Rosemary is a low-maintenance herb native to the Mediterranean and Asia. While rosemary started from seed has a relatively low success rate (only 15 percent), rosemary can be easily transplanted into your garden from a starter plant in early April. Choose a healthy, disease-free plant from your nursery to begin growing your own rosemary in your garden. With a bit of preparation and care, you can harvest fresh rosemary sprigs for your cooking and craft projects throughout the year.
Choose a sunny and sheltered spot to plant your rosemary. Dig a hole slightly larger than the container your starter plant is in.
Place a half inch of sand and a handful of compost in the bottom of the hole and mix with the soil. This will provide your rosemary plant with adequate nutrients and drainage.
Turn the rosemary pot upside down and gently tap on the bottom to ease the plant out of the container. Place the plant in the hole and fill in around the roots with soil. Rosemary does not like to have its roots disturbed, so take extra care when handling the root bundle.
Water the plant thoroughly after planting and every one to two days until the roots establish in the soil. Continue to water your plants during dry spells
Prune back the sides of your rosemary plant after the first flowering in early summer.
