Rosemary(Rosemarinus officinalis) Write a review
Light requirements Full sun is ideal. Plants tolerate part shade, but growth will be scraggly.
Planting Space 2 to 3 feet apart.
Soil requirements Plants grow best in light, well-drained soil with a pH between 6 and 7. To improve soil drainage, add builder’s sand or small limestone gravel, or tuck plants into raised beds or atop a stone wall.
Water requirements Keep soil uniformly moist, but allow it to dry out between waterings.
Frost-fighting plan Established plants can survive a few hard frosts (under 28º F). Use a frost blanket to protect newly planted seedlings from late spring frosts or prolong the growing season. In general, potted rosemary can stay outdoors in a protected location until nighttime temperatures are consistently below 25º F.
Common issues Mildew and root rot can devastate plants in humid regions. Plants can rot if mulch is piled against stems. Whitefly, scale, spider mites, and mealy bugs may attack rosemary.
Harvesting Pick leaves at any point in the growing season. Snip individual leaves or stems.
Storage Fresh stems last in water five to seven days. Refrigerate unwashed stems in a paper towel slipped into a loosely closed plastic bag that’s stashed in a warmer area of the fridge, like a door compartment. Use within 7 to 14 days. For longer storage, individually quick freeze leaves or stems on a parchment-lined tray and store in freezer bags, or freeze in ice cubes.

Rosemary, a member of the mint family, has been cultivated for its medicinal properties—believed to cure ailments of the nervous system—in the Mediterranean since 500 B.C. With flavorful hints of lemon and pine, rosemary is now popular around the globe and is used for purposes ranging from flavoring foods to scenting cosmetics. A good source of Vitamins A, C, and Manganese, rosemary helps the body metabolize proteins and sugar, contains antioxidants that protect against cell damage, boosts the immune system, and helps the formation of collagen in the body. As an added perk, rosemary’s needlelike leaves keep gardens green and fragrant year-round.
