Cultivation tips for cyclamen during the summer – autumn transition phase

1. Length of flower stems
2. Botrytis plan
3. Crop protection

Length of flower stems

Make sure that the flower stems of the summer cyclamen such as the Super Serie Verano, Donatello and Compact, remain long enough in autumn. Refrain from using growth regulator as soon as the buds begin to form, keep the day and night temperature the same and do not apply a temperature drop.

Botrytis plan

The transition from warm and dry weather to more humid conditions allows Botrytis to develop more easily. This can be prevented as much as possible using the following methods:

• Make sure you use a Botrytis preventative treatment. Carefully select the product and time it well (drying conditions), ensuring that the plants have enough time after spraying to dry before nightfall. Spray early in the morning, if possible.
• Water in the early morning, preferably on a drying day, and only from underneath or using drippers.
• In an ebb and flow watering system, reduce the water level (height) and make sure the pots stand in water for the shortest time possible.
• Set a minimum pipe temperature (humidity) preferably right above the plants. Do not heat soil or heat as little as possible.
• Space the plants further on time; give them plenty of space so they do not touch each other.
• Set a minimum ventilation and create good air circulation, ensuring an active climate. Use vents to create ample air movement in the greenhouse.
• Prevent guttation of the plants by maintaining a sufficiently high EC in the pot (0.8-1.0 mS/cm). As you decrease the frequency of watering, increase the EC gift and check the EC in the pot.

Crop protection

The presence of insects is quite high at the moment due to the warm period. We are encountering many Duponchelia and thrips infestations.
For Duponchelia: hang up pheromone traps to thoroughly check for adult insects. Scout your plants regularly.
For thrips: hang up plenty of catch plants and intensively check the plants for leaf thrips (Echino or Setosus). Make sure to thoroughly check under the leaves. A thrips infestation is recognisable by slightly bulging leaves and a reddish-brown discolouration on the underside of the leaves.
Also be sure to scout for aphids and caterpillars in your plants in the coming period.
Consult your plant protection expert for the appropriate treatments.
