Rosemary

Rosemarinus officinalis

INTRODUCTION

Rosemary grows as an evergreen shrub and is frost-hardy in most areas.

This highly aromatic herb flowers in spring and the foliage can be used for culinary purposes on a year-round basis.

Rosemary is also used for the production of some essential oils and makes some excellent infusions.

A thoroughly useful herb, especially when paired with lamb.

Soil Preparation

Rosemary requires a well-drained soil in a sunny location.

Remember, this is a Mediterranean plant, so will tolerate dry soils.

It is generally frost-hardy, but in very cold areas it may appreciate being grown against a sunny wall or fence.

Sowing & Planting

Although rosemary can be propagated from seed, you will find it easier to establish and grow if you use ready-grown plants from a herb specialist or your local garden centre.

It is also possible to take hardwood and softwood cuttings during the summer.

Transplant plants individually, and water them well while they establish.

Rosemary can be grown successfully in pots but will require more regular watering. Use a pot size of at least 10 ltrs filled with multi-purpose compost.

Growing & General Cultivation

Water well in dry weather.

Trim back plants if required in spring, never during cold weather. Only prune into the greenwood, never into mature growth as severe pruning may kill the plant.

Feeding shouldn't be necessary. 

Plants should be productive for at least 5-6 years.

Pests & Diseases

Rosemary is generally pest and disease free.

Rosemary beetles may be an issue. The beetles and their larvae can feed on the foliage from autumn until the following spring. Simply remove by hand if required.

Harvesting

Leaves can be picked on a year-round basis.

Trim the tips of the plants, but never overdo harvesting as this can have a detrimental effect on the plant.

Use fresh foliage or dry it for later use.

Rosemary makes very good infused oils and infusions.
