Try to start the seeds in mid-winter. Rosemary seeds take a long time to germinate and the seedlings are slow to grow. The seedlings can be transplanted outside in mid-spring, but they need to be started inside 10 to 12 weeks before the last frost. Fill seed starters with soilless potting mix. Rosemary naturally grows in sandy and rocky soil, so the seeds will do better in a loose and light potting mix that doesn’t contain soil. Sprinkle 3 to 4 seeds into each cell. Transplant the indoor seedlings when large enough to handle into pots and grow on. Cover the seeds with a light layer of soil. Dust a very small amount of regular potting soil over the entire surface of the growing medium to just cover the seeds.


Once the seeds germinated, plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Their ideal position would be in full sun, with fertile soil that is not too wet. Space 30cm Rosemary doesn’t have a very high germination rate, so you can increase your chances of success by planting multiple seeds in each cell. Lay the seeds on top of the potting medium without pressing them down into the soil. Choose a location with full sun. Rosemary needs lots of direct sunlight to thrive. The plant will do best somewhere that gets at least 6 to 8 hours of sun every day.


As an herb, Rosemary has a lot of health benefits. One of them is; its tea may lower blood sugar, rosemary could have potential applications for managing high blood sugar among people with diabetes. Though studies on rosemary tea specifically are lacking, test-tube and animal studies on rosemary itself indicate that carnosic acid and rosmarinic acid have insulin-like effects on blood sugar. Some studies show that these compounds can increase the absorption of glucose into muscle cells, lowering blood sugar. Even taking 500 mg of oral rosemary twice daily for 1 month significantly lowered anxiety levels and improved memory and sleep quality among college students, compared with a placebo.
