Rosemary is a perennial evergreen shrub with blue flowers. It is an aromatic and distinctive herb with a sweet, resinous flavor. Here’s how to grow your own rosemary plants!
Hailing from the shores of the Mediterranean Sea, rosemary does best in warm areas with fair humidity, where it can grow into a shrub several feet in height. In fact, rosemary grows so vigorously in ideal conditions that it can become a bit of a burden if not managed properly!
This herb can be grown outdoors as a perennial shrub in Zones 7 and warmer. In colder areas, it should be kept in a pot and brought indoors for the winter.
Rosemary is often used for seasoning poultry, lamb, stews, and soups.
When to Plant Rosemary
Rosemary can be grown from seed, but germination rates are generally quite low and seedlings are slow to grow. Therefore, it’s strongly recommended to start new rosemary plants from cuttings taken from established plants. Cuttings grow quickly in good conditions and should be ready for outdoor planting in about 8 weeks.
Plant seeds/cuttings in well-drained soil. For best growth, the soil temperature should be around 70ºF (21°C).
How to Grow Rosemary
Water rosemary plants evenly throughout the growing season, but be careful not to overwater.
Prune regularly so that plants won’t get lanky.
For fresh rosemary in the winter, grow the plant indoors in a pot (or take a cutting from an outdoor plant and keep a second indoors). Be sure to put it in bright light and protect it from cold drafts.
Rosemary that’s grown in the ground does not transplant to containers well, so consider growing it in a container that can be brought inside during the colder months.
Be sure to get cuttings or divide the plant for next season if it won’t survive winter in your area.
How to Harvest Rosemary
Snip off stems to use fresh, or hang them in the kitchen for dried rosemary.
