|
| Sowing Time: | |
January-June for green pots; June-August for flowering in pots the following year
|
|
| Sowing Method: | |
2-3 seeds per plug
|
|
| Germination: | |
4-10 days at 20-21 °C, in media with low soluble salt levels and pH: 5.8-7.0. 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 17-20 °C. Do not let soluble salt level rise above 0,5 EC. Start fertilization at 50 ppm nitrogen in a well balanced formula. During Stage III and Stage IV fertilization levels can be increased to 100 ppm.
|
|
| Growing On: | |
3-4 weeks after sowing transplant 1-3 plants into a pack or pot (7-9 cm) and 4-5 plants into a bigger pot (10-15 cm). Plant cut flowers in 20-25 x 20-25 cm space.
|
|
| Media: | |
Use a well-drained, growing perennial substrate with 0-15 % clay, 0-10 % sand, 0-15 % organic parts (e.g. bark), 1-1,5 kg/m³ complete balanced fertilizer, 1-2 kg/m³ slow release fertilizer (3-9 months), iron-chelate, micronutrients, pH: 5.8-7.0. Field: low loamy or humus sandy soils with good drainage.
Standard fertilization: 50-80 g/m² slow release fertilizer.
|
|
| Photoperiod / Light: | |
Day length neutral plants. Armeria needs high light levels. Start with supplemental lighting in early spring for an early crop.
|
|
| Temperature: | |
Grow at 13-17 °C. In winter indoors frost free at 3-5 °C or outdoors. Outdoor fleece cover needed. In spring the plants start to grow for 10-11 weeks at 15-18 °C. Cold temperatures at 7-12 °C will increase the cultivation time. At temperatures below 7 °C the growth will stop.
|
|
| Fertilization: | |
Low-moderate fertilization levels are required. Fertilize the crop weekly with 60-80 ppm nitrogen (at 2 kg/m³ slow release fertilizer in substrate), using a complete balanced fertilizer. Avoid high ammonium and high nitrogen levels. Don't fertilize after mid September. In spring fertilize with 60-80 ppm nitrogen of a complete balanced fertilizer. Prevent magnesium deficiency by applying magnesium sulphate (0,05 %) 1-2 times and in case of iron deficiency apply iron-chelate for 1-2 times. Field: If necessary according to analysis, improve the soil with 50-80 g/m² slow release fertilizer per year, applied in several portions.
|
|
| Cut Flowers: | |
Cut flower stems can be harvested, when the petals show pigments and the staple is stretched. Vase life: 10-15 days. In the year harvest to 20-30 stems per plant. The flowers can be used for little floral arrangements.
|
|
| Cultural Hints: | |
After planting and take off treat pots with fungicide against roots diseases and clean the plants well. The plant growth is slow and the plant develops a tap root. Dry, light and airy cultivation. The roots are very sensitive to wet substrates or soils.
|
|
Hint
The cultural recommendations are based on results from trials conducted under Central European conditions. Different conditions in other parts of the world may lead to deviations in results achieved.
