Water

Water moderately during the growing season and reduce the frequency in winter. It's best to water deeply and infrequently, allowing the soil to dry out slightly between waterings.

Sunlight

Provide it with at least 6 hours of full sun per day to thrive. It can tolerate partial shade, but it may have fewer flowers and flavor. Indoors, place rosemary near a bright window that receives direct sunlight for several hours a day.

Soil

Rosemary prefers light and sandy growing media that are slightly acidic to neutral. It can also grow in alkaline soils, but it may have yellow foliage and poor growth. To improve the soil quality for the herb, you can add compost or perlite.

Fertilizer

The herb can benefit from a light application of a balanced organic fertilizer in spring and summer. When growing indoors, feed the plant once a month with a diluted liquid fertilizer during the growing season.

Pruning

You can prune the herb anytime during the year, except when it is blooming or dormant. This helps to maintain its shape and size and to encourage new growth and flowering.

Propagation

Three ways to propagate the herb: by seed, cutting, or layering. Because the former is slow and difficult to germinate, it's best to multiply cuttngs, which is far easier. Take a cutting from healthy stems and remove the lower leaves, then place it in water. When you see signs of root development, place the cutting in moist sand and keep it in a warm and humid place until fresh sprigs emerge.
You can also layer by bending a low-growing branch to the ground and covering part of it with soil. Secure the branch with a stone and leave until it roots. You can then cut the new plant from the parent plant and transplant it.

Thrives in

Warm and dry climates with moderate humidity.

Toxicity

Rosemary is generally safe to consume in small amounts as a herb or a tea. But, it may cause allergic reactions in some people who are sensitive to it or have asthma. It may also interact with some medications like blood thinners or anticonvulsants. The herb should be avoided by pregnant or breastfeeding women as it may stimulate uterine contractions or affect milk production.

I'm an enthusiastic gardener. I learned the art of growing my own food using sustainable gardening techniques from my father, which I still find effective for healthy plant growth. Gardening has become one of my best hobbies ever since I realized its benefits beyond growing my own food. Through experimenting and connecting with nature, I've found gardening to be a therapeutic and relaxing practice.
