We can start rosemary plants from seeds or cuttings. Generally, the seed method is difficult for an amateur and it pays off only in a large scale. If you just want some rosemary plants for your kitchen, we definitely recommend cuttings.
During spring, we carefully select young rosemary stems that are at least 3 inches (8cm) long. We then remove the leaves at the bottom half of the cuttings. We place the cuttings in a soil mixture of 20% river sand, 20% peat moss and 60% of the soil in which we will finally transplant our cuttings, so that our plants will have the time to adapt to their final environment. We may have to add a root hormone. We water the cuttings every other day, until the roots begin to grow. We then transplant our cuttings, definitely after the last frost and preferably during late spring – early summer. We have to choose a sunny spot of our field, as our rosemary plants need at least 6 hours of daily exposure to sunlight.
During their first summer months, young rosemary plants normally need frequent watering, so that they will develop strong roots. However, rosemary’s most important enemy is root rot. We have to be cautious not to over irrigate. Mature rosemary plants can rely solely on rainfall, in areas with at least 450 mm of annual precipitation.
Most farmers and gardeners do not harvest rosemary stems during the plant’s first year. From the second year onwards, we can harvest fresh rosemary stems all year round.
