The Secret to Keeping Rosemary Alive Indoors

I brought my beautiful potted rosemary inside before winter set in, only to have it die within a month.Like my other houseplants, I had given it what Mark Shepard of Restoration Agriculture calls the STUN treatment—Sheer Total Utter Neglect.The following spring I headed to the farmers’ market to replace the unlucky herb plant.The fact that she even had a pamphlet like this made me feel a little better about my murder of that previous year’s plant!If you live in USDA growing zones 7-10, where the ever-flowering rosemary shrub is used as an anchor in the perennial landscape, you probably think I’m a little cooky.In our neck of the woods, however, USDA hardiness zone 6, rosemary rarely survives the freezing winters outdoors.Rosemary is a native Mediterranean plant, hailing from a region of dry, well-drained soil and hot, sunny temps.Incidentally, other Mediterranean herbs have similar characteristics and will do well using the following suggestions: lavender and sage specifically; thyme and oregano are a bit more adaptable but will thrive with these conditions.Rosemary is called an “upside-down plant” because it likes dry roots and prefers to absorb moisture from the air through its foliage.In addition to growing your plant in a pot with a drainage hole, you need to take an extra step: Add a layer of gravel or small rocks to the drainage pan, so that the pot actually sits on top of the rocks, rather than in the pan.Because the plant likes to absorb moisture from the air, it will enjoy the water as it evaporates from the pan.For that reason, and because rosemary is an “upside-down plant”—liking dry roots but moist foliage—fill a spray bottle with water and mist the foliage once or twice a week.If your plant seems to be struggling, you can actually cover the foliage with a plastic bag for a time to hold in more moisture and to reduce the shock of the transition from outdoors to indoors.Each spring, evaluate your rosemary’s size, repot it in new soil, and prune the roots as needed.Using sharp garden scissors, cut about 2 inches of root matter off the bottom and sides before repotting it with new soil.It may seem like a lot of work to keep a potted rosemary plant happy indoors, but it’s an easy procedure once you get the hang of it. .
