Propagating multiple rosemary plants from cuttings. Growing Rosemary Herb

Rosemary is one of the most decorative herbs and is well worth growing for its appearance alone. Dependent on the variety, it has small, profuse flowers appearing in late spring which range from dark blue through pale blue right down to white.
Site and Planting
Rosemary prefers a light soil, a sandy soil will fully satisfy its meagre feeding needs. Having said that, rosemary is tolerant of most soil conditions as long as they are not water-logged. Rosemary prefers a slightly limey soil (the opposite of acid) because this results in smaller plants with more fragrant leaves. True to its origins, rosemary prefers sunny and sheltered conditions. It will stand severe frosts if conditions are not windy and wet as well.
Propagation
Seeds are readily available from most major seed merchants, although only for Rosmarinus officinalis - we have not seen any seed for sale for the other varieties. Sow the seeds in potting compost around mid-May time and place in a sheltered position in the garden - unfortunately you will only achieve a success rate of about 15%. The seedlings may well take up to 2 months to appear so don't give up hope until maybe 3 months has past.
The best method of propagating Rosemary is by taking cuttings, mid-May or June being the best time.
Select a healthy looking plant with lots of new growth on it.
Use a sharp knife to take 7.5cm (3in) cutting from young shoots either just below a leaf joint or torn off at the stem.
If tearing off a cutting, trim the "heel" to remove most, but not all of it.
Strip of the leaves from the lower 4cm (1½in), pulling them off with your fingers.
Fill a 7.5cm (3in) pot with standard potting compost and insert one or two cuttings in each pot. Water the compost from below and place in a propagator or cover it with a plastic bag.
A temperature of 15°C to 20°C (60°F to 70°F) is needed for the cuttings to root.
A windowsill out of direct sunlight is an ideal position. They can be transplanted to their permanent position when they have rooted, this will be in roughly 2-4 weeks time.
