Sowing & Care of Coriander 'Jantar'
Sow directly outdoors from April to June in loose, well-drained soil. Sow the seeds 0.5 to 1 cm deep, press down lightly and keep evenly moist. Germination takes around two to three weeks at temperatures between 16 and 20 °C. Space rows about 25 to 30 cm apart and thin seedlings within the row to 10 to 20 cm.
For particularly high seed yields, 'Jantar' can also be sown in late summer to early autumn, from late August to mid September. The aim of autumn sowing is for the plants to reach a strong rosette stage before winter and resume growth very early in spring. As a result, they flower earlier and often produce higher seed yields than spring sowings.
Important: Coriander is an annual and only moderately frost tolerant. It tolerates light frosts but is not winter hardy and is sensitive to prolonged frost periods or severe sub-zero temperatures. In exposed sites, waterlogged soils or open, windy positions, autumn sowings may fail. Well-drained soils, sheltered locations and, if necessary, light protection with horticultural fleece or mulch during heavier frost are recommended.
For the best leaf quality, choose a partially shaded position, for maximum seed production a sunny site. Water evenly but avoid waterlogging, which is particularly problematic in autumn and winter. Leaf harvest begins from June or in spring after overwintering. Seeds are harvested from late July to September once the umbels turn brown. For drying, hang the plants upside down in an airy place and then rub out the seeds.
