Propagation of Cowberry:

Seed - sow late winter in a greenhouse in a lime-free potting mix and only just cover the seed. Stored seed might require a period of up to 3 months cold stratification.

Once they are about 5cm tall, prick the seedlings out into individual pots and grow them on in a lightly shaded position in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, 5 - 8cm with a heel, August in a frame. Slow and difficult.
