Rosemary

Rosemary Care Must-Knows

Rosemary needs well-drained soil to survive. It will slowly suffer in heavy and moist clays, especially during winter.

Rosemary thrives in full sun. Part sun drastically increases the likelihood of problems, such as powdery mildew, a foliar fungi that is generally harmless but unsightly, especially if you're using the rosemary in your recipes. Poor airflow and high humidity are also major contributors to powdery mildew and loss of flavor. Additionally, watch out for spider mites, mealy bugs, whitefly, and aphids.

Growing Indoors

If you're growing rosemary as an annual or a potted plant, try growing it indoors. However, this is generally no easy feat, since rosemary likes it hot and dry with plenty of sun. So in the home, make sure plants are in full sun if possible—southern exposure is best. Often, plants may not grow much indoors and will simply survive until they're back outside. Supplemental lighting can make a big difference in anything less than full sun.

Harvest Tips

The best time to harvest your rosemary is in the morning, just after any dew has evaporated. You can snip stems throughout the growing season to use fresh, or cut a bunch to dry in the fall. To use rosemary, strip the needlelike leaves from the stems and chop before adding to dishes. Store fresh rosemary up to one week in the refrigerator by placing the stems in a plastic bag with a damp paper towel.

Preserving Rosemary

To preserve rosemary for use later, air-dry the stems by bundling and hanging them upside down in a dark place with good air circulation. Once they've dried, remove the leaves from the stems and store them in an airtight container. Dried, whole rosemary can retain its flavor for up to one year. You can also freeze whole stems in a plastic bag. To use, strip as many leaves as you need from the frozen stems. Chop the leaves well before using.

Pulverize the dry leaves before adding them to dishes, herb blends, or sauces so the aromatic oils are released and they're easier to chew, as the dried leaves can be quite tough. Rosemary's texture and flavor varies throughout the season—leaves are tender in the spring, with fewer aromatic oils. By late summer, the foliage packs a more potent flavor. Toss late summer stems onto your grilling coals to infuse the meat with delicious flavor.
