrate (SME*): 0.9―1.3 mS/cm. • Don’t change EC more than 0.3 mS/cm. • Don’t apply to much phosphorus. • Provide enough calcium .
Feed your cyclamen well.
• Substrate and water pH: 5.8―6.2

Fertigation tips for blooming stage.
Feed your Cyclamen seedlings properly.
• Optimal EC in the water 1.5―2.0 (2.3 is possible in sunny and hot condition). • The same 125―175 ppm of nitrogen (N). • You can provide proper amount of N by 0.85―1.2 g/l but with different NPK 18 -5- 35 , 17 -10- 40 or similar.
Feed your cyclamen well.
• Don’t forget about calcium!!! .

Ca deficiency.
How to provide your Cyclamen with calcium?
• The same concentration. • 0.85―1.2 g/l but with calcium nitrate (Ca(NO 3 ) 2 ).
What is your choice?
• Optimal EC in the water solution 1.5―2.0 in sunny and hot condition).
• Every 3―5 watering.
Plant with the Ca deficiency.
Normal plants.

Make the good shape.
Spacing Cyclamen helps to avoid the stretchong.
• Shading causes petioles to stretch.
Spacing provides the good shape.

Fusarium management.
Diseases management is not only the chemicals application!
Elements of protection…
• Hygiene & quarantine.
• Proper watering(!!!)*. • Don’t use recycling water for the seedlings.
• Scouting. • Growing conditions (T, RH, Water, Light, Fertigation)*. • Clean area.
Plants infected Fusarium oxysporum
• Fungus gnat management.
• Chemical protection.
Fusarium.
* Overwatering or drying out are common cause of fusarium infection. The corm shrinkage makes the small wounds that used by fungal conidia as a gate.
