Rosemary is an evergreen shrub that can grow up to 1.5 metres high. It is very easy to cultivate because it is draught tolerant. It is one of the best herbs to use in the kitchen, a wonderful addition to any garden and it has various medicinal uses.
Rosemary can grow in a variety of soils, sandy loam preferred because good drainage is important and lots of sun. Rosemary can also grow in containers outside or in a sunny window.
How to Plant
Rosemary can be grown from seeds, cover lightly with soil and keep slightly moist until they are established with a few sets of leaves. To speed up the process you can soak the seeds overnight and germinate them in a small greenhouse or covering the container with plastic.
How to Water
Once the small plants are established watering Rosemary will vary according to your local climate, generally in warmer areas water only once a week or less and do not water during the rainy season.
Rosemary goes well with other herbs and is a great addition to any garden because it can draw bees year around (in warmer climates). In particular it is said to go well with sage, thyme, beans, carrots and cabbages.

Harvest Rosemary throughout the year to encourage growth and to shape your plants, strip the needle-like leaves off the main stem and use as required.
The green needle-like leaves are used and you can eat the flowers.
