History of rosemary
This aromatic herb derives its name from the Latin word Rosmarinus, meaning “mist of the sea”. It has been growing for ages in the world around the Mediterranean coast. In ancient Greece, it was believed to have magical properties that could strengthen memory. It was scattered around the grave of a loved one, to send a message to that the deceased will never be forgotten. Between the 1400s and 1600s, rosemary was used as a symbol of fidelity, love and friendship where brides would give it grooms during the wedding ceremony. Brides would also wear rosemary wreaths to their wedding. Rich couples would give each wedding guest with a rosemary twig.
In traditional medicine, rosemary was used for toothaches, headaches, gas relief and baldness. In 1987, researchers at a university in New Jersey were able to derive a food preservative known as rosmaridiphenol from rosemary. The preservative is a stable antioxidant used in cosmetics and food packaging. Rosemary was named as the herb of the year in 2000 by the international herbs association
"Let this Rosemarinus, this flower of men, ensigne of your wisdom, love and loyaltie, be carried not only in your hands, but in your heads and hearts.” - English poet Robert Herrick (1591-1674)

How to grow rosemary at home
How to grow rosemary in containers
It is extremely hard to grow rosemary from seeds. Cuttings are the preferred method. For home use, it is recommended to buy the seedling from nurseries. It sells for between 20 KES to 50 KES ($0.2 to $0.5), depending on the location. If you would like to grow your own seedlings from cuttings, please see the section on “propagating rosemary” under “How to grow rosemary for profit”
Growing rosemary in pots is rather straightforward. It requires a wide pot of at least 12 inches in diameter. This ensures that the roots have enough space to spread. Otherwise, the plant will be stunted. Clay pots are the best, but you can use any type of container
Rosemary does not do well in waterlogged conditions. The soil you use must be well draining and the pot must have drainage holes to make sure water flows out of the pot. If the roots are waterlogged, they will rot, in turn killing the plant.
Rosemary grows well in full sun. Place the plant in your compound outside or patio/balcony where it can get maximum exposure to the sun.
Rosemary in pots should be watered well, but only when the soil is dry. To test, put your finger into the soil. If the top 1-2 inches is dry, then it is time to water your rosemary. It is recommended to let the soil dry completely in between each watering.
Rosemary seldom requires fertilization, but if the plant is turning yellow or is stunted, apply well-decomposed animal manure to give it the required nutrients. Alternatively, you can use commercial fertilizers.
When cutting rosemary twigs and leaves, make sure you cut the green young shoots and not the woody part. Give it enough time to sprout new fresh shoots. You can store the shoots in the refrigerator for 2-7 days. If you want them to last longer, hang them to dry in shade. When completely dry, you can store the leaves in airtight containers.
Gardening and Landscaping using rosemary
In addition to its culinary and medical benefits, rosemary can be used to add texture, color, form and aroma to your garden. The tall varieties can be at the borders and short varieties used near walls and for creating green walls. This all-season herb can be shaped to fit into the design of your garden.
It attracts birds, bees and butterflies during the flowering season, creating a well-balanced natural ecosystem. These insects and birds help in pollination.
Rosemary can be used as a hedge plant to define perimeters of outdoor rooms. It is an excellent plant to define farm boundaries.
Given the repellant properties of rosemary, it can be planted alongside your vegetables to repel harmful pests in your organic garden.
