|
| Sowing Time: | |
January-April for green pots and cut flower production outdoors, June-August for flowering in pots the following year, Sown all-season in greenhouse is possible
|
|
| Sowing Method: | |
2-3 seeds per plug, tap roots, can be sown in final pots or field
|
|
| Germination: | |
10-20 days at 18-24 °C, in media with very low soluble salt levels and pH: 5.5-6.5. Requires light for germination. Do not cover seeds. Keep soil slightly moist but not wet.
Avoid direct sunlight by shading seeds after sowing.
|
|
| Plug Culture: | |
From Stage II* reduce the soil moisture, but the plug should not dry out and reduce the temperature to 16-18 °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 150 ppm.
|
|
| Growing On: | |
4-5 weeks after sowing transplant 1-3 plants into packs or a pot (8-15 cm). Limonium develops a tap root. Plant cut flowers (frost free) in 40 x 30 cm space. Use nets to keep the stems upright.
|
|
| Media: | |
Use a well-drained, growing substrate with 15-30 % clay, 0-20 % parts (e.g. perlite, coconut fibres), 1-1,5 kg/m³ complete balanced fertilizer, 1-2 kg/m³ slow release fertilizer (3-6 months), iron-chelate, micronutrients, pH: 5.5-6.5. Field: sandy lightly loamy soils with good drainage.
Standard fertilization: 40-60 g/m² of a slow release fertilizer. Cover soil with mulch or fleece.
|
|
| Photoperiod / Light: | |
Day length neutral plant. Keep light level high, because high light intensity and long day improve the flowering. In winter and early spring additional assimilation light is required. Cultivation at short day needs cold temperatures for a good stem quality.
|
|
| Temperature: | |
Grow at 16-18 °C during daytime and at 13-16 °C during night or outdoors. Temperatures above 25 °C will inhibit the flower development and will increase the risk for infects with diseases. In winter indoors frost free at 3-5 °C or outdoors. Outdoor fleece cover needed. Cool temperatures at 10-12 °C for 4-6 weeks promote the flower initiation. In spring the plants start to grow for 8-10 weeks at 13-18 °C. Warm temperatures will decrease the cultivation time, but this cultivation requires high light intensity and long day.
|
|
| Fertilization: | |
Low-moderate fertilization levels are required. Fertilize the crop weekly with 100-150 ppm nitrogen (at 0 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 (N: K2O-ratio: 1:1,5). Prevent magnesium deficiency by applying magnesium sulphate (0,05 %)
1-2 times and in case of iron deficiency (above pH 6.0) apply iron-chelate for 1-2 times. Limonium tolerate high salt levels in substrate or soil. Field: If necessary according to analysis, improve the soil with 40-60 g/m² slow release fertilizer, applied in several portions.
|
|
| Cut Flowers: | |
Cut flower stems can be harvested, when the first lowers are just open. Vase life: 18-21 days. Cold storage is possible, but not necessary. Stems for dried flower production can be harvested, when the flowers are fully open.
|
|
| Cultural Hints: | |
Cultivate rather dry, because the roots are very sensitive to wet substrates or soils. Avoid overhead irrigation and high relative humidity in greenhouse during the flowering. Treat substrate and soil with fungicide against Botrytis after planting and in spring.
|
|
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.
