TECHNICAL INFORMATION

Life Cycle:Perennial

Familiy, Origin:Brassicacae, South Europe

Sitelocation:Full sun - partial shade

Garden Height:25 cm,9,84 inch

Natural flowertime:May - June

Crop Time:Plug crop: 4-6 weeks; Green pots: 10-12 weeks; Flowering pots: 14-16 weeks, annual production is possible; Flowering pots: 6-7 months, including wintering

Sell Period:March-April

Seed Form:Raw Seed

Seed Count:600 K/g

Sowing Method:1 seed per plug

Germination:6-12 days at 20-21 °C, in media with very low soluble salt levels and pH: 5.5-6.5. Cover seed lightly with vermiculite after sowing. Keep soil slightly moist but not wet.

Plug Culture:From Stage II* reduce the soil moisture, but the plug should not dry out and reduce the temperature to 15-18 °C. Do not let soluble salt level rise above 0,5 E.C. Start fertilization at 50 ppm nitrogen in a well balanced formula. During Stage III and Stage IV fertilization levels can be increased to 100-150 ppm.

Growing On:3-4 weeks after sowing transplant 1 plant into a pot (9-12 cm).

Media:Use a well-drained, growing substrate with 10-30 % clay, 0-15 % parts (e.g. bark, sand, perlite), 1,5-3 kg/m3 complete balanced fertilizer, 0-2 kg/m3 slow release fertilizer (3-9 months), iron-chelate, micronutrients, pH: 5.5-6.5.

Photoperiod / Light:Day length neutral plants. In winter and early spring additional assimilation light is recommended in combination with warm cultivation temperatures at 15-18 °C. A cultivation in cold greenhouse or field at ambient conditions is possible. In this case the flowering is in March-May.

Temperature:Grow at 10-15 °C or outdoors. In winter indoors frost free at 3-5 °C or outdoors. Outdoor fleece cover needed. In early spring (from CW 51 on) the plants start to grow at 12-15 °C. Cold temperatures at 8-10 °C will increase the cultivation time (10-14 weeks in total). Temperatures below 8 °C increase the cultivation time at 4-6 weeks. A chilling period (vernalization) for flower initiation is not required, but cultivate as cold as possible. This will promote a good branching and a uniform flowering.

Fertilization:Moderate-high fertilization levels are required. Fertilize the crop weekly with 100-150 ppm nitrogen (at 2 kg/m3 slow release fertilizer in substrate), using a potassium balanced fertilizer (N: K2O-ratio: 1:1,5). Avoid high ammonium and high nitrogen levels. Don't fertilize after mid September. In spring fertilize 100-150 ppm nitrogen of a potassium balanced fertilizer.
