Bogs, peats, margins of pools etc.

Propagation of Bog Rosemary:

Seed - sow February/March in an acid compost in the greenhouse. Surface sow or only just cover the seed and place in a lightly shaded position. The seed usually germinates in 1 - 2 months at 12C. Prick out the young seedlings into individual pots as soon as possible, they are prone to damp-off and so should be kept well ventilated. Grow them on in the greenhouse for at least their first winter and plant them out in early summer once they are 15cm or more tall. Cuttings of half-ripe wood, 5 - 7cm with a heel, July/August in a frame in a shady position. Takes 15 months. Layering in August in a semi-shady position. Takes 18 months. Division in early spring. The plants should be "dropped" beforehand. This entails digging up the plant 6 to 12 months earlier and replanting it somewhat more deeply. The buried branches will then root and form new plants when divided.
