Propagation
Sow seeds when ripe and in cold climates place in a cold frame to germinate.

Divide established clumps (rhizome) during autumn or early spring.

Note:
It has been used for hundred of years for herbal remedies such as tea from the leaves for diuretic purposes. The roots and the flowers produce red and yellow dyes respectively and use for colouring cheese or ladies hair hence the common name Maid's Hair.
It is also thought that during biblical times the Virgin Mary used Yellow Bedstraw to prepare the manger in Bethlehem.
