Rosemary is a fragrant, versatile herb with many uses. Rosemary can grow as a hedge, be used fresh in culinary dishes or dried for use in potpourri, bath salts or for preparing meals. Rosemary is a hardy, heat-loving perennial that grows woody stems and needle-like leaves. Rosemary can be grown in pots or in the ground so long as it is in full sun and the soil is loose and moist. While the rosemary can be allowed to grow bush-like, some herb growers prefer to grow them into a topiary shape.
Plant your rosemary seedling in a pot with drainage holes and filled with potting soil. Plant rosemary in the ground, if desired, but add 2 to 3 inches of garden soil to the bed area and mix it in. Set the plant in a hole only as deep as it is in its existing container and in an area that receives full sun at least six hours a day.
Wet the soil around the rosemary plant without drenching the ground or pot so heavily that it won't drain. Water the soil to 1 inch deep when the soil is dry, which may be more frequent for potted plants.
Feed your rosemary herb at planting with an all-purpose 10-10-10 fertilizer according to the manufacturer's instructions. Repeat feedings every month to encourage good foliage growth and more herbs.
Collect herbs by clipping sprigs or just a few leaves with clean herb scissors. Collect along green stems rather than cutting into woody portions of the plant. Use the rosemary immediately or hang it upside down to dry inside for two to three weeks before storing.
Prune the rosemary with hand pruners in the spring after flowering. Cut stems individually above woody portions as needed to shape the plant as desired. Strive for a more boxy shape, or just clip the ends to encourage dense growth with a more natural shape.
