Exposure:
Sun
Garden height:
37″ / 95 cm
Crop time:
6-7 months
Sow time:
December-March for fl wering plants from June-August. July-August for larger flowering plants in the following year
Sowing method:
December-March for fl wering plants from June-August. July-August for larger flowering plants in the following year
Germination:
Germinate at 72-75 °F (22-24 °C) for 7-10 days under lights.
Sow in a well drained media and cover lightly.
Growing On:
Transplant into a well drained media with a pH of
5.5 to 6.5.
Grow on at 60-70 °F (15-21 °C) for perennial pot production.
For cut flower production warmer temperatures result in longer stem length. Temperatures near
75° (24 °C) yield long strong stems. Fertilize at
50-100 ppm nitrate nitrogen after initial transplant increasing to 100-150 ppm once plants are well established.
Media:
Use a well-drained, growing perennial substrate, pH: 6.0-7.5. Field: humus, sandy loamy soils with good drainage.
Temperature:
Grow at 15-18 °C or outdoors. In winter indoors frost free at 3-5 °C or outdoors.
Outdoor fleece cover needed. In spring the plants start to grow at 12-18 °C or outdoors at ambient conditions. Containers can be stored in cold storage and set up in intervals for forcing afterwards.
Fertilization:
High fertilization levels are required.
