|
| Sowing Time: | |
November-March for green pots; April-July for flowering pots
|
|
| Sowing Method: | |
2-3 seeds per plug
|
|
| Germination: | |
7-12 days at 20-22 °C in media with low soluble salt levels and pH: 5.8-6.5. Cover seed with vermiculite, sand or substrate 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 18-20 °C. Do not let soluble salt level rise above 0,75 EC. Start fertilization at 50-75 ppm nitrogen in a well balanced formula. During Stage III and Stage IV fertilization levels can be increased to 100-150 ppm.
|
|
| Growing On: | |
4-5 weeks after sowing transplant 1 plant into a pack or pot (10-15 cm). Plant cut flowers in 30 x 40 cm space and use nets to keep the stems upright.
|
|
| Media: | |
Use a well-drained, growing perennial substrate with 0-15 % clay, 0-15 % organic parts (e.g. wood fibres, bark, compost), 1-1,5 kg/m³ complete balanced fertilizer, 2-3 kg/m³ slow release fertilizer (3-9 months),
iron-chelate, micronutrients, pH: 5.8-6.5.
Field: humus, loamy soils. Alchemilla have low demands to the soil.
Standard fertilization: 50-80 g/m2 slow release fertilizer.
|
|
| Photoperiod / Light: | |
Long day plants (13 h). Start in spring with supplemental lighting.
|
|
| Temperature: | |
Grow at 12-15 °C. In winter indoors frost free at 3-5 °C or outdoors. In spring the plants start to grow at 12-18 °C.
|
|
| Fertilization: | |
Moderate fertilization levels are required. Fertilize the crop weekly with 80-100 ppm nitrogen (at 3 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 with 80-100 ppm nitrogen of a complete balanced fertilizer. Prevent magnesium deficiency by applying magnesium sulphate (0,025 %) 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 80-100 g/m² slow release fertilizer per year, applied in several portions. N min soil value: approximately 50-60 g N/m².
|
|
| Cut Flowers: | |
Cut flower stems can be harvested, when 60-70 % of the flowers are open. Vase life: 8-12 days. Cold storage is possible. Over the year harvest 8-14 stems per plant. For dried flower production use only 100 % open flowers. The foliage can be used as ornamental material for floral arrangements.
|
|
| Cultural Hints: | |
In the 3rd year reduce the plant numbers in the rows.
|
|
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.
