Planting rosemary is not complicated, and if you follow a few steps, you may be on your way to broadening your kitchen garden.

  • Rosemary can be grown from seeds, but the germination process will take time. So, start from plant cuttings of established plants.
  • Seeds or cuttings grow indoors within 8-10 weeks in good condition and can be ready for outdoor planting in 8 weeks.
  • It is advisable to plant seeds and cut them indoors for 8-10 weeks before the last frost in spring.
  • Choose and prepare the plant site. Make sure to choose a location with full sun.
  • The site must also have well-draining soil. Rosemary does not like too much moisture and being constantly wet.
  • There must be enough room for plants to grow as, on average, the plant can grow up to 4 feet in height and width.
  • Plant near vegetables like cabbage, sage, beans, or other herbs.
  • Plant the seeds and cuttings in well-drained soil. The soil temperature must be around 70 degrees centigrade.

How to Grow Rosemary

How fast does rosemary grow? How much sunlight does rosemary need? It is not difficult to grow rosemary. You can either grow rosemary in a pot or from seeds or cuttings in your garden. It is easier to propagate rosemary cultivation from stem cuttings rather than harvesting a new plant or seeds. Rosemary likes its roots to be undisturbed, so if you grow it in your garden, dig it in a pot for winter and preserve it.

  • When indoors, place the pot in a cool yet sunny location with more humidity.
  • Place small pebbles or stones on a plate, add water and keep the potted rosemary on top of the plate.
  • Bring the pot to the sink to water rosemary plants and let the excess water drain out of the pot.
  • Use a good potting mix for good drainage. You can make your potting mix ( 2 parts potting mix two parts peat, one part sand, and one part compost). Alternatively, you can use the same potting mix used for cacti.
  • Plant them in early spring and space seeds 1 inch apart covered with a little potting mix if you want to grow rosemary from seed. Keep the mixture a little moist and not very wet.
  • Cover the seeds with plastic wrap and keep the temperature to 60-70 degrees Fahrenheit. Place the seeds under intense sunlight.
  • As you see the seeds germinating, remove the plastic and continue to grow the plants until you see several sets of leaves. Transfer each seedling into its pot or ground once the frost has disappeared.
  • To grow rosemary from cuttings, cut about 3 inches of a stem from a fertile rosemary plant. Trim the leaves from the lower part of the stem (about 1½ inch) and dig that end into the soil about 3-4 inches.
  • Keep the soil around the planted cutting moist and make sure not to make it too wet.
  • Place the pot in a sunny location where the temperature will be about 60-70 degrees Fahrenheit. Keep the cutting rooted in the soil for about eight weeks.
