Cut flower production in the greenhouse border soil

Depending on bulb size and cultivar, bulbs can be planted in the border soil year-round provided that the soil temperature does not rise above 20°C and that the average greenhouse temperature does not rise above 25°C. The ideal greenhouse temperature is 15°C; a temperature of 18°C can be maintained during the first 3 weeks. This reduces the growing period. Depending on the cultivar and greenhouse temperature, harvesting takes place after 50 to 90 days. Depending on the climate and cultivar, year-round flowering is possible.

Cut flower production in the field

Depending on the climate and bulb size, bulbs can be planted outside in the field year-round provided that the soil temperature does not rise above 20°C and that the average temperature does not rise above 25°C. The ideal temperature is 15 to 17°C. Depending on the cultivar and the climate, harvesting takes place after 50 to 90 days.
